Abstract: The embodiments described herein relate to anodic films and methods for forming anodic films. The methods described can be used to form anodic films that have a white appearance. Methods involve positioning reflective particles on or within a substrate prior to or during an anodizing process. The reflective particles are positioned within the metal oxide of the resultant anodic film but substantially outside the pores of the anodic film. The reflective particles scatter incident light giving the resultant anodic film a white appearance.

Abstract translation: 这里描述的实施例涉及阳极膜和用于形成阳极膜的方法。 所描述的方法可用于形成具有白色外观的阳极膜。 方法涉及在阳极氧化处理之前或期间将反射颗粒定位在衬底上或衬底内。 反射颗粒位于所得阳极膜的金属氧化物内，但基本上位于阳极膜的孔隙之外。 反射颗粒散射入射光，使得所得到的阳极膜呈现白色外观。
