Abstract
Official abstract text for this publication.
This application relates to an enclosure for a portable electronic device. The enclosure includes a titanium substrate having a 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.
First claim
Opening claim text (preview).
What is claimed is: 1. An enclosure for a portable electronic device, the enclosure comprising: a titanium substrate defining a textured surface having an Sdq (root mean square gradient) that is greater than 0.2 micrometers, and a gloss value that is greater than 90 gloss units as measured at 60 degrees by a gloss meter. 2. The enclosure of claim 1 , wherein the textured surface comprises peaks separated by valleys, a separation distance between apexes of the peaks and troughs of the valleys being at least 2 micrometers. 3. The enclosure of claim 1 , wherein the textured surface has a gloss value that is greater than 20 gloss units as measured at 20 degrees by the gloss meter. 4. The enclosure of claim 1 , wherein the textured surface has a gloss value that is greater than 70 gloss units as measured at 85 degrees by the gloss meter. 5. The enclosure of claim 1 , wherein the textured surface has an Sq (root mean square height) that is greater than 0.2 micrometers. 6. The enclosure of claim 1 , further comprising an anodized layer overlaying a portion of the textured surface and having a thickness between 20 nanometers to 200 nanometers. 7. The enclosure of claim 1 , wherein the titanium substrate is a welded titanium part.
