主　　题：Copper-aluminium alloy coatings Luminescent powders Wear indicator Luminescent spectroscopy Tribology 

摘      要：Monitoring of coating health was achieved by embedding sensor materials(MAl_(2)O_(4):Eu^(2+),Dy^(3+),M=Sr,Ba)in tribological *** the luminescence disappears under ultraviolet(UV)light,it means that the functional coating is worn out and that recoating is *** this work,four types of alloy(Cu-14Al-X,Cu,Cu-Al,Al)composite coatings were investigated by vacuum pres sure-as sis ted sintering *** composite coatings with different copper-aluminium alloy matrixes were compared by phase composition,microstructure,luminescence properties and tribological *** results indicate that the Cu-14Al-X matrix composite coating shows not only good resistance to wear but also exhibits strong green light emitting under ultraviolet(UV)*** is the best wear-resistant self-sensitive coating which has potential industrial *** the coating wore or broke,the emitting intensity will decrease or disappear.
