L'alliage ternaire Ni-W-P et ses films composites MoS2 ont été obtenus avec succès sur de l'acier à faible teneur en carbone par la technique de dépôt chimique. La concentration de tungstate de sodium dans le bain a été modifiée pour obtenir des dépôts de Ni-W-P contenant différentes teneurs en W et P. Le composite Ni-W-P-MoS2 a été obtenu avec une concentration appropriée de tungstate de sodium dans le bain de placage. Ces dépôts ont été caractérisés par diffraction des rayons X (XRD), microscopie électronique à balayage et spectroscopie XRD à dispersion d'énergie....

The development in human life style and society implicating depletion of natural resources which are non-renewable because of drastic demand in energy. There are many simultaneous consequences like increased global temperature, pollution w.r,t. air, water and others. Adding to this, improved living standards of ours demands immediate requirement for efficient devices for electrical energy conversion and storage. The popular means for this are electrochemical supercapacitor, batteries for the purpose of storage and solar cells for conversion of electrical energy.

Die stromlose ternäre Ni-W-P-Legierung und ihre MoS2-Verbundschichten wurden erfolgreich auf kohlenstoffarmen Stahl durch stromlose Beschichtungstechnik erhalten. Die Natriumwolframatkonzentration im Bad wurde variiert, um Ni-W-P-Ablagerungen mit verschiedenen W- und P-Gehalten zu erhalten. Ni-W-P-MoS2-Verbundwerkstoffe wurden mit einer geeigneten Konzentration von Natriumwolframat im Beschichtungsbad erhalten. Diese Ablagerungen wurden mittels Röntgenbeugung (XRD), Rasterelektronenmikroskopie und energiedispersiver XRD-Spektroskopie charakterisiert. Das Korrosionsverhalten wurde mittels...

In this contribution, it is tried sketch different types of thin film fabrication technologies in general. Technological details of fabrication of thin films employing electroless method are discussed in detail, with their principles. Also, the analytical methods to characterize the deposited think films are presented here. In this view, this collection is very significant for the researchers who are interested in designing thin films aiming for specific applications.

Corrosion inhibitors are the chemically active molecules which on adsorption protect the thin films or substrate materials from corrosion. The corrosion protection efficiency of the molecules adsorbed, can be studied by adopting several experimental procedures. Conventionally followed and most reliable technique is weight loss method. The instrumental techniques include, Potentiodynamic polarization or Tafel plots, Electrochemical impedance spectroscopy and Chronoamperometry. The theoretical technique which stands extraordinary is Quantum mechanical methods which involves the theoretical...
