A method of surface hardening of products by means ofathermal boron facing is proposed. A comparative analysis of this approach and widespread chemico-thermal treatment (CTT) is presented. The authors highlight such obvious advantages ofathermal boron facing as energy saving, the possibility of carrying out the process at room temperature (CTT is performed at 900-950°C), abandoning heat-resistant steels for making muffles, minimum two-fold speeding up of the process, the possibility of boron facing of selected surfaces and their repeat boron facing as well as of applying the process for facing items of any weight and dimensions. Ecological cleanness and resulting ecological justification of the process are pointed out.
