**Abstract**
Nano-diamonds, synthesized using negative oxygen balance explosives, combine the inherent properties of diamond with unique characteristics of nanomaterials. This has drawn significant attention from engineers and technical experts, especially in exploring their potential across various technological fields. This article provides an overview of the progress and applications of nano-diamonds in different areas, highlighting their crucial role in advancing traditional technologies.
Nano-diamond is an industrial form of diamond with particle sizes typically ranging between 0.5 and 10 nm, with an average size of around 4 to 5 nm. Most particles fall within the 2 to 8 nm range. Due to their round shape, nano-diamonds possess high hardness, wear resistance, and exceptional lubrication properties. As a result, they have been successfully applied in polishing, lubrication, and plating, showing promising initial results.
**1. Ultra-fine Polishing**
Polishing is a long-established application for diamonds, and even today, it remains a critical aspect of precision manufacturing. Conventional abrasives are generally larger than 0.1 μm (100 nm), but nano-diamonds offer a much smaller particle size, making them ideal for ultra-fine polishing. Their high hardness, chemical stability, and compatibility with polar media allow for uniform dispersion in suspensions. These advantages include:
(1) Achieving minimal surface roughness and stable colloidal systems.
(2) Chemical stability allows for use with active additives.
(3) Reducing material loss during polishing.
(4) Lowering ion activity on the polished surface through adsorption.
(5) Benefiting from agglomerate structures that improve suspension control.
(6) Enhancing product quality and performance, particularly for difficult-to-machine materials.
**2. Lubrication**
Lubrication is essential for mechanical equipment, often compared to the "blood" of machines. Efficient lubrication ensures energy efficiency, long-term operation, and overall system reliability. Without proper lubrication, mechanical failure is inevitable. Studies show that friction and wear account for a significant portion of global energy loss. Nano-diamonds, due to their spherical shape, can be embedded in contact areas, creating a ball-bearing effect that reduces sliding friction and improves lubricity. Research by Kamman and Komarov demonstrates that nano-diamonds reduce wear, friction, and temperature while increasing load capacity and component life. Their effectiveness is immediate and long-lasting, making them a valuable additive in lubricants.
**3. Composite Plating with Nano-Diamonds**
Composite plating is becoming increasingly important as industries demand better surface properties. Traditional coatings often fail under extreme conditions, but nano-diamonds enhance bonding strength, stress distribution, and crack resistance. Their small size, functional groups, and strong adhesion make them ideal for metal, rubber, plastic, and glass surfaces. In China, the annual cost of metal corrosion is huge, and electroplating is a key solution. Our nano-diamond additives offer superior wear resistance at a lower cost, helping to modernize the industry and reduce environmental impact.
**4. Nano-Diamonds in Magnetic Recording Systems**
Nano-diamonds improve the performance of magnetic storage media by enhancing wear resistance and increasing recording density. They also improve the stability and longevity of magnetic heads. When combined with CoP films, nano-diamonds increase microhardness, reduce friction, and extend service life, proving their value in data storage applications.
**5. Medical Applications**
Nano-diamonds have unique properties such as high adsorption capacity, hydrophilicity, and biocompatibility, making them suitable for drug delivery, diagnostics, and treatment. They are non-toxic, non-carcinogenic, and effective against pathogens. Their ability to normalize blood pressure and support immune function highlights their potential in healthcare.
**6. Electrical Conductivity and Energy Storage**
Nano-diamonds exhibit extremely high electrical conductivity, far surpassing copper. They can be used in OLEDs, batteries, sensors, and more. Their energy storage capacity is 10,000 times greater than lithium batteries, opening new possibilities in renewable energy and advanced electronics.
**7. Renewable Energy Applications**
In thermionic energy converters, nano-diamonds enhance the efficiency of solar, geothermal, and nuclear energy conversion. The integration of carbon-14 improves performance, offering a sustainable way to manage radioactive waste.
**8. Photoluminescence**
Researchers have demonstrated photoluminescence in suspended nano-diamonds, which could lead to advanced optical sensors and quantum devices. These applications open new avenues in microchip technology and nanoscale measurement.
**9. Research and Development**
Nano-diamonds are being explored for use in extreme environments, medical implants, and quantum computing. Harvard researchers have developed nano-diamond wires that provide stable photon sources, advancing quantum communication and sensing technologies.
