SHS-TiC Particle Reinforced Hardface Coating Prepared by Vacuum Cladding Process

Abstract:

A particle reinforced hardface coating was prepared by vacuum cladding process. Firstly, titanium carbide composite powders were prepared by self-propagating high-temperature synthesis (SHS). The hardface coating was then formed on plain carbon steel substrate with the TiC composite powders and high chromium iron-based alloy powders by vacuum sintering. The microstructure of the coating was observed and then the wear resistance was studied. The results show that TiC composite particles uniformly distribute in the coating. The coating and the steel substrate are chemical bonded with each other. When the size of TiC particles is unchanged, with the increase of quality fraction of the TiC particles, the hardness increased gradually and the wear resistance of composite coating under different conditions changed. The unit area weigh loss increased following by the load increasing, and the unit area weigh loss is the most under Alkaline condition. And the unit area weight loss increased following by the increase of the abrasive and the reaction time.
