Protective Measures of the Different Materials Joint Structure of Aircraft in Harsh Environment

Corrosion of the different materials joint structure is the main form of aircraft corrosion in harsh environment. The basic corrosion characteristics, corrosion causes and influence factors of the different materials joint structure of aircraft are analyzed in harsh environment. And the protective measures are put forward, including structual material selection and detail design,surface protection, maintenance, protective measure improvement of joint structure,localized corrosion repair.
