The following measures can be taken to improve the hardness of carbide saw blades:
- Adjust the tungsten carbide (WC) content: Tungsten carbide is one of the main components of cemented carbide. The hardness of the saw blade can be changed by adjusting its content. Typically, the higher the tungsten carbide content, the harder the saw blade will be.
- Adding alloy elements: By adding alloy elements such as titanium (Ti), tantalum (Ta), niobium (Nb), etc., the hardness of cemented carbide can be further improved. These elements can form carbides or nitrides in the alloy, thereby enhancing the hardness of the cemented carbide.
- Increase the sintering temperature: In the process of manufacturing cemented carbide, increasing the sintering temperature can promote the densification of the alloy, reduce the pores and defects in the alloy, thereby increasing its hardness.
- Increase pressure: During the sintering process, increasing pressure can further promote the densification of the alloy, thereby increasing its hardness.
- Heat treatment: Through heat treatment, the carbides or nitrides in the cemented carbide can be further dissolved or precipitated, thereby improving its hardness.
It should be noted that increasing the hardness of cemented carbide may reduce its toughness, so it is necessary to maintain good toughness while ensuring hardness. In addition, increasing the hardness of cemented carbide may also increase manufacturing difficulty and cost, so it needs to be comprehensively considered based on actual application requirements.
