Figure 10: FIB cross section of black passivated zinc–nickel with the final formulation of the trivalent chromium post-dip solution (Tridur Finish 300 10% v/v, pH 5.5, 45°C). Figure 13: SEM micrograph of black passivated Zn/Ni alloy (Tridur ZnNi H1) with post-dip applied (Tridur Finish 300, 10% v/v, pH 5.5, 45°C, drying temperature of 80°C). Figure 11: SEM micrograph of black passivated Zn/Ni alloy (Tridur ZnNi H1) without any further post- treatment.
