Abstract

Surface treatment can effectively enhance the corrosion resistance of parts， but its improvement degree needs to be determined by specific corrosion test and corresponding evaluation methods， and the corrosion method and test results should have good reproducibility.In view of the long time to carry out corrosion evaluation in the environment close to the actual use of parts， it is very important to design reasonable accelerated corrosion test conditions and methods.This paper discussed the environmental corrosion characteristics of surface-treated components and the corresponding corrosion test methods， characteristics and evaluation standards， starting from the evaluation of the characteristics of corrosion test conditions and corrosion characteristics of surface-treated components.Moreover， the characteristics of salt spray， accelerated corrosion test and atmospheric environment corrosion of surface-treated components， such as the placement angle of parts in salt spray test， the thickness of surface water film， the influence of environmental temperature and humidity， and the corrosion rate， were analyzed and discussed， which provided supports for the scientific evaluation of the corrosion resistance of surface-treated components.

Key words： surface-treated components; cyclic accelerated corrosion test; corrosion result evaluation; salt spray test
