Modern ideas about pitting corrosion of corrosion-resistant steels and alloys

Pitting Corrosion Behaviour of New Corrosion-Resistant Reinforcement Bars in Chloride-Containing Concrete Pore Solution

In this study, the pitting behaviour of a new corrosion-resistant alloy steel (CR) is compared to that of low-carbon steel (LC) in a simulated concrete pore solution with a chloride concentration of 5 mol/L. The electrochemical behaviour of the bars was characterised using linear polarisation resistance (LPR) and electrochemical impedance spectroscopy (EIS). The pitting profiles were detected b...

[Dental alloys and corrosion].

Jedan od osnovnih zahteva koji se postavlja za sve stomatološke materijale jeste da su neškodljivi za ljudski organizam i (primum non nocere) i zatim da ne deluju nadražajno ili toksičko na oralna tkiva i organizam u celini. Oni takođe moraju biti niske alergijske aktivnosti i bez štetnog delovanja na bolesnike i osoblje koje njima rukuje. Stomatološke nadoknade ostaju u ustima dug vremenski pe...

Tarnish Resistance, Corrosion and Stress Corrosion Cracking of Gold Alloys

Tarnishing, corrosion and stress corrosion cracking (SeC) of gold alloys are related phenomena. They present problems when they occur in gold jewellery, dental gold alloys and electronic devices. They are exploited, however, in the depletion gilding and finishing of gold jewellery; and in the extraction, refining and fire assaying of gold. There is still much that is not known about these pheno...

Corrosion of Metals and Alloys

Although all metals are subjected to the general oxidation reaction (I), the tendencies to ionize differ from metal to metal. When two metals are exposed to an aquenous environment and release electrons according to reaction (I) , an electric potential is induced the standard value of which can be measured when the metals are in 1-molar solutions of their own salts at a predetermined temperatur...
