  • Adsorption of the prototypical organic corrosion inhibitor benzotriazole on the Cu(100) surface
    Item type: Journal Article

    Corrosion Science
    The interaction of benzotriazole (BTAH) with Cu(100) has been studied as a function of BTAH exposure in a joint experimental and theoretical effort. Scanning tunnelling microscopy (STM), X-ray photoelectron spectroscopy (XPS), high resolution electron energy loss spectroscopy (HREELS) and density functional theory (DFT) calculations have been combined to elucidate the structural and chemical characteristics of this system. BTAH is found to deprotonate upon adsorption on the copper surface and to adopt an orientation that depends on the molecular coverage. Benzotriazolate (BTA) species initially lie with their planes parallel to the substrate but, at a higher molecular coverage, a transition occurs to an upright adsorption geometry. Upon increasing the BTAH exposure, different phases of vertically aligned BTAs are observed with increasing molecular densities until a final, self-limiting monolayer is developed. Both theory and experiment agree in identifying CuBTA and Cu(BTA)$_2$ metal-organic complexes as the fundamental building blocks of this monolayer. This work shows several similarities with the results of previous studies on the interaction of benzotriazole with other low Miller index copper surfaces, thereby ideally completing and concluding them. The overall emerging picture constitutes an important starting point for understanding the mechanism for protection of copper from corrosion.

  • Steel dissolution in carbonate environments
    Item type: Journal Article
    Furcas, Fabio E.; Mundra, Shishir; Somaini, Federico; et al. (2025)
    Corrosion Science
    The electrochemical dissolution of carbon steel exposed to aqueous carbonates stands as one of the main causes for the deterioration of carbon capture, utilisation and storage facilities, pipelines, hydrocarbon refining equipment and reinforced concrete structures. To unlock the full potential of carbon capture applications and ensure the structural integrity of existing chemical processing and civil infrastructure, a thorough understanding of the mechanism of steel dissolution is needed. Here, we leverage advancements in thermodynamic modelling calculations to re-evaluate the stability of the [Figure presented] -C-H2O system. In combination with electrochemical measurements under controlled hydrodynamic conditions, we show that the electrochemical dissolution in the form of the iron carbonate complex [Figure presented] is solely controlled by the pH dependent carbonate equilibrium. The resultant kinetic mechanism is in full agreement with the experimentally obtained dissolution rates and the thermodynamic calculations. We envision the here used methodology to be applied to the dissolution of other metals exposed to a broad range of electrolyte compositions.
  • Corrosion of ultra-high-purity Mg in 3.5% NaCl solution saturated with Mg(OH)2
    Item type: Journal Article
    Cao, Fuyong; Shi, Zhiming; Hofstetter, Joëlle; et al. (2013)
    Corrosion Science
    Corrosion was evaluated for ultra-high-purity magnesium (Mg) immersed in 3.5% NaCl solution saturated with Mg(OH)2. The intrinsic corrosion rate measured with weight loss, PW = 0.25 ± 0.07 mm y−1, was slightly smaller than that for high-purity Mg. Some specimens had somewhat higher corrosion rates attributed to localised corrosion. The average corrosion rate measured from hydrogen evolution, PAH, was lower than that measured with weight loss, PW, attributed to dissolution of some hydrogen in the Mg specimen. The amount of dissolution under electrochemical control was a small amount of the total dissolution. A new hydride dissolution mechanism is suggested.

  • Visualizations of the carbon interphase influence on the ablated fracture morphology of carbon/carbon composites at pore scale
    Item type: Journal Article
    Ji, Ritian; Wang, Hui; Qin, Feifei; et al. (2022)
    Corrosion Science
    An ablation model considering reaction kinetics of carbon interphase in carbon/carbon composites is proposed. The proposed model also comprehensively considers the couple of the oxygen diffusion, the movement and reaction heat at the carbon-air interface, the aerodynamic heat on the ablation layer, and the heat conduction in the carbon solid. The pre-exponential factor and the apparent activation energy in the Arrhenius formula is put forward. Simulated ablation morphologies agree well with experimental results. The aerodynamic heat accelerates the formation of reaction morphology. The apparent activation energy coefficient has a greater effect on reaction morphology compared with the pre-exponential factor coefficient.
