Co–Ni–P and Co–W–P was studied by Georgiou et al. [218]. In 1990, Gonzalez et al. reviewed most of the ternary Ni–Me–P (Me = Cr, Mo, W, Fe, Cu, and Sn) alloy deposits [219]. They discussed the electrochemical and kinetic parameters, surface analysis and postplating operations as a link between Ni–P and Ni–Me–P autocatalytic alloys. Regarding electroless quaternary alloy deposits, only a few reports were published even in the 20 years where development was rapid. Hayashi [220] summarized knowledge of electroless quaternary alloy deposits to 1991.

This is somewhat accompanied by the development of nanoscience and technology, which has developed rapidly since the new millenium [274]. Nanoelectroless plating can be divided into three categories. The first is electroless nanocomposite plating, which is like electroless composite plating, but the codeposited composite particles are nanosized. For example, EN + Ni-cordierite and EN + diamond nanoparticles [275], EN + diamond and EN + CNT nanocomposite films [276], EN + A12O3 nanocoating [277, 278], History–From the Discovery of Electroless Plating to the Present Chapter | 1 39 electroless Ni–B + diamond nanocomposite coatings [279], EN + polymer nanocomposite coatings [280], EN + nano SiC coatings [281], EN + nanoSiO2 particles [282], electroless Ni–Zn–P + TiO2 nanocomposite coatings [283, 284], nanocomposite coating of EN + Ag [285], and nanocomposite coating of EN + Au [286].

They found that EN deposits (heating >200°C) produce structural changes that increase hardness, adhesion and abrasion, and wear resistance. The corrosion resistance, ductility, tensile strength, fatigue life, stress, and magnetic and electrical properties also are affected. The author’s group found that codeposition of tungsten in binary electroless Ni–P–W deposit improves the deposit’s wear resistance [139]. 0% elongation, respectively. In 1993, Yamada et al. [141] studied the strength evaluation and effect of graphite on strength of electroless nickel plating on cast iron.
