A coating and coating process for incorporating surface features on an air-cooled substrate surface of a component for the purpose of promoting heat transfer from the component. The coating process generally comprises depositing a first metallic coating material on the surface of the component using a first set of coating conditions to form a first environmental coating layer, and then depositing a second metallic coating material using a second set of coating conditions that differ from the first set, such that an outer environmental coating layer is formed having raised surface features that cause the surface of the outer environmental coating layer to be rougher than the surface of the first environmental coating layer.
A process of forming raised surface features on a surface of a component for promoting heat transfer from the surface, the process comprising the steps of:
A process of forming turbulators on a substrate surface of a gas turbine engine component, the process comprising the steps of:
