  1. This thesis reports some results on the hot press sintering of nano - composite wc - co powder, which is prepared by spray pyrogenation & continuous deoxidization and carbonization process

    本課題採用壓燒結技術對以噴霧解?連續制備的納米復合wc - co粉末進行了壓燒結研究。
  2. By increasing the h2 dilution ratio, it is found that atomic hydrogen can selectively etch amorphous phase and stabilize crystalline phase. from the study on the distance from substrate to catalyzer, choosing a proper distance can ensure the gas fully decomposed, while a relatively low substrate temperature can cause the nanocrystalline particles to lose mobility and keep their sizes. the pre - carbonization process can enhance the nucleation density and make the growth of high quality nanocrystalline p - sic films much easier

    實驗結果表明:隨著工作氣壓的減小,薄膜的晶粒尺寸有所減小;通過提高氫氣稀釋度,利用子氫在成膜過程中起的刻蝕作用,可以穩定結晶相併去除雜相;選擇適當的絲距離能保證反應氣體充分分解,又使襯底具有較高的過冷度,是形成納米薄膜的重要條件;採用分步可以提高形核密度,有利於獲得高質量的納米- sic薄膜;襯底施加負偏壓可以明顯提高襯底表面的基團的活性,因負偏壓產生的離子轟擊能造成高的表面缺陷密度,形成更多的形核位置。
  3. The formation mechanism of titanium nitride powders by reduction of carbon and nitridation was researched by method of continuous weighing. the possibility to obtain the titanium nitride from this process was asserted by thermodynamical analysis and by the means of x - ray diffraction and sem
