Improving wear and corrosion protection of AISI 304 stainless steel by Al₂O₃-TiO₂ hybrid coating via sol-gel process

Development of TiO2/Nb2O5 Films and Evaluation of Corrosion Prevention in AISI 304

“…homogeneity and crystallinity, with lower roughness and higher corrosion resistance. [13] Gecu and Eraslan [14] and Gecu et al [15] conducted studies similar to the previous research on the deposition of coatings composed of TiO 2 . However, broadening our analysis and integrating new insights into this subject is crucial.…”

“…The results indicated that an increase in the concentration of TiO 2 contributed to a more adherent, continuous, and less porous coating morphology, resulting in improved wear and corrosion resistance. [14,15] Gecu et al [15] followed an approach akin to this research, as it involved the deposition of Al 2 O 3 -TiO 2 coatings on AISI 304 substrates. Polarization and EIS tests were also conducted in a NaCl solution, exposing AISI 304 to an environment containing chloride ions-known for their aggressiveness toward this material.…”

“…Polarization and EIS tests were also conducted in a NaCl solution, exposing AISI 304 to an environment containing chloride ions-known for their aggressiveness toward this material. [15] TiO 2 exists in three allotropes: anatase, rutile, and brookite, with anatase considered the most suitable phase for applications in nanoscale polymorphic films and grains. This phase exhibits high hardness, low chemical reactivity, high refractive index, biocompatibility, nontoxicity, and photoconductive properties.…”
