“…In engineering industries, steel plays a major role in transportation, gas turbines, aerospace, household utensils, and structural applications due to their durability under various environments and intrinsic characteristics such as strength, corrosion resistance, formability, high toughness, and excellent weldability [ 1 ]. Among the variety of steels, grade 410 Stainless Steel (SS410) is commonly used for the fabrication of dental and surgical equipment, bearings in aircraft industries, and nuclear applications due to its favorable properties such as high tensile strength, hardness, fatigue resistance, wear resistance, and creep behavior [ 2 ]. High strength and ductility properties are required in materials to meet the current industrial application.…”

“…On the sliding pin surface, MML is formed and is primarily made of wear debris, iron oxides, and other components. This layer protects against material peeling and coating degradation [43,44]. The SWR of Al 2 O 3 coated samples showed 29.76% and the annealed sample exhibited a 57.84% reduction in the SWR compared to the substrate at lower sliding velocity (0.5 m s −1 ).…”

In the present work, a low-carbon steel substrate was coated with Al2O3 and TiC using self-propagating high temperature synthesis. The synthesized coatings were annealed at 450oC for 2-6 hrs. The characteristics of the substrate, coated, and annealed samples were examined, including microhardness, wear resistance, and corrosion resistance. A pin-on-disc tribometer was employed to conduct the wear test by varying the load, sliding velocity, and distance. The impact of these factors on the wear rate and worn surface morphology was then examined. Further, corrosion resistance was evaluated using electrochemical corrosion testing with 3.5 wt.% NaCl as electrolyte. Results showed that Al2O3 and TiC specimens annealed at 450oC for 5 hrs and 4 hrs improved the microhardness by 1.3 and 1.06 times than that of as-coated specimens respectively. The synthesized Al2O3 and TiC coatings showed an abrasive wear mechanism at higher loads and tribolayer formation was observed at higher sliding velocity and distances. The corrosion and wear resistances of the samples were found as follows: substrate< Al2O3 coated < TiC coated < Al2O3 annealed < TiC annealed. The Al2O3 and TiC ceramic coatings were found to improve wear and corrosion resistance having potential applications in cement, petrochemical, and marine industries.

“…The use of laser cladding to apply an Al 0.5 CoCrFeCuNi HEA coating onto an AZ91D magnesium-based alloy has resulted in a notable enhancement of its corrosion resistance [30]. A recent investigation indicates substantial enhancements in the mechanical, and tribological characteristics of SS410 subjected to friction stir processing and reinforced with AlBeSiTiV HEA, in comparison to the base plate that underwent the processing [31].…”

In the realm of advanced materials research, high entropy alloys (HEAs) have emerged as a dynamic and rapidly evolving field, their potential can be further harnessed by developing HEA coatings on specific substrate materials. In this study, equiatomic AlBeSiTiV lightweight HEA (LWHEA) was successfully synthesized through the precise technique of mechanical alloying (MA). Subsequently, this innovative HEA coating was applied to the SS316 substrate using atmospheric plasma spray (APS). The microstructure of the synthesized HEA revealed a prominent FCC phase, with the coating having an average thickness of approximately 150 µm. Notably, the coated and coated annealed samples displayed improved microhardness of 985±13, and 1100±15 HV which was five and six times respectively that of the substrate. Electrochemical and hot corrosion tests were conducted on the substrate, coated, and coated annealed samples. The outcomes shed light on the profound impact of annealing in mitigating the corrosion rate as the porosity of the coated annealed samples was reduced to 2.53% which resulted in a significant reduction in corrosion rate when compared to coated samples. Hot corrosion tests demonstrated mass loss in the substrate due to the formation of iron oxide and subsequent spallation of it while mass gain in the coated and coated annealed samples due to oxide layer formation. Coated annealed samples exhibited lower mass gain in comparison to coated samples, showing reductions of 6% and 3% in Na2SO4/NaCl and Na2SO4/ V2O5, respectively. These findings underscore the immense promise of the annealed coating for applications demanding steadfast protection against corrosive challenges.
