Ceramic coating

thermal insulationwear-resistantfor metal structures

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 °. Applications 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,
