| 摘要: |
| 采用真空热压烧结法在45＃钢基体上制备高铝青铜SrAl2O4:Eu2+,Dy3+磷光粒子自敏复合涂层,利用SEM、XRD和荧光分光光度计研究分析烧结复合涂层的结构及发光性能．结果表明:烧结复合涂层组织主要由高铝青铜烧结相、SrAl2O4的低温α相和高温β相共同组成,界面处主要以机械结合为主,并存在部分微区焊合点,涂层的发射光谱是典型的Eu2+的4f5d→4f特征发射谱,烧结复合涂层表面发光强度受金属杂质、温度、压力、粉末粒度因素的影响． |

| Abstract: |
| Cu-14Al-X and SrAl2O4:Eu2+, Dy3+ phosphorescence particle composite self-sensitive coatings were prepared on 45＃ steel by vacuum hot-pressing sintering. Microstructures and luminous performances of the coating were investigated by scanning electron microscope, X-ray diffraction and F97fluorospectro photometer. Results shown that microstructures of the sintered composite coatings mainly consist of Cu-14Al-X sintering phases, low temperature α-SrAl2O4phase and high temperature β-SrAl2O4phase. It is mainly mechanical combination between coating and substrate, with welding points in some areas.Luminescent emission spectrum is the typical Eu2+ 4f5d→4f characteristic emission spectrum; Metal impurities, sintering temperature, sintering pressure and phosphorescence powder size are main factors that affect the luminescence property of the composite coating. |
