Abstract

Selective corrosion resistance of the chromium implanted brass as well as vacancy formation were investigated. Dealloying was observed to create excess vacancies. Chromium and boron and many other potentially beneficial alloying elements like C, N, Si, P, V, Co, Ni, Cu, Ge, As, Y, Nb, Pd, Ag, Sn, Sb, have a repulsive interaction with vacancies and they could increase the dezincification resistance in alpha brass but not in beta brass. Boron implanted brass was found to be more resistant to selective corrosion than the chromium implanted brass.
