英文摘要	The self-sensing tribological composite coating (Cu-14Al-X/SrAl2O4:Eu2+, Dy3+) for wear indicator is quenched because of vacuum pressure-assisted sintering method, which do harm to the monitoring of coating. In this paper, we constructed a model to explain the quenching mechanism of SrAl2O4:Eu2+, Dy3+ in alloy coatings. The initial electron concentration and the energy level structures were studied. The results show that contact quenching rather than the traditional thermal quenching is the most important influencing factor for SrAl2O4:Eu2+, Dy3+. The contact metal in coatings can be as a defect level and dissipation center of electron transition, the quenching process could be well explained by the model we proposed.
