Sliding-wear characteristics of WC-12Co HVOF thermal spraying coatings
WC-12 Co coatings were prepared on copper matrix composites by high velocity oxygen-fuel flame(HVOF) thermal spraying. Their microstructure,surface and cross-section hardness,composition and content of phases,and tribological behavior were studied. The results show that the coatings appear uniform m...

| description | WC-12 Co coatings were prepared on copper matrix composites by high velocity oxygen-fuel flame(HVOF) thermal spraying. Their microstructure,surface and cross-section hardness,composition and content of phases,and tribological behavior were studied. The results show that the coatings appear uniform microstructure and high hardness. During the wear,two kinds of tribofilms form. The most suitable condition for the coatings is 300-500 r·min-1 and 2-3 N. The wear rate increases with increasing load. While the rotating speed increases,the wear rate presents a trend of first decreasing and then increasing. The fitting equations between wear rate and sliding speed and between wear rate and normal load are quadratic and exponential,respectively. |
