Fretting Wear of a Sealing Gasket in a Flanged Joint
摘要
Abstract
The influence of the roughness of a steel surface on the slipping friction coefficient and wear of a sealing gasket in a flanged joint is studied. The dependence of the frictional coefficient on the surface roughness Ra of the steel part and the applied force is established. The critical tangential stress for the flange–gasket assembly is determined: at the critical stress, the surface layer of the sealing gasket fails, and sealing of the joint is lost.
