Tribotechnical characteristics of cast iron with a steel coating in lubrication medium under unsteady modes

摘要

The effect of the lubrication, antifriction, and rheological characteristics of transmission oil exerted on the wear resistance of a sprayed 30KhGSA steel coating on cast iron under the conditions of a stepwise load increase has been studied. An increase in serviceability with increasing thickness of the coating due to the formation of screening boundary lubricating layers characterized by low shear stress and the stabilization of the specific frictional work in the contact area has been revealed.
