一、前 言 真空热处理较其他热处理方法有很多明显的优点,如无氧化、无脱碳或增碳、表面洁净、变形小、有脱气净化作用、无公害等。由于在真空炉中很容易获得高速钢热处理所需的高温,因此,通常认为,真空热处理对于高速钢制工、模具和零件是最合适的。 First, the preface Vacuum heat treatment than other heat treatment methods have many obvious advantages, such as no oxidation, no decarburization or carbon, clean surface, small deformation, degassing purification, pollution-free and so on. Due to the high temperatures required for HSS heat treatment in vacuum furnaces, it is generally considered that vacuum heat treatment is most suitable for HSS construction, molds and parts.
