Wear Behavior of Plasma Processed LM6 Alloy

Abstract:

In the current work, wear behavior of plasma processed LM6 alloy is investigated. LM6 alloy was prepared by plasma technique. The samples were aged at 350^°C & 450^°C for 2 hours followed by water quenching. A comparative study of the metallographic structure and properties viz. hardness, density and wear of the non-heat and heat treated alloy samples were carried out. A very fine lamellar structure is observed in case of 450^°C heat treated samples than that of sample heat treated at 350^°C and non-heat treated samples. Highest hardness value of 68.11 VHN is observed with the sample heat treated at 450^°C. Density is found to be the lowest in non-heat treated samples and it increases with increasing heat treatment temperature. Wear experiments were carried on a pin-on-disc set up (of Ducom make), varying applied loads (between 10-40Newton and varying sliding speed (from 0.94 m. s^-1 to 2. 83m.s^-1⁾. Maximum wear resistance is observed with the specimen heat treated at 450^°C.
