阴极电解等离子体沉积金属-陶瓷涂层及金属掺杂Al2O3涂层研究阴极电解等离子体沉积金属/陶瓷涂层及金属掺杂Al2O3涂层研究

摘要：

阴极电解等离子体沉积（CathodicElectrolyticPlasmaDeposition,CEPD）是一种广泛应用于制备多种功能材料的方法，通过在阴极表面形成等离子体沉积金属、陶瓷等材料。本文研究了CEPD制备金属/陶瓷涂层及金属掺杂Al2O3涂层的制备方法、表征技术和性能。通过分析不同工艺条件对涂层结构和性能的影响，找到合适的工艺参数，制备出性能较优的涂层。同时探究了金属掺杂Al2O3涂层的制备方法及其掺杂剂对其性能的影响，研究结果表明掺杂元素可显著影响涂层的纯度、硬度、磨损性能等特性。本研究的结果可为CEPD方法制备金属/陶瓷涂层及金属掺杂Al2O3涂层的应用提供理论和实践基础。
