Abstract:
Polycrystalline diamond compacts for use in artificial joints achieve reduced corrosion and improved biocompatibility through the use of solvent metal formulations containing tin and through the control of solvent metal pore size, particularly in inner layers of the compact. Solvent metal formulations containing tin have been discovered which provide sintering ability, part strength, and grind resistance comparable to levels achieved by using CoCrMo solvent metals. It has been discovered that limiting the solvent metal pore size in the diamond layers minimizes or eliminates the occurance of micro cracks in the solvent metal and significantly reduces the corrosion of the compact as manifested by the release of heavy metal ions from the compact. Polycrystalline diamond compacts which utilize both the solvent metal formulations containing tin and the control of pore sizes achieve significantly reduced corrosion and improved biocompatibility compared to prior art polycrystalline diamond compacts.

Abstract:
A plated substrate comprises a plating layer disposed outwardly from a substrate. The substrate comprises a substrate material, where the substrate material comprises a metal. The plating layer comprises a plating material and blocking particles. The plating material comprises grains, and the blocking particles are disposed within interstices between the grains. The blocking particles are scattered substantially uniformly throughout at least a portion of the plating layer, and contribute to formation of boundaries.
Abstract:
The present invention relates to a joint (10) that includes a first member (11) to be jointed, a second member (12) to be jointed and a jointing layer (13) located between the first member (11) and the second member (12). The jointing layer (13) is made of Sn metal and a metallic material with a melting point higher than the melting point of the Sn metal. The present invention relates also to a method of joining this first member (11) to the second member (12).

Abstract:
The present invention relates to an electrocatalytic coating and an electrode having the coating thereon, wherein the coating is a mixed metal oxide coating, preferably ruthenium, titanium and tin or antimony oxides. The coating uses water as a solvent that provides for a smoother surface than alcohol based solvents. The electrocatalytic coating can be used especially as an anode component of an electrolysis cell and in particular a cell for the electrolysis of aqueous chlor-alkali solutions.
Abstract:
Electrical connectors incorporate a composite coating of molybdenum disulfide and a metal, preferably tin, for one or both of the contact surfaces of the electrical connector. The coating provides for a low coefficient of friction, low contact resistance, and good electrical conductivity, as well as good mechanical properties. The coating also reduces the insertion force of the electrical connectors, thereby increasing the number of possible terminal pairs and/or reducing terminal bending and breakage for a manually mated connector. The coating can be deposited on copper, tin-plated copper, tin alloy-plated copper or other metallic substrates, using any of several physical vapor deposition methods.
