Abstract

In this paper, the authors attempt to select the technological parameters of laser padding of spring steel. The coating material was prepared in the form of Al2O3 powder paste. Laser coated specimens were subjected to tribological tests of abrasion resistance, hardness, microstructure and elements distribution in the coating. The conducted tests indicate that the technology of laser padding with powder paste is feasible. Obtaining a coating with interesting properties depends on the selection of laser processing parameters.
