An Application of Antifriction Coatings to Increase the Lifetime of Friction Units

Abstract

This article presents a generalization of the results of theoretical and experimental studies on increasing the reliability of friction units by making antifriction coatings on the working surfaces with a flexible tool. The principle scheme and the essence of the method of cladding with a flexible tool (CFT) - shock-frictional forming of thin films from various materials on the surface of the workpiece with flexible elements of rotating metal brushes are described. Versions of cladding machinery and many parts of movable joints with various forms of friction surfaces, on which various metal, polymer, single and two-layer antifriction coatings are applied, are presented. The modification of the frictional application of polymer coatings is shown. The following is a brief description of the most significant effective results for increasing the durability of the industrial sliding friction and rolling friction units.
