Study on Corrosion Protection of 1Cr11Ni2W2MoV Steel in Acid Environment
High temperature,high humidity,and high salt fog in marine environment bring serious corrosion risk to Shipborne Aeroengine.1Cr11Ni2W2MoV stainless steel has good mechanical properties and oxidation resistance,which is an important material for a certain type of Shipborne Aeroengine.However,1Cr11Ni2W2MoV is very sensitive to Cl-,and it is very easy to corrode in the marine environment.In this paper,the samples of 1Cr11Ni2W2MoV stainless steel with Cu-Ni-Cr plating、nickel plating、Cd plating and TWL-12+TWL-20 coating were carried out for 192h acid salt spray,680h acid atmosphere.The result shows that Cu-Ni-Cr plating、nickel plating samples show small area corrosion after acid salt spray,while Cd plating samples show only discoloration and no obvious corrosion after the acid salt spray test,TWL-12+TWL-20 coating has no obvious change after the test,showing good corrosion resistance.
