Fretting Tribology of Cu Matrix Composite Reinforced by In Situ Al2O3 Particle
Combined SHS with casting, in-situ Al2O3 particle-reinforced copper matrix composite was fabricated. The effects of the load and Al2O3 particle on the friction coefficient and wear volume were investigated. And the wear resistance of composite was compared with that of pure copper. The results show that with the increase of load, the coefficient of the copper increases, while it decreases slightly as to composite. The wear volume of the composite is always lower than that of copper. The highest relative wear ability is 4.5, which indicates a better wear resistance..
