Abstract:
A protective coating for a metallic component in direct contact with the condensate of a liquid medium, comprising at least two layers of amorphous material on top of one another, the outermost one of the two layers of amorphous material being a hydrophobic layer and the innermost one of the two layers of amorphous material being an erosion-resistant layer, wherein the innermost layer has a high interfacial energy, highly elastic deformation properties and a hardness of between 1,500 HV and 3,000 HV, the outermost layer has an interfacial energy and deformation properties lower than those of an erosion-resistant layer, and each hydrophobic layer has a hardness of between 500 HV and less than 1500 HV.
