A composite electrode includes a sheet of carbon nanotubes (CNTs) and an electrically conductive metal. The sheet of CNTs include a surface region where carbon atoms are available. The metal is chemically bonded to at least a portion of the carbon atoms whereby a metal carbide is defined.

A tool for pulling a lockwire, which extends around the intersection of mating cylindrical surfaces within a case and extends tangentially from between these surfaces through an opening in the case to a termination at the exterior of the case, has a body which mates at one side with conforming exterior elements of the case adjacent to the opening. The body extends tangentially of the surfaces from the one body side and the case opening. The tool has an extraction rod extended from the case opening through a square passage within the body. The lockwire is of rectangular cross section with opposite surfaces which are parallel to the axis of the mating case surfaces, and the lockwire termination has a hole extending between these surfaces. One rod end portion is of square cross section fitted to the passage and ends in jaws disposed to fit oppositely over these lockwire termination surfaces so that bores in the jaws are aligned with the lockwire hole. An opening in the body is disposed for the insertion of a pin through this opening and into the bores and the hole to connect the rod and the lockwire. The opposite rod end portion is screw threaded and bears a nut outwardly of the body. With this structure, appropriate rotation of the nut draws the rod away from the case and withdraws the lock wire tangentially from between the mating cylindrical surfaces within the case.

A process for making a Teflon/aluminum composite includes providing Teflon powder and aluminum powder wherein a size of Teflon particles is about 7 to 12 times a size of aluminum particles; mixing the Teflon powder with the aluminum powder on about a 3 to 1 weight basis; pressing the mixed powder into a shape at a pressure ranging from about 6000 psi to about 16000 psi; and then sintering the pressed shape.
