Design of diffusing self - lubricating and wear - resisting ceramic sinter 扩散自润滑金属陶瓷耐磨烧结体的设计
Researches and applications of compound diamond core bit with sintered body 混合型金刚石烧结体取心钻头的研制及应用
The sintered temperature was one of key parameters to the relative density and grain size 烧结温度是决定烧结体致密度高低的主要因素。
Abnormal grain growth and its countermeasure in sintering of fine grained polycrystalline diamond compacts 细粒度金刚石烧结体中异常粒成长及其对策
The results show that the grain size of cosb3 grows with increasing sintering temperature or sintering time 结果表明:随着烧结温度的增加和烧结时间的延长,烧结体的晶粒有明显长大。
Low heating rate and high sintered pressure were profitably for reducing the rate of pore so as to increase the relative density of sintered body 低的升温速率和高的烧结压力有利于气孔的排出,降低气孔率,从而提高烧结体的致密度。
5 percent additional between the mo - cu sinter with ni nh4cl activator and the mo - cu sinter without n nh4cl activator , and the ni activator had the better influence than the nh1 添加活化剂的mo - cu烧结体比未加活化剂的烧结体相对密度一般高0 . 5 1 . 5个百分点。
At 1600 , 1650 , 1700 sintering temperature with carbon nanotubes , the mechanical properties were decreased as the increase content of the carbon nanotubes 而当添加碳纳米管时,在烧结温度为1600 、 1650和1700时,烧结体的力学性能均随着碳纳米管含量的增加而降低。
For the powder milled to amorphous state , because of its very fine structure , it is easy to occur phase transformation and has good size stability when sintered 研磨到非晶态的粉末由于元素达到原子尺度混合,大大缩短了扩散距离,不仅易于发生固态相变,而且烧结体尺寸稳定性好。
A series of ultra - fine , homogeneous powders and density pellets were synthesized , li3 . 4si0 . 4v0 . 6o4 as the matrix and the lithium salt and other oxides as the second phase O 。固溶体为基质,以不同种类的氧化物或理盐为第二相,合成了一系列复合理离子导体的超细粉体和均匀、致密的烧结体。
