Effect of Third Element of Addition on Corrosion Resistance of Ni-Cr alloys Aiming Dental Application
(Brazilian Chemical Soc, 2015-09-01)
Taking into account the large number of existing alloys in national and international markets as well as the variety of elements of addition, in this work different experimental compositions of Ni-Cr-X (X = Ta, Mo, W, Nb, ...
Influence of the heat treatment in the electrochemical corrosion of Al-Zn-Mg alloys
(1992-06-01)
The localized corrosion of Al-(5.03%)Zn-(1.67%)Mg-(0.23%)Cu alloys and high purity Al has been studied using electrochemical techniques, optical microscopy, SEM and EDX. The samples were previously submitted to different ...

Corrosion of dental amalgams: electrochemical study of Ag-Hg, Ag-Sn and Sn-Hg phases
(Elsevier B.V., 2001-08-15)
Dental amalgams, formed by reaction of mercury with a powder alloy containing mainly Ag, Sn, Cu and Zn, have a complex metallurgical structure which can contain up to six phases. Their observed corrosion is thus a complex ...
Use of Electrochemical Tests for Assessment of the Effect of Erosive Particle Size on the Erosion-Corrosion Behaviour of AISI 304L Austenitic Stainless Steel.
(Dot Editoração Eletrônica & Multimídia,São Carlos, 2016)
The degradation of AISI 304L stainless steel under static corrosion, liquid impingement and corrosion-erosion was studied using polarization curves. Static corrosion and liquid impingement tests were performed in 3.5% NaCl ...
Corrosion protection of steel by volatile corrosion inhibitors: Vapor analysis by gas-diffusion microextraction and mass loss and electrochemical impedance in nacl deliquescence tests
(2020-10-01)
A new methodology using gas-diffusion microextraction (GDME) was developed for the analysis of volatile corrosion inhibitors (VCIs). The evaluation of the inhibition efficiency and corrosion rate (ν) was performed by NaCl ...
Estudio de los procesos de corrosion de una aleacion metalica de cobre usada en odontologia
(1997-01-01)
Corrosion phenomena in a dental copper-based alloy are experimentally studied using electrochemical techniques. Two heating sources, torch and induction, were used in the casting experiments. In the corrosion essays, the ...
