SAE 1045 steel/WC-Co/Ni-Cu-Ni/SAE 1045 steel joints prepared by dynamic diffusion bonding: Microelectrochemical studies in 0.6 M NaCl solution
(Pergamon-Elsevier B.V. Ltd, 2009-12-30)
Corrosion of SAE 1045 steel/WC-Co/Ni-Cu-Ni/SAE 1045 steel interfaces was investigated in 0.6 M NaCl solution using an electrochemical microcell, which enables local electrochemical characterization at the micrometer scale. ...
Cold spray aluminum–alumina cermet coatings: effect of alumina content
(Springer, 2018)
Deposition behavior and deposition efficiency were investigated for several aluminum-alumina mixture compositions sprayed by cold spray. An increase in deposition efficiency was observed. Three theories postulated in the ...
Influence of the indium concentration on microstructural and electrical properties of proton conducting NiO-BaCe0.9-xIn xY0.1O3-δ cermet anodes for IT-SOFC application
(2013-06-25)
Optimization of the major properties of anodes based on proton conductors, such as microstructure, conductivity and chemical stability, is yet to be achieved. In this study we investigated the influence of indium on the ...
TG/DTA-MS evaluation of methane cracking and coking on doped nickel–zirconia based cermets
(Budapest, 2014)
Cermet materials based on metallic nickel and cubic zirconia are the key material for applications on solid oxide fuel cells and high temperature water electrolysis. The main advantage is the possibility of direct feeding ...
Stability, characterization and functionality of proton conducting NiO-BaCe0.85-xNbxY0.15O3-delta cermet anodes for IT-SOFC application
(Elsevier B.V., 2014-10-05)
There are many of properties of anodes based on proton conductors, like microstructure, conductivity and chemical stability, which should be optimized. In this work we were dealing with the influence of niobium on the ...
Time Resolved DXAS Study on Micro and Nano NiO/Ce0.9Gd0.1O1.95 Cermets for Intermediate Temperature Solid Oxide Fuel Cells
(Electrochemical Society, 2016-06)
We present a crystallographic, morphologic and redox dynamic study on (60:40) NiO/Ce0.9Gd0.1O1.95 (NiO/GDC) cermets simulating Intermediate Temperature Solid Oxide Fuel Cells (IT-SOFC) anodes in situ conditions. We tested ...
Effects of thickness coating on the electrochemical behaviour of thermal spray Cr3C2-NiCr coatings
(Elsevier B.V., 2002-04-15)
Thermally sprayed HVOF coatings are increasingly being used in industrial applications where high wear and corrosion resistance are needed [1,2]. In this paper, electrochemical ac and de experiments were used in order to ...
Effect of binders and surface finish on wear resistance of HVOF coatings
(MANEY PUBLISHING, 2010)
The high velocity oxygen fuel (HVOF) thermal spray process produces highly wear and/or corrosion resistant coatings. Tungsten carbide with a metallic binder is often used for this purpose. In this work, tungsten carbide ...
