Evaluating Tribological Behavior of Ti3SiC2 Ternary Compound for Use as Solid Lubricant

In this research, the lubricity behavior of Ti3SiC2 was investigated by using a pin-on-disc a sliding wear test with a AISI 52100 steel. In the pin-on-disc test, samples show the low friction coefficient (µ), especially in low loads. Microscopic observations show a lubricating layer on samples surfaces that the result of decreasing of µ due to the lubricating behavior. In a high load, samples shows increase in µ (≈ 200N) and wear rate in 80 N loads, approximately. This behavior explains the stability of abrasion mechanism by increasing the force. The results showed that Ti3SiC2 as a lubricity behavior in low loads (< 80 N) and can be used as a solid lubricant.
