可信赖的浇铸铝合金牺牲阳较

Reliable cast aluminum alloy sacrifice anode

 铝合金牺牲阳较自溶性好，电流效率高，阳较发生电流的自调节性能好。适用于海水、淡水介质中的船舶、机械设备、海洋工程和海港设施以及低电阻率土壤中的管道、电缆等设施金属防腐蚀的阴较保护。

用恒电流方法测定了３种Ａｌ－Ｚｎ－Ｉｎ系合金阳较的电化学性能，用金相显微镜和扫描电镜技术（ＳＥＭ），分析了３种阳较材料的金相．结果表明：阳较晶粒越小，电流效率越高；阳较第二相数量越少，电流效率越高，但溶解不均匀；阳较的电流效率和溶解均匀性与第二相的优先溶解—脱落有关

Planning and design are unreasonable. The planning and construction of the place where the accident occurred was chaotic, and the oil and gas pipelines were too close to the surrounding buildings. In particular, the cross-engineering design of the oil pipeline and the underdrain was unreasonable. The pipelines were suspended in the drainage underdrain, and there was a risk that the crude oil leaked into the drainage underdrain, and it was not conducive to daily maintenance. Causing serious security risks.
Reasonable arrangement of the process, duration, according to local conditions to control the width of the work belt. Avoid the rainy season construction, after the completion of the operation to backfill and restore in time. Trench backfill should be stratified, and the near surface should be mixed with about 20 % of soil and certain nitrogen, phosphorus and potassium fertilizer to maintain soil fertility. When restoring the landform, we must combine the local conditions and carry out replanting of vegetation in a timely manner.
针对不同均匀化处理方式会引起合金微观和电化学性能变化现象，采用电子探针（EPMA）、动电位较化及恒电流较化等方法研究不同热处理（水淬、空冷、炉冷）方式对Al—Zn—In合金的微观和合金在3％NaCl溶液中的开路电位、工作电位、腐蚀形貌和电流效率等电化学性能的影响。结果表明：510℃，10h的均匀化处理使晶界偏析减少，舒缓析氢自腐蚀和晶粒脱落，提高电流效率，但对阳较开路电位、工作电位及溶解行为的影响并不明显，且水淬处理试样的电流效率高。

铝是一种轻金属,其化合物在天然界中分布较广,地壳中铝的含量约为8%(重量),仅次于氧和硅,具第三位。
产业纯铝（铝的含量98.0%-99.7%）。
我公司也可以根据客户的不同需求设计并出产各种特殊规格和机能的铝合金牺牲阳较。而常用铝导线的导电度约为铜的61％，导热度为银的一半。固然纯铝较软且富延展性，但仍可靠冷加工及做成合金来使它硬化。
