    摘要:

    本文采用一种新型的气体多通道送粉等离子喷涂技术制备得到了含有不同质量分数的ZrO2/Fe基非晶复合涂层。采用该技术可成功制得ZrO2颗粒均匀分布于非晶基体的复合涂层,且可实现第二相颗粒的比例调控。磨损实验表明,复合涂层的磨损性能较单一的Fe基涂层有了很大提高。同时,ZrO2颗粒的添加可提高耐蚀性能降低孔隙率。经实验表明,复合涂层的最佳耐蚀性能为ZrO2含量50%。

    Abstract:

    In the present study, a novel gas multiple-tunnel plasma spraying technology was adopted to fabricate amorphous Fe-based composite coatings with various contents of ZrO2. By this way, the ZrO2 particles were distributed homogeneously in the matrix and the proportion of the two phases in the composite coatings can be regulated. During the wear process, the wear resistance is improved for the composite coatings. Meanwhile, the introduction of ZrO2 improves both the corrosion resistance and porosity. Therefore the best corrosion resistance is obtained for the composite coating with 50% ZrO2.
