Abstract: Improved methods and apparatus for cross-sectional scanning of parts employ a scanning station in which the focal plane of the scanning apparatus never moves in the vertical direction, i.e., the direction in which the stage of the part/potting combination moves. Distinct steps of material removal and scanning alternate with an intermediate step of moving the part/potting combination in the vertical direction after a surface layer has been removed, thus placing the newly-created surface back into the non-moving focal plane for the next scanning step. A  removal station (not the stage carrying the part/potting combination) repeatedly moves into and out of the field of view of the scanning station between scanning steps. The material removal station is specially configured to remove the desired surface layer of the part/potting combination and the created debris, without requiring the separate environment characteristic of previous commercial applications.

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.
