  • Palladium-cobalt based alloys for dental prestheses including porcelain fused to metal
    Publication number: 20080070192
    Abstract: An alloy s provided for dental prostheses including porcelain fused to metal (PFM) restorations. The alloy is grey in color with an oxide coating for bonding porcelain to the oxidized cast alloy substrate. The alloy has suitable mechanical properties for cast prostheses and for the support of the porcelain and is readily polished to a bright sheen. The alloy is based on a palladium-cobalt binary system, has a coefficient of thermal expansion (CTE) in the range of about 14.0 to 15.3 and may include one or more of the following additive metals: aluminum, boron, chromium, gallium, lithium, rhenium, ruthenium, silicon, tantalum, titanium, and tungsten.
