sections. Firstly, the coatings were melted on the substrate. In this section, the fusion power was 2 kW and the scanning velocity was 300 mm/min, and the laser beam diameter was 3mm. Secondly, the coatings were re-melted while the laser power was 2.5 kW and the scanning velocity was 600 mm/min. At last, the values of laser power, laser beam diameter and scanning speed were 3.500-5.0 kW, 2 mm, and 3......
