PROBLEM TO BE SOLVED: To provide an improved braze material for enhancement (e.g., coating, repair, or buildup) of a substrate or for joining of a plurality of substrates, and also to provide a brazing method using the braze material.SOLUTION: A method of brazing is provided which comprises: melting a surface region of a substrate; contacting a braze material with the melted surface region, the braze material including a plurality of braze fillers and a plurality of carbon structures; subjecting the braze material to an amount of energy effective to melt the braze fillers but not the carbon structures; and cooling the braze material to form a brazement including the carbon structures within at least a portion of the substrate. The brazement includes a gradient of the carbon structures, a concentration of the carbon structures increasing in a direction away from an interior of the substrate. |
