Abstract

Laser radiation action on the surface of metals allows modification of material surface layer properties. One of the latest methods of such a treatment is the laser doping of the surface layer of metals with foreign atoms. Depending on the selection of the doping material as well as on the selection of the treatment parameters one can affect changes in certain properties of the surface layer of the material under treatment (micro hardness, resistance to abrasion and corrosion, electrical properties and others). In the article a study has been presented of changes in the laser doped surface layer of conducting materials used, among other things, for electric contacts. A comparative analysis of the resistivity of based materials (W, Ag, Ni) prior to treatment has been carried out. The optimization of doping conditions from the viewpoint of obtaining lasers of set parameters has been made.
