真空渗碳与传统渗碳比较

普通渗碳 (Ordinary carburizing) 普通一个大气压的条件下进行的气体渗碳工艺 (Gas carburizing process under the condition of common atmospheric pressu re ) 缺点
热处理工艺的灵活性 (Flexibility of he at treatment proce ss )
内容对比 (content) 工作环境 (work environment)
真空渗碳 (Vacuum carburizing) 低于一个大气压的条件下进行的气体渗碳工艺 (Gas carburizing process under the condition of less than one atmosphere pressure)
设备费用 （Equipment cost）
优点 便宜 advantage cheap
优点
(不需要调节碳势的时间， 可处理表面碳浓度高于 1.3%的零件) (零件表面碳浓度要求差别大，需要很长的调节碳势时间。不能处理表面碳浓度高于 Advantage (no need to adjust the carbon potential of the time, can handle the surface carbon concentration is highe r than 1.3% of the parts) 优点 1.3%的零件) Shortcoming (two furnace parts surface carbon concentration requirements vary greatl y, need a long time to adjust the carbon potential. Can not handle surfac e carbon concentration higher than 1.3% of the parts
零件质量 （Parts quality ）
缺点
1.渗碳层表面碳量和能准确的控制 2 渗碳效果均匀 3 可缩短作业时间 4 渗碳后零件扔保持辉面状态 advantage 1 the carbon content and the depth of carburizing la yer is simple and accurate. 2 uniform carburizing effect 3 can shorten the operation time 4 after carburizing parts to maintain the status of the surface 4 after carburizing parts have crystal oxidation, the surface is gray 缺点 昂贵 shortcoming expensive 2 carburizing effect is not uniform 3 cycle length 2 渗碳效果不均匀 3 周期长 4 渗碳后零件有晶体氧化，表面有灰色 shortcoming 1 the surface carbon content and the depth of carburizing can not be controlled accurately.
