摘要：
A possibility to increase materials' performance for different applications is to protect them by coatings. Electroless nickel deposition represents an alternative method to obtain coatings on various substrates. Advancement in electroless Ni-P deposition is the codeposition of solid particles within coatings. By this method, composite layers with very good characteristics for specific applications can be produced. Ni-9% P/nano-Al2O3 composite coatings were deposited by electroless plating method, while their morphology and properties were examined via scanning electron microscopy, energy dispersive X-ray spectroscopy and microhardness tests. Electrochemical impedance spectroscopy and polarisation method was used to analyse the corrosion resistance of the coatings. The results showed that the addition of nano-Al2O3 particles improved the corrosion resistance and mechanical properties of electroless Ni-P coatings.
