Al2O3 and TiO2 atomic layer deposition (ALD) were employed to develop an ultrathin barrier film on copper to prevent water corrosion. The strategy was to utilize Al2O3 ALD as a pinhole-free barrier and to protect the Al2O3 ALD using TiO2 ALD. An initial set of experiments was performed at 177 °C to establish that Al2O3 ALD could nucleate on copper and produce a high-quality Al2O3 film.

This work presents the corrosion protection behavior of A304 stainless steel in an acidic medium by using coatings based on polyaniline+TiO2 composite material. The influence of parameters such as concentration of aniline, TiO2 content, and pH of the solution were investigated. The coatings which had been deposited by cyclic voltammetry on substrates of A304 steel were then characterized by Comparison of chemical stability and corrosion resistance The wide applications of ultrathin group IV metal oxide films (TiO 2 , ZrO 2 and HfO 2 ) probably expose materials to potentially reactive etchants and solvents, appealing for extraordinary chemical stability and corrosion resistance property. In this paper, TiO 2 ultrathin films were deposited on Si at 200 °C while ZrO<SUB>2</SUB> and HfO<SUB>2</SUB> were grown at 250 °C to fit their growth Corrosion Behavior of Coatings of ium Nitride and It is well known that titanium nitride (TiN) coatings produced by physical vapor deposition (PVD) have a limited corrosion resistance, as a result of their intrinsic porosity. Some attempts have been made to improve corrosion resistance, by such measures as increasing film thickness. The deposition of Ti interlayers are known to improve not only corrosion resistance but also adherence, probably because
The corrosion resistance obtained by fitting the impedance spectra also reveals that the TiO2 films provide good protection for stainless steel against corrosion in sodium chloride solution. Corrosion Resistance of Stainless Steel Coated by ium The polarization curves of stainless steel were determined by using electrochemical workstation. The results showed that the corrosion resistance of stainless Corrosion behavior of ZrO2TiO2 nanocomposite thin films Oct 17, 2016 · Ceramic film has attracted a lot of attention in the last few decades due to its wear resistance, corrosion resistance and resistance to high temperature. This paper describes the characterization of preparing of zirconia (ZrO 2 )titania (TiO 2 ) composite films on the stainless steel through a method of dip-coating in solgel solution.
Jan 16, 2019 · he composite TiO2/CeO2 samples possess deep cracks which evidently favor the attacks in corrosion medium. Ceria and titania coatings deposited on stainless steel have zero weight loss in corrosive medium. The TiO2 coatings could also effective protect carbon steel, while the TiO2/CeO2 and CeO2 coatings exhibited lower corrosion resistance. Effect of Argon-Oxygen Mixing Gas during Magnetron The corrosion resistance of TiO 2 coatings was evaluated by potentiodynamic polarization test using a PARSTAT 4000. The measurement was conducted using a conventional three-electrode electrochemical cell in 3.5 wt. % NaCl solution:a saturated calomel electrode (SCE) as the reference electrode, a carbon as the counter electrode (CE), and the samples with 1 cm 2 exposed area as the working electrode Effects of N-Doped TiO2 Thin Films on Corrosion Resistance Results showed that N-doped TiO 2 thin films had a nanosized anatase structure, with a uniform and compact surface. In artificial saliva and 1.23% acidified phosphate fluoride solutions, the as-prepared thin films lowered the corrosion current density and increased the polarization resistance, indicating improved corrosion resistance.
