Microstructure and Erosion Resistance of Hot-Dip-Aluminized 3Cr13 Steel

Abstract:

Fe-Al intermetallic coating was prepared on 3Cr13 steel by hot-dip aluminizing and diffusion process. The morphology and phase of the coating were analyzed; the erosion behavior of hot-dip-aluminized 3Cr13 steel was investigated. Results showed that the thickness of the coating increased with diffusion temperature, but decreased when diffusion temperature exceeded 800°C. The Fe-Al alloy layer diffused at 900°C presented compacted microstructure, and mainly contained FeAl and a few Fe₃Al. Fe-Al intermetallic coating possessed obviously declined erosion loss compared with unaluminized 3Cr13 steel and represented typical erosion characteristics of ductile material.
