Effect of Plasma Hardening on Chromium Steel Corrosion Resistance

详细

Plasma hardening by a standard UDGZ-200 unit makes it possible to provide not only a marked increase in steel 20Kh13 hardness and wear resistance, but also an improvement of corrosion resistance. Under experimental conditions, the corrosion resistance of steel 20Kh13 after hardening increased by a factor of 1.86, but decreased somewhat (by 15%) in the transition area to unhardened metal.
