粉末化

Main reasons:(1) the concentration of inking oil is not sufficient, permealbe gompound, even if the paper texture is not very loose, will for excessive infiltration, resulting in an imprinted Powdering;(2) the silver and gold and silver ink is made of powder and inking oil leveling, and for the parents and poor performance.

主要原因：( 1 )调墨油的浓度不足，渗透性物质含量较多，即使纸张的质地不是很疏松，也会由于连接料的过量渗透，造成印迹粉化；( 2 )金银墨是由金银粉末与调墨油调配而成的，粉末与连接料的亲和性能较差。

It is very detrimental to materials performance. From the viewpoint of the effects of PPB precipitation on the frature of hipped P/M Rene'95, the surface segregation and reaction in Rene'95 powder metallurgy superalloy were analyzed by modern surface techniques and by electron microscopy. The mechanisms of the formation and reduction of PPB precipitation are revealed.

Results show that at 500℃ polycarbsilanedecomposed into noncrystallized SiC and free caron and impurities which hinder the densificationof the composite are also found during the above decomposition process, with the increase ofheating temperature, the noncrystallized SiC can be transformed into β-SiC.

一般传统的制备方法是，向C和SIC粉末中添加烧结助剂B，B；，A12O；；AIN等球磨混合，采用粉末冶金热压烧结；尽管采取了一些特殊的工艺手段和添加烧结助剂的方法，但该材料须在高于2000t时烧结且致密化效果较差［'1。

After Pressureless Sintering the densification behaviour of the SiC-based powder mixtures was observed to be markedly dependent not only on the type and amount of sintering aids used, but also on the crystal structure of the SiC powder.

经过常压烧结致密化行为的碳化硅基粉末混合物被观察到明显不仅仅取决于类型和数量烧结助剂使用，而且也影响到晶体结构的碳化硅粉末。

Anatase of unaged gel powder owned faster crystalline growth rate and worse aggregation during calcination than that of aged gel powder due to the existence of much more amounts of OH- in unaged powder.

未经过陈化处理的胶体粉末在煆烧过程中其锐钛矿晶粒成长较为快速且造成较为严重的凝聚，可能为粉末中含有较多的氢氧基所造成。

Panzhihua-Xichang area in Sichuan is abundant in vanadic titianomagnetite deposit. Because vanadium and titanium are transition metals and the difference between their atomic numbers is only 1, titanium carbide and vanadium carbide are refractory, high hardness and thermodynamically stable metal carbides.

而采用粉末冶金原位合成法不但可以解决铸造法因增强相体积分数增加及增强相与铁基体的密度差异而导致的铸造缺陷以及SHS的致密化问题，而且克服了粉末冶金法存在的增强体与基体之间结合不良的问题。
