THE ANALYSIS ON CORROSION PROPERTY OF GRAY CAST IRON TREATED BY GAS MULTI-ELEMENT PENETRATION

The surface of gray cast iron can form the nitride layer by gas multi-element penetration,the analysis of nitride layer was made by the XRD and SEM about the phase structure and section appearance. The results show that the surface of material treated by gas multi-element penetration in a short time formed the white layer which was composed of Fe2N and Fe3N, diffusion layer was composed of iron nitride and carbide. And so the corrosion resistance improved obviously.
