Microstructure and Wearability of Surface Coating of Fe-Based Amorphous Core Welding Rod

Abstract:

Article Preview

Based on the classic formula of J507 coated electrode,the welding rods were prepared by adding Fe41Co7Cr15Mo14C15B6Y2 Fe-based amorphous alloy or HO8A as welding core. The surface coating on Q235 was made by manual electric arc welding with two kinds of welding rods,while Ar2 gas is used to cool the weld layer. The microstructure and wearability of welded joint and the coating layer were investigated by the means of metallographic analysis, SEM,XRD and M-2000 wear tester.The results show that the coating layer is in the amorphous state,and the wearability of surface coating with Fe-based amorphous core welding rod is better than another.
