Electroless Ni‐P Nano Coating Technology

This study ascribes advancement of electroless Ni‐P coatings of nano level by controlling the process by controlling bath composition for the coating of metal/alloy or nanocomposite. Effect of Ni‐P coating on different substrates with parameters like coating thickness, deposition rate, Ni‐P globule size, etc. have been extensively analyzed by using different characterizations techniques. Various second phase nanosized particles (ZrO₂‐Al₂O₃‐Al₃Zr, hexaferrites, ferrites, ZnO, Al₂O₃‐TiO₂, etc.) dispersed in the Ni‐P matrix have been illustrated. A few applications have also been outlined, which may reveal the capabilities of the EL Ni‐P based nanocomposite coatings for relevant industrial applications with emphasis on tribological, corrosion, magnetic properties, etc.
