Nano diamond It was first developed 30 years ago. However, its applications were limited to polishing agent, polycrystalline and other abrasives. The use of nano diamond powder in lubricating oil has increased as people have a better understanding of the properties. Applications in medicine, metal coating, magnetic record system, medicine, and many other fields have been made possible.

Traditional use areas for nano diamond powder:

1. Nano-diamonds, and metal composite coats Plated parts have a 1 to 9-time increase in service life. The coating thickness can be reduced up to 2x. Electroplating is done with standard electroplating equipment.
The average percentage of diamonds found in the metal coat is between 0.3 and 0.5% by weight. Diamond consumption is 0.02 g (one carat) when the coating thickness is 1 micron.

2. Nano diamond polishing liquid
It is widely used for semiconductor silicon wafer polishing.

The use of nano diamond powder in new development fields

1. A nano-diamond component is used as a lubricating and cooling oil.
Use of nano diamond in lubricating oils, greases, and coolants is mainly for the machine industry, metal processing. The addition of nano diamond to lubricating fluid can increase the life expectancy of engine and transmission, and help save fuel oil.

2. Nano diamond-polymer composite
Use nano-diamond polymer compounds in aviation, automobiles. tractors. shipbuilding. Medicine, chemicals. Petrochemicals. Globe valves. Protective layers. Wear-resistant coatings.

3. Sintered body
The nano-diamonds can be mixed with transition metals in order to make high-strength and very low-porosity diamond-sintered bodies. This can be used for processing soft or brittle materials, with very low surface roughness.

4. Magnetic recording system
You can also use nano-diamonds in magnetic recording devices such as magnetic tapes and magnetic disks as wear-resistant modifiers or wear-resistant additions. Nano-diamonds can be used to reduce the number of ferromagnetic materials particles, increase recording density, and reduce friction coefficient and abrasive wear.

5. Add to the intermetallic compounds
Intermetallic compounds of copper, tin and zinc containing nano diamonds are suitable for use as friction parts under very difficult working conditions. This is because plastic and liquid lubricating material are often extruded.

6. Medicine
You can also use nano diamond in medicine to treat tumors, gastrointestinal disease, and skin disorders. It is safe, non-toxic and non-carcinogenic. Nano diamond can be used as a super-active adsorbent or bioactive locator to enhance drug efficacy.
