| Abstract: | The effect of surface treatments including anodization,Cu-electroplating,Cd-electroplating,phosphatization on galvanic corrosion of couples of titanium alloy TC2 with aluminum alloys and steels respectively in 3.5% NaCl solution was investigated for titanium alloy TC2 with different surface situation.The effects of the above mentioned surface treatments on the value of galvanic current and the variation of galvanic current with time was studied by galvanic corrosion testing.With SEM and EDS,the corrosion morphology was observed and the reasons for corrosion behavior were discussed. |
