 The effects of organic friction modifier; GMO and PLA/HEA on lubricity of MoDTC were investigated using a reciprocating-type tribotester and several surface analyses. From the results of friction tests, the lubrication with PAO (poly-alpha olefin) + MoDTC + PLA/HEA exhibited lower friction coefficient than the lubrication with PAO + MoDTC, whereas the lubrication with PAO + MoDTC + GMO exhibited higher friction coefficient than the lubrication with PAO + MoDTC. The surface analysis results indicate that GMO inhibited the formation of MoS2 tribofilms on the sliding surface.
