Optimization of spark alloying operating parameters of tribosystem partsAllerton Press - Tập 30 - Trang 106-109 - 2009
D. N. Korotaev, Yu. K. Mashkov
The paper presents the results of optimized studies of the processing parameters of steel surfaces by electro-spark alloying. It is shown that with increasing capacitor capacitance with simultaneous voltage reduction between the alloying electrode and the surface treated, the adhesive constituent of the friction force decreases. A relationship is found between the alloying energy parameters and th...... hiện toàn bộ
Ways of improving the tribological properties of steel gas-flame coatingsAllerton Press - Tập 32 - Trang 395-403 - 2011

The paper reports the results of study of the structure and properties of steel gas-flame coatings. The effect of the formation of an abnormally great amount of retained austenite during the deposition of coatings from steel wire is found. Techniques for implementing the “austenite effect” to improve the wear resistance of the coatings are proposed. A method for introducing a solid lubricant into ...... hiện toàn bộ
Calculating the Contact Approach in a Cylinder upon ReindentationAllerton Press - Tập 40 - Trang 569-572 - 2020

The paper discusses the regularities of the contact approach upon reindentation of an elastic cylinder into the flat surface of a part and its elastic–plastic deformation. It is shown that the value of the elastic approach upon repeat loading coincides with the elastic approach for the first loading.
The problem of mathematical simulation of rolling frictionAllerton Press - Tập 30 - Trang 305-308 - 2009
V. I. Bakhshaliev
The process of friction of a cylinder (roller) rolling over a cylindrical surface (bearing) is studied; the hypothesis is advanced that the local slip of elements of the roller surface can be replaced with relative microdisplacements of these components within the local plastic compression area. The equation of the profile of local plastic compression of the contact surface between the roller and ...... hiện toàn bộ
Properties of coatings based on Cr, Ti, and Mo nitrides with embedded metals deposited on cutting toolsAllerton Press - Tập 32 - Trang 192-198 - 2011
A. K. Kuleshov, V. V. Uglov, V. V. Chayevski, V. M. Anishchik
The relation between the phase-structure state and mechanical and operating characteristics of coatings based on solid solutions of (Ti, Cr)N, (Ti, Mo)N with Cr and Mo formed on a hard tool T15K6 alloy by condensation and ion bombardment of combined plasma flows in nitrogen is studied. A tool with the coating based on the solid solution (Ti, Cr)N is shown to have high hardness, low friction coeffi...... hiện toàn bộ
Wear Resistance of Amorphous-Crystalline Coatings with LubricantsAllerton Press - Tập 39 - Trang 38-43 - 2018
V. P. Babak, V. V. Shchepetov
The results of tests of a Zr–Al–B boundary friction detonation coating in a wide range of changes under friction conditions have been presented. A comparative analysis of the obtained characteristics of friction and wear in order to evaluate the tribotechnical properties of amorphous-crystalline coatings has been carried out. These results have been compared with parallel tests of coatings based o...... hiện toàn bộ
Influence of nanosized carbon additives on the structure formation and tribological behavior of galvanic chrome coatingsAllerton Press - Tập 30 - Trang 94-100 - 2009
P. A. Vityaz’, V. I. Zhornik, R. G. Shtemplyuk, S. A. Kovaleva
The paper discusses the features of the structure formation of electrochemical chrome coatings on the introduction into the electrolyte composition of a disperse phase in the form of nanosized carbon additives (ultradispersed diamonds of denotation synthesis and diamond-graphite charge). It is shown that nanosized carbon additives encourage the formation of more dense coatings having fine-crystall...... hiện toàn bộ
