Coating CERTECH

SURFACE RESTORATION (THERMAL COATING “CERTECH” Sp. z o. o.)

– MODERN COATINGS FOR INDUSTRY;

– INNOVATIVE TECHNICAL SOLUTIONS;

Thermal spray coating technologies provide tremendous opportunities for the repair and recovery of machine parts.

These technologies allow:

  • Change the properties of the top layer of a device part, for example, strength, roughness, coefficient of friction
  • Recover nominal dimensions – the possibility of regeneration and repair of parts
  • Increase the reliability of parts and devices
  • Increase the technical availability of production workshops and equipment
  • Extend overhaul periods
  • Protect new machine parts from accelerated (premature) wear

Our offer includes the application of ceramic coatings, also carbide and metal, with the following characteristics:

  • High hardness of the coating layer up to 70 HRC and microhardness up to 1600 HV0.3
  • Resistant to abrasion, erosion and cavitation
  • Corrosion resistant
  • Low coefficient of friction of the coating on sliding surfaces
  • Resistant to high temperatures, oxidation, hot gases
  • Thermal barriers
  • High electrical resistance – ceramic dielectric layers
  • Excellent thermal and electrical conductivity (e.g. copper coatings)
  • Thickness from 50 µm to 10 mm
  • High level of adhesion of the coating to the base – up to 100 MPa
  • Tightness and low porosity of coatings from 0.1%
