    摘要:

    本文采用一種新型的氣體多通道送粉等離子噴涂技術(shù)制備得到了含有不同質(zhì)量分?jǐn)?shù)的ZrO2/Fe基非晶復(fù)合涂層。采用該技術(shù)可成功制得ZrO2顆粒均勻分布于非晶基體的復(fù)合涂層,且可實(shí)現(xiàn)第二相顆粒的比例調(diào)控。磨損實(shí)驗(yàn)表明,復(fù)合涂層的磨損性能較單一的Fe基涂層有了很大提高。同時(shí),ZrO2顆粒的添加可提高耐蝕性能降低孔隙率。經(jīng)實(shí)驗(yàn)表明,復(fù)合涂層的最佳耐蝕性能為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.
