通过挂片试验，电化学研究及表面分析，研究了W及 其与BTA的复合配方WB在内冷水中对发电机空芯铜导线的缓蚀作用，并与BTA的缓蚀性能进行 了对比.研究结果表明，W对铜具有较好的缓蚀作用，与BTA复配后，其缓蚀作用比W及BTA单 独使用时都强，是一种主要阻滞阳极过程的混合型缓蚀剂.
The inhibitive property of ihibitors W and WB(mixtur e 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,electr ochemical polarization and surface analysis.The inhibitive property of W and WB was c ompared 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 m ost effective for suppressing anode reaction among the inhibitors tested.The res ults of XPS showed that the corrosion inhibition of WB was due to forming a film on the surface of copper.
