Abstract

With scanning speeding of 20 ∼ 200 m/min, extreme high-speed laser cladding is a high-efficiency choice to fabricate thin protective coatings with thickness of 0.01 ∼ 0.25 mm on metal parts. Laser remelting is considered as an effective strategy to improve surface characteristics. In the present paper, mirco-scale Fe82Cr16SiB alloy single-layer coatings are successfully prepared on H13 steel substrate by above integrated process with slow scanning speed below 5 m/min. The flatness of the defect-free coatings is substantially improved with the formation of a refined gradient microstructure along the growth direction. The remelted coating exhibits enhanced corrosion resistance, higher hardness, good wear resistance with lower friction coefficient.
