ANODIZING AND PRE-ANODIZING PROCESSES BASED ON INCOMING LASER TEXTURED PART

摘要

Substrates having laser textured surfaces and methods for forming the same are described. The methods involve using a laser to form three-dimensional features on a surface of the substrate. The laser three-dimensional features can be designed to interact with incident light to create unique visual effects. In some embodiments, the substrate is further treated with a pre-anodizing process and an anodizing process to form a protective metal oxide coating. In some cases, the type of pre-anodizing and anodizing process are chosen based on the geometry of the three-dimensional features and to enhance the visual effects.

1. A method of forming on a surface, a metal oxide layer having a textured appearance, the method comprising:
forming a texture on the surface using a laser beam, the texture including three-dimensional features; modifying an appearance of the texture by increasing or decreasing a light reflectivity of the three-dimensional features; and forming the metal oxide layer on the textured surface, wherein a thickness and a transparency of the metal oxide layer is chosen based on geometries of the texture.
