“…Therefore, the addition of Ti nanoparticles (TNPs) into to the NiP coatings is a possible way to improve its hardness, toughness, and corrosion resistance. Studies on mechanical, corrosion, and erosion characteristics of electroplated NiP coatings containing Ti particles exist more in the literature [ 15 , 23 , 24 , 25 , 26 ]. However, a few studies are available for electroless NiP-Ti composite coatings describing their mechanical, corrosion, and erosion behavior [ 27 ].…”

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.

“…When the ARB‐processed samples were heat treated, Al and Ag diffused into the copper matrix and new phases could form based on the Cu–Al–Ag phase diagram. [ 25 ] The type of new phases depends on two things: heat treatment temperature and time. The effect of these parameters on the diffusion length can be expressed as: [ 25 ]

x = 2 \sqrt{t}

where x is the diffusion length, D is the diffusion coefficient, and t is the diffusion time.…”

In this study, Cu/Al/Ag layered composites with two silver powder concentrations (2 and 3 wt.%) were fabricated with the aid of accumulative roll bonding (ARB). The ARB‐ed samples were heat treated at different temperatures (750, 850, 950 and 1050 °C), times (30, 45 and 60 minutes) and cycles (1‐9 cycles) to produce Cu‐Al‐Ag shape memory alloys (SMAs). The samples were characterized by X‐ray diffraction (XRD), scanning electron microscope (SEM) and electron backscattering diffraction (EBSD). Phase transformation temperatures were measured by differential scanning calorimetry (DSC). Strain recovery and shape memory behavior were evaluated by bending and tensile tests, respectively. The results indicated that alloys containing 2 wt.% Ag, rolled till 9 cycles, heat treated at 950 °C for 60 min, and samples with 3 wt.% Ag, fabricated by 9 cycles, annealed at 850 °C for 60 min showed maximum β martensite phases amount. Strain recovery ratio of the first and second samples were 71.7% and 71.2%, respectively. Additionally, the tensile test showed that the residual plastic strain and the recovered strain for the first sample with 2 wt.% Ag was equal to 0.7% and 3.0%, respectively. These results for the second sample with 3 wt.% Ag were 1.2% and 3.4%, respectively.This article is protected by copyright. All rights reserved.

Electrodeposition is a low-cost and low-temperature method for producing metal matrix composite coatings. The electrodeposition of Ni matrix/Ni-Cr-B particles is considered as the co-deposition of Ni-Cr-B particles in a Ni matrix, resulting in nanocomposite coatings that can ofer good wear and corrosion resistance between other applications. For comparison, the electrodeposition of Ni ilms and their wear and corrosion evaluation were also carried out under the same conditions. Some coatings usually contain oxide or carbide particles in micrometer size and are electrodeposited in a nickel matrix; however, the use of the mechanical alloying process ofers the possibility to reduce the particle size in the order of nanometers obtaining solid solutions, amorphous phases, or intermetallic compounds during the development of new alloys to be co-deposited, improving the engineering materials properties. This kind of nanocomposite can be used in industrial components with an irregular geometry exposed in aggressive environments such as the energy generation and oil industry.
