Experimental Research on 32Cr3MolV Substrate Anti-Molten Aluminum Corrosion by Laser Treatment
Two types of layers were prepared by means of laser surface alloying process using High-power Transverse Flow CO2 laser beam with different additions, which were pure Cr powder and Co alloy powder on the 32Cr3MolV substrate. The unique characters of laser treatments, such as microstructure, distribution of elements, and micro-hardness were studies in thorough; furthermore, the abilities anti-molten aluminums corroding of the layers were tested in 700 centigrade molten aluminum. The results indicate that both laser treated layers can enforce the ability anti-corroding of the molten aluminum on 32Cr3Mol V substrate, while the laser alloying layer with Cr powder shows the most advantage of anti-aluminum corrosion character, i.e. the layer does not be corroded at all in the corrosion experiment. And the diffused thickness of aluminum in the layers by laser alloying process with Co powder is half below that of in the 32Cr3MolV substrate.
