稀土氧化物对刚玉系高温自润滑材料组织结构与性能的影响
Effect of rear-earth oxide on the microstructure and properties of Al2O3-based self-lubricating materials
摘要
Abstract
The effects of Y2O3 on the microstructure and properties of Ai2O3. based self-lubricating materials were systematically studied by means of XRD, SEM and AFM. The experimental results indicate that Y2O3 can modify the materials microstructure, reduce the crystal size and make the body more compact, effectively improve the intensity, toughness and creep resistance under frication condition at high temperature, and it can promote the transformation of surface structure to nanophase-structural layer, exhibit hydrodynamic lubrication so that friction and wear behaviors decreased obviously and the materials possess favorable self-lubricating properties at high temperature.关键词
