The cemented carbide manufacturing process has an important impact on the performance of the product. Here are some of the main factors:
- Selection and preparation of raw materials: The main components of cemented carbide are carbides and metal binders. The type, particle size, and content of carbides, as well as the type and amount of metal binders, will affect the performance of the final product.
- Synthesis and sintering process: Synthesis and sintering process are key steps in the cemented carbide manufacturing process. The selection and execution of process parameters will have an important impact on the structure and performance of the product. For example, synthesis temperature, pressure, time and sintering temperature, time and atmosphere will affect the grain size and distribution of cemented carbide and the density, hardness, strength and other properties of the alloy.
- Heat treatment process: Heat treatment process can change the microstructure and mechanical properties of cemented carbide, such as hardness, strength, toughness, etc. Through appropriate heat treatment, the balance between hardness and toughness, impact resistance and wear resistance of carbide can be optimized.
- Surface treatment: The surface treatment of cemented carbide products can change its surface state, thus affecting its performance. For example, surface coatings can improve the corrosion and wear resistance of carbide, thereby increasing its service life.
In short, every step in the cemented carbide manufacturing process has an impact on the performance of the product. Therefore, various process parameters need to be strictly controlled during the manufacturing process to ensure that the performance of the final product meets the requirements.
