【摘要】 综述了铜在不同大气气氛中的腐蚀情况,分别介绍了铜在含有硫酸铵[(NH4)2SO4]、硫酸氢铵(NH4HSO4)、二氧化硫(SO2)、臭氧(O3)、氯化钠(NaCl)的大气中的腐蚀速率、腐蚀产物及腐蚀机理。表明当(NH4)2SO4微粒存在时,可能形成铜绿中的碱式硫酸铜。铜在含SO2+O3的潮湿大气中腐蚀很快,加入少量NaCl,会使腐蚀速率显著减少;加入大量NaCl,会使腐蚀速率增加。更多还原

【Abstract】 In this paper , corrosion of copper in different atmosphere is summarized.The corrosion rate,the corrosion products and the corrosion mechanism of copper in the presence of ammonium sulfate [（NH₄）₂SO₄] ,acid ammonium sulfate（NH₄HSO₄）,sulfur dioxide（SO₂） ,ozone（O₃）,sodium chloride（NaCl） are also introduced. It shows that （NH₄）₂SO₄ particles probably lead to formation of basic copper sulfates in copper patinas. The corrosion rate of copper in humid air containing a combination of SO₂ and O₃ is very rapid. Small additions of NaCl result in a marked decrease in the corrosion rate, while adding lager amounts of NaCl results in an increased corrosion rate.更多还原
