“…The FEG-SEM image of the TiO2 thin film deposited on the AISI 304 (Figure 1b) showed that the film was composed of grains with irregular shapes and different sizes in the tenths of nanometers, resulting in a smooth surface. At an increased magnification (Figure 1c), the AFM image of the TiO2 film topography showed roughness without any curling from the substrate, in agreement with earlier work by the same research group [38]. It can be seen from Figure 1b that the film was smooth, with a roughness of 4.35 nm, and densely covered the substrate.…”

Titanium dioxide (TiO2) thin films are widely used in transparent optoelectronic devices due to their excellent properties, as well as in photocatalysis, cosmetics, and many other biomedical applications. In this work, TiO2 thin films were deposited onto AISI 304 and AISI 316L stainless steel substrates by atomic layer deposition, followed by comparative evaluation of the mixture of anatase and rutile phase by X-ray diffraction, Raman maps, morphology by SEM-FEG-AFM, and adhesion of the films on the two substrates, aiming to evaluate the scratch resistance. Raman spectroscopy mapping and X-ray diffraction with Rietveld refinement showed that the films were composed of anatase and rutile phases, in different percentages. Scratch testing using a diamond tip on the TiO2 film was employed to evaluate the film adherence and to determine the friction coefficient, with the results showing satisfactory adherence of the films on both substrates.

“…It was observed, when compared with the control sample (Figure a), that the bare Al 2024 specimen (Figure Ia and IIa) submitted to the test had a higher incidence of corrosion point formation throughout the sample area, presenting many small‐sized yet deep points of corrosion, while in the DLC coated samples, only a very few and discreet points of corrosion on the film were present (Figure Ib and IIb). A possible explanation, for the presence of corrosion points over surface of DLC coated specimens after the tests are: (a) the pre‐existing points of corrosion on substrates with may cause a poor punctual adhesion of the DLC coat over it, (b) dust shadows and pores on the films that can act as corrosion nuclei, (c) a solution attack on the silicon interlayer through cavities, cracks, holes, and crevices due to the film thin thickness …”

“…To prevent and improve the corrosion resistance in surface materials in direct contact with fuel in the fuel system of the aircraft, storage tanks, distribution pipelines, aluminum alloys coated with diamond‐like carbon (DLC) films were tested in several situations with aviation fuel medium. The DLC films are widely used as engineering materials on an industrial scale in several applications due to its chemical inertia, high corrosion resistance, low friction coefficient, and high wear resistance . In addition, some features can be added to the films during the deposition process through nanoparticles doping.…”

In aircraft and storage fuel tanks, many environmental corrosion factors can be present, which can cause breakdown to the passive film of aluminum causing severe localized corrosion. Aiming to a solution to this problem, diamond-like carbon (DLC) films were deposited on substrates Al 2024-T3, Al 5052-H32, and Al 6061-T6. The substrates with and without DLC films were submitted to a corrosive immersion test with aviation fuel Jet-A1 and AVGAS 100LL. The surface morphology from aluminum substrates with and without DLC films was analyzed before and after 7 and 30 days of corrosive immersion tests by SEM. The adhesion of the DLC films was evaluated according to the ASTM-C1624 scratching test standard, and the optical profilometry was used to measure the thickness and roughness. Silver nanoparticles were also added in DLC films samples due to its antibacterial properties to check the stability and resistance against corrosive fuel medium. The results indicated an improvement of corrosion resistance just with DLC films. The silver nanoparticles did not present any advantages in this corrosion protection, and the aluminum alloys suffered more corrosion than when protected by DLC films.
