Langues : Américain (ame) Catégories : Acier L'acier est un alliage métallique utilisé dans les domaines de la construction métallique et de la construction mécanique.
L'acier est constitué d'au moins deux éléments, le fer, très majoritaire, et le carbone, dans des proportions comprises entre 0,02 % et 2 % en masse1.
C'est essentiellement la teneur en carbone qui confère à l'alliage les propriétés du métal qu'on appelle "acier". Il existe d’autres métaux à base de fer qui ne sont pas des aciers comme les fontes et les ferronickels par exemple.

ZincIndex. décimale : 667.9 Revêtements et enduits Résumé : The influences of the chromate quenching step and the surface chloride contamination levels of galvanized steel on the performance of duplex systems were studied. Steel panels were galvanized in a commercial steel bath adopting three different postdipping procedures. A comparative study of the galvanized steel, both painted and nonpainted, was performed by electrochemical techniques. It was verified that the chloride contamination level of the galvanized steel surfaces is the main cause of duplex system failures. An explanation for the influence of the chromate quenching on the performance of duplex systems was presented. Note de contenu : - Nonpainted HDG panels

Titane -- AlliagesIndex. décimale : 667.9 Revêtements et enduits Résumé : A thermal spray technology high-velocity oxygen fuel (HVOF) was used to deposit NiCoCrAlY as a bond coating between the titanium alloy substrate and top 8 wt% yttria-stabilized zirconia thermal-barrier coating (TBC) deposited by electron beam-physical vapor deposition (EB-PVD). The thermal cycling and isothermal exposure tests were conducted to evaluate the durability of the TBC. Investigations using OM, SEM, EPMA, and XRD revealed that the thermal-sprayed BC makes the TBC more durable in isothermal exposure tests but more short-lived in thermal cycling tests, in comparison to our previous study in which the BC was prepared by EB-PVD. This is because the thermal-sprayed imperfections, such as microcracks and voids, elevate the diffusion resistance and degrade the mechanical properties of the BC, simultaneously. To current TBC systems in which the BC is deposited by HVOF, thermal failure behaviors—such as the formation of the Ti/Al mixture oxides at some individual places in the BC, and the Ti2Ni gaps formed around the BC/substrate interface—were also discussed.

Revêtement métalliqueIndex. décimale : 667.9 Revêtements et enduits Résumé : Thermal metal spraying (TMS) has been around and used extensively for protection of a range of steel structures and components, both large and small for very many years (over 65 in my own experience). My first personal experiences of TMS, both sealed and over painted with various paint systems, goes back to the 1960s when I became the first qualified Paint Technologist to join the British Iron and Steel Research Association (BISRA) and joined a team in the corrosion section of metallurgists, corrosion engineers and chemists.
One of my projects was to research the performance of TMS for my then Manager - john Stanners who together with his colleague Ken Chandler (who ran the Corrosion Advice Bureau at BISRA) were to give a paper to the European Corrosion Conference in the Hague. This project involved examining the test panels at all of the BISRA exposure sites in marine, industrial and rural exposure atmospheres and to report on the performance of the various systems under test, some of which had been exposed for over 10 years at that time.
As part of the exercise to establish the practical performance of TMS coatings, I also visited the workshop of the Great Ouse River Board (GORB) at Kings Lynn together with John Stanners. I then learnt that the GORB had setup its own TMS spray shop for the sluice and floodgate corrosion protection in the GORB area, as long as 1948. The work shop manager showed us four sluice gates around the Kings Lynn area and, although these had been immersed in fenland water and one with a marine salt water environment, the structures had lasted for between 15 and 18 years.Note de contenu : - Incredibly impressed

Revêtement métalliqueIndex. décimale : 667.9 Revêtements et enduits Résumé : Ti:Cu3N thin films were deposited on Si(111), quartz, and glass slide substrates by DC magnetron sputtering in molecular nitrogen ambient. The structural properties of Ti:Cu3N thin films were studied by X-ray diffraction (XRD) analysis. XRD measurements show diffraction band with peaks close to the (100) and (200) diffraction lines of cubic anti-ReO3 structure of Cu3N. The Ti:Cu3N nano-crystalline size is in the range 22–27 nm. Lattice constant expansion reflects Ti incorporation causing the excess nitrogen to occur. Surface morphology shows that the N richness suppresses the grain growth. The optical absorption spectra indicate a remarkable shift to higher energies of the absorption edge due to higher N concentration and quantum size effect. Photoluminescence (PL) measurement shows interstitial N excess and Ti impurity produce shallow and deep levels, respectively. Thermal stability of the Ti:Cu3N films annealed at 300 and 400°C is improved in comparison with that of Ti free Cu3N films.

Revêtement métalliqueIndex. décimale : 667.9 Revêtements et enduits Résumé : The specular gloss of metallic coatings from the automotive industry can be well measured by current glossmeters when the geometry is appropriately chosen from 20°, 60°, and 85° based on the gloss levels observed. However, the measurements are discontinuous and even nonmonotonic at the breakpoints dividing samples into different gloss levels in the whole range, which causes confusion and inconvenience for industry applications. In this study, attempts were made to link the measurements at the three geometries to be continuous monotonically and in the meanwhile to improve the accuracy of estimating visual gloss. A psychophysical experiment based on a magnitude method was carried out to assess the gloss of metallic coatings with different colors and textures. The visually scaled gloss data were compared with spectrophotometric measurements and instrumental specular gloss values under different geometries. With different weighing coefficients for measurements at individual geometries depending on the gloss levels, a model was proposed to describe the visual surface gloss of metallic coatings comprehensively via a practical metric based on the geometry-dependent measurements. In this way, each sample would have a unique overall gloss value highly correlated with its perceptual evaluation over the entire gloss range.
