离子化学热处理是一类正在发展并且日益受到重视的表面强化工艺,包括铁素体状态下的离子热处理(如离子氮化、离子氮碳共渗、离子硫氮碳共渗等)和奥氏体状态下的离子热处理(如离子渗碳、碳氮共渗、离子渗硼、渗金属等)。离子化学热处理是在低气压(几百帕斯卡)辉光放电条件下进行的,工件的加 Ion chemical heat treatment is a growing and increasing emphasis on the surface strengthening process, including the ferritic state of the ion heat treatment (such as ion nitriding, ion nitrocarburizing, ion sulfur nitrocarburizing, etc.) and austenite State of the ion heat treatment (such as ion carburizing, carbonitriding, ion boronizing, infiltration of metals, etc.). Ion chemical heat treatment is carried out under low pressure (several hundred Pascal) glow discharge conditions, the workpiece plus
