A METHOD OF DEVELOPING EROSION RESISTANT HARD LAYER ON 13CR-4NI STAINLESS STEEL COMPONENTS

摘要

A method of developing erosion resistant hard layer on 13 Cr-4Ni Stainless Steel components comprising placing the turbine component in plasma ion nitriding equipment for carrying out plasma, nitro carburizing process in the presence of H2, N2 and C2H2 gases at a temperature range of 575-585�C and pressure in the range of 1.5-2.5 mbar for 20-24 hrs to achieve hardness of about 1100- 1400 HV upto a case depth of about 150 microns.
