cathodic current density
解釋
陰極電淋度-
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。 -
Based on some discussions on the mathematic model set up for the cathodic protection potential field, a two - dimensional boundary element method ( bem ) is developed, and by using which, a study on the shielding effect resulted from some typical inner structures such as the reinforcing elements and the partition walls with man holes on distribution of potential and current density in the cathodic protection is performed. the investigated parameters which affect the shielding effect in the calculating model include : the height and thickness of the reinforcing elements, the distance between the anode and the reinforcing elements, and the diameter of man hole on the partition walls, and so on
本文在討論了陰極保護電位場問題的數學模型的基礎上，以二維邊界元法對陰極保護問題中的電位及電流密度分佈進行了模擬計算，重點對船舶壓載艙中的典型結構如加強筋、人孔等在陰極保護中所產生的屏蔽效應進行了分析和研究，通過對不同高度、厚度的擋板及不同孔徑的帶孔板所產生的屏蔽效應進行模擬計算，首次得到了一些對實際工程設計具有重要參考意義的見解。 -
The hardness and corrosion resistance were evaluated by, the anticorrosion mechanism was also discussed by xps as well. the composited content of particles in coating was high when 0. 5 % super - 3900 was added into al2o3 suspention before plating the composited content increased with the increase of al2o3 concentration in plating solution and the time of stirring before plating and increased as a peak curve with plating temperature, cathodic current density and ph value
超分散劑super - 3900加入量為0 . 5 % ，對al2o3懸浮液分散后加入時，獲得的鍍層復合al2o3含量高，並隨著鍍液中al2o3含量、鍍前攪拌時間增加而增加，鍍層中al2o3含量隨著施鍍溫度、陰極電流密度、 ph值的增加呈先增加后減少的變化。
