Notes:
Sliding experiments lubricated with hydroxyl silicate magnesium particles as additivewere performed under ambient condition and different loads by using an AMSLER friction andwear tester. The surface topographies and compositions of worn surface of 45 steel rings wereanalyzed by SEM and EDAX. The experimental results show that the friction load had great effecton generation of the frictionally-formed protective coating. No protective coating formed on theworn steel surface under lower friction load. However, a smooth and continuous protective coatingcan be developed on the worn surface of the steel when the friction load is high enough. Thechemical composition of the protective coating is roughly the same as the additive. The additive canbe fractured, stretched and flowed along the sliding direction under high contacting stress andinstantaneous flash temperature, which result in coating being formed
