Paper Title:
Evaluation of Wear Behavior of Feldspar Particles Reinforced Copper Alloy Composite Materials
  Abstract

The wear behavior of unreinforced as well as feldspar particles reinforced copper alloy (phosphor-bronze) composites was studied as a function of sliding speed and applied loads under unlubricated conditions. The content of feldspar particles in the composites was varied from 1- 5% by weight in steps of 2%. A pin-on-disc wear tester was used to evaluate the wear rate. Loads of 20-160 N in steps of 20 N and speeds of 1.25, 1.56, and 1.87 m/s were employed. The results indicated that the wear rate of both the composites and the alloy increased with increase in load and sliding speed. However, the composites exhibited lower wear rate than the alloy. It was found that above a critical applied load, there exists a transition from mild to severe wear both in the unreinforced alloy and in the composites. But the transition loads for the composites were much higher than that of the alloy. The transition loads increase with the increase in weight % of feldspar particles, but decreases with the increase in sliding speeds.
