vacuum degassing meaning in Chinese

真空除气
真空排气
真空脱泡
真空脱气

In order to consolidate the powder compacts into densified billets , the technique of vacuum degassing , encapsulating and warm pressing was adopted
提出了ti / al复合粉的制坯致密和真空脱气包套工艺。
We analyze the microstrain and density changing of the composite powders during pressing . the density evolution of ti / al composite billet became calm when the pressure get to 1000mp . the technique of vacuum degassing can reduce the content of atmosphere
分析了复合粉在冷压制过程中的微观变形过程,不同压力下的密度变化趋势,表明在冷压制压力达到1000mpa后复合粉预制坯密度变化趋于平稳。
The technique can avoid produce ti / al chemical compound in high temperature . the chemical compound would increase the difficulty of pressing . the research on vacuum degassing and temperature of pressing can acquire the ideal composite powders of highly
对ti / al复合粉进行真空脱气及低温热压制可以降低坯料中空气含量并提高粉末颗粒的界面结合强度,同时避免高温下生成tial基化合物增加致密难度,对真空脱气及压制温度进行研究,获得理想的致密度极高的复合粉末。
