Production process of lost foam casting steel claw was modified including adopting top pouring and setting blind riser at interfacial position of two arms with claw of the steel claw, which not only simplifyied the complex milling process and increased product efficiency but also decreased product cost and enhanced economic profit and market competition. Meanwhile, the technology could meet the requirements of saveenergy and environmental protection for foundry trade. The practical production verifies the feasibility of the method.

In order to improve the corrosion resistance of magnesium alloy surface, taking the Al powder as laser cladding materials, laser cladding Al coating on the magnesium alloy surface was carried out, and the cladding layer with gas-free and crack-free as well as desirable metallurgical bonding with the matrix on the magnesium alloy surface could be generated. Meanwhile, effects of laser parameters on microstructure of the cladding coating were investigated.
