The purity of diamond micro-powder has a significant impact on the processing effect, which is specifically reflected in the following aspects:
1. Impact on processing accuracy and surface quality: High-purity diamond micro-powder has a low impurity content and will not introduce additional impurities during the processing, thus avoiding contamination and scratches on the processed surface. For instance, during the manufacturing process of semiconductor chips, if the purity of diamond micro-powder is insufficient, even trace impurities may cause damage to the microstructure on the chip surface, affecting the performance and accuracy of the chip. High-purity diamond micro-powder can ensure the flatness and smoothness of the processed surface and improve the processing quality.
2. Affecting the durability of processing tools: Diamond micro-powder with high impurity content will reduce its overall hardness, affecting the performance of deep processing tools. During the processing, these impurities may accelerate the wear of the tools and shorten their service life. High-purity diamond micro-powder, on the other hand, features higher hardness and wear resistance, which can extend the service life of tools and reduce processing costs.
3. Impact on processing efficiency: High-purity diamond micro-powder can maintain stable cutting performance during the processing, reducing the fluctuation of cutting force and processing instability caused by impurities. This is conducive to improving processing efficiency and shortening processing time.
4. Affecting coating performance: In coating technology, the purity of diamond micro-powder is also of vital importance. High-purity diamond micro-powder can better combine with the coating substrate to form a uniform and dense coating structure. This coating has better wear resistance, corrosion resistance and thermal conductivity, which can significantly improve the performance and service life of coated tools.
