由于真空热处理具有一些常规处理无法具备的优点,因此,在世界各国普遍受到重视。据1983年9月在意大利召开的第二届国际材料热处理大会统计,欧洲国家应用真空热处理的比重高达10％,而我国亦把真空热处理列为15项重点研究和推广应用热处理项目之一,对真空退火、油淬、气淬,真空渗碳、离子渗碳以及真空等温淬火,水淬的工艺先后进行了研究和应用,与此同时有很多单位进行了设备的研制,成功地制造了各类油淬炉、渗碳炉、离子渗碳炉、真空连续作业炉等。
Because vacuum heat treatment has some advantages that conventional treatment can not have, so it is universally valued in all countries in the world. According to the statistics of the 2nd International Material Heat Treatment Conference held in Italy in September 1983, the proportion of applications of vacuum heat treatment in European countries is as high as 10%. In China, vacuum heat treatment is also listed as one of 15 key research and promotion and application heat treatment projects. Vacuum annealing, oil quenching, gas quenching, vacuum carburizing, ion carburizing and vacuum isothermal quenching, water quenching process has carried out research and application, at the same time there are many units for the development of equipment, successfully manufactured various types Oil quenching furnace, carburizing furnace, ion carburizing furnace, continuous vacuum furnace and so on.
