摘要:
Disclosed is a method for producing a coating system on a component, wherein at least one coating is deposited on the component by way of atmospheric plasma spraying (APS) and at least one further coating is deposited by way of suspension plasma spraying (SPS). The coatings are particularly advantageously deposited in the sequence of APS+SPS or APS+SPS+APS or APS+SPS+erosion coating. These sequences of coatings applied in this way usually have an effect providing a first porous coating and a second porous coating disposed thereon, wherein the porosity of the second coating is greater than that of the first coating, and wherein the reflectivity is greater than that of the first coating. The increased reflectivity of the coating, particularly in the visible (VIS) and the near infrared (NIR) wavelength ranges, advantageously causes a lower thermal load for the substrate material because a smaller proportion of thermal radiation penetrates the ceramic thermal barrier coating, resulting in lower heating of the substrate (component).
