Form-relieved tooth and preparation method thereof
The invention aims to provide a form-relieved tooth; a carbide coating layer is arranged on the surface of a working part of the form-relieved tooth; and the invention provides a preparation method for obtaining the form-relieved tooth. The form-relieved tooth has the carbide coating layer at the front end working part. The carbide coating layer comprises a V2C compact ceramic layer, and can further comprise a micron V8C7 compact ceramic layer and a fusion layer of V8C7 and the matrix. The V2C compact ceramic layer, the micron V8C7 compact ceramic layer and the fusion layer of V8C7 and the matrix are gradiently distributed in sequence. The form-relieved tooth can be applied to the surface of low-alloy high-tensile structural steel. The coating layer and the matrix are metallurgically bonded, so that the binding force is strong, the problems of weak binding force and easy particle dropping due to traditional non-metallurgical bonding between hard particles and a metal matrix are overcome, and the wear resistance of the working surface of the form-relieved tooth is largely improved.
