| Abstract: | This paper deals with the structure, the corrosion resistance of chromium alloying layer of steel No. 45 by a 2kW CO2 continual laser beam and the effect of laser beam travel speed on the depth, width, chromimum content, hardness and surface roughness of alloying layer. It is shown that for a given beam diameter, the depth and width of alloying layer decreases with an increase of laser beam travel speed and the chromium content of alloying layer increases with an increase of laser beam travel speed. However, there is a maxium on the curve for the relationship between laser beam travel speed and roughness of alloying surface. The resistance to corrosion of steel No.45 can be markedly improved by such alloying. |
