摘要:
A coated metal component includes an aluminum alloy substrate and a protective aluminum coating on a substrate. An interfacial boundary layer between the coating and substrate enhances coating adhesion. The boundary layer includes isolated regions of copper or tin produced by a double zincating process. The protective aluminum coating exhibits improved adhesion and is formed by electrodeposition in an ionic liquid.

The invention relates to reactive metallic systems and to methods of producing reactive metallic systems. Such systems consist of metallic particles in the form of powders or pastes, or of metallic multilayer structures. To prevent the reaction product of the described self-propagating reactions from being a brittle material, it is suggested in the invention that the reactive metallic system be designed as a multilayer structure made up of thin layers of ruthenium and aluminium deposited sequentially one upon the other, or as a powder consisting of ruthenium and aluminium particles. The object is established according to the invention by selecting Ru/Al as the basic system. The strongest exothermic reaction and thus the greatest amount of liberated heat are to be expected from stoichiometrically constructed reactive systems. The heat of formation is highest here. The intermetallic phase formed is advantageously RuAl, which, unlike many comparable intermetallic phases, such as NiAl, is extremely ductile at room temperature.
