Conclusions

To obtain a thin boride coating with the maximum possible hardness on iron compacts and monolithic Armco iron. electrolytic boriding should be conducted at 950±10° for 1–1.5 h in an electrolyte consisting of 49%B2O3+34% Na2B4O7+17% B4C.

The microhardness of the coating is H 2300 when the density of the compact is 75%.
