- 2-10 times Increase in service life of the tool and details.
- Saving in materials, energy-and labor costs.
- 20-50% increase in capacity of galvanic lines at the expense of increase in speed of precipitation and reduction in thickness of a coating.
- Improvement of the ecological characteristics.
- Saving in noble metals at the expense of more thin layer of a coating at conservation of the same properties, energy and labor costs.
- Non toxic
- Increase in wear-resistance and microhardness
- Increase in corrosion resistance
- Decrease in porosity
- Increase in adhesion & cohesion and low friction factor
- Increase of throwing power of electrolyte of all metal
- Unporositive, uncracked coatings at lowered thickness.
- Content of Nano diamond in a metal coating is equal to average 0,3-0,5 wt. %.
Specific consumption of Nano diamond at metallic layer thickness of 1um makes up 0,2 g (1 carat) per 1 ㎡

Advantages of anode-oxide coating of aluminum and its alloy
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.
