采用宏观和微观腐蚀形貌观察、失重法、X射线衍射(XRD)、电化学测试等方法,研究了紫铜在成都、雅江、理塘大气环境中暴晒 1 a的腐蚀行为.结果表明:紫铜在成都、雅江和理塘大气环境中的腐蚀程度依次降低,在大气环境暴露 1 a后生成的腐蚀产物均为Cu2 O,其中成都地区紫铜试样生成的Cu2 O含量最高,雅江次之,理塘最低.
The corrosion behavior of red copper exposed to atmospheric environment in Chengdu,Yajiang and Litang for one year was studied by means of macroscopic and microscopic corrosion morphology observation,weight loss method,X-ray diffraction(XRD)and electrochemical test.The results showed that the corrosion degree of copper in Chengdu,Yajiang and Litang atmospheric environment decreased in turn.The corrosion products generated after exposure to atmospheric environment for one year were all Cu2 O.The Cu2 O content generated on copper samples was the highest in Chengdu,the second in Yajiang,and the lowest in Litang.
