DEVELOPING ENDURANCE OF SLIDING SURFACES BY TUNGSTEN CARBIDE INTRODUCTION

The influence of the implanted tungsten carbides on the formation in the sliding surfaces of the enduring structures, which are developed during implementation of the combined electromechanical processing technology, is investigated. It is shown that the intensive solution trial of steel with dissolution of tungsten carbide powder and the subsequent formation of composite nanostructures as a result of fission of undercooled austenite supersaturated by tungstenproceeds at thermal power impact in the deformation zone. The results of triboengineering testings of cylindrical samples by the normalized method are given.
