Improvement of the quality of TiC-Co system plasma coating by laser treatment

Abstract

The paper considers the possibility to improve the quality of a plasma coating by means of a laser treatment in the melting and thermal cycling modes. This method provides stronger adhesion of a coating to its base material as well as higher wear resistance. The regularities of the laser treatment in the melting and thermal cycling modes are determined, and a connection between the technological parameters and the quality characteristics is shown.
