Extra-hard coatings based on ceramic and carbide materials




Production

These coatings can be applied to metals, glass and fibre reinforced plastics (CRP, GRP). They provide protection against abrasive and erosive wear as well as cavitation and corrosion. What is more, the ceramic coatings feature outstanding thermal and electrical insulation properties.

Advantages of a ceramic coating

Materials

  • Oxide ceramics: aluminium oxide, titanium dioxide, chromium oxide, zirconia oxide as pure oxides as well as two- and three-component blends of these
  • Aluminium, copper, bronze, molybdenum, as well as various alloys

Technical features

  • Layer thicknesses ranging from 0.1 to 2.0 mm
  • Hardness of 600-1500 HV, particle hardness of approx. 2500 HV
  • Electrical insulation
  • Thermal insulation
  • Anti-adhesion properties
  • Shock resistant
  • Application temperature range: -150°C to +900°C
  • Max. dimensions: length = 6000 mm, Ø = 1000 mm, weight = 2,5 tons
  • Larger dimensions and weights upon request

Examples of application

  • Coatings with finished surfaces (ground or polished) are suitable for sealing and sliding surfaces of rotating and oscillating machine parts, e.g., shafts, rollers, wearing rings, sleeves, plungers, pistons, piston rods as well as any other seals including gaskets, collars, shaft seals and O-rings. Counter rotation components are typically made from bronze, carbon, stainless steel, carbide and sintered metals
  • Due to their higher layer thickness, sprayed or smoothed coatings are particularly suitable to prevent friction wear, e.g., for rollers, impeller type mixers, agitators and screw conveyors
