    Jun 30, 2021 The existence of the Sn protective layer that firmly adsorbed Zn provided an additional force to restrict the diffusion of Zn 2+. Zn 2+ was compelled to plate at the initial adsorption site, contributing to an increase in nucleation sites and a uniform surface electric field, and eventually evolving into a dense and homogeneous zinc layer. The

    Then as the piece is exposed to moisture (rainfall, dew, humidity) the zinc oxide particles react with the water to form a porous, gelatinous zinc hydroxide. Then during dry cycles, carbon dioxide reacts with the zinc hydroxide and converts to a thin, compact, and tightly adherent layer of zinc carbonate
