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%
