The as-prepared samples were characterized by the scanning electron microscope, transmission electron microscope, X-ray diffraction analysis, and Fourier transform infrared spectrometer. The release of Ce3+ ions was detected by the immersion test and the solution analysis method. The anti-corrosion performance of the coatings was evaluated by the corrosion test, open-circuit potential analysis, the potentiodynamic polarization curve, and electrochemical impedance spectroscopy in 3.5 wt% NaCl aqueous solution. The results showed that the Ce3+-PANI/MMT composite had better anti-corrosion effects along the coating defects.

Nitrure de titaneIndex. décimale : 667.9 Revêtements et enduits Résumé : TiN-matrix coating was prepared by reactive high velocity oxygen fuel (HVOF) spraying on carbon steel based on the self-propagating high temperature synthesis (SHS) technique in air. The phase composition, structures, and properties of TiN-matrix coating were analyzed using XRD, EDS, SEM and Vickers microhardness equipment. The anti-corrosion property in nearly neutral 3.5 w t% NaCl electrolytic solution was measured. The Weibull distribution of Vickers microhardness at different loads and their linear fitting were analyzed. The apparent fracture toughness of the coating was also calculated. The coating is composed of main phases (TiN, TiN0.3), minor phases (Ti2O3, TiO2), and porosity. The anti-corrosion property of an HVOF-sprayed TiN-matrix coating in electrolytic solution is superior to that of AISI 316L stainless steel. The microhardness values from 1137HV0.05 to 825HV1 are relatively high and have indentation size effect (ISE). With the increment of m, which increases with the increment of applied load, the microhardness values are more concentrated. The average value of apparent fracture toughness Kic is 4.62MPa}. m1/2. It is higher than that of reactive plasma sprayed (RPS) TiN coating, which reflects the good toughness of a TiN-matrix coating deposited by reactive HVOF spraying.

Notwithstanding, with ever-increasing temperatures and pressure and chemical resistance requirements in oil and gas environments, the demands placed upon linings are becoming more stringent.
This article investigates whether the performance of these linings could be enhanced by first abrasive blasting the steel substrate and then providing a subsequent application (and removal) of a unique chemical reagent to remove deleterious sulfide contaminants, improve lining performance in aggressive immersion service conditions and potentially extend the life-cycles of the applied linings.
Accelerated laboratory investigations were carried out on a set of reagent-treated, and untreated, carbon steel test panels. Sets of panels were lined with a three-coat, thin-film solvent-borne epoxy novolac coating or a single coat solvent-free, thick-film polycyclamine-cured epoxy.
Characterization of the lining performance, the lining-steel interface and efficacy of the sulfide removal reagent was achieved using autoclave (NACE-TM0185), electrochemical impedance spectroscopy (EIS), scanning electron microscopy (SEM/EDX) and X-Ray diffraction (XRD).Note de contenu : - CANDIDATE SURFACE DECONTAMINATION TECHNOLOGY CHEMICAL CLEANING

SiliconesLes silicones, ou polysiloxanes, sont des composés inorganiques formés d'une chaine silicium-oxygène (...-Si-O-Si-O-Si-O-...) sur laquelle des groupes se fixent, sur les atomes de silicium. Certains groupes organiques peuvent être utilisés pour relier entre elles plusieurs de ces chaines (...-Si-O-...). Le type le plus courant est le poly(diméthylsiloxane) linéaire ou PDMS. Le second groupe en importance de matériaux en silicone est celui des résines de silicone, formées par des oligosiloxanes ramifiés ou en forme de cage (wiki).Index. décimale : 667.9 Revêtements et enduits Résumé : The corrosion of carbon steel (CS) is a disastrous threat to artificial engineering in harsh environments, such as underground mines and seawater environments. Herein, we employed facile one-step electrodeposition to prepare a superhydrophobic intertwining structure on a CS surface in an effort to alleviate corrosion. Sophisticated characterization methods suggested that La tetradecanoate formed during the electrodeposition process via an electrochemical reduction reaction. Silicone lubricant acted as the insoluble phase and was infused into the superhydrophobic matrix to yield a biomimetic slippery lubricant-infused surface (LIS) due to the capillary effect from the superhydrophobic intertwining structure to the lubricant phase. Using natural seawater, salt spray and sulfate-reducing bacteria (SRB) suspension as the harsh media, LIS shows excellent corrosion resistance to the underlying metal compared with bare CS and the superhydrophobic surface covering CS because the oil phase acts as a barrier to inhibit the penetration of corrosive species. For the LIS sample after seawater immersion for 20 d, the Icorr was approximately 2 orders of magnitude smaller than that of the bare CS. In addition, after a 5.0 wt% salt spray test for 20 d, the |Z|0.01 Hz of the LIS surface was ca. 3 orders of magnitude larger than that of CS. Furthermore, when immersed in an extremely harsh SRB suspension for 15 d, the |Z|0.01 Hz of LIS was ca. 3 orders of magnitude larger than that of bare CS because LIS can dually prohibit the bioattachment of SRB and avoid the penetration of the highly corrosive metabolite. Thus, the LIS was proven to have prominent anticorrosion properties in harsh corrosive environments. Note de contenu : - Preparation of SHS and LIS onto CS

Revêtement en phase solvant:Peinture en phase solvantIndex. décimale : 667.6 Peintures Résumé : The paper analyzes the performance of solventborne paint systems applied on carbon steel and hot-dip galvanized steel in a wide range of atmospheric exposures. The study has involved paint systems exposure for 3.5 years in eight natural atmospheres. The atmospheric conditions cover from temperate rural climates to tropical severe marine and Antarctic coastal regions. The paint systems included several alkyds formulated with a variety of pigments (anticorrosive and barrier), epoxies, chlorinated rubber, and zinc-rich (ethyl silicate and epoxy). It has been concluded that in rural and urban atmospheres alkyd systems afford equivalent anticorrosive protection of steel to the epoxy/polyurethane system. The toxic red lead pigment may be replaced in long linseed-oil alkyd primer paints by non-toxic pigments, such as a mixture of micaceous iron oxides (MIO) and black iron oxides or zinc phosphate, without affecting the anticorrosive properties of the paint system. In aggressive atmospheres (industrial, marine), paint systems including zinc-rich primers or applied on galvanized steel must be used, especially in surface regions with coating faults (scribes).
