本文研究了SAE8719钢试样经等离子渗碳和气体渗碳后渗层中的奥氏体晶粒大小及残余奥氏体量与高周弯曲疲劳强度的关系。气体渗碳的试样弯曲疲劳强度明显地优于等离子渗碳试样。
In this paper, the relationship between the austenite grain size and residual austenite in the layer of SAE8719 steel after plasma carburizing and carburizing by gas carburizing was investigated. The bending fatigue strength of gas carburized specimens is obviously better than that of plasma carburized specimens.
