摘要： Methods of wearing-in superhard bearing elements over time so that hydrodynamic or near hydrodynamic lubrication of opposed bearing surfaces develops and thrust-bearing apparatuses. In an embodiment, a thrust-bearing apparatus including first and second thrust-bearing assemblies is received or provided. Each thrust-bearing assembly includes a support ring and a plurality of superhard bearing elements mounted circumferentially around the support ring. The superhard bearing elements of each thrust-bearing assembly are oriented so as to be opposed to one another. The thrust-bearing apparatus is operated so as to wear-in the bearing surfaces of both thrust-bearing assemblies such that the bearing surfaces of the superhard bearing elements of each thrust-bearing assembly substantially correspond to one another and become very smooth providing for at least near hydrodynamic operation in which a fluid film is present between the bearing surfaces of the first and second thrust-bearing assemblies so as to limit contact therebetween.
