Effect of laser treatment on the wear resistance of steels

It is known that laser hardening increases the wear resistance of friction parts quite substantially. At the same time, many problems connected with t he effect of the treatment process and the special features of laser harden ing on the characteristics of wear resistance require detailed consideratio n. The present paper is devoted to the development of recommendations on ch oosing the optimum location and proportion of the areas of the hardened and unhardened regions of the surface of structural steels after their treatme nt with radiation of a continuous CO2 laser.
