Electroless Ni‐P Based Nanocoating Technology—A Review

Abstract

An advancement of electroless, (EL) Ni‐P based coatings from micro to nano level is being discussed in this present review. This paper provides a coherent understanding of the EL coatings in terms of systems, bath composition for metal/alloy and composite coatings. The elements of the EL composite bath have been discussed. The studies on the second phase nanosized particles dispersed in the Ni‐P matrix have been illustrated. The bonding mechanisms of EL coatings with the substrates have been discussed. The morphology, physical and mechanical properties of the Ni‐P‐X (X the second phase particles added into EL Ni‐P matrix) composite coatings have discussed. A few applications have also been outlined that may reveal the capabilities of the EL Ni‐P based nanocomposite coating technology to the relevant industries with the emphasis on tribological, corrosion, and magnetic behavior.
