Abstract
A method of applying a wear-resistant material to a surface of a downhole component for use in subsurface drilling comprises forming a plurality of bearing elements, applying a layer of an electrically conductive, less hard material to each bearing element, and then bonding each bearing element to the surface of the component by welding or brazing to the surface of the component a part of the surface of the bearing element which comprises said less hard material, wherein the layer is of thickness greater than 0.05mm.
Claims21
A method of applying a wear-resistant material to a surface of a downhole component, the method comprising forming a plurality of bearing elements, applying a layer of an electrically conductive, less hard material to each bearing element, and then bonding each bearing element to the surface of the component using one of a welding process and a brazing process to bond to the surface of the component a part of the surface of the bearing element which comprises said less hard material, wherein the layer is of thickness greater than about 0.05mm.
A downhole component having a surface to which a plurality of bearing elements are bonded, each bearing element having previously had a layer of a less hard, electrically conductive material applied thereto, the layer of less hard material having a thickness greater than about 0.05mm.
