Opis:
Ailments linked to back pain is a serious problem not only medical but also social. Not only elder people but also people in working age suffers from problems related to spine pain. The most common disorders of the spine are pain syndromes of the lumbar part where center of gravity of the human body is located and w here major forces are acting on the vertebrae and intervertebral discs. The market currently offers a variety of spinal implant solutions (FIG 1). In the Metal Forming Institute there is realized research Project entitled Investigations and spine implants functionality evaluation in material and tribological aspects. In the frame of the Project it was designed and manufactured special simulator adapted for intervetebrals pine discs implants investigations. Simulator scheme is presented on FIG. 2. Main goals of the realized Project are: • Investigation of friction-mechanical processes during implant usage. • Evaluation of wear intensity of various types of intervertebral discs and investigations of appearing wear products. • Selection of optimal material and surface machining method providing minimal wear of intervertebral disc elements wear. For experiments there was implant designed by K. Skalski and J. Skoworodko selected [1], which consists of 3 elements: upper liner, lower liner and nucleus pulpous (FIG. 3). Actually there are 3 types of friction couple materials tested: 316L steel - polyethylene UHMWPE – 316L steel, titanium alloy Ti6Al4V – polyethylene UHMWPE and nitrided Ti6Al4V titanium alloy – polyethylene UHMWPE. In fluence of number of cycles on friction coefficient, surface roughness and poliethylene linner thickness change illustrates FIG. 4. As it results from performed investigations, too high hardness level of metal elements (upper and lower clasps) provides to accelerated wear of the polyethylene part. New challenge is application of “metal-metal” friction couple.

Opis:
The article deals with the experimental detection of the tribotechnical parameters for two different types of sliding bearings which are intended for operation without an additional lubrication due to the increasing requirements in ecology and environment. The dominant tribotechnical parameters of the self-lubricating bearing are the coefficient of friction and temperature. To determine these parameters, an experimental method was applied in this paper. The introductory part deals with materials of self-lubricating sliding bearings, their properties and usage. The experimental part consists of the evaluation of friction characteristics and geometric change of a surface after sliding pairs were being worn. Experimental examined sliding pairs comprise a sliding bearing and the shaft. The aim of this research was to determine the effect of radial force on tribotechnical parameters in order to predict the behavior of examined sliding bearings in real operating conditions.

This paper presents 3D FEM simulation results performed for the power law and JC (Johnson-Cook) material constitutive models for two sets of friction parameters. The friction conditions were tested using pin-on-disc tribometer. Machining tests were carried out using carbide cutting tools coated with a TiAlN monolayer without coolants. The selection of machining conditions was based on real production data. In addition, a real CAD model of the cutting tool insert was implemented. Moreover, an advanced technique of meshing the cutting edge and the grooved rake face was applied. The simulations include cutting forces and cutting temperature. Finally, FEM simulations were compared with measurements in order to improve the simulation strategy.

Opis:
Semi-metallic brake pads are quite a good choice for performance-driven automotive industries, because of improved braking performance in a more comprehensive range of temperatures. In this study, a semi-metallic brake pad is fabricated through a powder metallurgy processing technique with two compositions of powders with a different weight ratio of Copper (Cu), Iron (Fe), flash, Aluminum oxide (Al2O3), Barium sulfate (BaSO4), Phenolic resin, Low-Density Polyethylene (LDPE), Graphite for automotive application. A well-distributed composition was indicated by the microstructure, which exhibited a uniform dispersion of hard particles throughout the matrix. BP-20Cu-20Fe specimen exhibited a high hardness value of 171Hv. Under higher loads of 70 N, the specimen BP-20Cu-20Fe showed excellent wear resistance, with a low wear rate of 1.072×10-6 g/Nm. On the other hand, specimen BP-20Cu-20Fe showed a notable 35% increase in friction coefficient when the load was increased from 30 N to 70 N.The surface morphology, elemental distribution, and worn surface features and characteristics are examined using advanced instrumental techniques.

