Abstract: A series of metal matrix composites of different proportion composed of PA66,PPS,Mn65 were prepared. The tribological properties test were carried out in different condition. Bonding strength test was carried out. The tribological properties test indicate that the friction coefficient and wear rate will be reduced with the increase of nylon66. The friction coefficient and wear rate of same materials increases first and then decreased with time and speed increased. The bonding strength test indicate that the bonding strength of metal matrix composites will be gradually increase with the increase of PPS.

Key words: metal matrix composites, tribological properties, bonding strength, poly(phenylene sulphide), polyamide 66
