“…When polarized, after the 72 h immersion in 3.5% NaCl solution, no significant change occurred in the composition of Ni(OH) 2 in the entire corrosion product layer, compared with the values before polarization. An Al 2p 3/2 peak at 75.7 eV was, therefore, attributed to the formation of Al(OH) 3 . Its composition was greatly increased, especially on the outer surface of the corrosion product layer.…”

“…The characterization of the electrochemical corrosion behaviour of pure Ni coatings has been undertaken in neutral, alkaline and acidic corrosion environments using potentiodynamic polarization and X-ray photoelectron spectroscopy [1]. Co-electrodeposition of Ni coatings with micron or sub-micron size particles would yield Ni matrix composite coatings with better mechanical [2][3][4] and electrochemical properties [5][6][7] than pure Ni coatings. A high content of the reinforcement particles is usually important for improving the Ni coating properties.…”

The electrochemical corrosion behaviour of an electrodeposited Ni-28wt.%Al composite coating was characterized after 24 h and 72 h immersion periods in 3.5% NaCl solution, using electrochemical and surface probe techniques. Open circuit potential (OCP) and potentiodynamic polarization revealed that the Al particles modify the electrochemical corrosion behaviour of the Ni coating by shifting its E OCP more negatively and increasing its anodic dissolution current density, after 24 h immersion in 3.5% NaCl solution. Compared with the Ni coating, the composite can exhibit wellreduced anodic current density and slightly increased cathodic current with immersion up to 72 h. XPS characterization showed that a high rate of water adsorption and rapid formation of a continuous Ni(OH) 2 initially occurs on the composite surface which, however, readily thickens during prolonged immersion time and promotes the corrosion product enrichment with Al 2 O 3 . This greatly decreased the rate of corrosion and susceptibility to pitting for the Ni-28wt.%Al composite after 72 h immersion in 3.5% NaCl solution.

“…This method could be used for the fabrication of nanocomposite coatings, which contain organic nanofillers (such as PEO, PTFE [80,83,118]) or inorganic matrices [119][120][121][122][123] or organic matrices [19,22,32,78,124]. In the case of organic matrices, the electrochemical codeposition of nanocomposites has been reported by many researchers [123][124][125][126][127][128][129][130][131][132][133][134][135][136][137][138][139][140][141].…”

Incorporation of nanofillers into the organic coatings might enhance their barrier performance, by decreasing the porosity and zigzagging the diffusion path for deleterious species. Thus, the coatings containing nanofillers are expected to have significant barrier properties for corrosion protection and reduce the trend for the coating to blister or delaminate. On the other hand, high hardness could be obtained for metallic coatings by producing the hard nanocrystalline phases within a metallic matrix. This article presents a review on recent development of nanocomposite coatings, providing an overview of nanocomposite coatings in various aspects dealing with the classification, preparative method, the nanocomposite coating properties, and characterization methods. It covers potential applications in areas such as the anticorrosion, antiwear, superhydrophobic area, self-cleaning, antifouling/antibacterial area, and electronics. Finally, conclusion and future trends will be also reported.

“…The resulting composite possesses properties that differ from the bulk, depends on the degree and type of particle incorporation [4][5]. The properties of nano composite materials depend not only on the properties of their individual parents, but also on their morphology and interfacial characteristics [6][7]. Experimental work it has generally shown that virtually all types and classes of nanocomposite materials lead to new and improved properties, when compared to their macrocomposite counterparts.…”
