Abstract

The present disclosure provides an anodized part with a matte black appearance. The anodized part includes a metal substrate and an anodized layer covering and formed from the metal substrate. The anodized layer includes: (i) an outer surface comprising randomly distributed light absorbing features capable of absorbing visible light incident on the outer surface; and (ii) pores defined by pore walls into which color particles are injected. inside the hole. The anodized layer is characterized as having a color with an L* value of less than 10 using the CIE L*a*b* color space.

Description

[0001] Cross References to Related Applications [0002] This disclosure claims priority to US Provisional Patent Application 62 / 853,629, filed May 28, 2019, entitled "ANODIZED PARTHAVING A MATTE BLACK APPEARANCE," the entire disclosure of which is hereby incorporated by reference. technical field [0003] The embodiments generally relate to etching the surface of a dyed anodized part. More specifically, the described embodiments relate to techniques for etching the surface of a dyed anodized part to form light absorbing features capable of absorbing substantially all visible light incident on the exterior surface to impart a black appearance. Background technique [0004] Housings for portable electronic devices may include anodized layers that may be tinted in different colors in order to enhance their visual appeal to consumers. However, some colors are much more difficult to achieve than others. In particular, attempts by consumer electronics device manufacturers to a...
