We describe some specific features of the diffusion borating of steels in Na-B melt. We succeeded in obtaining high-quality single-phase coatings on steels with a total concentration of alloying elements less than 2 mass % and on high-strength cast irons. The maximum microhardness of these coatings is 22–23 GPa. The optimal borating temperatures are 900–950°C. At temperatures lower than 850°C, we observe the dissolution of certain components of steels and cast irons in Na-B melt initiated by boron.
