[Application of spectral analysis on atmosphere corrosion research].
This paper applied two methods of spectrum analysis to measure the rusty layer of samples atmosphere corrosion from Qingdao and Chengdu. The main component elements and rust phase of rusty layer are obtained. It showed that the relative content of the elements and rust phase varies with the change of corroded environment and time. The result, relative content of each rust phase of A3(1) rusty layer sample have following relation: gamma-Fe00H > alpha-Fe00H > delta-Fe00H, and, relative content of other rusty layer samples have relation: gamma-Fe00H > delta-Fe00H > alpha-Fe00H, in the rusty layer of low-alloy steel, there are the alloy elements of rest body.
