Ceramic coatings

The ceramic coating – a multi-talent

Ceramic coatings on steel or aluminium construction parts show excellent properties. They are resistant to wear, low-friction and have an electrical and thermal insulation effect. The ceramic layers are applied through thermal spraying with a standard thickness of 120 μm.

With longer machine runtimes, they contribute to lowering costs and safeguard the quality of your products through long-term stable surfaces.

As a competent partner for ceramic coatings, Rauschert in addition is also a competitive supplier of construction parts from technical ceramics and plastics.


Manufacturing procedures

The ceramic coatings are applied with a thermal spraying procedure (APS and HVOF) to the pre-processed metal surface and post-processed, depending on the application case. Thick-walled metal parts heat up to approx. 200 °C, so that no structural changes occur. One advantage is the free selection of the basic metallic material.

If high-quality machine components have failed due to wear, they can be repaired economically by applying a repair coating.
For this purpose, the damaged areas are being brought back to size with metallic layers by deploying arc spraying (AS). Afterwards, they can be coated with wear-resistant ceramic.

Coating on the inside is only possible if the area to be coated is accessible by the spray jet and the angle of incidence is > 45 °.



Ceramic coatings outperform hard-chrome layers in terms of hardness and wear resistance and have proven highly successful in numerous applications: Among other things, in textile engineering and wiring machine engineering, in appliances for soldering and welding, in electrical insulation layers on heating conductors up to approx. 500 V and 600 °C and for thermal insulation layers in the glass-processing industry.

In humid, corrosive surroundings, corrosion-resistant substrate materials such as stainless steel 1.4301 and aluminium are recommended due to the process-dependent porosity. In addition, the pores are impregnated with organic and inorganic sealants.

Antibacterial, so-called “bactericidal” coatings, applied on various surfaces, enable new prospects in the combat of bacteria and fungi. Bactericidal coatings on door handles have the potential to reduce the risk of contagion considerably.
