The sliding friction and wear behavior of aluminum manganese based composite materials

aluminum manganese alloy and pure aluminum were measured through using the M-2000 type tester with or without corrosion liquid

respectively

and their surface morphology was observed by LED 1430 VP type scanning electron microscopy.The results show that the cutting wear is predominant in the materials with the corrosive liquid while adhesion wear is dominant in the matirials without corrosion liquid

and the wear loss of the different materials is as follows:Al-Mn composites less than Al-Mn alloy less than pure aluminum.With the same Mn content

the wear resistance of the Al-Mn composites is obviously superior to that of Al-Mn alloy.
