摘要

中文摘要: 研究了TiO2含量对大气等离子喷涂Al2O3基涂层的晶体结构组成相、显微硬度、摩擦磨损性能和磨损机制的影响。选用重量百分比为0

13%

40%这3种TiO2含量参量

即纯Al2O3

Al2O3-13%(wt)TiO2和Al2O3-40%(wt)TiO2陶瓷涂层。采用XRD分析涂层的晶体结构组成相

Vickers显微硬度计评价显微硬度。采用SRV摩擦磨损试验机

通过AISI52100钢球和Al2O3陶瓷球2种材料本质差异甚大的对摩副

在干摩擦条件下评价涂层的摩擦磨损性能

并通过扫描电镜观察涂层磨损机制。结果表明

Al2O3基涂层的显微硬度随TiO2含量增加而降低;Al2O3基涂层皆显示出抗磨性能随TiO2含量增加而降低

而与对摩副材质无关。涂层中含有TiO2无益于提高Al2O3基涂层的摩擦磨损性能。

Abstract

Abstract:The effect of TiO2 content on crystalline structure and constituent phases

micro-harness

friction-wear performance and wear mechanisms of air plasma sprayed Al2O3 based coatings was studied. Three variations of 0

13% and 40% for TiO2 content in weight ratio percentage were selected

namely

pure Al2O3

Al2O3-13%(wt)TiO2 and Al2O3-40%(wt)TiO2 ceramic coatings. XRD was used to analyze crystalline structure and constituent phases of coatings and Vickers micro-hardness tester to measure micro-hardness of coatings. An SRV wear tester was employed to evaluate friction-wear performance of the coatings under dry condition using two types of wear counterparts with extremely discrepant material nature

i.e. AISI52100 steel ball and Al2O3 ceramic ball. Wear mechanisms were examined with SEM. The results showed that the hardness of coatings decreased with the increase of TiO2 content. The Al2O3 based ceramic coatings showed the same trend irrespective of material nature of wear parts

indicating that the wear resistance decreased with increasing TiO2 content. No strengthening in wear performance was obtained with Al2O3 based coatings with TiO2.
