固体加炭为目前我国工厂中作高硬度表面硬化的主要方法,气体加炭由於设备关系一时尚不能被普遍采用,液体加炭也必须有专配盐槽,因此如能控制好加炭的深度与浓度,固体加炭仍有其工艺与经济上的价值。 关於加炭的控制在过去一般只管深度,对於炭素浓度及其沿深度的分布一般未予以 Solid plus charcoal factory in China for the current high hardness of the main method of hardening the surface of the gas plus charcoal as a device can not be a general trend of fashion, liquid plus charcoal must also be equipped with a special salt tank, so if you can control the depth of carbon Concentration, solid carbon addition has its process and economic value. The control of carbon additions has generally been only the depth in the past, and the distribution of carbon concentration and its depth along the depth is generally not
