Common surface treatment methods for cemented carbide products include:
- Mechanical polishing: A polishing method that uses cutting to remove the protruding parts after polishing to obtain a smooth surface. Xidi Company mainly uses mechanical polishing method to polish cemented carbide parts to meet the surface roughness standards required by customers. Mechanical polishing generally uses tools such as oilstone strips and grinding wheels, and is mainly manual operation, which requires high technical requirements for operators. For surface polishing of special parts such as rotary bodies, auxiliary tools such as turntables can be used. For those with high surface quality requirements, ultra-precision grinding and polishing can be used.
- Chemical gold plating: By plating a metal film on the surface of cemented carbide to improve its corrosion resistance and wear resistance, it can also make the surface of cemented carbide more beautiful. Commonly used metals include chromium, nickel, copper, etc. The advantage of electroless gold plating is that it can be plated on irregularly shaped surfaces without affecting the size of the cemented carbide. However, the disadvantages are also obvious. This treatment method is time-consuming, complex, and involves some environmental issues.
The above are the common surface treatment methods for cemented carbide products.
