Raising the Operating Properties of Die Steel 5Kh2GF by Creating Carbonitride Layers by Thermochemical Treatment

Аннотация

The effect of carbonitriding of nickel-free die steel 5Kh2GF in a highly active environment based on amorphous carbon and potassium ferricyanide is studied. The temperature of the carbonitriding process is varied within 800 – 900°C, and the duration is varied from 3 to 8 h. The structure and the hardness of the steel are determined. The wear resistance of the steel after the carbonitriding increases by a factor of 4 – 6.
