Advantages of Nano Diamond
Increase in quality and competitiveness, i.e.
- Increase wear-resistance & high microhardness
- Increase in corrosion resistance
- Heightened abrasion resistance
- High fill-ability and low porosity.
- Heightened adhesion.
- Lowered friction coefficient.
- High electro- and thermal-insulation properties.
Increase in service life of products.
Saving in materials, energy-and labor costs.
