Summary:It is important for the machine components to have a good wear resistance for the material surfaces In order to improve wear resistance for these elements can be used laser techniques. In the paper are presented laser techniques using powders. It is possible to make a heat treatment with laser to improve the wear resistance or it is possible to use a laser alloying techniques. In the paper are presented both methods. Are analyzed the heat treatment with laser on the metallic material C50 and laser alloying techniques using carbide powders, both methods in order to obtain a laser processed layers with high wear resistance of the superficial layers. The effect parameter variation of the laser beam is investigated in the papers using optic microscope, electronic microscope (SEM) and wear resistant test with Timken tribometer. On the superficial layers are measured also the layers thickness and microhardness. Key words: laser, wear resistance, heat treatment, superficial layers, microhardness
