| titleOfInvention | Fixed-cutter matrix bits with repairable gauge pads |
| abstract | Provided are fixed-cutter matrix bits comprising hardfaced elements on the gauge pads. Also provided are methods of manufacture and using. An example fixed-cutter matrix bit comprises a matrix bit body, a plurality of cutter elements secured at fixed locations to the matrix bit body, and a plurality of gauge pads disposed on the matrix bit body; wherein at least one of the gauge pads includes a hardfaced exterior surface. The hardfaced exterior surface may comprise a material selected from the group consisting of tungsten, niobium, vanadium, molybdenum, silicon, titanium, tantalum, zirconium, chromium, yttrium, boron, carbon, carbides thereof, nitrides thereof, borides thereof, oxides thereof, silicides thereof, and combinations thereof. The hardfaced exterior surface may be fused to the at least one gauge pad during the infiltration process of manufacturing the matrix bit body. |
