In this work, GeO2 (germanium dioxide) and Sc2O3 (scandium trioxide) were developed as coatings on AZ31 alloy using polymer binder. The coatings were characterized using X-ray crystallography procedure (XRD), infrared spectrum of absorption or emission of a solid procedure (FTIR), Raman spectroscopy procedure, surface examination by FESEM. The corrosion studies were analyzed using a three electrode system in 3.5% NaCl electrolyte. The bare AZ31 alloy showed open circuit potential (Ecorr) of -1.7 V (SCE) and the corrosion current density (icorr) of 3.4 x 10-4 mA/cm2, while the Sc2O3 coated AZ31 alloy exhibited Ecorr of -1.4 V (SCE) and the icorr of 5.4 x 10-9 mA/cm2 and while the GeO2 coated AZ31 alloy exhibited Ecorr of -1.3 V (SCE) and the icorr of 2.59 x 10-9 mA/cm2. The results reveal that the GeO2 coated AZ31 alloy demonstrated higher corrosion resistance than of bare AZ31 alloy and Sc2O3 coated AZ31 alloy.

“…There are numerous approaches to solving the aforementioned issue, one of which is to overlay distinct alloying element [10][11][12]. When compared to overlays made without titanium, the addition of titanium significantly altered the overlay's microstructure, increased surface hardness, and improved wear resistance [13]. In comparison to the blended clads, the satellited clads produced increases in the TiC fraction and deposition efficiency of 29% and 113%, respectively.…”

Friction Coefficient (FC), Rate of specific wear (RSW) of low carbon steel of grade AISI 1018 overlayed with nickel-based MMC plus WC using laser cladding were investigated in this tribological study. Specimens were pressed up on to a rotating steel disc (EN31), experiments were conducted on low carbon steel and low carbon steel overlayed with nickel-based MMC plus WC on a pin-on-disc machine. MMC based on nickel were layered over low carbon steel using the laser cladding process. A set of samples were used in the experiments, which lasted 20 minutes and involved loading conditions of 10N, 20N, 30N, 40N, and 50N with sliding distances ranging from 1000 m to 3000 m. The findings demonstrate how different loads and sliding distances affect the SWR and CoF. Generally, speaking, CoF rises during the rubbing phase and then stays steady for the duration of the test. The obtained results indicate that, for cladded material, the FC and RSW increase with increasing applied load and sliding distance.RSW and FC of Low Carbon Steel overlayed with Nickel based MMC plus WC, which was created using the Laser Cladding Process, decreased. When compared to low carbon steel, the RSW of low carbon steel overlayed with nickel-based MMC plus WC that was created using laser cladding decreased to 31.26%. CoF of low carbon steel covered with MMC plus WC based on nickel, created by laser cladding, is found to be 12.13% lower. To investigate the worn surfaces of the base metal, a Scanning Electron Microscope (SEM) was used, which is low carbon steel and low carbon steel layered with nickel-based MMC plus WC using laser cladding. Two types of samples had worn surfaces with shallow and fine grooves at low loads, and large quantities of cracks at high loads, which raised weight loss.

“…The nickel-based alloy coatings are extensively utilized in the re-manufacturing of key components in extreme fields such as aerospace, shipbuilding, and military equipment due to their excellent high-temperature mechanical properties [1][2][3]. However, the growing demands of modern industry continue to push the limits of component service under severe operating conditions such as high temperatures, high pressures, and heavy loads, resulting in a large number of components failing due to severe wear and fatigue [4][5][6].…”

To reduce the metallurgical defects that are prone to occur in the preparation of nickel-based self-lubricating coatings, a method of process co-optimization for magneto-thermal-assisted laser cladding of nickel-based self-lubricating coatings is proposed in this paper. The laser energy density, preheating temperature, and electromagnetic intensity are selected as input factors; the prediction models of coating dilution rate, porosity and microhardness are established by the CCD test method; the interactive effects of the magnetic-thermal-assisted cladding process on the coating response are analyzed, and the optimal process parameter combinations are obtained by using the optimization method of MOPSO-AE-TOPSIS. Finally, the coatings under the parameters are successfully prepared. The results show that the optimal process parameter combinations obtained are laser energy density of 56.8 J/mm2, preheating temperature of 350 °C, electromagnetic intensity of 49.1 mT, and the error of the experimental results with this parameter is less than 3% from the algorithm optimization results. When the microstructure of unassisted and magneto-thermal-assisted fields are analyzed by comparison, it is found that the tissues are more homogeneous and finer, and the distribution of graphite is more homogeneous, which proves the effectiveness of the optimization method.
