AI Technical Summary
Existing stainless steel magnesium reduction tanks are susceptible to oxidation and corrosion under high-temperature conditions, resulting in a short service life. Furthermore, the inner wall is easily corroded by magnesium slag, causing slag adhesion and deformation, which affects the performance.
A corrosion-resistant laser cladding layer is prepared on the inner wall of a magnesium reduction vessel. The ceramic layer, transition layer and alloy magnesium-carbon layer are formed by laser cladding of composite ceramic powder, boride powder and alloy powder, which enhances the bonding strength and resistance to magnesium slag corrosion.
It improves the corrosion resistance and service life of magnesium reduction tank, reduces the amount of slag cleaning work on the inner wall, ensures the high strength and high bonding stability of the alloy magnesium reduction tank, and reduces the impact of thermal stress.
