Research on microstructure and properties of 3D plasma spray welding repair layer of continuous casting segmented rollers

Yuxiang Li,
Ying Zhou,
Zhengbing Meng
et al.

Abstract: In this paper, the Fe-Cr-Ni-Si powder was used in a 3D plasma spray welding machine to perform spray welding repair tests on continuous casting segmented rollers for service life improvement. The phase composition, hardness distribution, abrasion resistance and thermal stability of the spray welding layer were analyzed. Results indicated that the spray welding layer produced by 160 A welding current was more uniform and was with finer organization. The main phase zone was a single γ-Fe and the fusion zone was … Show more
