| Abstract: | In order to improve the anticorrosive performances of the metal parts of carbon-carbon composite which is used to make aircraft braking system, anticorrosive treatment was performed on the surface of metal parts with QPQ salt bath techniques. The metallographic texture and hardness gradient were analysed after nitriding. Salty fog test was carried out on the nitried metal parts and the anticorrosion ability was investigated. Experimental results show that the strength and anticorrosive ability can meet the application needs by surfacially treating the metal parts of aircraft braking system with QPQ techinique. |
