The abrasive wear behavior of high velocity oxy-fuel (HVOF) sprayed Cr3C2-25%NiCr coatings deposited in different conditions was investigated by wet sand rubber wheel abrasive wear tester using three kinds of abrasives (brown alumina, Jin Gang sand and Hu Kou sand). The abrasive wear mechanism was discussed. The results show that weight loss of HVOF sprayed Cr3C2-25% NiCr coating after worn with three kinds of sand is different. The weight loss of the coating after worn with alumina sand is the… CONTINUE READING
