    • PROBLEM TO BE SOLVED: To enhance the joining force between a metal alloy part and a coating in a metal-coat article to be used as an external facing material for various equipment in order to prevent floating and cracking of the coating film, improve the weatherability and prolong the lifetime of equipment. SOLUTION: A method of manufacturing a metal-coated article by selecting an acidic/basic aqueous solution fully corrosive to the metal of a mechanically processed metal alloy and carrying out necessary additional processes based on the process of immersing the metal alloy in the aqueous solution and washing with water in order to produce a metal alloy part which (a) has a rugged surface of a period of 0.5-10 μm, (b) has an ultra-fine rugged surface of a 10-300 nm period on the rugged surface of (a) and (c) keeps the whole surface covered with a ceramic thin layer. A metal-coat article is obtained by applying a coating to the surface-treated metal alloy part: especially, a coat layer adhered strongly to the metal phase is obtained by applying a one-part liquid type thermosetting coating to the metal alloy part.
