| 摘 要： | 目的将耐磨材料、涂层制备技术以及磷光粒子的指示功能结合,发展一种简便经济的涂层监测技术。方法采用冷喷涂技术在T3紫铜基体上制备高铝青铜涂层及高铝青铜磷光复合涂层,利用SEM、EDS及荧光分光光度计等观察冷喷涂层的形貌,分析发光粒子的分布及涂层发光性能,并在室温条件下采用CSM往复式摩擦磨损试验机对干摩擦条件下涂层的摩擦磨损特性进行测试和分析。结果磷光粒子均匀分布在复合涂层中。涂层有较好的发光性能,经紫外线激发后发出裸眼可识别的黄绿光。磷光粒子的添加提高了高铝青铜磷光复合涂层的硬度,涂层摩擦表面磨痕较浅,呈轻微磨粒磨损特征,而高铝青铜涂层摩擦表面发生严重塑性变形,有剥落块及磨屑粘附在磨痕表面,呈粘着、疲劳磨损特征。结论磷光粒子的添加提高了复合涂层的抗磨性。磨损后的磷光复合涂层经紫外灯照射后,无荧光现象发生,能够实现检测涂层存在与否的功能。

| Abstract: | Objective To combine the wear-resistant materials, coating preparation technology and the indication function of phosphor particles, and develop a simple and economic coating monitoring technology. Methods A Cu-14Al-X coating and a composite coating of Cu-14Al-X and SrAl2 O4 : Eu2+,Dy3+ phosphorescence particle were prepared on T3 copper substrate by cold gas dynamic spray. SEM, EDS and fluorescence spectrophotometer were employed to observe the morphology of coatings and analyze the distribution and luminescent intensity of the embedded particles. Reciprocating friction and wear tester was used to evaluate the friction properties of the coatings under dry sliding condition at room temperature. Results Phosphor particles distributed homoge-nously in the cold sprayed Cu-14Al-X / phosphorescence composite coating. Under ultraviolet light, a strong luminescence was visible in yellow-green light. The micro-hardness increased with the increased dose of phosphorescence particles. A shallow track was observed on the worn Cu-14Al-X / phosphorescence composite coating, which indicated a slight abrasive wear occurred during the sliding process. For the Cu-14Al-X coating, intense plastic deformation, adhesion of small drop-cuts and abrasive dusts were observed on the worn surface, abrasive and fatigue wears dominated in the sliding process. Conclusion The addition of phosphor particles improved the wear-resistance performance of composite coating. Under ultraviolet light, no luminescence was visible on the worn Cu-14Al-X / phosphorescence composite coating, realizing the function of detecting the existence of coating. |
