Description
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
