“…The anticorrosive performance of films can be examined from the corrosion current density (I corr ) obtained from the intersection of the anodic and cathodic Tafel curves (potentiodynamic polarization curves) [19][20][21]. Figure 2 shows the typical potentiodynamic polarization curves of different specimens, f-GSTT i% (i = 0, 5, 10, 15, 20 and 25), in an aqueous 3.5 wt% NaCl working solution at room temperature.…”

Based on silsesquioxanes (SSO) derived from the hydrolytic condensation of (γ-glycidyloxypropyl)trimethoxysilane (GPMS) and titanium tetrabutoxide (TTB), hybrid films on aluminum alloy (AA), film-GPMS-SSO (f-GS) and f-GS-TTB i% (f-GSTT 5%-25% , i = 5, 10, 15, 20 and 25 wt%), were prepared and tested by electrochemical measurements with typical potentiodynamic polarization curves. The I corr values of the samples were significantly lower, comparing with the I corr values of the f-GS, AA and f-GS modified tetraethoxysilane (TEOS) in the previous study, which implies that the TTB 5%-25% (TiO 2 ) additions in the coatings indeed enhance the electrochemical corrosion resistance. Correlations between the film structures and anticorrosion properties were discussed. To validate the corresponding anticorrosion experiment results, different 3D-amorphous cubic unit cells were employed as models to investigate the self-diffusion coefficient (SDC) for SO 2 , NO 2 and H 2 O molecules by molecular dynamics (MD) simulation. All of the SDCs calculated for SO 2 , NO 2 and H 2 O diffusing in f-GSTT 5%-25% cells were less than the SDCs in f-GS. These results validated the corresponding anticorrosion experiment results.

“…The diffusion of nitrogen into the bulk material produces a continuous hardness profile and provides an optimal support to the hard surface layer. This layer is composed of the faced central cubic δ-TiN and the tetragonal ε-Ti 2 N phases, these both compounds are known for their wear and corrosion resistance [7,8]. The nitrided layer thickness is about 1 to 2 μm [9], and the roughness of the surface remains almost the same one after nitriding treatment.…”

“…TiN coatings are used for protection purposes on different kinds of substrate materials due to their hardness and corrosion resistance [1,2]. However, the corrosion resistance of monolayer physical vapour deposited (PVD) TiN lms is poor due to imperfections within the layer such as microcracks, pores, and pinholes and the columnar microstructure of the coating [3].…”

Ti/TiN multilayer lms with a few multilayer periods and a total sub-µm thickness were deposited on AISI 304 stainless steel substrates by ion coating deposition technique. To investigate the eect of hydrogen treatment on the corrosion behavior of the multilayers, some of the samples were hydrogen treated after deposition of the rst and/or the second Ti interlayer.14 N(d, α1) 12 C nuclear reaction and the Rutherford backscattering spectrometry were used to obtain the atomic composition proles and thickness of Ti/TiN layers. Nuclear reaction analysis conrmed the presence of two separable TiN layers of comparable thickness on the surface and in depth of the two-period multilayers. These techniques were used to determine the thickness of individual Ti and TiN layers and revealed that the stoichiometry of TiN layers was approximately Ti:N=1:1. Hydrogen depth prole in the prepared samples was obtained by elastic recoil detection analysis. It was found that a remarkable volume of hydrogen was uptaken by the Ti layer in the hydrogen treated samples. The TiN (200) diraction peak in the X-ray diraction pattern was observed with dierent intensities depending on the sample preparation parameters. The corrosion behavior of the multilayers was studied by means of potentiodynamic polarization in 0.5 M NaCl solutions. It was found that the hydrogen treatment of Ti interlayer could potentially improve the corrosion properties of the Ti/TiN layers.
