| 摘 要： | 采用化学沉积方法获得Ni-Zn-P-TiO2复合镀层.采用X射线衍射、扫描电子显微镜、能谱分析等手段对复合镀层进行表征,研究了不同热处理状态下复合镀层的显微硬度、耐蚀性及耐冲蚀特性.结果表明,复合镀层由锐钛矿的纳米TiO2颗粒和过饱和的镍固溶体所构成.对经过不同热处理温度后复合镀层的分析表明,300℃以下热处理时,复合镀层衍射图无明显变化；加热至400℃时,有Ni3P析出；加热至500℃时,有Ni5Zn12析出.经400℃×1 h热处理,复合镀层具有最大的硬度值.复合镀层经300℃×1 h热处理后质量损失最低,有最好的耐蚀性能.在介质流速为36 ml/s、冲击角度为45.条件下,经过300℃× 1 h热处理后的复合镀层质量损失最低. |
