Opis:
This paper presents a comparison of the deformations and residual stresses in gear wheels after vacuum carburizing process with quenching in high-pressure nitrogen and oil. The comparison was made on a medium-sized gear wheels, made of AMS6265 (AISI 9310) steel. This steel is applied in the aerospace industry for gears. The study has provided grounds for an assessment of the effect of the method of quenching on the size of deformations. Compared to oil quenching, high-pressure gas quenching following vacuum carburizing resulted in more uniform and smaller deformations.

Opis:
W artykule przedstawiono wyniki badań wpływu składu chemicznego atmosfery nawęglającej acetylen+wodór na jej zdolności penetracyjne i intensywność nawęglania próżniowego powierzchni głębokich, nieprzelotowych otworów w stali 16HG. Analizie poddano atmosferę nawęglającą acetylen+odór zawierającą od 50% do 100% acetylenu. Wszystkie parametry procesu nawęglania próżniowego zostały zaprojektowane z wykorzystaniem pakietu symulacyjnego SimVacTMPlus, dla przyjętych parametrów warstwy nawęglanej, tj. powierzchniowego stężenia węgla IcSurf=0,94%, efektywnego stężenia węgla IcEfekt=0,6% oraz efektywnej grubości warstwy nawęglanej DcEfekt=0,5 mm. W ramach badań wykonano rozkłady twardości wytworzonych warstw nawęglanych, określonych efektywną grubością na poziomie twardości 550 HV, a także określono głębokość otworu, na której proces nawęglania przebiegał efektywnie.
This article presents the research results of the influence of chemical composition of the carburizing atmosphere acetylene + hydrogen on the penetration ability and intensity of the vacuum carburizing of deep surfaces of blind holes made in 16HG steel. The carburizing atmosphere acetylene + hydrogen containing from 50% to 100% of acetylene was analysed. All parameters of the vacuum carburizing process were designed with the use of SimVacTMPlus simulation software, taking into consideration the parameters of carburizing layer, ie. superficial concentration of carbon IcSurf = 0.94%, effective concentration of carbon IcEfekt= 0.6% and effective thickness of carburizing layer DcEfekt = 0.5 mm. Within the framework of the research hardness profiles of the produced carburizing layers were performed which effective thickness was determined by the hardness level of 550 HV. Also the depth of the blind hole where the carburizing process proceeded effectively was defined.

This paper presents the results of a study aimed at determining the residual stress which results from developing the surface layer by low-pressure and conventional carburizing and grinding of 17CrNi6-6 steel. A synergistic effect of thermochemical and abrasive treatment was examined on ring samples used to study residual stress by Davidenkov’s method. Samples were subjected to vacuum carburizing and conventional carburizing, which was followed by grinding with a 38A60K8V aloxite grinding wheel and a CBN grinding wheel - RNB80/63B75V. The following cutting fluids were used during the grinding process: oil emulsion 5%, supply rate ca. 20 l/min, Micro5000 oil supplied at the minimum quantity lubrication (MQL) of ca. 25 ml/h, dry machining. The study determined the effect of the type of grinding wheel and the cooling and lubricating agent on the distribution of residual stress in the surface layer. The best effects of grinding with respect to the residual stress were achieved with flood cooling with oil emulsion and grinding with a CBN grinding wheel.

Opis:
One of the many advantages of low pressure carburizing (LPC) is that it can be combined with high-pressure gas quenching. This makes it possible to achieve workpieces with pure metallic surfaces, less distortion hardening, and, above all, it allows a more reliable and repeatable treatment than conventional oil quenching. This article presents a study of the distortion rate of workpieces carburized at low pressure then quenched in nitrogen at 1.4 MPa. By comparing the distortion which takes place during the carburizing stage only and the carburizing combined with post-carburizing heat treatment it will be possible to assess the distortion rate and its causes at the different stages of the heat treatment process.

Opis:
Carburizing is one of the most popular and wide used thermo-chemical treatment methods of surface modification of tool steels. It is a process based on carbon diffusive enrichment of the surface material and is applied for elements that are supposed to present higher hardness and wear resistance sustaining core ductility. Typical elements submitted to carburizing process are gears, shafts, pins and bearing elements. In the last years, more and more popular, especially in highly advanced treatment procedures used in the aerospace industry is vacuum carburizing. It is a process based on chemical treatment of the surface in lower pressure, providing much higher uniformity of carburized layer, lower process cost and much lesser negative impact on environment to compare with conventional carburizing methods, as for example gas carburizing in Endo atmosphere. Unfortunately, aerospace industry requires much more detailed description of the phenomena linked to this process method and the literature background shows lack of tests that could confirm fulfilment of all needed requirements and to understand the process itself in much deeper meaning. In the presented paper, authors focused their research on acetylene flow impact on carburized layer characteristic. This is one of the most crucial parameters concerning homogeneity and uniformity of carburized layer properties. That is why, specific process methodology have been planned based on different acetylene flow values, and the surface layer of the steel gears have been investigated in meaning to impact on any possible change in potential properties of the final product.

Opis:
The aim of the experiment described in the paper was to determine the effect of selected conditions of abrasive machining on the size and distribution of microhardness and residual stresses developed in the technological surface layer of flat specimens made of 20MnCr5 steel. The specimens were subjected to single-piece flow low-pressure carburizing (LPC) and high-pressure gas quenching (HPGQ) in a 4D Quenching chamber, in order to achieve the effective case depth of ECD=0.4 mm. This was followed by grinding the specimens with Quantum and Vortex alumina grinding wheels made by Norton. Cooling and lubricating liquid were supplied to the grinding zone in both cases by the flood (WET) method and by the minimum quantity lubrication (MQL) method. The measurements for each specimen were made twice - after the thermo-chemical treatment and after the grinding. Microhardness and residual stress was measured by the X-ray method sin2Ψ. The final part of the article provides an analysis of the measurement results and presents conclusions and recommendations for further studies.

