Corrosion and heat treatment studies are essential to predict the performance and sustainability of the coatings in harsh environments, such as the oil and gas industries. In this study, nickel phosphorus (NiP)–titanium (Ti) nanocomposite coatings (NiP-Ti nanoparticles (TNPs)), containing various concentrations of Ti nanoparticles (TNPs) were deposited on high strength low alloy (HSLA) steel through electroless deposition processing. The concentrations of 0.25, 0.50 and 1.0 g/L TNPs were dispersed in the electroless bath, to obtain NiP-TNPs nanocomposite coatings comprising different Ti contents. Further, the effect of TNPs on the structural, mechanical, corrosion, and heat treatment performance of NiP coatings was thoroughly studied to illustrate the role of TNPs into the NiP matrix. Field emission scanning electron microscope (FESEM) and energy dispersive spectroscopy (EDX) results confirm the successful incorporation of TNPs into the NiP matrix. A substantial improvement in the mechanical response of the NiP matrix was noticed with an increasing amount of TNPs, which reached to its ultimate values (hardness 675 Hv, modulus of elasticity 18.26 GPa, and stiffness 9.02 kN/m) at NiP-0.5TNPs coatings composition. Likewise, the electrochemical impedance spectroscopy measurements confirmed a tremendous increase in the corrosion inhibition efficiency of the NiP coatings with an increasing amount of TNPs, reaching ~96.4% at a composition of NiP-0.5TNPs. In addition, the NiP-TNPs nanocomposite coatings also unveiled better performance after heat treatment than NiP coatings, due to the presence of TNPs into the NiP matrix and the formation of more stable (heat resistant) phases, such as Ni3P, Ni3Ti, NiO, etc., during the subsequent processing.

“…The coating roughness significantly affects the tribological performance and corrosion resistance of the coatings under service [ 64 , 65 ]. From the tribological point of view, friction depends on the deposited coating’s surface roughness, and a smoother surface gives a lower friction coefficient (COF) [ 66 ]. In HiPIMS, surface properties of the deposited coatings are tailored by changing the average power.…”

The high-power impulse magnetron sputtering (HiPIMS) technique is widely used owing to the high degree of ionization and the ability to synthesize high-quality coatings with a dense structure and smooth morphology. However, limited efforts have been made in the deposition of MAX phase coatings through HiPIMS compared with direct current magnetron sputtering (DCMS), and tailoring of the coatings’ properties by process parameters such as pulse width and frequency is lacking. In this study, the Cr2AlC MAX phase coatings are deposited through HiPIMS on network structured TiBw/Ti6Al4V composite. A comparative study was made to investigate the effect of average power by varying frequency (1.2–1.6 kHz) and pulse width (20–60 μμs) on the deposition rate, microstructure, crystal orientation, and current waveforms of Cr2AlC MAX phase coatings. X-ray diffraction (XRD), scanning electron microscopy (SEM), and atomic force microscopy (AFM) were used to characterize the deposited coatings. The influence of pulse width was more profound than the frequency in increasing the average power of HiPIMS. The XRD results showed that ex situ annealing converted amorphous Cr-Al-C coatings into polycrystalline Cr2AlC MAX phase. It was noticed that the deposition rate, gas temperature, and roughness of Cr2AlC coatings depend on the average power, and the deposition rate increased from 16.5 to 56.3 nm/min. Moreover, the Cr2AlC MAX phase coatings produced by HiPIMS exhibits the improved hardness and modulus of 19.7 GPa and 286 GPa, with excellent fracture toughness and wear resistance because of dense and column-free morphology as the main characteristic.

“…From overall samples, the lowest average surface roughness height (Sa) value was for the (0.4 wt.% ZnO+0.2 wt.% graphene) nano‐oil, which indicates superior hydrodynamic properties and consequently lower friction [27]. Based on ISO 25178, the texture roughness parameters were calculated according to whole analysis statistics from in‐depth surface finish device examined scar regions [41]. The average surface roughness height (Sa) contributes a great comprehensive summary of the height fluctuations were the highest (4.7822 μm) for the base oil and the smallest (2.8802 μm) for (0.4 wt.% ZnO+0.2 wt.% graphene) nano‐oil, Figure 16.…”

This research article investigates carefully the effect of different nanoparticles zinc oxide (ZnO), graphene, and combinations thereof in API base oil group ΙΙ (PBOÀ GΙΙ). The morphology of zinc oxide and graphene nanomaterials are depicted by transmission electron microscopy. Sonication treatment and dispersion stability investigations are carried out after the preparation of nanoparticles with surfactant (oleic acid) and pure base oil group ΙΙ for certain concentrations. Oil formulations tested by using a four-ball machine to find out the coefficient of friction (COF), wear scar diameter (WSD), and specific wear rate (SWR) for each sample. Additionally, scarred balls are characterized by using field emission scanning electron microscopes (FE-SEM), energy-dispersive x-ray spectroscopy (EDX/EDS), elements mapping, Raman spectroscopy, and a three-dimensional surface texture analyzer to study the morphology of sliding balls after the tribological experiments and to confirm the presence of (zinc oxide + graphene) on the machined balls. Surface roughness measurements implemented for identifying surface finish of scarred balls. The experimental results and surface analyses showed that (0.4 wt. % ZnO + 0.2 wt.% graphene) nanolubricant has outperformed behavior compared to base oil group ΙΙ due to the formation of tribofilm on the contacting surfaces during sliding motion.
