Abstract
Promotion mechanism of wear and formation of tribofilm on DLC by Molybdenum based lubricant additives has not been sufficiently revealed. Therefore, we conducted friction and wear test with DLC, FC250 and Molybdenum based lubricant additives and observing and analysing sliding surface of specimens. As a result, the promotion mechanism of wear for the DLC was different by type of Molybdenum additives and it was difficult to form deposits on surface of DLC by Molybdenum additives. Moreover, it was found that hydrogen content in DLC is not main factor of promotion mechanism of wear by Molybdenum based lubricant additives.
