刚玉

The combination of corundum-coated cBN abrasive with vitrified bond is better than that of Ti-coated or un-coated cBN. And the buffer layer from cBN abrasive, corundum coating to bond is perfect because part of corundum coating melts into vitrified bond to build dentation combination.

表面涂覆刚玉和镀覆Ti的cBN磨粒与结合剂的结合效果均比未镀覆的好，但涂覆刚玉比镀覆Ti的效果更好，刚玉涂层以牙形溶入结合剂中使得磨粒、镀层和结合剂三者过渡良好。

Based on analysis of the grinding shortcomings associated with brown emery wheel of the roller s skew tooth top-surface,a method was proposed,which used CBN grinding wheel in substitution for traditional brown emery wheel.

Firstly, the fly ash is separated into three parts according to its mineralogical composition, they are ferruginous spheres, mullite-corundum and glass phases. Secondly, the contents of these elements of the original fly ash, the ferruginous spheres and the mullite-corundum are determined by chemical analysis and ICP-MS, respectively, and thus the element contents in the glass phase can be obtained by calculation.

首先根据高铝粉煤灰的物相组成特点采用新的分离方法将之分离为三个相：铁质微珠、莫来石－刚玉相以及玻璃相；然后分别用化学分析和ICP-MS测试主微量元素在高铝粉煤灰、铁质微珠以及莫来石－刚玉相中的含量，并结合相关数据计算出这些元素在玻璃相中的含量。
