1) run hard grind
难磨粒子
2) wear resistant particles
耐磨粒子
1.
The effects of the content of wear resistant particles and activated sintering agents on the mechanical and friction and wear properties of copper alloyed based dynamic seal materials have been studied,moreover, microstructure of the materials was observed.
研究了耐磨粒子和活化烧结剂的含量对其机械性能和摩擦磨损性能的影响 ,并且观察了其显微组织。
2.
By adding vanadium and niobium into ordinary high Ni-Cr cast iron and tempering treatment, there were small wear resistant particles crystallizing out and distributing uniformly and dispersedly in the matrix; the graphite in both the outer layer and core area of the roll became smaller and more rounded; carbides distribution in outer layer became more uniformly and dispersedly.
通过在普通高Ni-Cr铸铁中加入元素V和Nb以及进行回火处理,在基体中结晶出均匀弥散分布的细小耐磨粒子,使轧辊外层及芯部的石墨变得细小圆整,外层碳化物均匀分散,辊身表面硬度﹑硬度落差、辊颈抗拉强度等力学性能指标均满足轧辊的使用要求。
4) Wearing particle
磨屑粒子
5) Hardened size (The coal size which is about equal sieve aperture size and hard to size)
难粒
6) magnetic abrasive particles
磁性研磨粒子
补充资料：初级粒子和原级粒子
分子式：
CAS号：
性质：又称初级粒子和原级粒子。利用各种化学反应方法得到的最初粒子(晶粒)。一次粒子的大小约为0.005～1μm，比筛分的极限小得多，在介质中有相当高的稳定性。
