On the Corrosion Resistance of Lead and Lead Alloys (2nd Report). On the Corrosion Resistance of Lead, Lead Antimony Alloys and Lead Tin Alloys

Stationary Lead-Acid Batteries With Selenium Alloys

Until ten years ago the grids of lead-acid batteries were usually made of lead-antimony alloys containing 5-11 wt. % antimony. The necessary mechanical strength and castability are easily achieved with this content of antimony. However, the unavoidable corrosion of the positive grid liberates antimony from the grid, which proves to be both unfavorable as well as unfavorable with respect to batt...

Corrosion 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...

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...
