摘要
Abstract
The corrosion morphology,microstructure and corrosion products of the heat exchanger tubes were studied by the method of optical microscope,scanning electron microscope with EDS and XRD.The reason of corrosion was analyzed.The results show that the uniform corrosion which induced by combined action of H2S-NH3-HCN-H2O occurred and the tubes had been perforated in the serious corrosion ar-ea.Some protective methods were also proposed.关键词
