Method for measuring the corrosion of copper in H2S and SO2 containing air using surface color change

摘要

The present invention relates to the atmospheric corrosion of copper in sulfide-containing air by weight weight (W) = 3.19 K + 1.55, K = (redness of copper specimens before initial exposure test)-(redness of copper specimens after corrosion) Disclosed is a method of measurement using a function of weight-weight, + (yellowness of copper specimens before initial exposure test)-(yellowness of copper specimens after corrosion).
