Topocrom® can be used up to a temperature of 400 ° C, The hardness of the Topocrom® coating will be reduced at higher temperatures
All electrically conductive metals can be coated. Roughness value of the functional surface before coating Rz <4 µm The surface should be free of defects such as pores, grooves, grinding commas etc. Chrome layers do not eliminate surface defects in the base material.
The layer thickness depends on the desired structure and roughness of the Topocrom® layer. Example: Rz 4-6µm, layer thickness 18-20µm. With higher roughness values, the layer thickness increases accordingly. As a rule, however, layer thicknesses up to 120µm are possible.
