Study on Microstructure and Tribological Properties of Plasma Processed LM6 Alloy

In the research work, LM6 alloy prepared by plasma processed technique is studied for wear behavior. The wear behavior of the plasma processed LM6 alloy sample is study at room conditions at four different loads,i.e. 10N, 20N, 30N, 40N and with different sliding speeds, i.e. 200, 300, 400, 600 rpm’s for about 2 min,5 min,10min,15 min respectively, using a pin-on-disk wear testing instrument. From the pin-on-disk experiment, cumulative mass loss varying with the sliding speed, applied load and time was studied. The existence of eutectic silicon is sensed by the microstructure. The wear of plasma processed LM6 alloy sample increased as applied load, sliding speed and time increased.
