A STUDY OF IRON BASED METAL-PLASTICS AND THEIR FRICTION AND WEAR BEHAVIORS

Metal-Plasties is a new type of antifriction materials developed on the basis of powder metallurgy in recent years. This paper describes the processing of these iron based metal-plastics and studies the influence of carbon amount on mechanical properties of the matrix and the friction and wear behaviors under the conditions of different load. The results obtained indicate that these materials Possess high mechanical strength and good friction and wear rcsistance. When load is in a range of 0-25kg,the friction and wear properties of the materials come up to that of DU material. Running test results also show that the service life of the material is more than twice as longe as that of iron based self-lubricating bealing.
