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.
