Studies on Electroless Coatings

Abstract: Since the introduction of Electroless (EL) coating in 1946 by Brenner and Riddle, the process has been the subject of steady growth. It is one of the most elegant methods available for the production of protective coatings on surface. The technique involves the autocatalytic reduction, at the substrate/solution interface, of cations released from suitable chemical reducing agents with in the EL bath. EL coating technique is simple one, as can be manifested just by controlling pH and temperature of the coating … Show more

“…The occurrence of a single semi-circle in the Nyquist plots indicates that the corrosion process of these coatings involves a single time constant. A similar conclusion of the existence of a single time constant has been reported by Agarwala and Younes et al [11].…”

“…The purpose of the duplex Ni-W-P layer on Ni-P coating can be explained by the fact that Ni-W-P has better properties in terms of corrosion and wear than Ni-P which in turns, has better adhesion/contact with the mild steel substrate, so that it acts as better intermediate layer [7][8][9]. The improved corrosion resistance of this coating is due largely to the huge amount of grain boundary diffusion paths provided by the nanostructure of the Ni 3 P and crystalline Ni at high temperature, caused by the furnace annealing especially if air cooled, which favored the formation of the dense nickel-tungsten and nickel oxide films on the surface [10][11][12][13]. Fig 1, shows a mini-prototype bath for electroless plating with compositions and operating conditions outlined in Table 1.…”

“…Nickel is one of the most used elements, and its applications cover almost all sizes and applications in science and technology. Some of its uses today and novel applications in the future would benefit greatly from nickel materials designed down to nano sizes, such as in catalysis, , electrodes, , chemically protective coatings, soft magnetic material, and low-temperature super plastic materials. , …”

“…There are many effective methods of coating nickel on carbon nanomaterials [9] . One of them is the electroless plating method [10,11] , which has been widely employed to coating Ni on various materials. Using this method, Ang et al [12] and Kong et al [13] have successfully obtained carbon nanotubes with coated nickel which is served as a heterogeneous catalyst and as a medium for adhesion and transferring loads.…”
