A technology for hardening machine parts and tools by boronizing in molten calcium chloride with amorphous-boron powder in electrode salt baths has been developed with the aim of creating a closed cycle of utilizing the raw materials and the washing water. A process of boronizing that includes quenching and tempering of the boronized articles is described. The quenching medium is an ecologically sate and readily available aqueous solution of calcium chloride. The process envisages return of the melt components to the boronizing bath. Boronizing by the suggested method was tested for different classes of steel, namely, structural and tool steels for cold and hot deformation. The wear resistance of the boronized steels was studied.
