The corrosion behavior of copper exposed in a simulated high H2S containing atmosphere was investigated by weight change measurement, scanning electron microscope with energy dispersive spectrometry and X-ray diffraction, while an non- equal interval grey model GM(1, 1) was established, of which the precision and forecast dependability were evaluated. The results indicates that the weight gain of Cu increase slowly at the initial stage, whereas increase rapidly at the later stage. Surface observation shows that the corrosion products on Cu were...
