“…Reinforcing the Ni-P matrix with hard ceramics to improve its mechanical performance and enhancing its corrosion resistance ability are a comparatively novel idea that becomes tempting when the reinforcements are at the nanoscale. This reinforcing of hard ceramic nanoparticles improves the mechanical strength of the Ni-P coating. , Enhancement in the characteristics of the Ni-P matrix has been obtained by considering numerous reinforcements as reported in the literature such as SiC, TiO 2 , C 3 N 4 , and WC, ZrO 2 , TiC, etc.…”

Superior corrosion resistance along with higher mechanical performance is becoming a primary requirement to decrease operational costs in the industries. Nickel-based phosphorus coatings have been reported to show better corrosion resistance properties but suffer from a lack of mechanical strength. Zirconium carbide nanoparticles (ZCNPs) are known for promising hardness and unreactive behavior among variously reported reinforcements. The present study focuses on the synthesis and characterization of novel Ni-P-ZrC nanocomposite coatings developed through the electrodeposition technique. Successful coelectrodeposition of ZCNPs without any observable defects was carried out utilizing a modified Watts bath and optimized conditions. For a clear comparison, structural, surface, mechanical, and electrochemical behaviors of Ni-P and Ni-P-ZrC nanocomposite coatings containing 0.75 g/L ZCNPs were thoroughly investigated. The addition of ZCNPs has a considerable impact on the properties of Ni-P coatings. Enhancement in the mechanical properties (microhardness, nanoindentation, wear, and erosion) is observed due to reinforcement of ZCNPs in the Ni-P matrix, which can be attributed to mainly the dispersion hardening effect. Furthermore, corrosion protection efficiency (PE%) of the Ni-P matrix was enhanced by the incorporation of ZCNPs from 71 to 85.4%. The Ni-P-ZrC nanocomposite coatings provide an exciting option for their utilization in the automotive, electronics, aerospace, oil, and gas industry.

“…The hardness of the nanocomposite coating in the presence of TiO 2 nanoparticles is much higher than that of the coating with Ni‐P. [ 83 ] The hardness is increased from 520 HV up to 650 HV especially from 805 to 1050 after heating at 400°C for 1 hour. The corrosion resistance of the nanocomposite coating is far superior to that of the Ni‐P coating, thanks to the incorporation of TiO 2 particles while the copper deposition has accelerated the passivation of the nickel thereby improving the corrosion resistance of composite coatings.…”

Coating is widely known as an effective conventional method in anti‐corrosion. In combination with nanomaterials, the coating has been controlled at nanoscale, which is coined as nanocoating and exhibits superior protection functionality. In this review, we extensively discuss different coating approaches that have utilized advanced materials such as nonconductive and/or conductive polymers, nanoparticles, and their nanocomposites. Finally, some suggestions and future perspectives regarding utilization of nanocoating in anti‐corrosion are also put forward.

“…For example, Ni-P coating hardness and wear resistance can be improved with the addition of nanoparticles. In recent years, the wear resistance of Ni-P has been studied with the addition of various ceramic carbide or oxide particles [1,[10][11][12][13][14][15]. However, a major disadvantage of Ni-P coating is its brittleness, and the hard particle additions do little to improve Ni-P's toughness [2,3].…”

Protective coatings can prolong the lifespan of engineering components. Electroless Ni-P coating is a very hard coating with high corrosion resistance, but low toughness. The addition of NiTi nanoparticles into the coating has shown the potential to increase the toughness of electroless Ni-P and could expand its usability as a protective coating for more applications. However, the study of the tribological behaviour and wear mechanisms of Ni-P-NiTi composite coating has been minimal. Furthermore, there is no studies on the effect of coating thickness on monolithic and composite electroless Ni-P coating wear behaviour. The wear rates of each coating were found by measuring the volume loss form multi-pass wear tests. The wear tracks were examine using a confocal microscope to observe the wear mechanisms. Each sample was tested using a spherical indenter and sharp indenter. It was found that the NiTi nanoparticle addition displayed toughening mechanisms and did improve the coating’s wear resistance. The 9 μm thick Ni-P-NiTi coating had less cracking and more uniform wear than the 9 μm thick Ni-P coating. For both the monolithic and composite coatings, their thicker version had higher wear resistance than their thinner counterpart. This was explained by the often observed trend in coatings where it has higher tensile stress near the substrate interface, which decreases and becomes compressive as thickness increases. Overall, the 9 μm thick Ni-P-NiTi coating had the highest wear resistance out of all the coatings tested.
