调整盐则是比基盐的CNO含量更高的物料,主要用于补充、调整已经使用过而且CNO含量下降到工艺要求下限的盐浴,使盐浴中CNO的含量恢复到工艺规定的范围。

此时熔盐浴的CNO浓度为37%~40%。

c.盐浴的调整。当盐浴工作一定时间后,由于[N]、[C]的消耗,盐浴中的CNO降低,img196升高,当CNO低于规定值时,氮碳共渗效果减弱,满足不了要求,而且,img197的升高不但降低了盐浴的流动性,还会使渗层表面产生疏松。所以,当盐浴中CNO-接近工艺规定的下限时,应用调整盐对盐浴进行调整。

由于共渗零件时消耗了大量的[N]和[C],使盐浴中的CNO降低、CO2-升高。CN升高,盐浴的流动性变差,所以,3调整盐浴的目的就是提高CNO的含量,降低CO2-的含量,使3其恢复到工艺要求的范围。所以,这种盐浴的调整主要是添加(NH2)2CO,使其参加与盐浴中的Na2 CO3最简单的微信赚钱方法进行反应,达到调整盐浴成分的目的。添加尿素的重量,可以参照成品调整盐的计算公式,但需将系数1.15变为3。

硫氮碳共渗实际上就是在氮碳共渗盐中加入硫元素,工件表面在渗入氮、碳的同时渗入硫的工艺过程。目前,在专业厂提供的作为硫氮碳共渗的盐中,已含有不小于1.5×10-3%~2×10-3%的S2-

在共渗过程中,以硫、氮为主渗入元素,所以,工件经硫氮碳共渗后,在最表面层有不大于10μm的FeS密集层,次表面层为含有FeS、Fe2(NC)、Fe3(NC)及Fe4 N的共渗层,再向里为以氮为主的扩散层。碳只能以碳化物的形式(如Fe3 C)存在于表面化合物层中。

(1)共渗盐浴中S2-的补充。在生产厂家提供的成品盐中,已含有不小于1.5×10-3%~2×10-3%的S2-,但在使用中,S2-会消耗,使含量降低,所以,应适时进行补充。在生产现场对S2-的化验比较困难,S2-的补充可依据经验进行。在正常使用情况下,每24h,按每100kg熔盐添加2~4g的K2 S。

(2) S2-含量的控制。根据处理工件使用的主要功能来考虑S2-的含量控制。

工件以提高减摩性能,提高抗擦伤、抗咬合性能为主时,盐浴中的S2-含量可控制为大于2×10-3%;以提高耐磨、抗疲劳性能为主时,盐浴中的S2-含量控制在0.5×10-3%~1.5×10-3%即可。

(3) K S在盐浴中有降低CN的作用。在硫氮碳共渗盐浴2中,K2 S的存在还会发生以下化学反应

img203

通过这些化学反应,可使盐浴中有毒的CN下降。有研究表明:由于K S的作用,可使共渗盐浴中的CN的含量从2最简单的微信赚钱方法 2.5%~3.0%下降至0.1%~0.8%。
