“…1,2 Nickel-phosphorous (Ni-P) is widely used as an electroless coating in different industries because of its high hardness, excellent corrosion and wear resistance and its uniform coating thickness. Co-depositing another metallic or non-metallic elements or abrasive/lubricate particles or combination of them in binary Ni-P matrix can further enhance these properties.…”

SiC and SiO2 nano-particles were co-deposited with electroless NiP coating onto API-5L-X65 steel substrates with 7g/L load of nano-particles in the bath at pH 4.6 ± 0.2 and temperature of 90 ± 2°C. The hardness and corrosion resistance of the composite coatings were measured using microhardness, polarization and electrochemical impedance spectroscopy techniques, respectively. Moreover, the structure of the composite coatings was investigated by means of X-ray diffraction (XRD) technique, while their morphologies and elemental compositions were analyzed using a scanning electron microscope (SEM) equipped with an energy dispersive spectrometer (EDS). Results showed that co-deposited nano-particles caused an increase in the hardness of the composite coatings. Corrosion tests showed that addition of nano-SiO2 particles improved corrosion resistance of electroless Ni-P coatings in salty atmosphere but addition of nano-SiC particles decreased, due to the agglomeration of SiC nano-particles together with an increase in the porosity of the composite coatings.

“…The presence of nanoparticles in Ni-P matrix also reduced their wear rate, as reported for CNT [112], nanoAl 2 O 3 [116], and nano-SiO 2 [113,114]. For electrodeposited coating, incorporation of hard SiC nanoparticles into metallic matrix led to having better corrosion resistance and excellent wear resistance [152,[189][190][191][192][193].…”

“…This method is usually applied for producing the nanocomposite coatings with Niken matrix and nanofillers are carbide, nitrite, boride, or PTFE [49,81,82,[111][112][113][114][115][116][117]. In order to improve the hardness, anticorrosion, and antiwear of coating, the thermal posttreatment at 500-700 ∘ C should be applied.…”

“…By embedding nanocrystalline TiC in DLC matrix, Voevodin et al [103,154] obtained the hardness of 32 GPa for this nanocomposite coating. Vepřek et al [155,156] In another direction, in case of Ni-P electroless coatings, incorporation of other nanoparticles, such as CNT [111,112], nano-SiO 2 [113,114], nano-SiC [175,176], nano-WC [115], and nano-Al 2 O 3 [116], increased their hardness. The hardness of all these nanocomposite coatings also increased after thermal posttreatment at 400 ∘ C during 1 h. Similar result was obtained for the thermal sprayed coatings [47].…”

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.

“…They found that after heat treatment at 400°C, the hardness, and resistance of the ENP composite were greatly increased relative to those of the ENP coating [66]. The addition of a small amount of SiC to an electroless Ni-P bath to form Ni-P-SiC composites increased the hardness of the conventional Ni-P coating two-fold (from 4.5 for pure Ni-P to 8.5 GPa for Ni-P/SiC composite coating).…”

The metallic coating of surfaces plays a vital role in the protection of most industrial applications. Coatings can be carried through various routes (e.g., mechanical and electrochemical plating techniques). Electroless nickel coatings present unparalleled properties and a unique combination of corrosion and wear resistance features. Recently, the use and development of electroless nickel-phosphorus (ENP) coatings has attracted broad attention from many industries (e.g., oil and gas) due to their superior corrosion and wear resistance properties. In the present review article, mechanisms of ENP and preparation methods are briefly outlined. The review sheds light on properties of electroless Ni-P coatings and of their nanocomposites with an emphasis on new products and on their future development.
