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...
متن کاملCorrosion Resistance of Dental Alloys
Metals and metallic alloys are unavoidable materials in everyday dental use for the making of fillings, cast cores and post systems, individual crowns, implantants’ suprastructures, dentures and orthodontic devices. They still belong to the vital materials in dentistry. Applied alloys in a mouth are exposed to the influence of chemical, biological, mechanical, thermal and electrical forces whic...
متن کاملTarnish 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...
متن کاملCorrosion behavior of metals and alloys in marine-industrial environment.
This work deals with atmospheric corrosion to assess the degrading effects of air pollutants on ferrous and non-ferrous metals and alloys, which are mostly used as engineering materials. An exposure study was conducted in the Tuticorin port area located on the east coast of South India, in the Gulf of Mannar with Sri Lanka to the southeast. Common engineering materials, namely mild steel, galva...
متن کامل[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...
