Effect of Gas Nitriding on CO₂ Corrosion Behavior of 40Cr Steel

Abstract:

In this paper, 40Cr steel was gas-nitrided for varying time. The microstructure and microhardness of the nitrided layer were examined by means of optical microscope and microhardness tester. The CO₂ corrosion behavior of 40Cr steel influenced by nitriding was studied using high temperature high pressure autoclave. The SEM, EDS and XRD technique were adopted to study the characteristics of CO₂ corrosion scales on 40Cr steel. The results show that the pitting is generated for all the un-nitrided and nitrided specimens, however, the corrosion tendency and corrosion rate decreases with nitriding time increasing, mainly due to the compact of FeCO₃ formed on the surface.
