Electrodepositing nickel silica nano-composites coatings

The nano SiO2 ceramic particles were dispersed within the Ni-base solution by the high energy mechanical chemistry method (a patent method) to form the Ni/SiO2 solution and then the Ni/SiO2 co-electrodeposition coating was prepared. The co-electrodeposition coating possessed finer crystal grains. The SiO2 particles were dispersed evenly within the coating, and the bonding between the matrix metal Ni and the SiO2 ceramic particles is compact.
