Lubricating Materials Nano Polycrystalline Diamond Powders 

Application for nano polycrystalline diamond powders:

1. In boundary lubrication, base oil and lubricant dispersed nano-diamond solid two-phase composition in the oil lubricant with excellent carrying capacity and anti-wear, anti-friction properties. As the nano-diamond particles having a small size effect, the surface can be polished to enhance the surface hardness and, as it is spherical and semi-spherical ball bearing effect may be formed on the friction surface, exhibits excellent lubricating properties.

2. Nano polycrystalline diamond with high hardness, small size and high adsorption, its role in the application of technology in the important lubricating properties. Dry grinding friction is harmful, mainly in the energy losses and mechanical wear. Nano-diamond and non-diamond carbon nano-and small amounts of other additives in lubrication can form a stable colloidal dispersion system. As extreme pressure anti-wear agent solid colloidal particles of nano-diamond and non-diamond carbon in the lubricant evenly distributed through the oil as a carrier, when it appears to boundary lubrication conditions, it will play a peculiar effect.

3. Peaks with decreasing friction micro uneven surface, the contact area between the friction increases quickly and dramatically decreases rapidly by film extrusion, the film is not easily damaged, improve the sealing of the cylinder, spherical nano diamonds and quasi-spherical particles embedded in the contact friction between the dimples, excellent capacity, surface friction ball bearing effect, showing good lubricity
