The tensile strength of cemented carbide is affected by many factors, including the following aspects:
- Composition and structure: The composition and structure of cemented carbide have an important impact on its tensile strength. Generally speaking, the type, particle size and distribution of carbides in the alloy, as well as the type and content of the binder, will affect its tensile strength.
- Preparation process: The preparation process also has an important impact on the tensile strength of cemented carbide, including powder preparation, sintering and heat treatment. Parameters in the preparation process such as pressure, temperature, time, etc. will affect the tensile strength of cemented carbide.
- Heat treatment: Heat treatment is an important step in the preparation process of cemented carbide. It can significantly improve the tensile strength of cemented carbide. Parameters such as heat treatment temperature, time and cooling rate will affect the tensile strength of cemented carbide.
- Surface treatment: The surface treatment of cemented carbide also has a certain impact on its tensile strength. For example, surface coating, surface hardening treatment, etc. can increase the tensile strength of cemented carbide.
- Application environment: The application environment will also affect the tensile strength of cemented carbide, such as temperature, humidity, media, etc.
In summary, to improve the tensile strength of cemented carbide, it is necessary to consider multiple aspects such as composition, structure, preparation process, heat treatment and surface treatment, and comprehensively optimize all factors to achieve the best performance indicators.
