A method for forming a connection such as an electrical connection, to a fibre material electrode element comprises moving a length of the fibre material relative to a pressure injection stage and pressure impregnating by a series of pressure injection pulses a lug material into a lug zone part of the fibre material to surround and/or penetrate fibres of the fibre material and form a lug strip in the lug zone. The fibre material may be a carbon fibre material and the lug material a metal such as Pb or a Pb alloy. Apparatus for forming an electrical connection to a fibre material electrode element is also disclosed.

The present disclosure provides downhole tools, methods for three dimensional printing hardfacing on such downhole tools, and systems for implementing such methods.

A mold is used to form a solder joint to join the distal end of the guidewire to a wire coil. The mold has a cavity that can have different configurations so that the solder joint can be any of bullet shaped, micro-J shaped, cone shaped, truncated cone shaped, or have a textured surface.

Disclosed herein is a method for applying a liquid metal on a surface of an object that is selected from the group consisting of a heat-emitting surface and a heat-conducting surface. The method includes applying the liquid metal onto the surface, and applying a force to the liquid metal using a tool to destroy cohesion of the liquid metal, followed by moving the tool back and forth to apply the liquid metal on the surface.

Method of fabricating structures, such as parts for use in nuclear power generation systems, are described herein. A representative method of fabricating a part for a nuclear reactor system includes additively manufacturing the part as a monolithic structure from a wire formed of an oxide dispersion strengthen (ODS) material, which includes an oxide material dispersed within a metal material. Specifically, the method can include directing a beam of thermal energy toward the wire to melt the wire, and permitting the melted wire to cool and solidify to form the part such that the oxide material remains substantially dispersed within the metal material. By maintaining the dispersion of the oxide material within the metal material, the ODS material can retain a good creep resistance, wear-resistance, corrosion resistance, and/or other ODS material property at elevated temperatures—even after fabrication.

A contact layer is formed by a deposition method on an inner surface of a first metal element by a centrifuging process, and preferably includes an inner layer of copper alloy and an outer layer of tin alloy. Such a contact layer is used in an articulation joint including a first metal element having a surface provided with the contact layer, and a second metal element with a second surface. The first and second elements are relatively movable such that first and second surfaces slide against each other.
