Abstract

The disclosure relates to a black zirconia ceramic, a black zirconia ceramic shell and a preparation method thereof. A method for preparing black zirconia ceramics, comprising: providing a black zirconia ceramic substrate; preparing and forming an ion implantation layer on the first surface of the black zirconia ceramic substrate; preparing and forming an optical coating layer on the surface of the ion implantation layer to improve black The transmittance of the zirconia ceramic substrate in the visible light range is obtained to obtain black zirconia ceramics. In the present disclosure, by preparing an ion implantation layer on the surface of the black zirconia ceramic, the surface of the black zirconia ceramic can be strengthened, and an optical coating layer can be formed on the surface of the ion implantation layer, which can change the reflection and transmission characteristics of the black zirconia ceramic surface. Weaken or eliminate the gray-yellow phase of black zirconia ceramics, beautify the appearance of black zirconia ceramics, improve the transmittance of black zirconia ceramics in the visible light range, and improve the appearance and texture of black zirconia ceramics.

Description

technical field [0001] The disclosure relates to the technical field of shell processing, in particular to a black zirconia ceramic, a black zirconia ceramic shell and a preparation method thereof. Background technique [0002] Zirconia ceramics are a new type of ceramic material with many excellent properties such as wear resistance, corrosion resistance, high strength, high toughness, and good thermal stability. Compared with metals and plastics, zirconia ceramics have the characteristics of high Mohs hardness, high dielectric constant, no signal shielding and good biocompatibility, and have broad application prospects in smartphones and wearable devices, which makes zirconia Zirconium ceramics start from fingerprint identification cover and mobile phone back cover, and will gradually cut into the mobile terminal industry chain, becoming the third largest mobile phone back panel material after plastic and metal. [0003] Zirconia powder itself is a white powder, and the c...
