考察了离子氮碳共渗中，气氛及基体中的碳量对渗层性能的影响。发现基体中碳阻碍氮的渗入，而气氛中微量碳促进氮的渗入。
The effects of the atmosphere and the amount of carbon in the matrix on the performance of the barrier layer were investigated in ion nitrocarburizing. Found in the matrix of carbon impede the infiltration of nitrogen, while the atmosphere of trace carbon to promote the infiltration of nitrogen.
