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，利用原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；選擇適當的熱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；採用分步碳化法可以提高形核密度，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還能造成高的表面缺陷密度，形成更多的形核位置。 -
The main reason are as following : on one hand, the nd - rich phases in the hydrogen desorpted powders is so brittle that they are easily milled too fine and some are run off seriously, and then inducing low density. on the other hand, the alignment of the magnets prepared by hydrogen desorption are much low. so the hydrogen desorption process should be modified, and the solution methods can be the substitution of traditional ingots with strip cast, the enhancement of the alignment magnetic field and the addition of nd - rich phase or ( and ) lubricant before the press
主要原因是hd磁粉中的富釹相較脆，在球磨時容易被磨成超細粉而造成過量流失和使磁體燒結不夠緻密；另外一個原因是hd法燒結磁體的易磁化軸的取向度較低，為了提高hd磁體的b _ r和（ bh ） _ （ max ）可對hd工藝進行改進，改進的方法可以是用鑄片代替鑄錠，提高成型磁場強度以及在磁粉成型前加富釹相和潤滑劑。 -
