The progress of research methods on atmospheric corrosion

The present status and development of research methods on atmospheric corrosion were comprehensively reviewed. Accelerated laboratory test, electrochemical measurements and in - situ monitor technology were emphatically introduced. Wet and hot test, salt spray test, periodic spray complex test, wet and dry intermittent immersion cyclic test, multi - factor complex accelerated corrosion test. While multi - factor complex accelerated corrosion test is the development trend in the future; electrochemical measurement technology for studying the corrosion mechanism in the thin layer electrolyte was generated: atmospheric corrosion monitor and Kelvin probe vibrating capacitor technique, polarization and impedance measurement methods was usually used to cyclic wet and dry accelerated test and also used to test electrochemical behavior of sample with rust in the immersion solution; the application of in - situ monitor technotogy contributed to launch the research on the mechanism of atmospheric corrosion from microcosmic aspect. In the end, this article puts forward the development trend of the future of atmospheric corrosion research methods.
