Popis:	This review provides an assessment of the influence of the parameters of the laser hardening mode on the quality of the surface and the surface layer. It is presented how the processing speed, radiation power, surface heating temperature, initial structure during, the number of passes laser hardening affect the geometric parameters of the laser exposure zone, roughness, hardness and wear resistance of the surface, deformation, magnitude and sign of residual stresses in the surface layer. The conclusion is made in the form of recommendations on the selection of parameters of the laser hardening mode to obtain a given surface quality and surface layer of machine parts.
