“…26,27 The annealing temperature increases above 400°C, the intensities of Ni and Ni 3 P reflections were considerably increased and had become narrow. Meanwhile, Due to the lower concentration of TiO 2 nanoparticles, lesser number of peaks were observed in the X-ray pattern 6 as shown in Figure 5. The incorporated TiO 2 particle in the Ni matrix could affected the phase uniformity of the deposits surface.…”

“…3,4 The size, shape, nature, compatibility, and deposition rate of the particles in the co-deposition determine the useable properties of electroless Ni-P composite layer. 5 Various materials such as TiO 2 , SnO 2 , SiO 2 , ZnO, ZrO 2 , Al 2 O 3 , TiC, SiC, BN, WC, TiN, WO 3 , 6 MMT, 7 MOF 8 were co-deposited into the electroless nickel coatings to enhances various surface properties. The co-depositing transition metal oxide like TiO 2 particle into the Ni matrix enhances the electro catalytic activity by using hydrogen evaluation reaction in chlor-alkaline industries.…”

The Co-deposition of TiO2 particles (anatase type) of 200–300 nm with Ni-P electroless coatings on low carbon steel. The coated specimen was annealed by microwave and common electric furnace. The effects of microwave and furnace annealing temperatures on these coatings were characterized via. XRD, SEM, EDAX, and the corrosion performance was characterized through electrochemical polarization technique. The corrosion medium used for this work was sodium chloride (NaCl) solution and which contains 3.5 wt-% in distilled water. The result showed that, the microwave annealing method was enhanced the corrosion performance of the coating by diffused TiO2 particle into the matrix and reduced the micro voids presented in the matrix. Further, the corrosion mechanisms of the non-treated and the annealed coated materials have been explained in the consideration of crystallization, transformation of phases, grain size, and micro strain.

“…As shown in Figure 6a, the Nyquist plots of the alloys consisted of a bigger semicircular loop at high frequencies, which we attributed to capacitance characteristics, and a semicircular loop at lower frequencies caused by the inductance of the alloys. Normally, the diameter of the capacitor plays an important role in evaluating the anticorrosion properties of alloys [42]. In the case of these specimens, the larger diameter, the better corrosion resistance of the alloy.…”

The effect of Sn addition on the microstructure and corrosion behavior of extruded Mg–5Zn–4Al–xSn (0, 0.5, 1, 2, and 3 wt %) alloys was investigated by optical microscopy (OM), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), electrochemical measurements, and immersion tests. Microstructural results showed that the average grain size decreased to some degree and the amount of precipitates increased with the increasing amount of Sn. The extruded Mg–5Zn–4Al–xSn alloy mainly consisted of α-Mg, Mg32(Al,Zn)49, and Mg2Sn phases as the content of Sn was above 1 wt %. Electrochemical measurements indicated that the extruded Mg–5Zn–4Al–1Sn (ZAT541) alloy presented the best corrosion performances, with corrosion potential (Ecorr) and corrosion current density (Icorr) values of −1.3309 V and 6.707 × 10−6 A·cm−2, respectively. Furthermore, the corrosion mechanism of Sn is discussed in detail.

“…The elements that can be co-deposited with electroless Ni-P are W, Mo, Cu, Sn, Zn and Co [7][8][9][10][11][12][13]. M. Gholizadeh-Gheshlaghi et al have applied that the addition of WO 3 nanoparticles to Ni-P coatings significantly improved the wear and corrosion resistance of electroless coatings [14]. Z. Rajabalizadeh et al reported the introduction of Cu 2+ in Ni-P to improve the corrosion resistance of nickel-phosphorus coatings [15].…”

In this study, MoS 2 particle and ultrasonic field (UF) were successfully employed to produce Ni-Mo-P, Ni-Mo-P/MoS 2 and UF-Ni-Mo-P/MoS 2 electroless composite coatings on Q235 mild steel. The surface microscopic, microstructures and roughness of the coating were studied using scanning electron microscopy (SEM), energy dispersive spectrometer (EDS), atomic force microscope (AFM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). The corrosion resistance was analysed by Tafel plots and by electrochemical impedance spectroscopy (EIS). The results indicated that compared to a pure Ni-Mo-P coating, the UF-Ni-Mo-P/MoS 2 composite coating exhibited better corrosion resistance. The friction tests showed that MoS 2 particle enhanced the wear resistance of the composite coating. The potential mechanism was that ultrasonic field suppressed the hydrogen gas occlusion and brought about a uniform and dense surface.
