| Abstract: | This paper deals with the forming of laser-treated surface chromium alloying layer on steel No. 45 and the influence of technological parameters and the thicknsss of chromium powder coating on the depth of and chromium content in the surface alloying layer. The electrochemical property and corroslon resistance of the alloying layer are comopared with those of steel No. 45 and of steel 1Cr18Ni9Ti. Tho relation between the structure of ,the alloying layer and corrosion resistance is discussed. Itis shown that the influence of thickness of chromium powder coating on the depth of the alloying layer is less significant than that of the travel speed of laser beamand a chromium content of 14-23% can be obtained in the alloying layer for suitabletechnological parameters. Laser-treated chromium alloying is an effective method for improving the corrosion resistance of ordinary carbon steels. |
