“…This obviously indicates a great integration of Nb 2 O 5 within the rich nickel. Also, it can be notified that there are two characteristic phases showed within the interface, the first is nodular like solid flakes and the second phase is like homogeneous clusters at the background as also observed by Oluyori and co-workers when they deposited Zn-Nb 2 O 5 coatings by electrodeposition technique on mild steel [16]. Ni coating showed some of the agglomerations of particles be caused Ni coatings seem to be denser and compact in comparison with Nb 2 O 5 -Ni coatings due to faster deposition rate of DC sputtering as also observed by Jahanzeb Bhatti and co-workers when they Investigation of the mechanical properties of electrodeposited nickel and magnetron sputtered chromium nitride coatings deposited on mild steel substrate [17].…”

The Nb2O5-Ni coating was processed using DC sputtering on structural steel and study characterization of composite coating SEM/EDS inspection indicated clearly perfect incorporation of Nb2O5 within the nickel rich. Increasing in surface roughness and decreasing in average diameters of particles were obtained for coated surface compared with uncoated surface from AFM analysis, in addition, microhardness test and thickness test showed that increasing of the hardness value to 163 HV for Nb2O5 - Ni composite coating compared to 132 HV for uncoated samples, the hardness for Ni coating also increasing to155 HV and the thickness for Nb2O5-Ni composite coatings increased significantly compared to uncoated samples.

“…However, a sharp increase in the corrosion rate was observed for samples with silicon additions between 6 wt.% and 8 wt.% over the deformation ratio. This could be attributed to the aggressiveness of the corrosion medium (Oluyori et al, 2017).…”

Nickel aluminum bronze (NAB) alloy has become increasingly popular due to its superior strength, corrosion resistance, and thermal properties. This study provides an in-depth analysis of the effect of silicon and deformation percentages on the mechanical and corrosion characteristics of NAB alloy, for marine and architectural applications. The research was carried out by systematically varying the silicon percentage (0-10%) while the percentage of deformation ranges from 0-10% at ambient temperature (32 oC), and subsequent changes in its mechanical properties and corrosion resistance were observed. Mechanical properties such as ultimate tensile strength, ductility, and hardness were evaluated using standard testing methods. The results indicated a significant correlation between the silicon percentage and the mechanical properties. Specifically, an increase in the silicon percentage was found to enhance the tensile strength from 190.7 MPa to 590.8 MPa, the ductility from 23.7% to 46.9% and the hardness from 130.5 HV to 262.4 HV values of the NAB alloy. The corrosion rate of 5.49 mm/a was obtained for the reference material containing 0% Si at 0% (X0-0) deformation, while the least corrosion rate of 9.8x10-5 mm/y was recorded for 2 wt. % Si at 10% deformation (X2-5). These findings have significant implications for the use of NAB alloy in marine and architectural applications. When the silicon percentage is optimized, the mechanical strength and corrosion resistance of the alloy are enhanced, thereby improving the durability and longevity of structures made from the developed NAB alloy

“…The zinc interface displayed more nodular microstructure on the coating network with redefined morphologies. Oluyori et al [27] observed that the zinc metal functions as the load for the particles' dissemination or diffusion, and this culminates in the improvement of the nanocomposites' morphology and strong adhesion with the steel.…”

In most industries, Lightweighting has become a popular concept. Production of low-density components is presently seen as a technique for achieving improved handling and efficiency in manufacturing industries. Thus, low-density Si3N4 ceramic particles were introduced into the matrix of zinc to produce low-density Zn-Si3N4 nanocomposite films. After preliminary experimental runs, Zn-Si3N4 nanocomposite coated mild steel samples were produced at 0.3 and 0.5 V, and at an invariable temperature of 45 oC. The mass concentration of Si3N4 ceramic particles varied between 7 and 13 g L− 1. The corrosion rate (CR) of the coatings was examined through the potentiodynamic polarization method in 0.5 M of sulphuric acid solution, while the coatings’ microstructure was studied using XRD and SEM. The wear volume (WV) and coefficient of friction (COF) of coated samples and an uncoated sample were investigated using a pin-on-disc tribometer. The samples’ electrical conductivity was studied using simple ammeter-voltmeter equipment. The potentiodynamic polarization test results signified that the thin films reduced the CR of mild steel from 12.3450 mm year− 1 to 2.6793 mm year− 1, indicating noteworthy passivation of the films. The refined morphology of the coated surfaces as revealed by the SEM micrographs was ascribed to the dissolution and dispersion of nanoparticles. The XRD crystallographic phases of the coated samples also showed that the thin films possessed excellent texture, high stability and chemical homogeneity, and. More so, the coated mild steel samples exhibited lower COF relative to the uncoated sample. The thin film reduced the WV of the mild steel from 0.00508 mm3 to 0.00266 mm3, which indicated that strengthening mechanisms existed between the steel and the coating interface. The electrical conductivity test further shows that the Zn-Si3N4 film reduced the electrical conductivity of mild steel from12.97 Ω−1cm−1 to 0.64 Ω−1cm−1.
