In this investigation, the influence of surfactant in chromating in zinc-nickel alloy electroplating through use of sulfate solutions has been examined.
Results indicate that the eutectic amount of nickel in the surface layer of the deposit decreased with the addition of dodecyltrimethyl-ammonium chloride (DTAC). Therefore, the formation of chromate films became possible for this deposit and corrosion resistance with respect to white rust improved remarkably.
