Abstract: According to embodiments of the present invention, there are provided a mold stack, a molding system incorporating same and a method of aligning the mold stack. For example, a mold stack is provided. The mold stack comprises a first molding cavity defining component, a second molding cavity defining component and a third molding cavity defining component, with the second molding cavity defining component being located, in use, in-between the first molding cavity defining component and the third molding cavity defining component. At least one of the first molding cavity defining component and the third molding cavity defining component is associated with a respective compensator, the respective compensator configured to allow the at least one of the first molding cavity defining component and the third molding cavity defining component to align itself relative to the second molding cavity defining component.

Abstract: A protective coating for protecting a component from corrosion and oxidation at a high temperature and from excessive thermal stress, has a heat insulation layer including a ceramic material and an adhesion-promoting layer including a rhenium containing metal alloy. The metal alloy belongs to the alloys covered by the general term MCrAlY, where M represents cobalt and/or nickel and Y represents yttrium and/or at least one equivalent metal from the group including scandium and the rare earth elements. The protective coating is distinguished by high oxidation resistance and corrosion resistance of the alloy, by outstanding thermal fatigue properties and an effective and permanent bond between the alloy and the ceramic heat insulation layer. As a result of the heat insulation, the temperature at the outer surface of the protective coating can be considerably higher than with purely metallic protective coatings, without an increased thermal load being exerted on the component.
