摘要:
The present disclosure provides a metal based dental article and a method of forming the metal based dental article. The metal based dental article includes a base layer, a first coating on the base layer and a second coating on the first coating. The base layer is formed from a metal substrate selected from the group consisting of a stainless steel, a titanium alloy or a nickel titanium alloy. The first coating is formed from a metal selected from the group consisting of nickel, a nickel alloy, copper, a copper alloy, zinc, a zinc alloy, tin, a tin alloy, gold or a gold alloy, where one of the first coating or the surface of the base layer has a surface roughness (R a ) from 0.1 to 1.0 microns as measured according to ASTM B46.1-2009. The second coating is formed from a metal selected from the group consisting of rhodium, a rhodium alloy, ruthenium, a ruthenium alloy, cobalt, a cobalt alloy, palladium, or a palladium alloy. The second coating has a predetermined thickness that provides the metal based dental article with a matte finish and a whiteness, L*, of at least 80 of the CIELAB color system (L*, a*, B*).
摘要(中):
本公开提供了一种金属基牙科用品和形成金属基牙科用品的方法。 金属基牙科制品包括基底层,基底层上的第一涂层和第一涂层上的第二涂层。 基层由选自不锈钢,钛合金或镍钛合金的金属基材形成。 第一涂层由选自镍,镍合金,铜,铜合金,锌,锌合金,锡,锡合金,金或金合金的金属形成,其中第一涂层 或者根据ASTM B46.1-2009测量,基底层的表面具有0.1至1.0微米的表面粗糙度(Ra)。 第二涂层由选自铑,铑合金,钌,钌合金,钴,钴合金,钯或钯合金的金属形成。 第二涂层具有预定厚度,其为金属基牙科制品提供了CIELAB颜色系统(L *,a *,B *)的至少80的无光泽度和白度L *。
