Abstract: An article formed of a metal alloy is covered at least partially with a metal hydride and a shell metal to form an assembly. Load is applied to the assembly and the assembly is heated. The shell metal deforms around the article and the metal hydride and forms a gas proof seal. The metal hydride thermally decomposes to form hydrogen gas. At least a portion of the hydrogen gas dissociates and moves as monoatomic hydrogen into the article. The metal alloy can be a zirconium metal alloy, the metal hydride can be a zirconium metal hydride, and the shell metal can be substantially copper.

Abstract: A novel peg apparatus adapted for mounting onto various axles types (e.g. bicycle wheel, conveyor systems, internal machine parts). The device provides either fixed or roller action as preferred by the user. The roller action affords enhanced operating performance and safety in terms of end user satisfaction in each area of potential use. The peg includes an outer sheath made of one of a number of an industrial grade plastic which rotates around the threaded, fixed, mandrel and glides over various surfaces or, which may be locked in a static position to provide a skidding, or “grinding” effect.
