Patent ID: 12000035

Abstract:
A part includes a base material, a colored layer on the base material, and a surface layer on the colored layer, wherein the colored layer contains Zr, and optionally, C and/or N, a ratio (HZr oxide/HZr) of a peak height derived from Zr oxide (HZr oxide) to a peak height of Zr (HZr) at an interface of the colored layer on the side of the surface layer is more than 0 and less than 4.5, the interface is a point where Zr is detected by sputtering the part from the side of the surface layer with an XPS depth direction analysis, and the ratio (HZr oxide/HZr) at a point where Ar sputtering is performed for 5 minutes from the interface of the colored layer on the side of the surface layer with the XPS depth direction analysis is 0 to less than 3. The surface layer is water-repellent and exhibits a sputtering time of 5 minutes or less.
