At present, film photocatalytic is studied mostly for treating with water pollution. Because the film will not bring the secondary pollution, and can be used again. ZnO film and TiO_2 film is mostly used as photocatalyzer, but they have some disadvantage, as they can only absorb little of the sun-light energy, the photoluminescence exciton compounds mostly, and they can be eroded easily by light. Complex semiconductor film is a good method to ravel out these problems.

目前，在光催化治理水污染方面，膜的光催化是一个研究的热点，因为膜催化不存在二次污染且便于回收和重复利用，研究较多的是ZnO薄膜和TiO_2薄膜，但是单一组分的薄膜存在光能利用率低，光激子复合率高，易发生光腐蚀等缺点，复合膜是解决该问题的有效途径，我们提出了全新的复合薄膜的制备方法—混合溶胶法。

Heat sintered ZrO_2 ceramic does not react with any acids and bases except HF. It can't be coarsened by the traditional pretreatment process. Through a great deal of experiments, author found a kind of coarsened prescription which can corrode ZrO_2 ceramic, forming many holes and troughs on its surface.

On the basis of atmospheric corrosion analysis and on the premise of unaltered originappearance of metal antiquity, a novel systematic technology of rust stabilized conversion and corrosioninhibition for archeological iron was developed in this thesis. Model occulted corrosion cell was used to studythe formation of bronze powder rust, its characteristics of pit corrosion and effect factors. The filmingtreatment of azoles composite corrosion inhibitors was used to prevent silver tarnishing, and its anti-tarnishingmechanism was proposed by measurement of electrochemical techniques and Surface-enhanced Ramanscattering.

In the coating, the nodular defect was observed to worsen severely the properties. For testing under oxidation condition, the nodular defect results in the internal oxidation of Al. No single Al oxide scale may be formed at 1100℃ owing to consumption of Al. Under hot corrosion, it becomes as short-path for diffusion of S through the coating, thus sulphuring the coating together with the substrate. During thermal shock testing, it may act as the source of cracking, and moreover, if cyclic stress applied, the cracks propagate toward the substrate, the thermal fatigue properties of coating will be worsened.

结果表明：在氧化条件下，缺陷导致Al的内氧化，在1100℃时，由于Al的大量内消耗，涂层表面已不能形成单一的氧化铝膜，使氧化性能下降；在热腐蚀条件下，缺陷成为硫向涂层中扩散的通道，导致涂层及基体的硫化；在冷热疲劳条件下，缺陷成为裂纹源，在交变应力作用下，裂纹向基体中扩展，降低了涂层的热疲劳性能。

In the case of decorative zinc electroplatings, a further enhancement of the appearance of such substrates in addition to the corrosion resistance imparted is achieved by the passivate film which ranges from a clear bright to a light blue bright appearance simulating that of a chromium deposit or alternatively, a clear light-yellow appearance simulating that obtained by use of prior art hexavalent chromium solutions.
