中文摘要	The present hardening technologies for corrugated rollers, such as intermediate frequency quenching, nitrogen hardening, chromeplate, laser transformation hardening and tungsten carbide spraying, have some limitation on cost, lifetime, technique stability and rejuvenation capability. Laser cladding offers an approach to improve the above comprehensive properties when hardfacing and repairing the corrugated rollers. This paper reported a laser cladded particulate reinforced composite coating by using a unique cladding powder material THW-64 to tackle the severe dry friction abrasive wear on corrugated roller surface. After laser cladding with optimized parameters, the crack-free coatings with thickness over 0.4 mm, have strong metallurgie bond with the substrate. The main microstructure of the coating consists of hypoeutectic matrix and many homogeneously distributed complex carbide particles with average hardness of 915HV/sub 0.2/. Wear test and real production applications demonstrate that the abrasive wear resistance and working lifetime of corrugated rollers hardfaced by these particulate-reinforced composite coatings have been dramatically improved.
