CeO_2对ZrH_(1.8)表面微弧氧化复合陶瓷层结构的影响
|
摘要
目的利用微弧氧化表面处理技术,通过改变电解液成分,在ZrH_(1.8)表面原位制得一层致密的复合陶瓷层。方法通过在电解液中添加CeO_2颗粒,采用恒压模式对氢化锆(ZrH_(1.8))表面进行微弧氧化处理,利用扫描电子显微镜(SEM)、X射线衍射仪(XRD)、涂层测厚仪、涂层附着力自动划痕仪,分析陶瓷层表面和截面形貌、相结构、厚度及其与基体的结合力,通过Archimedes排水法对所制备陶瓷层的致密性进行定量分析。结果 CeO_2颗粒的添加有利于陶瓷层的生长,与不添加CeO_2颗粒所制得的陶瓷层相比,加入CeO_2后,陶瓷层的厚度有所增加,陶瓷层与基体的结合力由81 N增大至104 N。XRD分析表明,陶瓷层中出现CeO_2特征峰,可知CeO_2在微弧氧化过程中成功地吸附在陶瓷层表面。不添加CeO_2时,陶瓷层的孔隙率为14.22%;添加CeO_2后,陶瓷层的孔隙率降低至5.79%。结论 CeO_2颗粒的加入可有效提高基体ZrH_(1.8)与陶瓷层的结合力,降低了陶瓷层的孔隙率,使氢化锆表面微弧氧化陶瓷层的致密性得到改善。
The work aims to prepare a dense composite ceramic layer on ZrH_(1.8) surface by changing the composition of electrolyte through micro-arc oxidation technology. ZrH_(1.8) was micro-arc oxidized through CV mode by adding CeO_2 particle inelectrolyte. Scanning electron microscope(SEM), X-ray diffraction(XRD), coating thickness gauge, coating adhesion automatic scratching device were used to analyze the surface and cross section morphologies, phase structure, coating thickness and adhesion between ceramic layer and substrate of the ceramic layer. The compactness of ceramic layer was analyzed with the Archimedes drainage method. CeO_2 particles were contributive to the growth of ceramic layer. The adhesion between ceramic layer and the substrateof the ceramic layer added with CeO_2 particles from 81 N to 104 N compared with the ceramic layer without CeO_2 particles. From XRD analysis, the ceramic layer had CeO_2 characteristic peak and CeO_2 was successfully adhered to the ceramic layer surface during micro-arc oxidation. The porosity of the ceramic layer without CeO_2 particles was 14.22%,while the porosity of the ceramic layer with CeO_2 particles reduced to 5.79%. The CeO_2 particlescan effectively improve the adhesion between ZrH_(1.8) and ceramic layer and reduce the porosity of the ceramic layer to make the micro-arc oxidation ceramic layer on ZrH_(1.8) surface more compact.
