Two weeks ago, Patently Apple released an IP report titled “Apple’s third patent application for future MacBooks and iDevices using a titanium base and a polymer or glass cover was released last week.” Today, the United States Patent and Trademark Office officially granted Apple a patent related to the use of titanium titled “Titanium Parts with a Blasted Surface Structure.”
The patent granted by Apple describes future devices such as a MacBook that uses a titanium substrate with a rough surface.
Apple says it may be desirable to etch the titanium while maintaining a glossy surface finish via a sandblasting process that gives the sandblasted and etched titanium part a fine-scale roughness. In this way, the sandblasted and etched titanium part is given a distinctive surface finish that reflects both diffuse and specular visible light. As a result, the sandblasted and etched titanium part is distinguished in both structure and appearance from a conventional sandblasted titanium part and a chemically etched titanium part.
The process or surface texturing of titanium alloys leads to a matte and glossy surface finish, as a glossy surface finish is generally aesthetically unsuitable for portable electronic devices in the consumer industry.
