Abstract
A method of forming a layer on a first component according to various aspects of the present disclosure includes melting a portion of a first metallic composition of the first component. The melting includes directing a laser beam toward a first surface of the first component. The method further includes depositing a second metallic composition on the first surface by directing a precursor including the second metallic composition toward an intersection of the first surface and the laser beam. The second metallic composition is galvanically more noble than the first metallic composition. The method further includes forming the layer on the first component by solidifying the first metallic composition and the second metallic composition. The first component is configured to be joined to a second component by engaging a plurality of micro-anchors defined on the layer with a polymer of the second component.
