Preparation of Titania Coating on Dental metals by Microwave Plasma CVD -In Search of White Metal-

金属目前在牙科中被广泛使用，但由于它的颜色，它有一个美学上的劣势。采用微波等离子体化学气相沉积(CVD)沉积技术，在纯钛、牙科金合金和纯铂表面制备了金红石型氧化钛薄膜。成膜条件有所不同，纯钛和纯铂的成膜颜色为白色到灰白色。在银组分的影响下，金合金表面的膜层呈灰白色。在所有的样品中，粘接强度都不够。下一步的任务是研究获得良好粘接强度的条件。

Metal is currently widely used in dentistry, but it has an aesthetic disadvantage because of its color. For the purpose of whitening of dental metal, titania film were prepared on a pure titanium, a dental gold alloy, and a pure platium, by applying a microwave plasma CVD (Chemical Vapor Deposition) deposition technique.Titania film produced was a rutile type at any metal. Some differences were observed in the film forming conditions, the films color on the pure titanium and the pure platinum were white to grayish white. Under the influence of the silver component, the films color on the gold alloy were grayish white. In all of the samples, the adhesive strengths were not enough. The future tasks are to examine the conditions for obtaining the good adhesive strength.
