“…5 Moreover, a peak appeared at around 690 cm −1 , assigned to the presence of iron oxide/hydroxide (e.g., Fe 3 O 4 and/or γ-Fe 2 O 3 ) in the surface film. 30 A separate X-ray photoelectron spectroscopy (XPS) analysis of such a film has confirmed the existence of Fe 2 O 3 and CeO 2 in the surface layer. The XPS results will be reported elsewhere together with the detailed CRM results.…”

Thin composite films of the mussel adhesive proteins (Mefp-1) and ceria nanoparticles were deposited on substrate surfaces by alternating immersions. The film formation was studied by quartz crystal microbalance with dissipation (QCM-D) monitoring. Both the changes in frequency and dissipation recorded by QCM-D demonstrate buildup of a composite film of Mefp-1 and nanoceria. Micro-and nanostructure and composition of the film on carbon steel were characterized by optical and atomic force microscopy (AFM), electron probe micro analyzer (EPMA) and confocal Raman microspectroscopy (CRM). Optical and EPMA observations of the film show micron-sized aggregates and AFM imaging of the compact and smooth areas reveal the nanostructure. EPMA elemental mapping indicates that the micron-sized aggregates are rich in ceria and Mefp-1, whereas CRM analysis shows the presence of Mefp-1-Fe complexes in the film. Corrosion protection of the composite film on carbon steel was investigated by electrochemical impedance spectroscopy and potentiodynamic polarization measurements in NaCl solution, and compared with Mefp-1 added in the solution as an inhibitor. The measurements show that the composite film provides a higher corrosion resistance compared with Mefp-1 added as inhibitor. The corrosion resistance increases with exposure time and approaches a high level. Corrosion inhibitors are widely used to control corrosion of metallic materials that causes huge economic cost to our society, and even catastrophes due to unexpected failure of metallic constructions and devices. In the past decade, extensive efforts have been devoted to developing new "green" corrosion inhibitors to replace traditional ones that are harmful to human health and ecological systems.1 Filmforming inhibitors based on organic substances that are more "green" for human and environment have attracted considerable attention in recent years. For example, a mussel adhesive protein (MAP), derived from marine mussel Mytilus edulis, has shown a certain inhibition effect on stainless steel.2 In our previous study, Mefp-1, the type of MAP that has been most studied, was shown to exhibit interesting inhibiting properties on carbon steel in NaCl solutions. However, the inhibition efficiency of Mefp-1 is limited since the adsorbed film is not sufficiently compact, and this is particularly a problem for the initial period during which Mefp-1 does not give a significant inhibition effect. 3The adhesive and cohesive properties of MAP are generally attributed to the high content of di-hydroxyphenylalanine (DOPA), 4 which has been reported to form complexes with metal ions 5,6 and metal oxides. Waite et al. have concluded that the DOPA moiety in the proteins serves two important roles in MAP adhesion to many surfacesthe formation of interfacial complexes promoting chemisorption and cross-links. 8,9 In another study of adsorption and corrosion protection of polydopamine based surface films on aluminum alloys, it was concluded that these self-assembled surface films can provide a c...

“…On‐site Raman analysis also is very efficient in identifying the inorganic phases of corrosion layers and patina on metal. Measurements performed on coupons at the laboratory have demonstrated their potential, in particular, for the detection of amorphous or poor crystalline phases hardly detectable by X‐ray diffraction and very detrimental to metal conservation . For instance, the corrosion layer of iron and steel is formed by different iron (oxy‐hydroxides) that acts—or not—as a barrier and provides—or not—a protective ability.…”

Raman microspectroscopy conducted with transportable/mobile instruments allows for the non‐invasive identification of amorphous and crystalline phases of ancient masterpieces and outstanding artworks (objects, paintings and décor, building parts, etc.). Resonance Raman spectroscopy detects chromophore and dye traces. On the basis of examples (enamelled glass and pottery, enamelled metal, patinated/corroded metal, stained glass, sculptures, paintings, pastels, and drawings), this mini review discusses the main parameters (laser and optics choice, experimental procedure, etc.) and shows how phase identification contributes to a better understanding of innovant technology exchanges.

Identification of Corrosion Products on Fe and Cu Metals using Spectroscopic Methods

In this study, the Fourier-transform infrared absorption and the Raman spectroscopies for analysis of corrosion products formed on the Fe and Cu metal surfaces after deposition in the chloride containing solution, were used. The obtained spectral patterns show that main constituent species of the corrosion products for Fe metal sample is lepidocrocite, while in the case of Cu surface there is formed mainly paratacamite. The obtained results confirm that application of vibrational spectroscopic methods is precise tool for identification and analysis of the corrosion products.
