ABSTRACT:
The journal and/or pilot bearings of a rotary cone earth boring bit are constructed to include alternating areas of wear resistant materials and anti-galling materials. The bearing matrix is formed by compressing a powdered alloy in the shape of the desired bearing element. The bearing matrix is sintered, thereby forming a porous bearing element. An anti-galling material is infiltrated into the porous matrix of the bearing element and the bearing element is hardened. The resulting bearing element includes areas of wear resistant materials and areas of anti-galling materials.
