Abstract: Methods of applying a corrosion protection layer and components protected thereby are disclosed. In one embodiment, a corrosion-resistant assembly is provided including a first metal component joined to a second metal component, a joint interface between the first and second components, and a corrosion protection layer covering at least a portion of the joint interface, the corrosion protection layer including aluminum or zinc. The corrosion protection layer (CPL) may be applied by a spraying process, such as thermal spraying. The CPL may be a non-structural coating and may be formed of commercially pure aluminum (e.g., at least 99 wt. %). The CPL may form a seal between two components at the joint interface, for example, when components are joined using a hem-lock. The CPL may also be applied to newly machined surfaces, such as cut surfaces and punch surfaces to prevent or reduce corrosion.
