Application Of Nanodiamond In Magnetic Recording System

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.
 
Magnetic recording system
 
Nanodiamonds can also be used in magnetic recording media such as magnetic tapes and magnetic disks, acting as wear-resistant additives and physical modifiers. Nanodiamonds are added when electrochemically coating composite magnetic recording films to improve the performance of magnetic recording devices. Add nano Diamond can reduce ferromagnetic material particles, increase recording density, reduce abrasive wear and friction coefficient.
 
Add to intermetallic compound
 
Copper, tin, and zinc intermetallic compounds containing nanodiamonds can be used as friction parts under very harsh working conditions. At this time, plastic and liquid lubricating materials are often extruded. Nanodiamonds are ideal component materials for copper-zinc or copper-tin alloys ( The content does not exceed 15% by volume). After adding nano diamond, the friction is reduced to 1/2~1/6.
 
Medicine
 
Nanodiamonds can also be used in medicine to treat tumors, gastrointestinal diseases, and skin diseases. It is non-toxic, non-carcinogenic or rusty. Nanodiamonds are super active adsorbents and bioactive substances locating agents, which can greatly enhance drugs efficacy.
