| 摘要 |
A method for improving the corrosion resistance, increasing the hardness, providing superior ductility, and reducing surface-cracking of a diffusion coating by nitriding and heating-treating the diffusion coating is disclosed. The nitriding and heat-treating may occur subsequently or simultaneously. Further, the disclosed method may be practiced subsequent to or incorporated as an intergral part of any known diffusion coating process which utilizes a heating step in a furnace having a cover gas. |
