In the oscillating wear test under engine oil containing Mo-DTC (Molybdenum Dithio-Carbamate), friction coefficient and wear volume of cylinder-specimen were lower than without Mo-DTC, in contrast, DLC (Diamond-Like Carbon) film was worn deeply. A residue of oil contained amorphous carbon that had higher proportion of sp2 electron structure and lower density than DLC as coating. Judging by these results of our investigation, DLC film is graphitized in wear test under lubrication. This specific wear of DLC films is based on the wear mechanism that is attributed to graphitization, and the hard molybdenum sulfide and oxide which are decompositions of Mo-DTC are accelerated wear mechanically.

@cien_caras_cien スピードハートさんのヤマハ専用オイルはそれを前面に出してウリにしてますからね https://t.co/9SAXspNXhm
二硫化モリブデン系オイル添加剤を手に入れたので使ってみるかと思ったけど落とし穴が.DLCと相性が悪いらしい.最新高性能エンジンとは合わないようだ. Ref: https://t.co/rMl5Ns2QyI Ref: 杉本, "Mo-DTC含有オイル中におけるDLC固有の摩耗メカニズム", 2012, https://t.co/TeAHnT0Ti7
@kurouma007 これからの時代、DLCも今まで以上に多様に使われると思います エンジンオイルも相性がある時代になるかな?と考えてます https://t.co/upPOAJtMK8
