In the present study, three coatings of Al2O3, Al2O3-13%(TiO2) and Al2O3-40%(TiO2) composite coatings were deposited by the thermally flame spray process. The comparative wear behaviour of the Al2O3-TiO2 coatings has been studied under high temperature levels up to 400°C with the help of a high temperature tribometer at a constant load of 40N. Prior to the tribo-test, the coating morphology and elemental analysis has been examined with the help of field emission scanning electron microscope (FESEM), elemental dispersion spectroscopy (EDS) and X-ray powder diffraction (XRD) techniques. The Mechanical properties have been also analyzed and reported. The results reveal that specific wear rate decreases with an increase in temperature for all the deposited coating except Al2O3 coating at 400°C. The overall friction coefficient of the coatings is decreasing with the increasing temperature. The Al2O3-40%TiO2 coating showed maximum sustainability against wear as well as a low coefficient of friction because of its low hardness and high adhesion properties. The examined worn surface validates the presence of brittle fracture and abrasive wear behaviour mechanism along with the oxidation wear, from room temperature to 400°C.

“…Various preparation methods, including laser cladding [12], surface overlay welding [13], and explosive spraying [14], have been introduced. Thermal spraying, a scalable and cost-effective technique, has found extensive application in engineering for Cr 3 C 2 -NiCr coating fabrication [15][16][17]. However, the inherent defects of thermal spray coatings like micro-pores, micro-cracks, and poor adhesion fail to be fully eliminated, leading to a reduction in their performance [18,19].…”

In this study, Cr3C2-Al2O3-NiCr coatings were prepared on INCONEL 600 alloy surfaces using the supersonic flame spraying technique, followed by a laser remelting treatment. In this way, this study further explored what impacts laser remelting has on coating performance. To this end, optical microscopy (OM), scanning electron microscopy (SEM), and electron backscatter diffraction (EBSD) were employed to carry out microstructural characterization. Energy-dispersive X-ray spectroscopy (EDS) was applied to conduct an analysis of the coatings’ elemental distribution while X-ray diffraction (XRD) was used to determine the coating phases. To measure the microhardness of the coatings, a microhardness tester was applied. In addition, the study investigated the samples’ electrochemical corrosion resistance and friction-wear performance under different surface conditions. According to the results, laser remelting enhanced the coating density, improved metallurgical bonding with the substrate, and optimized the carbide distribution, thereby enhancing corrosion and wear resistance in both air and corrosive media. However, excessive laser power hinders Cr3C2 nucleation, leading to diminished coating hardness and wear resistance in Cr7C3 formation.

“…As a representative technology for thermal spraying, supersonic atmospheric plasma spraying (SAPS) is an improved technique of plasma spraying that combines the advantages of high flame temperature (32,000 K) and fast particle flight speed (240-800 m/s) (Liu et al, 2019a(Liu et al, , 2019b. The metal ceramics prepared by this method exhibit high bonding strength and low porosity (Liu et al, 2019a(Liu et al, , 2019b. The Cr 3 C 2 -NiCr coatings are highly favored for their excellent corrosion resistance, making them widely used in technical fields such as marine engineering (Qin et al, 2019), aviation (Li et al, 2020a) and missile systems (Matikainen et al, 2017) that require highperformance coatings.…”

Purpose Due to the harsh underground environment in coal mining, the surface of hydraulic support columns corrodes severely, resulting in significant economic losses. Therefore, a highly corrosion-resistant coatings is needed to extend the service life of the columns. Design/methodology/approach This study aims to compare the corrosion resistance of ST-Cr3C2-NiCr (sealed treatment Cr3C2-NiCr) coatings with industrially applied chromium plating. The corrosion failure mechanism of the coatings was investigated. Findings The results demonstrated that the ST-Cr3C2-NiCr coatings exhibited excellent corrosion resistance. After sealing treatment, the corrosion potential of Cr3C2-NiCr coatings was −0.215 V, and the corrosion current density of Cr3C2-NiCr coatings was lower than that of the plated parts. Practical implications ST-Cr3C2-NiCr coatings prepared by supersonic atmospheric plasma spraying could provide excellent corrosion resistance in the coal industry. Originality/value The low porosity and the presence of the NiCr phase were crucial factors contributing to the preferable corrosion resistance exhibited by the ST-Cr3C2-NiCr coatings. The corrosive process of the coatings involved layer-by-layer delamination of surface oxide film, sub-surface pitting, formation and degradation of sub-surface passive film, as well as severe block-like delamination.
