真空热处理是本世纪五十年代开始出现的。当时由于核技术、空间技术、原子能工业、电子工业和飞机制造工业的发展,要求有新的热处理设备来处理诸如钨、钼、钽、铌、钛等高温合金的金属材料,使之在热处理过程中避免氧化、脱碳、增碳、减小热处理变形并具有良好光亮的表面状态等特点。于是真空热处理 Vacuum heat treatment began in the fifties of this century. At that time, due to the development of nuclear technology, space technology, atomic energy industry, electronics industry and aircraft manufacturing industry, new heat treatment equipment was required to handle the metal materials of superalloys such as tungsten, molybdenum, tantalum, niobium, titanium and the like in the heat treatment process To avoid oxidation, decarburization, carbon, heat treatment to reduce the deformation and has a good surface characteristics such as bright. Then vacuum heat treatment
