INHIBITIVE PROPERTY AND MECHANISM OF A NEW INHIBITOR FOR COPPER
新型铜缓蚀剂的缓蚀性能及机理探讨

The inhibitive property of ihibitors W and WB(mixture together W and BTA) for copper of the internal water cooled hollow copper wire used in generators was studied by measuring copper-content in the water,electrochemical polarization and surface analysis.The inhibitive property of W and WB was compared with benzotriazole.The results indicated that the inhibitive property of W for copper was slightly superior to BTA.Furthermore,WB was showed to be the most effective for suppressing anode reaction among the inhibitors tested.The results of XPS showed that the corrosion inhibition of WB was due to forming a film on the surface of copper.
