The advantages of diamond coating:
1. Improved bonding strength: Diamond has a high interfacial energy with most metals, vitrified bond and even resins, resulting in poor bonding. Through the plating treatment, a layer of metal or alloy coating can be formed on the surface of the diamond, which can form a good bonding interface with the diamond and the matrix, thereby improving the bonding strength of the diamond and the substrate. This helps to reduce the shedding of the diamond during use, increasing the durability and service life of the tool.
2. Enhance the strength of diamond: There may be defects such as microcracks and microscopic voids inside the diamond crystal. During the plating process, these defects can be filled in by the coating material, which acts as reinforcement and toughening. In addition, the coating can also provide additional protection for the diamond from breaking in harsh environments such as high temperature and high pressure.
3. Improved resistance to high-temperature heat etching: In high-temperature environments, diamond is susceptible to chemical changes such as graphitization or oxidation, resulting in a decrease in its performance. When coated with a layer of metal, this metal coating protects the diamond from chemical changes at high temperatures. At the same time, the metal plating can also slow down thermal shock, protecting the diamond from damage caused by instantaneous high temperatures.
4. Optimized grinding performance: After diamond coating, its grinding performance can be optimized. On the one hand, the coating can improve the cutting efficiency and grinding efficiency of diamond; On the other hand, the coating can also reduce the wear of the diamond during the grinding process and extend its service life.
5. Increased scope of application: Diamond coating technology can be applied to different types of diamond and substrate materials, thus increasing the scope of application of diamond tools. For example, coated diamonds can be better combined with matrix materials such as metals and vitrified bond and are used to make various diamond tools.
