| 摘 要： | 以纳米Al2O3,和ZrO2为原料,利用大气等离子喷涂技术(APS)沉积了ZrO2,ZrO2-15%Al2O3,(体积分数,下同)和ZrO2-30%Al2O3三种涂层.运用FESEM,SEM,TEM,XRD和Raman Spectroscopy等分析技术对涂层相组成、显微结构进行了确定.测定了涂层的结合强度、显微硬度等性能.结果表明:Al2O3添加并不改变ZrO2涂层主晶相组成,但主晶相拉曼峰明显展宽.Al2O3颗粒以非晶形式存在于ZrO2颗粒间,有利于ZrO2涂层的增强增韧性能.ZrO2涂层中可观测到团簇颗粒与层状结构组成的双模结构.ZrO2涂层的沉积效率、结合强度与显微硬度可明显提高,有利于ZrO2涂层使用寿命与抗摩擦性能的改善.

| Abstract: | Three ZrO2 coatings with different Al2O3 contents were deposited by air plasma spraying using nanosize Al2O3 and ZrO2 powders as raw materials.The characterizations of zirconia-alumina composite coatings were studied by FESEM,SEM,TEM,XRD and Raman spectroscopy,and the properties such as cohesion strength,microhardness were also detected.The results show that the deposition efficiency,cohesion strength and microhardness can be considerably increased due to the addition of nanosize alumina,which are benefit t... |
