Abstract

The invention relates to a laser processing method for the surface of a ceramic product and the ceramic product. The laser processing method for the surface of a ceramic product comprises the following steps: cleaning the processed surface of the ceramic product; performing laser engraving on the processed surface of the ceramic product with an ultra-fast laser to obtain a pre-designed pattern: adopting a single pulse mode at 800mm / s- The marking speed is 1200mm / s for rough engraving; the multi-pulse method is used for fine engraving at the marking speed of 50mm / s-300mm / s; the wavelength of the ultra-fast laser is 1030nm-1064nm, and the pulse width is 5ps-25ps , the filling distance is 0.005mm-0.1mm, and the laser power is 10%-40%; the ceramic product is surface-treated by the above method, and the processing depth of the pattern on the processed surface of the ceramic product is 3.1um-7.8um; it can be used The processing depth reaches the micron level, making the processing depth shallower, and the surface of ceramic products feels good to the touch.

Description

technical field [0001] The invention relates to the technical field of laser engraving, in particular to a laser processing method for the surface of ceramic products and ceramic products. Background technique [0002] Laser processing, also known as laser processing. It is the process of using a high-energy-density beam to irradiate the surface of the material to vaporize the material or change its color. [0003] Ceramic materials have good mechanical and high temperature resistance properties, and have been widely used in metallurgy, chemical industry, aerospace and other industrial fields. The unique covalent bond and ionic bond structure of ceramics make them have good comprehensive mechanical properties and mechanical properties. The existing ceramic processing methods are divided into mechanical processing methods, optical processing methods, electrical processing methods, etc. according to different processing principles. [0004] Among them, the mechanical process...
