There are many potential causes of corrosion in animal buildings. Animals exhale large quantities of moisture into the air creating high relative humidity in the building if the moisture is not properly vented. High humidity increases the potential for condensation. In addition, ammonia may be found in large quantities in animal buildings. Ammonia is released from manure and urine. In addition, ammonium chloride is used as a nitrogen source in fertilisers. In this study, the atmospheric corrosion of hot‐dip‐galvanised steel and zinc alloy‐coated steel such as zinc–aluminium and zinc–aluminium–magnesium has been studied in atmospheres containing different levels of ammonia. Investigations have also been conducted at different levels of ammonium chloride. The results are discussed in view of the mechanisms of corrosion of zinc and zinc alloy‐coated steel in ammonia and ammonium chloride‐containing environments.

热浸镀锌钢和镀锌合金的钢在氨和氯化铵中的腐蚀

动物建筑物中有许多潜在的腐蚀原因。如果没有适当地排出水分，动物会向空气中呼入大量水分，从而在建筑物内产生较高的相对湿度。高湿度会增加冷凝的可能性。另外，在动物建筑物中会大量发现氨。氨从粪便和尿液中释放出来。另外，氯化铵被用作肥料中的氮源。在这项研究中，已经研究了在氨水含量不同的环境下对热浸镀锌钢和锌合金涂层钢（如锌铝和锌铝镁镁）的大气腐蚀。还对不同含量的氯化铵进行了研究。
