| Abstract: | The abrasive wear performance of HVOF sprayed Cr 3C 2 NiCr coating deposited with three kinds of powders was experimented by a Rubber Wheel Abrasive Tester. The correlation between coating weight loss and sliding distance, the influence of spray parameters and powder fabrication process on the abrasive wear rate of the coatings were studied based on the experimental results. The abrasive wear behavior of this coating was detected on the analysis of the morphology features of coating structure and abrasive wear surface. |
