. To further improve the surface properties, the HVOF coating was heat-treated by a CO2 laser. The surface properties of … both the coating and the laser-heated coating were then compared. The HVOF optimal coating process (OCP) for a coating with … the highest surface hardness was determined with the Taguchi program. The friction and wear behaviors of the coating, an …

TiC-based wear resistant coating was prepared by plasma spraying using reconstituted composite powders doped with ultra …-fine carbide. Phase composition and microstructure of as-sprayed coating were characterized by X-ray diffraction (XRD), scanning … performed by using a ring-on-block tester under dry sliding condition. Results show that the coating adheres well to the …
