An arrangement of components (12, 13, 30) for a wind power plant. A first component (12, 13) has a flange (15, 130) having a flange contact surface (121, 122, 133). A second component (30) has a flange-mounting surface (131, 132) for a flange (15, 130) of the first component (12, 13). Alternatively, the second component (12, 13) has a flange (15, 130) having a flange contact surface (122, 133) and the flange contact surface (122, 133) of the first component (12, 13) and the flange-mounting surface (131, 132) of the second component (30) are arranged opposite each other, or the flange contact surfaces (122, 121) of the components are arranged opposite each other. At least one flange contact surface (121, 122, 133) of a flange (15, 130) and/or the flange-mounting surface (131, 132) of the second component (30) has an outer coating made of a chrome-steel alloy.
