Abstract and keywords

Abstract (English):
A method to improve the properties of aluminum alloys by laser surface alloying is considered. The optimal selection of alloying elements is carried out. It is shown that this method of hardening increases the wear resistance and reduces the friction ratio of the hardened surface.

Keywords:
