- •
Maximum scanning speed can be increased to 1500 mm/min in Ni-based 50% WC coating by LIHC.
- •
Maximum powder feeding rate can be increased to 65.3 g/min in Ni-based 50% WC coating by LIHC.
- •
Most of WC particles dissolved and carbides with different shapes were precipitated during LC.
- •
Herringbone carbides precipitated and incompletely dissolved WC distributed at the side of coating by LIHC.
- •
Wear resistance of LIHC coating was 1.4 times higher than that of LC coating when laser scanning speed was 1500 mm/min.
