Abstract
Bearings assemblies are provided that include polycrystalline diamond bearing surfaces that are engaged with opposing, metal bearing surfaces that include more than trace amounts of diamond solvent-catalyst. In the bearings, the opposing bearing surface is slidingly engaged with the polycrystalline diamond bearing surface along a diamond contact area of the polycrystalline diamond bearing surface, and the polycrystalline diamond bearing surface is a continuous surface along the diamond contact area. Also provided are methods of making and using the bearing assemblies.
