智能制造若干问题的再认识

应用Ｘ射线衍射谱和激光喇曼散射光谱分析了ＰＳＺ陶瓷精密磨削表面的相变分布特征．结果表明磨削变质层的磨削相变是不均匀的．磨痕内的相变量大于磨痕处的相变量；磨削表面的相变量大于次表面的相变量；相变层深分布与材料有关，相变层深度远大于所采用的磨削深度．

The Distribution of Phase Transformation in the Modified Layer of PSZ Ceramics

By an XRD adn laser Raman scattering spectrum analysis, the distribution of phase transformation on the ground surfaces of the PSZ ceramics 2Y PSZ and 9 Mg PSZ is investigated. It has been found that the transformation due to grinding in the modified layer is nonuniform. The quantity of transformation inside the grinding crack is larger than that outside and that on the ground surface is larger than that on the sub surface. The depth dependent distribution of transformation is dependent on the properties of PSZ ceramics and the depth of transformation is larger than that of the wheel cut.
