The inhibition of dezincification of brass by benzyltriphenyl phosphonium bromide(BPB), benzotriazole(BTA) and traces of arsenic in the alloy was investigated by chronoamperometry and measurements of positron lifetime spectra in chloride solution. The results show that BPB and BTA in the solution and arsenic in the alloy can obviously decrease the transient diffusion current densities of zinc dissolution and reduce the diffusion coefficient of zinc in brass by the order of one to two. The results are interpreted in terms of the (di)vacancy diffusion mechanism.
