70-30α黄铜被广泛地运用在发电厂和船舶上作为冷凝管材料,可是在使用过程中常出现黄铜脱锌现象——一种特殊腐蚀破坏,而严重地影响到设备的正常运转。据报导,含有0.03％砷的α黄铜会有效地抑制脱锌。尽管前人努力探讨过黄铜中砷的作用,但是正象文献所述的,它的作用方式目前仍旧不够清楚。最近作者研究了黄铜阴极上铜的再沉积效率和腐蚀后介貭的Cu/Zn比值等的结果,初步弄清楚了砷对腐蚀量(总的和个别的) 70-30α brass is widely used in power plants and ships as condenser materials. However, the dezincification of brass often occurs during use - a kind of special corrosion damage, which seriously affects the normal operation of the equipment. It has been reported that alpha brass containing 0.03% arsenic effectively inhibits dezincification. Although previous efforts have been made to explore the role of arsenic in brass, as it has been described in the literature, its mode of action remains unclear. Recently, the author studied the results of redepositing efficiency of copper on brass cathode and Cu / Zn ratio of intercalation after corrosion, and made a preliminary clear understanding of the effect of arsenic on corrosion (total and individual)
