Summary

The technology of vacuum-plasma nanostructural hardsurfacing coatings on the basis of diamond-like carbon, high-melting metals (titanium, chromium, molybdenum), their chemical compounds (nitrides, carbides, carbonitrides, oxicarbonides) is destined for increase of endurance of metal, alloy, wood and plastic working tools as well as working tools made from artificial resin.

Description

The method consists in the use of vacuum-arc method of high-speed flows of carbon plasma and high-melting metal plasma that are generated by impulse and stationary plasma accelerators. The technology is used for industrial application, and has the following engineering-and-economical performance indicators:

• average consumed power — max. 25 kW
• duration of the technical process — max. 2 hours;
• number of controlled process parameters — 6;
• tool temperature for coating sedimentation process — 200 °C;
• cost increase of tool with coating — max. 30% of tool cost without coating.

• number of layers – 2-5;
• thickness of each layer — 0,1-1,0 μm;
• coating thickness — 0,3-3,0 μm;
• hardness — 25-85 GPa;
• thermal fastness – min 300 °C.

Technology type

• Other:
  Resource-saving, environmentally safe.

Technical advantages and economic benefits

Endurance of a working tool increased by 1.5–3 times. The increase in endurance of profiled blades for steel processing makes over 10 times. The resource-saving technology is the economy of instrument steel. Eco-friendly industry.
