In this work, Ni coatings were fabricated by mechanical coating technique (MCT). The coatings were characterized by X-ray diffraction (XRD), and scanning electron microscopy (SEM), among others. The formation process of Ni coatings was examined. The results revealed that the formation of the coatings consist of the adhesion of Ni to ceramic balls and the cold-welding between Ni particles. Besides, the effect of some influencing factors on the formation of the coatings was also investigated. The results proved that higher rotation speed was favor of the coating formation. The substrate material and its surface condition also had great influence on the coating formation.
