“…The impedance of the NiP coating is further increased with the reinforcement of TNPs. As is well known, Ti itself is a corrosion-resistant metal [ 48 ], which leads to improving the corrosion-resistance of the NiP coatings. Furthermore, the NiP coatings may be more porous; therefore, it becomes denser with the addition of TNPs, and its porosity decreases, reducing the active sites for the corrosion and preventing the direct contact of electrolyte with the substrate [ 49 ].…”

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.

“…This means that the TiN coating can improve the wear resistance of the NiTi sample. Higher hardness and good adhesion of the applied coatings can be responsible for increased wear resistance [50][51][52]. The presence of a hard ceramic layer on the surface can prevent direct contact between the pin and substrate and protect the NiTi substrate from deformation and friction [53].…”

The preparation of a thin hard coating is the main challenge in the coating of NiTi articles. To achieve a thin coating of titanium nitride (TiN) on NiTi substrate, physical vapour deposition (PVD) was proposed in this study. Deposition of TiN coating was carried out at the nitrogen flows of 0.79 and 0.93 Pa. Phase composition, thickness, porosity, adhesion strength, hardness, and tribological properties of the TiN coatings were evaluated. The adhesion of the coating to the substrate was acceptable. Increasing of the gas flow resulted in a higher thickness (1 μm), lower porosity and higher adhesion strength. On contrary, the samples prepared with the lower gas flow showed higher hardness and elastic modulus. The coated samples showed smaller width of wear, lower wear rate and lower friction coefficient in comparison to the substrate. The delamination and adhesive wear mechanisms govern the wear process.
