An alternative powder-pack boriding powder mixture containing H₃BO₃ as boron source and commercial boriding powder containing B₄C as boronizing agent were used for boriding of GGG 70 type ductile iron. As a result of XRD analysis, while only Fe₂B phase was detected on the samples boronized with alternative boriding mixture, besides Fe₂B phase, small amount of FeB phase was also determined on the samples boronized with commercial powder. The growth kinetics of the boride layer forming on ductile iron was investigated and compared with literature studies. The value of boron activation energy for ductile iron was calculated as 184.67 kJ/mol. An empirical equation and a regression model were derived to estimate the thicknesses of boride layer as a function of the boriding parameters. The comparisons were made between the experimental boride layer thicknesses with estimated ones and the results were consistent with 99% accuracy.

使用替代的以H ₃ BO ₃作为硼源的粉末状粉末状硼化物粉末混合物和以B ₄ C作为硼化剂的市售粉末状硼化物粉末对GGG 70型球墨铸铁进行硼化物化。XRD分析的结果表明，除了Fe ₂之外，在用其他硼化物混合硼化的样品中仅检测到Fe ₂ B相。B相中，还测定了用市售粉末镀硼的样品中的少量FeB相。研究了球墨铸铁上形成的硼化物层的生长动力学，并将其与文献研究进行了比较。计算出球墨铸铁的硼活化能值为184.67 kJ / mol。推导了经验方程和回归模型，以估计硼化物层的厚度随硼化参数的变化而变化。在实验硼化物层厚度与估计厚度之间进行了比较，结果与99％的精度一致。
