摘要

将等离子喷涂级Al2O3-13TiO2和ZrO2粉末以不同比例（80wt%Al2O3-13TiO2+20wt%ZrO2、20wt%Al2O3-13SiO2+80wt%ZrO2和50wt%Al2O3-13TiO2+50wt%ZrO2）物理混合，并使用相同的等离子喷涂参数在生物医学Ti-13Nb-13Zr合金上等离子喷涂。利用扫描电子显微镜和X射线衍射仪对喷涂后的涂层进行了微观结构和相分析。结果表明，与其他两种涂层相比，80%Al2O3-13TiO2+20%ZrO2涂层具有更高的耐腐蚀性和耐磨性，是一种有利于生物医学应用的涂层。图形摘要

Properties of Plasma Sprayed Al2O3-13TiO2 and ZrO2 Blended Coatings on Biomedical Alloy

Plasma spray grade Al2O3-13TiO2 and ZrO2 powders were blended physically in different proportions (80 wt% Al2O3-13TiO2 + 20 wt% ZrO2, 20 wt% Al2O3-13TiO2 + 80 wt% ZrO2 and 50 wt% Al2O3-13TiO2 + 50 wt% ZrO2) and plasma sprayed on biomedical Ti-13Nb-13Zr alloy using identical plasma spray parameters. Microstructural and phase analyses of the as-sprayed coatings were carried out using scanning electron microscopy and X-ray diffractometry. Results showed that the 80% Al2O3-13TiO2 + 20% ZrO2 coating had enhanced corrosion and wear resistance compared to the other two compositions and appeared to be a propitious coating for biomedical application.