Opis:
Korzystając z jubileuszu Szkół Tribologicznych zaproponowano w artykule rozważenie kilku kwestii, które zwykle, wypierane przez bieżące zadania, umykają uwadze tribologów. Przedstawiono ewolucję wiedzy o tarciu prowadzącą do wyodrębnienia się tribologii jako samodzielnej dyscypliny naukowej. Przyjęto przy tym dwa założenia wiodące: 1. Nie rozważano kwestii naukowości tribologii, reprezentując pogląd, że nie można mówić o naukowości jakiejś dziedziny działalności; naukowe lub nie mogą być efekty działalności, nie zaś sama ta działalność; 2. Przyjęto również tezę, że ewolucja tribologii wynikała z poznania atrybutów tarcia jako wszechobecnego zjawiska fizycznego i nieustannych wysiłków zmierzających do ograniczenia negatywnych skutków jego działania i w miarę możliwości wykorzystania go jako elementu procesu służącemu dobru człowieka. W artykule omówiono również zagadnienie, a raczej grupę zagadnień obejmujących zbiór poglądów prezentowanych przez tribologów i konsekwencji tych opinii dla rozwoju tribologii i jej pozycji wśród dyscyplin naukowych. W tej części artykułu rozważono niektóre kwestie metodologiczne tribologii oraz obecny stan jej struktur wewnętrznych. Przeprowadzone rozważania nawiązują do jubileuszowego charakteru obecnej Szkoły Tribologicznej.
Thanks to opportunity of Tribology Schools jubilee, in the article are presented the consideration of same issues that usually are driven out by current tasks and escaped tribologiests notice. The friction knowledge evolution leading to single out tribology as self-contain scientific discipline is presented. Deliberations are based on two assumption: 1. The tribology scientificity issue isn’t deliberated, because author thinks that discipline couldn't be considered as scientific or not, there are effects of discipline activities that could be considered in such way. 2. Tribology evolution resulted from friction attributes cognition and identification as omnipresent physical phenomenon and from sustained research aiming at limitation of friction negative effects or make the most of friction as the element of controlled process. The article also presents the issue, or rather group of issues encompasses tribologiests' views and such views consequences for tribology development and its position among scientific disciplines. In this part of article there are considered same methodological questions of tribology and current state of its interior structure. The presented deliberations refer to jubilee character of Tribology School.

Opis:
Investigations include alloying the PMHSS6-5-3 steel surface layer with carbide and ceramic powders WC, VC, TiC, SiC, Si3N4 and Al2O3, using the high power diode laser (HPDL). Laser treatment is especially promising for solving contemporary surface engineering problems making it possible to focus precisely the delivered energy in the form of heat in the surface layer. The structural mechanism was determined of surface layers development, effect was studied of alloying parameters, method on structure refinement and influence of these factors on the mechanical properties of surface layer, and especially on its abrasive wear resistance. The fine grained martensite structure is responsible for hardness increase of the alloyed layer. The tribological wear relationships were determined for laser treated surface layers, determining friction coefficient, and wear trace shape developed due to the abrasive wear of the investigated surfaces. Comparison of the laser treatment parameters and tribological properties of surface layer after remelting and alloying with hard particles of the PMHSS6-5-3 steel using the high power diode laser to obtain the optimum service properties is the outcome of the investigations carried out.

Opis:
Titanium and its alloys are one of the most popular metallic materials used in medicine for many years. Their favorable mechanical properties, high corrosion resistance and good biotolerance in an environment of tissues and body fluids, cause that they are widely used as construction material of orthopaedic dental and neurological implants. Their disadvantages are poor tribological properties manifested by high coefficient of friction, scuffing and tendency to formation of adhesive couplings. In many research centers the works on improving the unfavorable tribological properties of titanium alloys are conducted. They rely on the use of modern methods of surface treatment including the thermo-chemical methods (nitriding, carburizing, oxidation) and the synthesis of thin films using PVD and CVD methods. In the presented work the glow discharge oxidation was applied to improve the surface properties of two-phase Ti6Al4V and Ti6Al7Nb titanium alloys. The results include a description of the obtained structure of the surface layer, surface topography, micro-hardness, wear ratio and corrosion resistance. The obtained results indicate changes in the surface layer of the material. The surface hardness was more than doubled and the depth of increased hardness region was up to 85 microns. This, in turn, several times decreased the wear rate of the modified materials while reducing the wear rate of the countersample. At the same time the carried out thermo-chemical treatment did not cause any structural changes in the core material. The oxidation process preferably influenced the corrosion properties of titanium alloys. Both, significant increase in the corrosion potential (approx. 0.36 V), as well as increased polarization resistance were observed. The modified surfaces also retained a high resistance to pitting corrosion.

Selection of laser operating conditions is discussed, as well as beam face quality after remelting, hardness, micro hardness test, wear resistant. Remelting of the steel with introducing into liquid molten pool the alloying additions in the form of ceramic powders, causes significant increase of properties of surface layer of investigated steel in comparison to its analogical properties obtained through conventional heat treatment, depending on the laser beam power implemented for remelting. The increase of hardness of surface layer obtained throughout remelting and alloying with carbides by high power diode laser is accompanied by increase of tribological properties, when comparing to the steel processed with conventional heat treatment.

The study of the thermal, wear and corrosion properties of developed nanocomposite coatings of Zn-Al2O3 and Zn-Cr2O3 was carried out. The coatings were produced by electrodeposition technique from chloride acidic bath. Laboratory tube furnace was used for the thermal analysis. The wear test was performed using CETR tribo-tester dry reciprocating tester. The hardness properties were investigated using diamond base Dura microhardness tester. Scanning electron microscope (SEM) affixed with energy dispersive spectrometry was used to study the morphological characteristics, before and after wear deformation. The corrosion degradation behavior was observed using linear polarization technique in 3.5% NaCl. In all the interaction, the effects of the incorporated Al2O3 and Cr2O3 nanoparticulates on zinc rich coatings were found to have an excellent influence on the wear, corrosion and thermal stability properties. The fabrication and properties exhibited by the alloys were therefore found to be satisfactory and shows good predictability and applicability.
