Ni-Al2O3 nanocomposite coating, which was fabricated by eletrodeposition technique with the aid of ultrasonic and agitation. The effect of ultrasonic and agitation on the characteristics of the deposits was investigated by scanning electron microscopy (SEM) and microhardness tester. The results shows that ultrasonic and agitation result in decreasing of Al2O3 nanoparticles aggregation and increasing of Al2O3 nanoparticles uniformly dispersed on the matrix of the composite coating. The ultrasonic and agitation improved the Ni crystallization in the Ni-Al2O3 nanocomposite electroforming coating. Compared to the process of without ultrasound, the nanocomposite is prepared with ultrasonic and agitation, which has a higher stiffiness by the same current density and electrolyte. The average microhardness of the deposit reaches to 461.9 HV with ultrasonic and agitation, which is double of the conventional electroforming coating.
