| 摘 要： | 采用氧乙炔火焰喷涂技术,在镁合金AZ31B表面制备Al2O3纳米陶瓷涂层。采用X射线衍射(XRD)、扫描电镜(SEM)分析复合陶瓷涂层的组成及组织形貌,并对其热震性能、致密性、耐磨性和耐蚀性进行测试。结果表明,热喷涂纳米陶瓷涂层中有AlTi3、Al2TiO5等新相生成,组织更为致密,颗粒熔化程度较高,涂层热震性能、致密性、耐磨性和耐蚀性明显优于热喷涂微米陶瓷涂层。热喷涂纳米陶瓷涂层热震次数可达40次,说明涂层结合强度较高,清漆封孔后,孔隙率为0,致密性和耐蚀性都达到最好。

| Abstract: | Al2O3 based nanostructured ceramic coatings were prepared on the surface of magnesium alloy AZ31B by oxyacetylene flame spraying technology.XRD and SEM were used to analyze the composition and morphology of this composite ceramic coating.The thermal shock,compactness,wear properties and corrosion resistance of the composite ceramic coating were investigated.The results show that new phases of AlTi3,Al2TiO5 and so on are found in the nanostructured ceramic coatings.The structure of coatings become more dense... |
