This work aimed to study the effect of surface properties on the corrosion resistance and cleanability of glazed surface. The samples were zircon‐containing raw glaze, zirconium‐based frit glaze, double‐glazed transparent glaze, and raw glaze coated with TiO₂ film. The corrosion resistance of the samples in acidic, alkaline, and household detergent solutions was investigated by the changes in contact angle and surface roughness. Besides, the cleanability of the samples before and after corrosion was also compared. It was found that the corrosion resistance of a glaze was affected by the presence of crystals and their distribution, while the corrosion resistance of TiO₂ film was closely related to itself and the nature of the substrate. The cleaning test showed that although adding a layer of transparent glaze reduced the surface roughness, it did not improve the cleanability. The TiO₂ film had excellent cleaning performance, especially after ultraviolet light irradiation, but it had weak alkali corrosion resistance. Therefore, a zirconium‐based frit glaze is the right choice for sanitary ware in terms of durability and easy cleaning.

釉面的耐腐蚀性和清洁性

这项工作旨在研究表面性质对釉面的耐腐蚀性和清洁性的影响。样品为含锆的生釉，锆基玻璃料釉，双层釉透明釉和涂有TiO ₂薄膜的生釉。通过接触角和表面粗糙度的变化研究了样品在酸性，碱性和家用洗涤剂溶液中的耐腐蚀性。此外，还比较了腐蚀前后样品的清洁度。发现釉的耐蚀性受晶体的存在及其分布的影响，而TiO ₂的耐蚀性薄膜本身与基材的性质密切相关。清洁测试表明，尽管添加一层透明釉可降低表面粗糙度，但并不能改善清洁性。TiO ₂膜具有优异的清洁性能，尤其是在紫外线照射后，但其耐碱性腐蚀性能较弱。因此，就耐用性和易清洁性而言，锆基玻璃料釉是卫生洁具的正确选择。
