抗海水腐蚀减摩和抗生物污损的复合涂层及其制备方法
摘要：
本发明是一种抗海水腐蚀减摩和抗生物污损的复合涂层及其制备方法。该复合涂层包括粘接底层、复合陶瓷涂层和表面封孔层，其中：粘接底层采用超音速火焰喷涂ZnNi合金粉末在金属基材上；复合陶瓷涂层采用等离子喷涂抗生物污损和抗海水腐蚀的复合陶瓷粉末在粘接底层上；表面封孔层采用低表面能的无机或有机封孔剂，涂覆在复合陶瓷涂层的表面上；按质量百分比计，复合陶瓷涂层组分由氧化物基相陶瓷粉末80～95％和抗生物污损粉末材料5～20％组成；抗生物污损成分为Cu、CuO或Cu2O粉；采用Cu粉时，应在粘接底层与导电的复合陶瓷涂层之间再加喷一层绝缘陶瓷过渡层。该复合涂层的制备简单、制造成本低和适于工业化生产等优点。
摘要（英）：

A composite coating against biological fouling and seawater corrosion and its production are disclosed. The composition consists of oxide based-phase ceramic powder 80-95 wt% and powder against biological fouling 5-20 wt% with Cu, CuO or Cu2O powders. The composite coating comprises binding bottom layer, composite ceramic coating and surface sealing layer; ZnNi alloy powder is sprayed on metal substrate of binding bottom layer by supersonic flame; Composite ceramic power against biological fouling and sea-water corrosion is sprayed on bottom of composite ceramic coating by plasma; Inorganic or organic sealer with low surface energy is sprayed on surface sealing layer. An insulating ceramic transient layer is added between binding bottom layer and composite ceramic coating when Cu powder is adopted. It's simple and cheap and can be used for industrial production.
