Abstract
Method of changing the quality characteristics of surface layers produced by a laser surfacing or strengthening treatment is suggested. The feasibility of control of the cooling processes of the deposited layers by changing the space distribution of radiation power in the focusing plane is shown. Unique technical solutions were used for control of the space distribution of the laser radiation power.
Keywords: laser beam, laser surfacing, space distribution of power, focusing systems, cooling rate, heat source, residual stresses, cracks in surfacing
