Temperature distribution in surface layers of rubbing solids

Abstract

The aim of the study is to propose a modified method of determining temperature distribution in thin surface layers of friction members and obtain data on the temperature, its gradient and distribution in depth of the layers. The optical-electron scanning technique was used to study temperature distribution in depth of rubbing bodies. The material of surface layers is shown to undergo severe thermal loading (the temperature gradient along the normal to the interface reaches 104 K/mm). Three kinds of temperature distribution in depth of the material have been registered and the existence of a subsurface heat source has been proved.
