摘　　要：采用原子层沉积技术实现了膜层厚度均匀性小于3.5%的银饰TiO_2保护薄膜的制备。X射线衍射测试结果表明,沉积温度为100℃时薄膜为无定型结构,沉积温度为250℃时薄膜为锐钛矿相。腐蚀实验结果表明,30nm和45nm厚度的TiO_2薄膜都具一定的抗变色能力,但厚度为45nm的TiO_2薄膜的抗变色能力更佳。光谱测试结果表明,在不影响银饰外观的前提下,单层TiO_2作为保护膜的抗变色效果无法达到最佳。Using the atomic layer deposition technology, the fabrication of TiO2 thin protecting film on silver ornaments with a thickness uniformity less than 3.5% is realized. The X-ray diffraction test results show that the structure of TiO2 thin film is amorphous structure at the deposition temperature of 100 ℃, while the thin film presents anatase phase at the deposition temperature of 250 ℃. The corrosion experiment results show that the TiO2 thin films with the thickness of 30 nm and 45 nm both have the anti-tarnishing ability, while the ability of the latter is better. The spectrum test results show that, under the condition that the appearance of silver ornaments is not affected, the single layer of TiO2 as protecting film is insufficient to achieve the best anti-tarnishing effect.
