文摘
- •
Oxidizing and nitriding-oxidizing treatment were performed for Fe-21Cr-9Mn alloy.
- •
These two heat treatments can protect the matrix from corrosion in liquid zinc.
- •
The alloy after nitriding-oxidizing treatment shows a best corrosion resistance.
- •
The reason is that the formation of the more compact and intact oxide structure.
- •
Corrosion of the modified alloy is caused by dissolution and localized corrosion.
