Abstract

The invention relates to nitrided titanium surfaces with a natural titanium color. This application relates to an enclosure for a portable electronic device. The enclosure includes a titanium substrate having interstitial nitrogen atoms, where the titanium substrate is characterized as having an a* value that is less than 1, a b* value that is less than 5, and an L* value that is more than 70.

Description

technical field [0001] The embodiments generally relate to titanium components having an outer surface hardened by nitriding. More specifically, the embodiments relate to methods for forming titanium nitride parts having a natural titanium color. Background technique [0002] Housings for portable electronic devices can be made from a variety of different materials. In some cases, the housing can be made of titanium. However, in the field of consumer electronics where there is a greater need for wear resistance, titanium and its alloys may not be sufficient to provide sufficient hardness and strength to protect the operating parts carried by these housings. While titanium and its alloys are capable of undergoing a "face hardening" process, the resulting titanium nitride is characterized as having a distinct gold / brown color that is unattractive to many consumers. Contents of the invention [0003] Various embodiments are described herein that relate generally to titaniu...
