Disclosed are a method for coating metal, a metal member comprising the coating layer formed thereby, and a fuel cell separator. A method for coating metal according to an embodiment of the present invention includes preparing a metal base material; and forming a molten pool by irradiating a laser to a surface of the metal base material and forming a coating layer using an additive manufacturing by supplying a powder made of any one of Si, SiC, and a mixture of Cr and Al to the molten pool.

The present disclosure relates to a chromium-aluminum binary alloy with excellent corrosion resistance and a method of producing the same, and more particularly to a chromium-aluminum binary alloy with excellent corrosion resistance. The chromium-aluminum binary alloy may be easily produced and has ductility, thus being highly applicable as a coating material for a material requiring high-temperature corrosion resistance and wear resistance.

An oxide dispersion strengthening (ODS) method of a metallic material using a laser is provided, which includes melting a surface of a metallic matrix placed on a movable stage by irradiating a laser onto the surface (step 1), supplying an oxide dispersion strengthening (ODS) powder at a site of the matrix surface which is melt at step 1 (step 2), and cooling the matrix in which the ODS powder is supplied at step 2 (step 3). Because oxide particles are directly supplied into previously-made sheet or tube matrix, fabrication process is simplified, fabrication cost is reduced, and end product is fabricated efficiently.
