摘要

常用齿轮钢渗碳温度为930℃

提高渗碳温度至1000～1050℃能显著缩短渗碳时间

但易引起晶粒长人

因此发展了通过Nb、Ti、B微合金化

细化钢原奥氏体晶粒的高温渗碳齿轮钢。文中介绍了国内外高温渗碳齿轮钢的钢种成分、工艺特点、高温渗碳层组织控制和钢的疲劳性能的研究进展。

Abstract

The carburizing temperature of common gear steels is 930 °C

as the carburizing temperature of steel increases to 1 000 ~ 1 050 °C the time of carburization process can be remarkably reduced but it easily leads to grain coarsening. Therefore

the high temperature carburization gear steels are developed by Nb

B microalloying to fine original austenite grain size in steel. The research progress in gear steels for high temperature carburization at home and abroad including grade and chemical composition

process characteristics

control of structure in high temperature carburized layer and fatigue properties of steel is presented in this article.
