Résumé : This paper presents, using a specific experimental set-up, the cathodic polarization curves recorded under steady-state and quasi-stationary conditions, for 316L stainless steel, Alloy C-276 and T60 titanium materials, in oxidative chlorinated aqueous media. Measurements were carried out at temperatures and pressures reaching supercritical conditions (400 °C, 28 MPa). The influence of various parameters such as the pH, the nature of materials, the sub- or supercritical state of the medium, was investigated using the determination of the corrosion rate. A hierarchy of the electrochemical behavior of the materials was established as far as the resistance to corrosion of industrial plants is concerned.

Résumé : In order to better constrain the Tertiary reactivation of the different mountain ranges in Central Asia under the influence of the India-Asia collision, we carried out a magnetostratigraphic study along the Kuitun He section on the northern flank of the Tian Shan range. The Kuitun He section is composed of upper Tertiary sediments that were folded in a ramp anticline, then incised by a Holocene river. Sediment deposition was likely coeval with the building of the Tian Shan mountains, which coincided with major climatic change across Central Asia. About 1200 core samples were collected along the 2000-m-thick section, which is composed mainly of sandstone and conglomerate. In the laboratory, we performed both thermal and AF demagnetization, as well as magnetic mineralogical studies such as IRM, magnetic hysteresis, Curie point analyses, etc. Preliminary results show that magnetite is the main carrier of the magnetic remanence. A tenth of magnetic polarity intervals have been identified along the section. Preliminary correlation of this polarity sequence with the reference curve suggests an age span between 7 and 3 Myr with an average sedimentation rate of about 0.4 mm/yr. The high sedimentation rate can be interpreted in terms of facies migration, which owes to both tectonic and climatic forcing. The overall mean direction shows no significant inclination shallowing as is generally observed in Tertiary sediments throughout Central Asia.

Résumé : In the automotive and aeronautic industries, security is of prime importance and so corrosion prevention is essential. Steel parts were once protected with deposits such as cadmium or zinc-nickel produced using a chromatation treatment but recent environmental directives dictate that these methods are no longer acceptable. Aluminium sacrificial coatings have excellent corrosion behaviour but unfortunately they have poor mechanical characteristics and a fast dissolution rate. The present study investigated a possible solution: alloying the aluminium with a more noble element, chromium, in order to decrease the sacrificial galvanic effect of the deposit and therefore improve its lifetime. The corrosion protection afforded by such coatings in relation to their structure and mechanical properties was investigated. The coatings were produced on carbon steel by a vacuum PVD arc evaporation process at a pilot scale. Intrinsic electrochemical properties were determined on pure materials and on layers deposited on glass strip. Several elaboration configurations (pure as well as composite targets) were investigated. In most cases the coatings were stratified and composed of pure aluminium and numerous hardened AlxCry intermetallic phases. Chromium enrichment of aluminium based coatings induces not only a beneficial hardening effect on the surface characteristics (> 700 HV) but also significantly improves the corrosion behaviour of the coated pieces (increasing lifetime by up to three times compared to pure Aluminium).

Résumé : Sediments on the Namibian Margin in the SE Atlantic between water depths of ∼1000 and ∼3600 m are highly enriched in hydrocarbon-prone organic matter. Such sedimentation has occurred for more than 2 million years and is geographically distributed over hundreds of kilometers along the margin, so that the sediments of this region contain a huge concentrated stock of organic carbon. It is shown here that most of the variability in organic content is due to relative dilution by buried carbonates. This reflects both export productivity and diagenetic dissolution, not differences in either water column or bottom water anoxia and related enhanced preservation of organic matter. These observations offer a new mechanism for the formation of potential source rocks in a well-ventilated open ocean, in this case the South Atlantic. The organic richness is discussed in terms of a suite of probable controls including local wind-driven productivity (upwelling), trophic conditions, transfer efficiency, diagenetic processes, and climate-related sea level and deep circulation. The probability of past occurrences of such organic-rich facies in equivalent oceanographic settings at the edge of large oceanic basins should be carefully considered in deep offshore exploration.
