- 摘要:
- 利用提拉法在紫铜基体上制备了ZnO涂层，并研究了成膜添加剂及水热加强过程对其机械性能及耐腐蚀性能的影响。研究表明，在ZnO溶胶液中加入成膜添加剂可使ZnO涂层形成大量直径为300 nm左右的孔洞，大幅提高了涂层的比表面积、附着力、硬度和耐磨性能；进一步的水热处理过程可在纳米多孔ZnO涂层之上生长一层粒径为100 nm左右的ZnO颗粒，进一步提高了涂层的比表面积，同时附着力明显提升，而硬度、耐磨性能基本保持不变；阳极氧化测试及交流阻抗测试表明，添加剂的加入及后续进行的水热加强处理能提高ZnO涂层的耐腐蚀性能。
- Abstract:
- The Zinc oxide （ZnO） coating was prepared on the copper substrate by the dipping-coating method, and effects of the film-forming additives and hydrothermal enhancementprocess on its mechanical properties and corrosion resistance were studied. Investigations have shown that the addition of film-forming additives to the ZnO sol solution can form a large number of holes with a diameter about 300 nm on the ZnO coating, greatly increase the specific surface area and improve the adhesion, hardness and wear resistance of the coating. Further hydrothermal treatment process can grow a layer of ZnO particles with a diameter about 100 nm on the top of nano-scale porous coating, which further improves the specific surface area of the coating, and significantly improves the adhesion, while the hardness and wear resistance remain unchanged.Anodizing test and AC impedance test demonstrate that the addition of additives and the subsequent hydrothermal enhancement treatment can improve the corrosion resistance of the coating.
