摘要：
Zn-Mn alloys coatings are successfully electrodeposited on steel from an acidic chloride bath including organic additives, namely triton X100 and 3-hydroxybenzaldehyde (3-HBA). A homogeneous, compact, and pore-free Zn-10.1% Mn deposit is obtained at low applied current density, with faradic efficiency of 84%. The influence of triton X100 and 3-HBA on Mn content, surface morphology, structure, and texture of Zn-Mn alloys were systematically investigated. A monophasic structure composed of a single intermetallic phase epsilon-Zn-Mn (101) is observed when the Mn content exceeds 10.1%. A preferred orientation is adopted in presence of triton X100.
