This book was released on 1995 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: LA PRESENTE ETUDE TENTE D'APPORTER QUELQUES ELEMENTS NOUVEAUX A LA CONNAISSANCE DE L'ELECTROZINGAGE EN MILIEU ALCALIN SUR ELECTRODES DISPERSEES, METHODE DE PROTECTION DE L'ACIER LARGEMENT EMPLOYEE DANS L'INDUSTRIE DE LA BOULONNERIE-VISSERIE. LES PIECES DE VISSERIE SONT GENERALEMENT FABRIQUEES PAR FRAPPE A FROID A PARTIR D'UN FIL MACHINE D'ACIER FAIBLEMENT ALLIE. ELLES SUBISSENT DE CE FAIT, PLUSIEURS TRAITEMENTS MECANIQUES THERMIQUES, CHIMIQUES ET/OU ELECTROCHIMIQUES AVANT ELECTRODEPOSITION PROPREMENT DITE ET SONT EXPOSEES A DES SOURCES D'HYDROGENE POUVANT ENTRAINER DES RISQUES DE FRAGILISATION DU SUBSTRAT. IL EST GENERALEMENT ADMIS QUE LA FRAGILISATION PAR L'HYDROGENE DEPEND DE LA COMPOSITION CHIMIQUE ET DE LA MICROSTRUCTURE DU METAL ET LES CONDITIONS DE CHARGEMENT ELECTROLYTIQUE. PAR CONSEQUENT, NOUS AVONS ORIENTE LA RECHERCHE VERS LA RELATION LIANT LA PENETRATION DE L'HYDROGENE DANS LE SUBSTRAT ACIER ET LA GAMME D'ELECTROZINGAGE. CE TRAVAIL COMPREND TROIS PARTIES: LE DECAPAGE ACIDE, L'ELECTROZINGAGE ET LA PENETRATION DE L'HYDROGENE DANS LE METAL. DANS UN PREMIER TEMPS, NOUS MONTRONS LA RELATION ENTRE L'EFFICACITE DE LA SEQUENCE PREPARATION, L'ETAT METALLURGIQUE ET LA COMPOSITION DES ACIERS ET LA REACTIVITE DE L'INTERFACE METAL/SOLUTION. PUIS, LE ROLE DE BRILLANTEURS INDUSTRIELS UTILISES POUR LES ELECTROLYTES CYANURES OU NON-CYANURES SUR LA MODIFICATION DE LA MORPHOLOGIE DES REVETEMENTS ET SUR LE RENDEMENT FARADIQUE EST DECRIT. ENFIN, NOUS DETERMINONS PAR UNE METHODE ELECTROCHIMIQUE SENSIBLE ET SPECIFIQUE LA VITESSE DE PENETRATION DE L'HYDROGENE A TRAVERS UNE MEMBRANE D'ACIER. LES RESULTATS MONTRENT QUE LE MODELE DIFFUSIONNEL GENERALEMENT PROPOSE DANS LA LITTERATURE NE S'APPLIQUE PAS DANS LE CADRE DE NOS ECHANTILLONS. UN AUTRE MODELE EST DISCUTE EN TERMES D'APPROCHE PHYSIQUE. CE TRAVAIL MET EN EVIDENCE L'IMPORTANCE DES PROPRIETES METALLURGIQUES DU SUBSTRAT SUR LA DIFFUSION DE L'HYDROGENE DANS LES ACIERS ET SUR LA REACTIVITE DE L'INTERFACE

COOK and published by . This book was released on 1984 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'EMPLOI DE L'ELECTRODE A DISQUE TOURNANT PERMET D'ECLAIRCIR LES MECANISMES PRINCIPAUX DE CORROSION ET DE PASSIVATION DU CUIVRE SUIVANT LE REGIME HYDRODYNAMIQUE. EN MILIEU ALCALIN NON SULFURE, UN MECANISME DE NUCLEATION ET CROISSANCE A PARTIR D'ESPECES ADSORBEES EST PROPOSE POUR LA FORMATION DE CU::(2)O, CE QUI CONDUIT A UNE PREMIERE ZONE DE PASSIVITE. A DES TENSIONS PLUS ELEVEES, DES IONS CUIVRIQUES SONT GENERES EN DEUX ETAPES DE TRANSFERT MONO-ELECTRONIQUE. UNE SECONDE ETAPE DE PASSIVATION EST ATTRIBUEE A LA FORMATION D'UNE COUCHE MINCE DE CU(OH)::(2), SUIVIE DE LA REGENERATION D'UNE COUCHE INTERMEDIAIRE DE CU::(2)O. EN MILIEU ALCALIN SULFURISE, L'ADSORPTION D'IONS SULFURES MODIFIE CONSIDERABLEMENT LA REPONSE ELECTROCHIMIQUE DE LA SURFACE DU METAL, ET ON N'OBSERVE PAS DE VRAIE PASSIVITE, SURTOUT POUR UNE ELECTRODE EN ROTATION. DES MODELES D'ENSEMBLE DES PHENOMENES DE CORROSION ET DE PASSIVATION DU CUIVRE DANS CES MILIEUX SONT PROPOSES

Book Synopsis Faecal Sludge Management by : Linda Strande
Download or read book Faecal Sludge Management written by Linda Strande and published by IWA Publishing. This book was released on 2014-08-15 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized sanitation technologies for urban areas is gradually changing, and is increasingly being considered as long-term, sustainable options in urban areas, especially in low- and middle-income countries that lack sewer infrastructures. This is the first book dedicated to faecal sludge management. It compiles the current state of knowledge of the rapidly evolving field of faecal sludge management, and presents an integrated approach that includes technology, management, and planning based on Sandecs 20 years of experience in the field. Faecal Sludge Management: Systems Approach for Implementation and Operation addresses the organization of the entire faecal sludge management service chain, from the collection and transport of sludge, and the current state of knowledge of treatment options, to the final end use or disposal of treated sludge. The book also presents important factors to consider when evaluating and upscaling new treatment technology options. The book is designed for undergraduate and graduate students, and engineers and practitioners in the field who have some basic knowledge of environmental and/or wastewater engineering.
Book Synopsis Chemical Thermodynamics of Neptunium and Plutonium by : Robert J. Lemire
Download or read book Chemical Thermodynamics of Neptunium and Plutonium written by Robert J. Lemire and published by Elsevier. This book was released on 2001-08-26 with total page 876 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unlike earlier books in this series, this review describes the selection of chemical thermodynamic data for species of two elements, neptunium and plutonium. Although this came about more by circumstance than design, it has allowed for a more consistent approach to chemical interpretation than might have occurred in two separate treatments. It has also drawn attention to cases where the available data do not show expected parallels, and where further work may be useful to confirm or refute apparent differences in the behaviour of neptunium and plutonium.
