The electrochemical behaviors of eight parent alloys and four post-solder alloys used in dental prostheses were specified in a (pH=7.4; [NaCl]=9g/L)-aqueous solution at 37°C. For each alloy, the free potential was followed during two hours, and a cyclic polarization between the cathodic domain and the solvent’s oxidation was performed. The galvanic corrosion between each parent alloy and its us...

Adhesive resins for precious metals were prepared by adding an adhesion promoting monomer to MMA-PMMA/TBBO resin. Precious metal alloys bonded by the adhesive resin were thermocycled 0, 1,000, 2,000, or 4,000 times in water between 4 and 60 degrees C, and tensile bond strengths were measured. Debonded metal surfaces after the tensile test were analyzed based on an area of cohesive failure. Thre...

Metal alloys consisting of a platinum group metal—ruthenium, rhodium, palladium, osmium, iridium or platinum—and one or more transition metals are important for catalytic reactions in automobiles, chemistry, and petroleum production. In addition, many of the alloys used in aeronautics and electronics contain platinum group metals. Alloys beyond those currently used in these industries could be ...

CaptekTM (Precious Chemical USA Inc., Apopka, Florida) is a new, innovative development in dental materials. It is a dental alloy that can be defined as a composite material because it is internally composed of two different alloys. CaptekTM is a high gold content alloy (88% by weight) and is used in porcelain-fused-to-metal dental crowns and bridges. Composite metals containing metallic matrix...
