Tribo-oxidation

WebSep 1, 2010 · INTRODUCTION. On the surface of a catalyst, the chemisorbed gas reacts with another kind of chemisorbed gas. The authors have found that this gas-gas reaction was enhanced by friction and called it “friction catalysis” or “tribo-catalysis” (Hiratsuka, et al. (Citation 1), (Citation 2)).For example, the synthesis reactions listed below were enhanced … WebThe Tribo-Potential wear tests (TP) indicated a reduction in coefficient of friction as load increases with poor film adhesion compared to Tribo-wear tests (T); this effect has resulted from an oxidation wear mechanism that has dominated the surface of the magnesium alloy.
