英文摘要	It is very important for coating to detect integrity and working life in corrosive environment. The self-sensitization luminescent coating were fabricated by electroplating technique from a modified Watts bath combined with blue-emitting (BaMgAl11O17:Eu2+), red-emitting (Y2O3:Eu3+), and green-emtting (CeMgAl11O19:Tb3+) rare-earth fluorescent particles. The surface morphology, microstructure, wettability, deposition rate, hardness, and self-sensitization luminescent property of the obtained composite coatings were characterized by using fluorescence spectrophotometer, surface profile measuring instrument, vickers, scanning electronmicroscope (SEM), X-ray diffraction (XRD), and electrochemical test techniques. The results show that surfactants of non-ionic PEG (polyethylene glycol) and cationic CTAB (cetyltrimethylammonium bromide) effectively improve the particles deposition rate. The fluorescent particles shows different wettability and matching with nickel, which have different effects on microstructure of the composite coatings. Y2O3:Eu3+fluorescent particles change the coating crystal orientation and grain refinement, BaMgAl11O17:Eu2+fluorescent particles make the coating morphology presents knot. The coating hardness is increased obviously in composite coatings containing Y2O3:Eu3+and CeMgAl11O19:Tb3+particles. The fluorescent particles show different luminescent characteristics after corrosion, indicating good self-sensitization and effective monitor on the integrity of the composite coatings. © 2017, Science Press.
