采用正交试验设计方法研制自保护硼氮共渗膏剂的最佳配比，分析了各组元对粘结现象的影响。利用热力学第二定律，判断各反应进行的方向，用ｘ－ｒａｙ衍射仪对粘结部分进行物象分析。结果表明，在自保护膏剂硼氮共渗过程中产生粘结是由于自保护壳体不够完整，在共渗过程后期氧的进入与工件表面发生化学反应所产生的 The optimal ratio of self-protection boron-nitrogen-containing ointment was developed by orthogonal experimental design method, and the influence of each component on the adhesion was analyzed. The second law of thermodynamics was used to judge the direction of each reaction and the object was analyzed by x-ray diffraction. The results show that the self-protective paste boron nitriding process of bonding is due to the self-protection of the shell is not complete, in the late osmosis process of oxygen and chemical reaction occurs on the surface of the workpiece
