Study on Tribological Performance of Al₂O₃ Particle Reinforced the Al-Sn Bearing Alloy

Abstract:

In order to improve performance of Al-Sn bearing alloys, a new Al₂O₃/Al-Sn composite was fabricated through in-situ reaction between Al and SiO₂. A study has been conducted to investigate tribological performance of the composite on MMW-1 Computer controlled vertical universal friction and wear testing machine. The results show that Al₂O₃ and Si particles are mainly distributed in the grain boundary and particles are often coated by a thin Sn layer. Friction coefficient of Al₂O₃/Al-Sn composites is decreased with Sn additions up to 21wt. %.
