| Abstract: | In order to improve corrosion resistance of copper's alloys,a passivation solution with addition of rare earth salt is developed.The optimal process is assured through the orthogonal experiments.The corrosion resistance of samples is tested by dropping nitric acid,and its exterior appearance is observed using Scanning Electronic Microscope(SEM).The results show that rare earth salt can improve the corrosion resistance of copper's alloys corrosion inhibitor greatly.The process has low pollution and long lifetime with stable solution. |
