Abstract
Effects of the action of low-energy high-current electron beam pulses of microsecond duration on microstructure and tribological properties of 'WC-30% Hadfield steel' hard alloy in the friction pair with tool steel have been studied. It was established that pulsed melting and following high-speed quenching of the surface layers result in reducing the grain size of both initial carbide and binding phases as well as in formation of metastable M12C and M23C6 carbides. The microstructure changes lead to increase of the surface microhardness by a factor of 1.5, decrease of the friction coefficient by a factor of 2, and wear resistance enhancement as compared to the material in initial condition.
