Embodiment 1

[0032] figure 1 It is a flow chart of a ceramic surface treatment method shown according to an exemplary embodiment, and the method can be applied to ceramic shells and the like. Such as figure 1 As shown, the method includes the following steps.

[0033] In step S11, the texture is made on the surface of the ceramic by means of laser laser. Among them, making textures by laser laser is also called "laser laser engraving" or "laser laser engraving".

[0034] In a possible implementation manner, the ceramics may be zirconia ceramics, or other suitable ceramic materials with similar properties, which are not limited herein. For ease of understanding, zirconia ceramics are taken as an example for illustration below.

[0035] In a possible implementation manner, the method may further include preparing zirconia ceramics, for example, making powder into zirconia ceramics by means of dry pressing, hot die casting, sintering and the like.

[0036] figure 2 is a schematic diagr...

Embodiment 2

[0060] Figure 12 It is a schematic diagram of a ceramic shell according to an exemplary embodiment. The ceramic shell is surface-treated by the above-mentioned method, as shown in FIG. 11 , the shell can be used for mobile phones or other devices, such , tablets, watches, etc.

Abstract

The invention relates to a ceramic surface treatment method and a ceramic casing. The method comprises steps as follows: texture is manufactured on the surface of ceramic in a laser manner; annealing treatment is performed on the ceramic to enable the texture to have a first predetermined color. The texture manufactured on the surface of the ceramic through laser is subjected to annealing treatment, the achievable color range of the manufactured texture effect on the ceramic can be enlarged, burning traces formed after laser are eliminated, the texture color of a manufactured product keeps stable and does not change or shed off, and the surface is smooth. The provided method adopts concise procedures, is high in production efficiency and can effectively reduce the cost.

Description

technical field [0001] The present disclosure relates to the technical field of ceramic materials, in particular to a ceramic surface treatment method and a ceramic shell. Background technique [0002] With the continuous development of material technology, more and more new materials are used in the production of product shells. Zirconia ceramics is a representative of these new materials. During the research and development and production of zirconia ceramics, the problems of surface decoration and effect optimization are constantly encountered. [0003] In related technologies, due to the compactness and hardness of zirconia ceramics, it is difficult to produce texture effects such as good durability, wide color range, and smooth surface on the surface of zirconia ceramics using traditional laser engraving or printing processes. Contents of the invention [0004] In order to overcome the problems existing in related technologies, the present disclosure provides a ceram...
