Abstract

The disclosure relates to a textured surface for titanium parts. This application relates to an enclosure for a portable electronic device. The enclosure includes a titanium substrate having a textured surface that includes randomly distributed peaks separated from each other by valleys, where tops of the peaks are separated from bottoms of the valleys by at least a minimum separation distance such that the textured surface is characterized as having an Sq (root mean square height) that is greater than 0.3 micrometers.

Description

technical field [0001] The embodiments generally relate to techniques for etching the surface of a titanium substrate. More specifically, the embodiments relate to systems and methods for achieving a matte surface finish for titanium substrates. Background technique [0002] Portable electronic devices may include various operational components (eg, displays, processors, antennas, etc.). Housings of these portable electronic devices may be formed of various metals (eg, anodized aluminum, etc.) having high strength and rigidity to protect these operating components. Additionally, the casings are preferably treated to impart an attractive surface finish to the casings. 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 [0003] Various embodiments are ...
