摘要

结合磨削表面X射线衍射定性分析与定量计算

研究了"晶内型"微-纳米复相陶瓷材料超声振动磨削表面层与基体之间的过渡层的微观结构.X射线衍射分析表明:二维振动磨削和普通磨削表面均以-αA l2O3和四方相Z rO2为主

存在少量的单斜相Z rO2

磨削表面无非晶相产生;磨削表层和基体之间的过渡层的X射线衍射峰具有半峰宽化现象

磨削表面和基体之间的过渡层是以晶格畸变为主的塑性变形层

细粒度砂轮二维超声振动磨削微-纳米复相陶瓷材料主要以塑性变形机理被去除.

Abstract

The "transgranular" internal micro-nano structure of ceramic composites

the qualitative analysis and the quantitative calculation of the crystalline size were discussed.With X-diffraction technique

the surface and subsurface topography of the two-dimensional ultrasonic vibration grinding ceramics were especially analyzed.The qualitative analysis and the quantify calculation of crystal size and lattice distortion by means of X-diffraction results indicated that the transition region between grinding superficial and basal matrix was ductile deformation area of lattice distortion

the surface phases were composed of α-Al2O3

t-ZrO2 and small quality m-ZrO2. There is not non-crystal in ground surface

and the full width at half maximum(FWHM)phenomenon of X-ray diffraction were observed.Under definitive grinding conditions

elastic deformation made the principal removal mechanism of Al2O3-ZrO2 ceramic micro-nano composites under two-dimensional ultrasonic vibration grinding.
