The thermal stability of diamond abrasive refers to its stability and heat resistance under high temperature conditions.
It is crucial for its performance in various applications, especially in high-temperature environments such as manufacturing sawing tools, grinding tools, cutting tools, and geological drill bits. These applications require diamond to have high strength, hardness, heat resistance, and chemical inertness. The thermal stability of diamond is not only related to its own physical and chemical properties, but also directly affects the performance and lifespan of the tool.
The thermal stability of diamond abrasive is influenced by various factors, including its internal impurity content, defects, and external environmental factors such as atmospheric environment and contact medium. For example, in air,diamond gradually transforms into graphite from 800 ℃, which reduces its hardness and affects its performance. In addition, the thermal stability of diamond is also affected by additives, such as boron, which can delay the oxidation process of diamond, improve its surface oxidation resistance, and enhance its thermal stability.
Studying the thermal stability of diamond abrasive is of great significance for improving the performance of diamond tools.
Through research and application, products with better thermal stability can be developed, improving the performance and lifespan of tools, reducing production costs, and thus increasing production efficiency. For example, by adding additives such as boron, the antioxidant capacity of diamond can be improved, its oxidation rate at high temperatures can be slowed down, and its thermal stability can be enhanced.
