The article gives results of research of the process of
abrasive wear of samples made of Steel 45, U10 and
with applied composite surface layer "nickelmulticomponent
material with shape memory effect
(SME) based on TiNi". For the tests we have chosen
TiNiZr, which is in the martensite state and
TiNiHfCu, which is in the austenitic state at the test
temperature. The formation of the surface layer was
carried out by high-speed gas-flame deposition in a
protective atmosphere of argon. In the wear test,
Al2O3 corundum powder was used as an abrasive. It is
shown that the wear rate of samples with a composite
surface layer of multicomponent materials with an
SME is significantly reduced in comparison with the
base, which is explained by reversible phase
transformations of the surface layer with an SME.
After carrying out the additional surface plastic
deformation operation (SPD), the resistance of the
laminated composition to abrasion wear is greatly
enhanced, due to the reinforcing effect of the SPD. It
is recommended for products working in conditions of
abrasive wear and high temperatures to use the
complex technology of formation of the surface
composition "steel-nickel-material with high-temperature EPF", including preparation of the surface
of the substrate and the deposited material, VGN in
the protective atmosphere of argon, followed by SPD
