Bearing with improved wear resistance and method for making same |
摘要 |
A steel bearing member having an erosion resistant surface and a method of making the same is disclosed. The steel bearing member comprising a bearing substrate, a first overlay of hardbanding material having sintered cemented metal carbide pellets in steel and containing hard submicron sized particles, and a second overlay of steel containing hard particles that migrated from the first overlay of hardbanding material during application of the second overlay over the first overlay. A radial bearing member and a method of making the same is disclosed. A composition applied to the bearing substrate to improve the erosion resistance of this surface comprising a steel carrier and carbide pellets composed of submicron hard particles cemented with a metal binder is disclosed.
