Gas boring began at 550-600 ° C. A flat and continuous layer was formed at 800-850 ° C; At higher temperatures, the fragility of the layer increased.

The temperature of 850 ° C is optimal, at which layers from a depth of to 200 μm are formed within 2-6 hours. Borered layers on steel 45 obtained in a gas medium when heating the TVHH have a micro -hardness of 1700-2000 kgf/mm2.
