Abstract
The evolution and distribution of temperature have been studied theoretically for an idealized model of a four-ball wear-test apparatus which can be used to study macroscopic effects of surfaces interacting under frictional conditions. The finite-difference method was used to solve the coupled equations of heat generation, conduction, and cooling. Parameters were chosen to represent two types of material, a typical steel with relatively good thermal conductivity, and a ceramic with relatively poor thermal conductivity. Two values for the coefficients of friction were used to simulate dry and lubricated surfaces. A significant dependence on thermal conductivity was found.This publication has 7 references indexed in Scilit:
