More Information
Summary:Downhole tool bearings are provided with diamond enhanced materials. The diamond enhanced materials comprise diamond grains in a matrix of tungsten or silicon carbide or a silicon bonded diamond material. A brazed diamond grit or diamond particles coated with a reactive braze may be utilized for bearing applications. Bearing rings for use in downhole tools may be formed at least in part with the diamond enhanced material. In one embodiment, the bearing rings may be used in a positive displacement motor. In additional embodiments, the bearing rings may be used in a submersible pump.
