Characterization of luminescent samarium doped HfO2 coatings synthesized by spray pyrolysis technique
(IOP PUBLISHING, 2013-01-16)
Electrochemical behavior of thermally sprayed stainless steel coatings in 3.4% NaCl solution
(Elsevier B.V., 2005-03-01)
Four types of stainless steel coatings prepared by a high velocity oxy-fuel spraying system (HVOF) were studied. Differences among coated steels were related to the spraying parameters, which influenced the behavior of the ...
Electrochemical behaviour of thermally sprayed Cr3C2-NiCr coatings in 0.5 M H2SO4 media
(Kluwer Academic Publ, 2002-11-01)
The electrochemical behaviour of coated Cr3C2-NiCr steel in aerated 0.5 M H2SO4 solution was studied by means of electrochemical a.c. and d.c. measurements. A complete structural characterization of the coated steel before ...
Temporal evolution of sulfated zirconia sol-gel during dip coating: Analysis of mass drainage with time-varying refractive index
The formation of sulfated zirconia films from a sol-gel derived aqueous suspension is subjected to double-optical monitoring during batch dip coating. Interpretation of interferometric patterns, previously obscured by a ...
Residual stress mapping in TiN coatings by nanoindentation technique
(Volume 70, Issue 11, November 2012, Pages 1320-1325, 2012-11)
Abstract Titanium nitride (TIN) coatings were deposited on American Iron and Steel Institute (AISI) 410 stainless steel substrates by the cathodic arc physical vapor deposition process, varying the substrate bias voltage ...
Electrochemical behavior of cobalt oxide coatings on cold-rolled steel in alkaline sodium sulfate
(Elsevier B.V., 2002-05-07)
The electrochemical behavior of a coating of cobalt oxide on cold-rolled steel in alkaline sodium sulfate was Studied using the electrochemical techniques of open-circuit potential measurements and electrochemical impedance ...
Localised corrosion assessement of crambe-oil-based polyurethane coatings applied on the ASTM 1200 aluminum alloy
Coatings composed of polyurethanes derived from polyesters of crambe oil and pre-polymer obtained from hexamethylene diisocyanate and castor oil were prepared (1:2 and 1:3, respectively) and applied on the Al alloy 1200. ...
Corrosion resistance evaluation of HVOF produced hydroxyapatite and TiO2-hydroxyapatite coatings in hanks' solution
The electrochemical behavior of HVOF produced hydroxyapatite (HA) and 80HA-20TiO2 coatings were investigated using electrochemical techniques in natural aerated Hanks' solution in the presence and absence of bovine serum ...
Photodesorption and electron trapping in n-type SnO2 thin films grown by dip-coating technique
Thin films of undoped and Sb-doped (2 atg%) SnO2 have been prepared by sol-gel dip-coating technique on borosilicate glasses. Variation of photoconductivity excitation with wavelength and optical absorption indicate indirect ...
