The main process parameters affecting the formation of the sur face layer quality were identified. Studies of the process were carried out in order to obtain dependencies for calculating the roughness of the surface, the depth of the strengthened layer, the degree of plastic deformation, residual stresses, processing time and their experimental confirmation. he discrepancy between the results of theoretical and experimental studies does not exceed 20 %, which indicates their high convergence. Technological recommendations are given for designing the technological process of processing with a ball-rod hardener in the conditions of digital production. A methodology for computer-aided design of technological processes using the Microsoft Visual Studio software development environment in the C# programming language has been developed and presented.

The coatings were obtained by pulsed laser deposition from a MoSe2 target, which ensured the formation of a nanocomposite structure consisting of an amorphous matrix and Mo nanoparticles. To dope the coatings with sulfur atoms, the MoSe2 target was ablated in H2S gas of varying pressure. It has been established that optimization of the reactive gas pressure is required to improve the tribological properties of the MoSex /Mo coatings. When sulfur atoms are introduced up to a concentration of 7...14 at. %, a significant increase in the wear resistance of the coatings was observed both during tribological tests in air and in nitrogen. In this case, a notice able effect was achieved in reducing the coefficient of friction. As a result of alloying with sulfur, the friction coefficient in air decreased to 0.035, and in nitrogen to 0.015. The results of the study of wear tracks and wear debris by micro-Raman spectroscopy are presented, which made it possible to reveal the features of tribo-induced processes in the created coatings.","PeriodicalId":178558,"journal":{"name":"Strengthening Technologies and Coatings","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123660343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
