【 摘 要 】
In this study researches were carried out about the impact of pulsed laser irradiation on the surface of M2 steel which had been surfaced beforehand on steel 20 by poweder-pasma surfacing technique. The surface treatment was performed by the single point laser action and by successive imposition of overlapped impulses. During the surfacing the average irradiation power was varied from 15.8 to 21.0 W. The impulse duration in all points was constant and it was 7 msec. In this study it was researched the influence of laser-beam power change on the depth of penetration, changes in the structure and microhardness of treated areas.【 预 览 】
