Structure‐energy criterion of the wear resistance of metals and alloys with allowance for the stiffness of the stressed‐strained state of the surface

Abstract

Purpose

The purpose of this paper is to analyse the phenomenon of wear resistance of some metals and alloys with allowance for the stiffness of their stressed‐strained state of the surface.

Design/methodology/approach

An original criterion (in the form of limiting deformation power density) of wear resistance on the basis of structure‐energy theory of friction is proposed. Experimental data on the wear resistance are generalized using the criterion for the conditions of hydroabrasive, impact‐abrasive and cavitational erosion.

Findings

The dependence of the criterion on stiffness coefficient of the stressed‐strained state of the surface of materials is demonstrated. It has been found that an increase of the stiffness results in the reduction in the energy capacity and wear resistance of both metals and alloys investigated.

Practical implications

The structure‐energy criterion can be used for choosing suitable frictional materials and to compare and estimate the theoretical considerations with experimental data.

Originality/value

The proposed structure‐energy approach allows systemizing the results of our analyses and the experimental data.
