This study was aim to qualitatively and quantitatively clarify the relation between formation, structure and morphology of artificial zinc rusts and density, reactivity, stability of zinc rusts on galvanized steel. The details were summarized as follows.(1) Among various atmospheric corrosive gasses SO_x is the most effective corrosive gas on the formation of zinc rusts of basic zinc salt (BZS) on galvanized steel to form zinc hydroxysulfate rust.(2) Adding the Ti(IV) inhibited the crystallization, particle growth and adsorption of corrosive gasses such as H_2O and CO_2 of zinc rust of BZS.(3) At later stage of corrosion of galvanized steel, formation, particle morphology and adsorption of corrosive gases of zinc rust BZS strongly were strongly influenced by Fe(III) eluted from steel and those of steel rust ?-FeOOH were considerably effected by zinc rust particles.

本研究旨在定性和定量地阐明人造锌锈的形成、结构和形貌与镀锌钢上锌锈的密度、反应性和稳定性之间的关系。具体内容概括如下：(1)在各种大气腐蚀气体中，SO_x是对镀锌钢上碱式锌盐(BZS)的锌锈形成羟基硫酸锌锈最有效的腐蚀气体。(2)添加Ti (四)抑制BZS锌锈的结晶、颗粒生长和对H_2O、CO_2等腐蚀性气体的吸附。(3)锌锈腐蚀后期在镀锌钢中，锌锈BZS的形成、颗粒形貌和对腐蚀性气体的吸附受钢中析出的Fe(III)的强烈影响，而钢锈α-FeO​​OH则受锌锈颗粒的显着影响。
