摘要
为研究自配制的自保护硼氮共渗膏剂的性能 ,对 Q2 35钢、 4 5钢、T8钢和 GCr15钢等试样进行共渗试验。实验表明 ,4 5钢以选用 890℃共渗为宜 ;钢中的碳阻碍硼的渗入 ;涂层厚度以 4 mm为宜 ;膏剂硼氮共渗试样的耐磨性与固体硼氮复合渗相当 ,而比固体渗硼试样则好得多 ;经膏剂硼氮共渗的试样耐 10 0 % HCl和 30 % H2 SO4的腐蚀性与固体硼氮复合渗处理过的试样相当 ,二者均比 1Cr18Ni9Ti钢要好 ;Q2 35钢高温缓冷后易出现 Fe3N相。表明该膏剂共渗性能与固体硼氮相当 。
The composition of Boron nitriding paste,the mechanism of self protecting and the properties after treated were studied Experiments show that the properties treated by this paste are as good as that treated by powder boron nitriding,and these two are better than that of powder boronizing This pasty agent has high ability of boron nitriding and is easy to be operated with low costs After treated,the parts can be washed easily,and their surfaces are clean and have no corrosive spots
