Comparative investigations were made of the contact life of 00N18KM5T and 00N14Kh5M3T maraging steels and 38KhN3MFA dispersion-hardened steel with different variations of melting and heat and chemicothermal treatment. The contact life investigations were made in the 450-2000-MPa range of stresses with a degree of slippage of 5%. It was established that regardless of the chemical composition and heat treatment, nitriding by ionized nitrogen in the plasma of a glow discharge provides the greatest increase in specimen contact life (210-245%).
