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.
