Abstract <p>Tribological studies of 5KhNM, 11Kh4V2MF3S2, and 95Kh6M3F3ST steels have been performed under dry sliding friction conditions in pairs of a steel disk–TT10K8B hard alloy pin at a pressure of 40 MPa. The test scheme has been based on the reciprocating movement of a steel sample relative to a carbide counterbody at a speed of 0.1 m/s. The test time for each sample was 10 h. The value of linear wear of friction pair elements has been used as a resistance criterion in the process of sliding friction. Minimal wear under dry sliding friction conditions in a pair with a TT10K8B hard alloy indenter has been recorded when testing samples of 11Kh4V2MF3S2 high-carbon tool steel after hardening from 1060°C and three-fold tempering at 525°C. The value of the total linear wear in the friction pair 11Kh4V2MF3S2 steel–TT10K8B hard alloy is four times less compared to that of the pair 5KhNM steel–TT10K8B hard alloy.</p>

Abstract

Tribological studies of 5KhNM, 11Kh4V2MF3S2, and 95Kh6M3F3ST steels have been performed under dry sliding friction conditions in pairs of a steel disk–TT10K8B hard alloy pin at a pressure of 40 MPa. The test scheme has been based on the reciprocating movement of a steel sample relative to a carbide counterbody at a speed of 0.1 m/s. The test time for each sample was 10 h. The value of linear wear of friction pair elements has been used as a resistance criterion in the process of sliding friction. Minimal wear under dry sliding friction conditions in a pair with a TT10K8B hard alloy indenter has been recorded when testing samples of 11Kh4V2MF3S2 high-carbon tool steel after hardening from 1060°C and three-fold tempering at 525°C. The value of the total linear wear in the friction pair 11Kh4V2MF3S2 steel–TT10K8B hard alloy is four times less compared to that of the pair 5KhNM steel–TT10K8B hard alloy.
