In the process of the deposition of the pyrolytic graphite grid ’ s rough , experiment which adopts same discharge and proportion of those gases at different temperature has been done , the test which adopts different discharge and proportion of those gases at same temperature to deposit grid ’ s rough has also been done . at same time , the test which adopts different dilute gases at same technological condition to deposit the grid ’ s rough has been done . in order to obtaining the grid ’ s rough which thickness is able to use , the test has been done at different temperature and depositional time
在研究过程中,试验了在不同温度下采用相同的气体比例和流量沉积热解石墨栅极毛坯;还试验了在相同温度下,采用不同的气体比例、不同的流量沉积热解石墨栅极毛坯;同时,试验了在相同工艺条件下采用不同的稀释气体沉积石墨栅极毛坯;为了获得厚度合适的石墨栅极毛坯,试验了不同温度下采用不同的沉积时间来沉积毛坯;对不同温度下沉积的毛坯进行了x射线衍射分析、密度分析及晶相分析。
