摘　　要：为了解决传统气体渗氮热处理存在的氮势、渗层深度不可控,以及工件表面脆白层、不锈钢表面钝化膜严重阻碍渗氮处理顺利实施等问题,研发了预抽真空井式可控气氛渗氮新技术。运行实践表明,新开发的预抽真空井式可控气氛渗氮新技术不仅氮势、渗层深度可控,而且工件处理品质好,再现性高。In order to solve the problems existing in the traditional gas nitriding furnace, such as uncontrollability in nitrogen potential and nitrided layers, crisp white surface layer and surface passivation membrane which impeding nitriding treatment, researched and developed pre-vacuum pit controlled atmosphere gas nitriding furnace. The practice showed that new developed pre-vacuum pit controlled atmosphere gas nitriding furnace was controllable in nitrogen potential, nitriding layer depth, and the productes hve good quality and better reproduci- bility.
