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

金属目前广泛用于牙科，但由于其颜色，它具有美学缺点。为了达到牙科金属增白的目的，采用微波等离子体CVD（Chemical Vapor Deposition）沉积技术，在纯钛、牙科金合金和纯铂表面制备了金红石型TiO2薄膜。在成膜条件上观察到一些差异，在纯钛和纯铂上的膜颜色为白色至灰白色。在银组分的影响下，金合金表面的膜层颜色为灰白色。在所有样品中，粘合强度都不够。今后的任务是研究获得良好粘合强度的条件。

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.
