石墨颗粒 meaning in Chinese
graphite particle
Examples
- Friction and wear properties of az91 magnesium alloy and its hybrid composites reinforced with alumina fiber and graphite particulates
石墨颗粒混杂增强复合材料的滑动摩擦磨损性能研究 - As the eutectic time increases , the graphite morphology departs from sphericity to the abnormal morphology , and the roundness of the graphite particles decreases as well
随着共晶时间的延长，铸件的石墨形态逐渐偏离球形，向异常化趋势发展，石墨颗粒的圆整度随之降低。 - Graphite particle surfaces are coated by a layer of oxides equably through micrograph images . in addition , the coating effect of al2o3 - coated particle is the best and much homogeneously ; the effect of tio2 - coated particle is the worst and its self - nucleation was serious , while after al2o3 / zro2 - coated , the coating on graphite surface becomes much denser
通过形貌观察，表面均包覆上相应的氧化物，其中，以al _ 2o _ 3的包覆情况最好，包覆较均匀；以tio _ 2的包覆情况最差，自身形核最严重，经过双层复合包覆后石墨颗粒表面的包覆层更加致密。 - The results indicate that the fracture toughness is influenced markedly by the different base structure of vermicular east iron and by the form of graphite ; unlike steel , the fracture toughness of vermicular cast iron increases with the yielding strength , while drops drastically with the increase of ratio of graphite grain length to thickness
试验结果表明，蠕墨铸铁的断裂韧度受不同基体组织的影响比较明显；受不同石墨形态的影响显著，与结构钢不同，蠕墨铸铁的断裂韧度随材料的屈服强度增大而增大，随石墨颗粒的长厚比增加会急剧下降。 - The result of experiment showed that the reaction between ti and c is a thermodynamic course , when 2 wt % mg is added to melt , it can restrain the formation of fragility phase al3ti , and gained al matrix composite which contained tic reinforced particles only . because mg reacts with the forms a micro - high temperature field around the oxide around the graphite particles and the oxygen gas which is brought by the immersion bell , and the reaction gives out a lot of heat energy , thus forms many high micro - fields in melt , which prompt the reaction between the al and ti
加入适量的mg ( 2wt )可以抑制tic al复合材料中的脆性相al _ 3ti的产生，生成仅含tic的铝基复合材料；由于活化剂镁在体系中与石墨颗粒周围的氧化物、以及外来的氧反应放热，在熔体中形成微高温区，促进al - ti反应，同时， al - ti反应也是放热反应，因此体系中的内能急剧增大，促使al _ 3ti分解以及ti朝c颗粒扩散，缩短反应的孕育时间。
