Abstract
Provided are bearing assemblies including one or more substrate assemblies, such as thrust bearing assemblies. The substrate assemblies include a bearing element fixed to a substrate. The bearing elements are formed from a thermally stable material such as a ceramic-bonded diamond composite. Methods for manufacturing the bearing assemblies are also provided.
Claims13
A method of manufacturing a bearing assembly comprising at least one substrate assembly, the method comprising:
- providing a substrate having one or more recesses;
- applying a composition comprising an epoxy into each of the recesses;
- inserting at least one bearing element comprising a ceramic-bonded diamond composite into each of the recesses to obtain a wet substrate assembly;
- placing a bottom alignment plate into a pneumatic press;
- stacking the wet substrate assembly onto the bottom alignment plate;
- optionally placing a separator material on top of the wet substrate assembly;
- placing a top alignment plate on top of the wet substrate assembly with or without the separator material therebetween;
- pressing the wet substrate assembly with the pneumatic press at a pressure of from 0.2 to 0.8 psi Megapascal (MPa) for a period of from 5 to 15 seconds;
- removing the pressed wet substrate assembly;
- and
- curing the wet substrate assembly for 24 hours to obtain the at least one substrate assembly.
