在农村环境中实施了一项现场暴露计划，重点是短暴露期，并通过多分析方法详细描述最初在锌上形成的腐蚀产物层。结合沉积和气候测量的表面和整体分析研究使得确定遮蔽和未遮蔽锌板上的反应路径序列成为可能，这与所使用的所有方法一致。它涉及到两个结构相关相的形成，即羟基碳酸锌(Zn5（CO3)2(OH)6）作为初始相，羟基硫酸锌（Zn4SO4(OH)6·4H2O）作为遮蔽板的终相，(Zn5（CO3)2(OH)6）作为未遮蔽板的终相。
A field exposure program has been implemented in a rural atmosphere with emphasis on short exposure periods and detailed characterization of layers of corrosion products initially formed on zinc by means of a multi-analytical approach. Surface and bulk analytical studies in combination with deposition and climatic measurements have made it possible to identify a reaction path sequence on sheltered and unsheltered zinc panels, which is consistent with all methods used. It involves the formation of two structurally related phases, namely zinc hydroxycarbonate (Zn5(CO3)2(OH)6) as the initial phase and zinc hydroxysulfate (Zn4SO4(OH)6· 4H2O) as the final phase on sheltered panels and (Zn5(CO3)2(OH)6) as the final phase on unsheltered panels.
