| 摘 要： | 用等离子喷涂技术制取了ＭＯ＋Ａｌ２Ｏ３－ＴｉＯ２、ＭＯＳ２＋Ａｌ２Ｏ３、ＴｉＯ２＋Ｃｒ３Ｃ２ＮｉＣｒ和ＭｏＳ２＋Ｃｒ３Ｃ２－ＮｉＣｒ复合涂层．利用ＳＥＭ、ＸＲＤ、和ＸＰＳ等技术．观察和分析了涂层的显微结构和喷涂过程中的物相变化及添加成分对涂层耐磨性能的影响．在ＭＭ－２００型磨损试验机上测定了涂层的滑动摩擦系数和磨损率．结果表明；Ｍｏ、ＭｏＳ２与Ａｌ２Ｏ３－ＴｉＯ２的结合性能较好，ＴｉＯ２、ＭｏＳ２在Ｃｒ３Ｃ２－ＮｉＣｒ涂层的气孔和裂纹处偏聚；添加ＭｏＳ２对Ａｌ２Ｏ３－ＴｉＯ２涂层的物相组成有明显的影响；适量的ＭＯ、ＭＯＳ２加入Ａｌ２Ｏ３－ＴｉＯ２中，可以降低涂层的摩擦系数和磨损率；而ＴｉＯ２、ＭｏＳ２加入Ｃｒ３Ｃ２－ＮｉＣｒ中，对涂层的摩擦磨损性能影响不大

| Abstract: | Mo Al2O3-TiO2 MoS2 Al2O3-TiO2 TiO2 Cr3C2-NiCr and MoS2 Cr3C2-NiCr coatings were deposited .by means of Plasma spraying.The microstructures andcrystallographic phases of the coatings were examined employing SEM,XRD and XPS respetively. The sliding friction coefficients and wear mass losses of the Al2O3-TiO2 based coatings against stainless steel and Cr3C2-NiCr based coatings against Plasma sprayed TiO2 coating were measured using MM-200 wear tester.The effect of coating compositions on their wear characteristics were discussed.The results obtained show that Mo and MoS2 adhered to Al2O3-TiO2 affect the crystallographic phase and improve wear characteristics of Al2O3-TiO2 coating.However,TiO2 and MoS2 accumulate at pores and cracks and have no obvious influences on the wear characteristics of Cr3C2 -NiCr coating. |
