Abstract

The invention relates to titanium parts with sand-blast textured surfaces. This application relates to an enclosure for a portable electronic device. The enclosure includes a titanium substrate havinga textured surface that includes peaks separated by valleys, where the textured surface is characterized as having (i) an Sdq (root mean square gradient) that is greater than 0.2 micrometers, and (ii) a gloss value that is greater than 90 gloss units as measured at 60 degrees by a gloss meter.

Description

technical field [0001] The described embodiments relate generally to techniques for forming etched titanium components. More specifically, the described embodiments relate to systems and methods for restoring the gloss finish of etched titanium parts. Background technique [0002] Portable electronic devices may include various operable components (e.g., displays, processors, antennas, etc.). The housings of these portable electronic devices can be formed from various metals (e.g., anodized aluminum, etc.) with high strength and rigidity to protect these operable components. Additionally, it is preferred to treat the enclosures, such as imparting an attractive surface finish to the enclosures. However, certain types of metals, while possessing high strength and stiffness, are also difficult to process to impart an attractive surface finish. Therefore, there is a need to implement techniques for processing these specific types of metals. Contents of the invention [000...
