摘　　要：在相同温度下,对45钢和T10A钢进行不同时间的稀土盐浴渗铬,结果表明:随着渗铬时间的延长,渗铬的效果,在总体上呈增加的趋势,45钢在4h就可以达到较好效果,而T10A钢则在6h达到较好效果。Effects on 45 ＆ T10A steel in different process time of salt-bath chromizing adding rare-earth were studied. The results show that： at same temperature, 45 steel can reach considerable result in four hours, but the effect of T10A were getting better with time and reach considerable result in six hours.
