Optimization of spark alloying operating parameters of tribosystem parts
Allerton Press - Tập 30 - Trang 106-109 - 2009
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...
Ways of improving the tribological properties of steel gas-flame coatings
Allerton 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 ...
Calculating the Contact Approach in a Cylinder upon Reindentation
Allerton 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 friction
Allerton Press - Tập 30 - Trang 305-308 - 2009
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 ...
Wear resistance of composites for sliding electrical contact from reprocessed bearing steel
Allerton Press - - 2007
Antifrictional composites based on chemically modified UHMWPE. Part 2. The effect of nanofillers on the mechanical and triboengineering properties of chemically modified UHMWPE
Allerton Press - Tập 32 - Trang 269-275 - 2011
The mechanical and tribological properties of nanocomposites based on chemically
modified ultra-high molecular weight polyethylene are determined. The
super-molecular and chemical structure of the nanocomposites based on the block
copolymers UHMWPE-grafted UHMWPE and UHMWPE-grafted HDPE are studied by the
methods of X-ray structural analysis, IR spectroscopy, scanning differential
calorimetry, and...
Properties of coatings based on Cr, Ti, and Mo nitrides with embedded metals deposited on cutting tools
Allerton Press - Tập 32 - Trang 192-198 - 2011
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...
Computer Simulation of Accelerated Modes for Faster Testing of Friction Pairs Having Solid Lubricant Coatings

Wear Resistance of Amorphous-Crystalline Coatings with Lubricants
Allerton Press - Tập 39 - Trang 38-43 - 2018
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...
Influence of nanosized carbon additives on the structure formation and tribological behavior of galvanic chrome coatings
Allerton Press - Tập 30 - Trang 94-100 - 2009
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...
