Ceramic chisel and laser surface treatment method thereof

Abstract

This invention discloses a ceramic chopping knife and its laser surface treatment method. The method includes the following steps: molding ceramic powder into a blank using a press; sintering and solidifying; obtaining a prototype of the ceramic chopping knife; changing the roughness; ultrasonic cleaning; spin drying; designing a drawing using drawing software; importing the drawing into a laser machine; processing the ceramic chopping knife according to the drawing using the laser machine to create the desired shape; and heat treatment. This invention allows for flexible adjustment of the laser treatment depth through dot-matrix marking; compared to ordinary shapes, the dot-matrix marking adds lateral connections, forming a grid-like structure, strengthening the connectivity at each position, making it less prone to breakage under lateral forces during application, and increasing its lifespan by more than 100%; by dividing the interior and exterior into different layers, the depth and roughness of different positions can be adjusted for the application, achieving better wear resistance, lifespan, and mechanical properties for the client.
