Nanodiamond suspensions are widely used in electroplating. Nanodiamond additives to galvanic electrolytes significantly improve mechanical properties of coated surfaces:
1. Increase in the wear resistance:

• Cr + nanodiamonds: 2-12 times
• Ni + nanodiamonds: 4-9 times
• Cu + nanodiamonds: 9-10 times
• Au + nanodiamonds: 1.8-5.5 times
• Ag + nanodiamonds: 4-12 times
• Sn + nanodiamonds: 3 times
• Al + nanodiamonds: 10-13 times

2. Increase in the microhardness:

• Cr + nanodiamonds: up to 1400-1500 kg/mm
• Ni + nanodiamonds: up to 800-900 kg/mmü C
• Cu + nanodiamonds: up to 160 kg/mm
• Ag + nanodiamonds: up to 180 kg/mm
• Au + nanodiamonds: up to 250 kg/mm
• Al + nanodiamonds: up to 600-700 kg/mm

3. Decrease in the porosity of a coating layer:

• Zn + nanodiamonds: 6-8 times lower
• Sn + nanodiamonds: 7 times lower
• Au + nanodiamonds: 6 times lower
• Ag + nanodiamonds: 8 times lower
• Cu + nanodiamonds: poreless coating

4. Improvement of corrosion resistance:

• Cu + nanodiamonds: no reduction of mass observed in standard tests
• Zn + nanodiamonds: resistance increased 2-4 times

Nanodiamonds in electrolytes increase in the product durability by the factor of 2-15 times.

Numerous applications include:

• – Punches, dies, matrices and molds
• – Screws, check valves and sprues
• – Gears, shafts and pistons
• – Metal cutting toolsü Bearings
• – Food processing equipment
• – Petrochemical processing equipment
• – Gun barrels

Ray Techniques’ advantage: stable nanodiamond slurriess for galvanic, anodizing and electroless coatings.
