A new coating process is offered to produce a coating layer on Fe plate by the mechanical milling process. In this paper, the Cu and Ni were applied over a steel substrate in the room temperatureand under the environment atmosphere using the crushing balls in different milling times for samples (Ni-30% Cu) in order to make coat. Bilateral entrance of nickel and copper elements during milling causes Ni-Cu solid solution to be made and the composite coat to be created over the samples surface. The microstructure properties of coat surface by use of varied analyses such as: field emission scanning electron microscope (FESEM), energy dispersive X-ray spectroscopy, surface roughness and friction analyses showed that the coat layer thickness reach to 100 micrometres. X-ray diffraction results proved the solid solution formation of nanocrystals
