“…Te choice of materials and application techniques played a crucial role in determining the level of protection against corrosion. Chromium 20 nickel [7,8], FeCoCrAlNiTix (x: molar ratio, x 1/4 0.5, 1.0, 1.5, and 2.0) [9], tungsten carbide and chromium carbide [10], TiNbMoMnFe high entropy alloy coating [11], sample 316L austenitic stainless steel [12], nanomodifed silicon-based composite coating [13], tube-ftting nuts made of AISI [14], Mg-X alloys (X = Mn, Sn, Ca, Zn, Al, Zr, Si, Sr) [15], titanium nitride [16], arc sprayed aluminum coating [17], Fe 66 Cr 10 Nb 5 B 19 metallic glass coating [18], and titania coated α-Al 2 O 3 platelets [19] are some of the examples. Based on the discussion, it is found that ceramic composite coatings are good for use against corrosion.…”

Almost every metal and alloy corrodes when used in high-temperature applications. To combat this problem, ceramic coatings on the metals can be deposited for better thermal and corrosion behavior. The present study applies an alumina-titania (Al2O3-TiO2) ceramic coating to the stainless steel (SS) surface using a detonation spray process. The surface of the coated SS is probed by optical microscopy (OM), scanning electron microscopy (SEM), and X-ray diffraction (XRD). The clear differences between coated and uncoated SS have been observed based on the SEM images. The XRD pattern indicates that the Al2O3-TiO2 coating on SS has been successfully deposited. The hardness of coated and uncoated SS surfaces is determined by using the Micro Vickers hardness tester, which claims that the hardness of the SS surface has decreased after coating. Salt spray tests were used to examine the corrosion behavior of coated and uncoated SS after 12 and 24 hours. After 12 hours, no corrosion was observed on the SS. After 24 hours, however, significant corrosion of uncoated SS is observed, and the coated SS shows negligible corrosion. Based on the study, it is claimed that an Al2O3-TiO2 coating on SS has improved its corrosion behavior significantly.
