The manufacture of nanodiamonds, especially its application, has been a hot research topic for scientists from various countries in recent years.
 
Nano-diamond has been developed more than 30 years ago, but its application was limited to the field of polycrystalline, polishing agent and other abrasives. With the deepening of people’s understanding of the properties of nano-diamond, nano-diamond has been used in lubricants. , Metal coating, magnetic recording system, medicine and other fields have begun to be applied, and the application field is still expanding.
 
According to the information published by the Russian nanodiamond expert Valery Yuriyevich Dolmatov, a brief introduction to the application of nanodiamonds:
 
Adding nano-diamond to the lubricating oil can increase the working life of the engine and transmission, save fuel oil, reduce friction torque by 20-40%, and reduce friction surface wear by 30-40%.
 
After plating, the service life of the parts is increased by 1 to 9 times. The thickness of the coating can be reduced by 1 to 2 times. Standard electroplating equipment is used for electroplating.
 
Nano diamond is added to lubricating oil and coolant
 
The application of nano-diamond in lubricating oil, grease and coolant is mainly used in machinery industry, metal processing, engine manufacturing, shipbuilding, aviation, transportation. Adding nano-diamond to lubricating oil can increase the working life of engines and transmissions and save fuel. For engine oil, the friction torque is reduced by 20-40%, and the friction surface wear is reduced by 30-40%. 1000kg engine oil consumption uses 0.1~0.2kg nano-diamond. The application of nano-diamonds in lubricants must solve the problem of stable suspension. At present, companies have solved this problem.
