Core advantages in precision polishing (ultra-precision polishing):
Ultra-fine size and extreme stability: The particle size of nanodiamonds is an order of magnitude smaller than the best conventional abrasives currently available. This not only ensures the minimum surface roughness of the polished surface but also guarantees the colloidal stability of the polishing system.
Excellent surface chemistry and adsorption characteristics: Its carbon surface is highly susceptible to chemical modifications and is compatible with any polar medium, enabling nanodiamond particles to be uniformly distributed in the carrier. Additionally, its ion exchange and adsorption activity can effectively reduce the mobility of ionic and molecular products on its surface.
Reducing material loss: Using nanodiamonds can decrease the component weight of the polished surface material, thereby effectively reducing the loss of the processed materials.
Structural advantages and non-toxic environmental protection: The agglomerated structure of nanodiamond agglomerates helps regulate coalescence in suspended polishing systems, and the material itself is non-toxic.
Improving the machinability of difficult-to-machine materials: Polishing systems containing nanodiamonds can significantly improve the polishing quality of products, showing particular advantages in ensuring the machinability of difficult-to-process materials.
Core advantages in composite plating:
Excellent dispersion and strengthening effects: Solid particles in traditional composite plating films are mostly at the millimeter or micrometer scale, whereas nanodiamonds, due to their extremely fine nano-size, disperse exceptionally well in the plating solution, making their strengthening effect on the coating much more pronounced.
Super strong binding and diffusion forces: The surface of nanodiamond particles is rich in chemical functional groups such as hydroxyl, carboxyl, and carbonyl groups, which provide a very strong affinity and binding force with the plated surface (substrate). Furthermore, they exhibit high diffusion capabilities in composite plating.
Endowing coatings with outstanding physical properties: Nanodiamonds retain the inherent excellent properties of diamonds, including super hardness, high wear resistance, heat resistance, and corrosion resistance. They can effectively improve the bonding strength between the coating and the substrate, optimize the distribution of internal stress in the plating layer, and alter the direction of crack propagation, thereby protecting workpieces that are prone to failure due to contact fatigue or high-temperature wear.
Low dosage and wide applicability to substrates: In composite plating, nanodiamonds require only a very small amount to significantly improve performance. Not only can they be used for composite plating on metal surfaces, but they can also be widely applied to coatings on non-metal surfaces such as rubber, plastics, and glass.
