摘要: 采用ＩＣＰ，ＸＲＤ，ＥＭＰＡ，ＰＡＴ等方法研究了加硼对铝黄铜脱锌行为的影响和机理。结果表明，在铝黄铜中加入微量硼，能提高合金抵抗这类选择性腐蚀的能力；硼能填充铝黄铜中的双空位，减缓锌的溶解速率；硼与砷的协同作用，可以几乎完全抑制脱锌腐蚀。文中指出了铝黄铜中硼的最佳含量。

Abstract：The role of boron in inhibiting dezincification of aluminium brass was investigated by ICP, XRD,EMPA and PAT methods. By adding trace boron into aluminium brass with or without arsenic, the resistance of the brass against this type of selective corrosion could be remarkably improved. Due to the synergetic effect of boron and arsenic, dezincification was hindered. The optimum content of boron in the alloy was about 0.01% in the absence of arsenic, and 0.005~0.008% in the presence of arsenic.For aluminium brass without boron and arsenic, dezincification was attributed to the diction of grain boundary because of its large grain size. For aluminium brass with boron but without arsenic, boron could move into the grain boundary and divacancy, wich were considered to be the route of dezincification, and then reduced the dezincification rate. In the presence of boron and arsenic in brass, boron and arsenic atoms moved into the divacancy, blocked the way of dezincification, so that dezincification could not take place.

Key words： Boron Brass Dezincification
