Anti-icing stacks for protecting an aerodynamic surface are described. In some embodiments, an anti-icing stack includes an anti-icing layer, an elastomeric erosion protection layer, and an additional layer. The erosion protection layer is disposed between the anti-icing layer and the additional layer. The additional layer has a thickness greater than the thickness of the erosion protection layer and a tensile modulus of no more than the tensile modulus of the erosion protection layer. The additional layer may be a foam adhesive layer.

The present invention relates to a rotor blade which has a coating, to a corresponding method for producing the coating, and to a method for heating and/or deicing the outer surface of the rotor blade and/or an outermost layer applied onto the outer surface of the rotor blade. The task underlying the invention is to develop a functional multi-layered coating that constitutes a comprehensive protection against the various environmental influences. The task is accomplished by a rotor blade which has an outer surface and by an at least two-layered coating applied onto the outer surface, having a first adhesion-facilitating metal layer and/or a first adhesion-facilitating layer which has electric heating elements and a second metal layer, wherein the first adhesion-facilitating metal layer and/or the first adhesion-facilitating layer which has electric heating elements is arranged between the outer surface of the rotor blade and the second metal layer.

A roller bearing includes: inner and outer rings; rollers interposed between raceway surfaces of the inner and outer rings and having a roller outer circumferential surface; a cage retaining the rollers; and a DLC film on the roller outer circumferential surface.

A method includes applying an infiltration coating on a thermal barrier coating of an article. The infiltration coating infiltrates at least some pores of the thermal barrier coating. The infiltration coating decomposes within the at least some pores of the thermal barrier coating to coat a portion of the at least some pores of the thermal barrier coating. The infiltration coating reduces a porosity of the thermal barrier coating. The method also includes applying a reactive phase spray formulation coating on the thermal barrier coating. The reactive phase spray formulation coating reacts with dust deposits on the thermal barrier coating.

A method of coating an area of a wind turbine rotor blade comprises: defining an area to be coated on a surface of the blade, applying a first plurality of strips of masking tape to the surface of the blade proximate a first edge region of the defined area such that each strip is arranged adjacent to at least one other strip of said first plurality of strips, spraying a coating layer onto the defined area up to an innermost strip such that the innermost strip defines an edge of the coating layer, removing the innermost strip(s) to expose an uncoated region of the defined area between the edge of the coating layer and an innermost remaining strip and spraying a further coating layer over the previous coating layer and over the uncoated region up to said innermost remaining strip.
