摘要
为了提高T10钢模具的硬度及耐磨性,笔者对其表面进行液体盐浴渗硼处理。设计L9(34)正交试验,研究盐浴配方中SiC,B4C和KCl含量及渗硼温度对渗层组织及性能的影响。结果表明:B4C含量对渗层厚度和耐磨性的影响最大;随SiC含量增加,渗硼层厚度和耐磨性均升高;随B4C含量、KCl含量及温度的升高,渗硼层厚度和耐磨性先升高后降低;并得到较佳的渗硼配方和渗硼温度。
In order to improve hardness and wear-resistance, boride layers were prepared on T10 steel by the salt bath boronizing method. The L9 （34） orthogonal experiment was designed by changing the content of SiC, B4 C, KCl and boronizing temperature to find the optimum proportion and the microstructure, thickness and the wear-resistance property of the boride layer were studied. The results showed that the influence of B4 C on thickness and wear resistance of layer was the largest. With the content of SiC increasing, thickness and wear-resistance property increases. With the content of B4 C, KCl and boronizing temperature increasing, the thickness and wear resistance property increases at first and then decreases. The optimum proportion by weight of borax, cryolite, Cr2O3 , SiC, B4C, KCl was 50 ： 20 ： 5 ： 12 ： 5 ： 20, and the optimum boronizing temperature was 910 ℃.