Opis:
Gears, due to their complex shape, carried load and required accuracy are ones of most complex aircraft engine parts. Single tooth damage usually breaks the power transmission and causes failure of the entire gear system. Adequate sustainability and guarantees of transmission is therefore a condition for secure operation of whole device. Particularly high requirements for reliability are put to transmissions used in the aerospace industry. Due to the loads which are transmitted through the gears, the materials used by the manufacturer must have not only high strength but also show the abrasion resistance of the surface layer and the ductility of the core. Proper parameters matching allows to create an element that can operate at higher stresses and loads. In addition, factor strength and abrasion resistance of the surface layer has a significant impact on the life of the gear. Thermo-chemical treatment of industrial gears is a fundamental process, which gives them adequate mechanical properties regarding loads they carry and the surface conditions of work. Among many methods of thermo-chemical treatment used in the industry, the most distinctive are innovative technologies designed to reduce process costs and being more environmentally friendly. The most promising methods in the discussed field are vacuum carburizing and high-pressure hardening, which by their specification of work significantly reduce the emission of CO2 and the duration of the process, without reducing the quality of the final product. The main aim of the paper is to present criteria for selection of heat treatment parameters as a part of thermo-chemical treatment process performed using vacuum methods. Proper heat treatment parameters are crucial in programming of some of final material characteristics as grain size and retained austenite morphology.

Przeanalizowano właściwości użytkowe warstwy wierzchniej (naprężenia własne, mikrotwardość, mikrostrukturę). Określono równocześnie wpływ wyżej wymienionych parametrów na odporność na zużycie i współczynnik tarcia materiału przy ślizganiu.

The properties of the surface layers obtained in the conventional and vacuum carburising processes and after grinding with modern grinding wheels are presented in this paper. Service properties of the surface layers were analysed (residual stresses, microhardness and microstructure). The influences of aforementioned parameters on wear resistance and friction coefficient during sliding were determined. Tests revealed that the process of vacuum carburising followed by CDN grinding gives much better service properties.

Simulation is used today in many contexts, such as simulating technology to tune or optimize performance, safety engineering, testing, training, education, and entertainment. In some industries, simulations are commonly used, but in heat treatment this is rather an exception. The paper compares the simulation of carburization and nitrocementation of 16MnCr5 steel with a practical application. The aim was to determine the applicability of chemical heat treatment simulation. We were looking for an answer to the question: to what extent can we rely on the technological design of heat treatment? The software designed the heat treatment technology. He drew the technological process of chemical-thermal treatment of 16MnCr5 steel. The thickness of the cementite layer was 1 mm and the nitrocementation 1.2 mm. Changes in mechanical properties were observed. Cementing, nitrocementing, hardness, microhardness, metallography, and spectral analysis were practically performed. This article describes the benefits of simulation, speed and accuracy of the process. The only difference was in determining the carbon potential. The simulation confirmed the practical use and its contribution in the technological process.

Opis:
Purpose: In this paper, the impact of hardening temperature on the quenching distortions which occur during low-pressure carburizing with gas quenching - using the individual quenching method - was analysed. Design/methodology/approach: The reference elements were subjected to carburizing at 980°C, followed by gas quenching at temperatures of 860°C, 920°C and 980°C. The geometrical measurements of the elements were made before and after the chemical treatment and the size of the quenching distortions of their geometrical parameters was determined. Findings: It was demonstrated that a high temperature of quenching has an unfavourable effect on changes in cylindricity and roundness parameters but, at the same time, reduces the size of distortion of outer parameters. Low temperature quenching reduces quenching distortions of cylindricity and roundness parameters while increasing the distortion of outer dimensions. Research limitations/implications: Based on the research and analysis carried out in this work, it was found that the use of lower quenching temperature is justified in economic and quality terms. Practical implications: In the case of the aviation or automotive industry, very high quality of manufactured elements along with a simultaneous reduction of their production costs is extremely important. Maintaining the dimensions of the elements during heat treatment is extremely difficult. The tests allowed to determine the optimal hardening temperature, which brings with it acceptable deformations. Since it is easier to “repair” the outer geometrical dimensions (diameter, thickness), it seems that quenching from lower temperatures is a more favourable process. Originality/value: The conducted tests allowed to determine the most favourable conditions for hardening elements from the automotive industry, taking into account the occurring deformations and their subsequent processing

Purpose: The purpose of the work is a complex review of methods applied industrially as case hardening. The paper contains an overview of scientific and development works on surface case hardening methods, especially carburising and quenching, described in the literature from 2001-2020. Design/methodology/approach: State-of-the-art was reviewed by a critical review of the world literature published in 2001-2022, including theoretical work, scientific research, and industry reports. An additional examination of the state of the art was conducted in terms of patent works. Findings: The period of 2001-2020 was a time of intensive work on the modernisation of case hardening techniques to improve the repeatability and uniformity of the produced layers and minimise deformations after hardening. Developing computing technologies have played a large part in this progress. New technologies have also been developed. Research limitations/implications: The review of papers and patent databases was limited to databases providing English-language content options. Practical implications: Case hardening is a crucial stage of steel heat treatment in almost every industrial branch: mechanical, tool, automotive, railway, and aviation. Originality/value: A synthetic review of case hardening methods was presented, particularly carburizing and quenching methods; it also analysed the possibilities and directions of their development.
