PROBLEM TO BE SOLVED: To provide a method for manufacturing a complex metallic product with a film superior in quality and adhesiveness, and a composite metal which satisfies all required characteristics like a film forming speed, convenience of a process, a low environmental load and so on. SOLUTION: This manufacturing method comprises spouting a non-molten metal powder at a high speed onto the surface of a substrate, and forming a metallic coating by plastically deforming the metal powder, or a coating of metal compounds by reacting the above metal powder with an atmosphere gas, on the surface of the substrate. The provided metal coating or the metallic compound coating on the surface of the metal product has a porosity of 10% or less, and has a compressional residual stress. COPYRIGHT: (C)2004,JPO
