Abstract: This paper reviews the methods of formation of electroless Ni–P, multiple coatings, rare earth included coatings, nano-coatings and their effect on coating characteristics, applications and their recent developments. Evidence from the literature showed that the properties of electroless coatings could be improved by controlling different process.

Keywords: electroless coating, Ni–P, coating characteristics, nano-coatings.
