Opis:: Purpose: The purpose of the work is to demonstrate the possibility of using a femtosecond laser for forming surface layers with an adjustable microstructure on the surface of TRIP steel 03X13AG19, and processing the obtained images using digital complexes. Design/methodology/approach: A laser treatment of TRIP steel (03X13AG19) with pulses of femtosecond duration was carried out in a melting mode. The source of the radiation is a femtosecond titanium-sapphire Ti:Al2O3 complex consisting of a predefining femtosecond generator “Mira Optima 900-F” and regenerative amplifier Legend F-1K-HE. Peculiarities of the surface structure of irradiated samples were studied using a Solver P47-PRO atomic force microscope. The structural-geometric parameters of the surface of the investigated steel treated with the femtosecond laser were determined using the software package Nova 1.0.26.1443 and the functions of the Image Analysis. Microstructural analysis was performed using a raster electron microscope JSM 6700F and a METAM-1P microscope. In this work, the digitization of images of microstructures obtained as a result of surface irradiation by highly concentrated energy streams of femtosecond duration has been carried out. The analysis of the surface structure of laser-structured materials was carried out using a metallographic complex with the software ImProcQCV. Findings: It has been revealed that the predetermined change of the laser treatment mode changes the microrelief and the shape and size of the fragments of the surface structure of the investigated steel. The use of digital image processing allowed to generalize the morphological features of the surface structure, to assess in detail the character of the microrelief, and to monitor under in-situ mode the structure and properties of the surface of the material being studied. Research limitations/implications: The obtained research results can be applied to stainless steels of various structural classes. Practical implications: Surface digitization significantly reduces the time for research, improves the quality and accuracy of the data obtained, makes it possible to conduct in-situ researches with the further implementation of the results using the Internet of Things technologies. Originality/value: A comprehensive approach is proposed for the estimation of parameters of laser-induced periodic surface structures (LIPSS) using a metallographic complex with the software ImProcQCV.

Opis:: Purpose: The paper presents the issues of designing the maintenance of materials and products in accordance with the idea of Industry 4.0. The author's views on the need for augmentation of the Industry 4.0 model were also presented, as well as the author's original concept that hybrid activities in predictive maintenance and condition-based maintenance should be preceded by designing material, maintenance & manufacturing 3MD at the stage of the product's material designing and technological designing. The 3MD approach significantly reduces the frequency of assumed actions, procedures and resources necessary to remain the condition of this product for the longest possible time, enabling it to perform the designed working functions. Examples of own advanced research on several selected, newly developed materials, used in very different areas of application, confirmed the validity of the scientific hypothesis and the relationship between the studied phenomena and structural effects and the working functions of products and their maintenance and indicated that material design is one of the most important elements guaranteeing progress production at the stage of Industry 4.0 of the industrial revolution. Design/methodology/approach: The author's considerations are based on an extensive literature study and the results of the author's previous study and empirical work. Each of the examples given required the use of a full set of research methods available to modern material engineering, including HRTEM high-resolution transmission electron microscopy. Findings: The most interesting intellectual achievements contained in the paper include presentations of the author's original concepts regarding the augmentation of the Industry 4.0 model, which has been distributed so far, which not only requires augmentation but is actually only one of the 4 elements of the technology platform of the extended holistic model of current industrial development, concerning cyber-IT production aided system. The author also presents his own concept for designing material, maintenance and manufacturing 3MD already at the stage of material and technological design of the product, eliminating many problems related to product maintenance, even before they are manufactured and put into exploitation. Detailed results of detailed structural researches of several selected avant-garde engineering materials and discussion of structural changes that accompanying their manufacturing and/or processing are also included. Originality/value: The originality of the paper is associated with the novelty of the approach to analysing maintenance problems of materials and products, taking into account the requirements of the contemporary stage of Industry 4.0 development. The value of the paper is mainly associated with the presentation of original issues referred to as findings, including the concept of augmentation of the Industry 4.0 model and the introduction and experimental confirmation of the idea by designing material, maintenance and manufacturing 3MD.
