引言真空技术是在1927年发明的,但是直到六十年代热处理工作者才开始予以重视。近十多年来,随着核技术、空间技术和电子计算机生产技术的发展,对金属材料提出了越来越复杂的技术要求,包括:耐高温、耐高压、抗腐蚀、抗氧化以及耐冲击、耐磨损等,用一般的热处理技术已不能满足,只有用真空热处理才能够达到这些要求。真空热处理就是在这种需要下才迅速发展起来的。因此发展真空热处理技术是发展现代尖端科学技术必须解决的一个重要课题之一。
Introduction Vacuum technology was invented in 1927, but heat treatment workers did not begin to pay attention until the 1960s. In recent ten years, with the development of nuclear technology, space technology and computer production technology, more and more complicated technical requirements have been put forward for metal materials, including high temperature resistance, high pressure resistance, corrosion resistance, oxidation resistance and impact resistance , Wear resistance, with the general heat treatment technology has been unable to meet, only with vacuum heat treatment to be able to meet these requirements. Vacuum heat treatment is developed rapidly under such a need. Therefore, the development of vacuum heat treatment technology is one of the important topics that must be solved in the development of modern cutting-edge science and technology.
