鋁合金密度低，但強度比較高，接近或超過優質鋼，塑性好，可加工成各種型材，具有優良的導電性、導熱性和抗蝕性，工業上廣泛使用，使用量僅次于鋼。一些鋁合金可以采用熱處理獲得良好的機械性能、物理性能和抗腐蝕性能。硬鋁合金屬AI—Cu—Mg系，一般含有少量的Mn，可熱處理強化．其特點是硬度大，但塑性較差。超硬鋁屬Al一Cu—Mg—Zn系，可熱處理強化，是室溫下強度的鋁合金，但耐腐蝕性差，高溫軟化快。鍛鋁合金主要是Al—Zn—Mg—Si系合金，雖然加入元素種類多，但是含量少，因而具有優良的熱塑性，適宜鍛造，故又稱鍛造鋁合金。lb17184466

1) When the concentration of sulfuric acid(H2SO4) solution is high, the resulting membrane is easily colored, and the color is darker, and the membrane has a large porosity; When the concentration of sulfuric acid(H2SO4) solution is low, the color on the membrane is slow, and the color is lighter. The porosity of the membrane is relatively small. Therefore, a strong adsorption force and a flexible membrane can be used with a higher concentration of oxidation solution. If you want a hard and wear-resistant oxide film, you can use a lower concentration of oxidation liquid.
2) During anodic oxidation, the initial current density has a great influence on the structure of the oxide film. Excessive current density will cause the edge film of the sample to appear charred, and it will also cause the oxide film to be very rough. Therefore, during the anodic oxidation process, the current density should be gradually increased to a certain value, In the subsequent oxidation process, voltage fluctuations are also best not to exceed 2V. When the current density exceeds 3.3 A ? dm-2, the corrosion resistance of the oxide film decreases as the current density increases, but the current density does not exceed 3.3 A ? When dm-2, With the increase of current density, the gap rate of oxide film also increased, easy to dye, corrosion resistance is also better.lb17184466
3) Within 1 H, the growth of the oxide film is proportional to the oxidation time. However, when the oxidation time is too long, because the surface of the oxide film is dissolved by the electrolyte, the aperture of the oxide film gradually becomes larger and the film layer becomes rough.
鎂的電極電位為-2.375V
鋁的電極電位為-1.706V
鋅的電極電位為-0.763V
鐵的電極電位為-0.409V
銅的電極電位為+0.340V
鋅鋁合金的話就只能以較高的-0.763V考慮,那么如果以鋅鋁合金為犧牲陽極,那么可以用來保護鐵和銅等金屬,但不能保護鎂.
現階段主要有鎂鋁鋅三種陽極。鎂合金再用

土壤中、鋅合金用在海水中、鋁合金用在淡水中。
首先,陰極保護技術是電化學保護技術的一種,其主要原理是向被腐蝕金屬結構物表面施加一個外加電流,使得被保護結構物成為陰極,繼而讓金屬腐蝕發生的電子遷移得到抑制,避免或減弱了腐蝕的發生.
其次,就目前陰極保護技術而言,其實相對已經發展成熟,而且廣泛應用到土壤、海水、淡水、化工介質中的鋼質管道、電纜、鋼碼頭、艦船、儲罐罐底、冷卻器等金屬構筑物等的腐蝕控制.
而且,陰極保護技術有兩種：犧牲陽極陰極保護和強制電流（外加電流）陰極保護.焦作市立博輕合金股份有限公司是專業犧牲陽極、鎂合金犧牲陽極、鋁合金犧牲陽極、鋅合金犧牲陽極、
