時間-密度曲線-
The corrosion potential was the biggest and the corrosion current was the smallest one when the concentration of super - 3900 was 0. 5 % ; the corrosion potential was increased with the addition of mps - dl, but the smallest corrosion current is under 0. 01 % mps - dl. the rust time was the longest one when the concentration of super - 3900 was 0. 5 % as well as mps - dl was 0. 01 %. it was increased as a peak curve with al2o3 concentration in plating solution and ph value increased gradually with cathodic current density ; the corrosion weight
通過測量tafel曲線可知，在super - 3900濃度為0 . 5 % （相對于鍍液的體積百分含量）時獲得的鍍層腐蝕電位最正，腐蝕電流密度最小;隨著鍍液中mps - dl含量的增加，獲得的鍍層的腐蝕電位逐漸正移，在濃度為0 . 01 % （相對于鍍液的體積百分含量）時腐蝕電流密度最小。 -
