USE OF TUNGSTEN CARBIDE TUBE ROD TO HARD-FACE PDC MATRIX

摘要

A hardfaced infiltrated matrix downhole tool and a method for hardfacing such items is provided. The hardfaced infiltrated matrix downhole tool includes a body, an intermediate base coat coupled to at least a portion of the surface of the body, and a hardfacing material coupled to at least a portion of the intermediate base coat. The body is composed of at least a carbide material and an infiltrating binder material. The intermediate base coat bonds to the surface of the body and to the hardfacing material. The method includes obtaining an infiltrated matrix downhole tool, applying and bonding the intermediate base coat to at least a portion of the surface of the infiltrated matrix downhole tool, and applying and bonding the hardfacing material to at least a portion of the intermediate base coat.
