A fracture fixation system particularly useful for bones of the hand and foot is disclosed. The system uses curved shape-memory alloy (e.g., Nitinol) wires that have a predetermined radius of curvature to accommodate different sized bones. These shape-memory alloy wire forms can be inserted into phalanx, metacarpal or metatarsal bones via a percutaneous technique. The technique uses small skin incisions; a specialized drill guide that has holding K-wires to maintain fixation of the drill guide to the bone so that it does not lose the insertion point; a specialized drill as well as a specialized wire cutter and advancement tool to make sure that the level of the wire is below the level of the outer cortical bone. Shape-memory alloy (e.g., Nitinol) based wires with a pre-bent curve have an advantage over the typical standard K-wire in that they can spring back to their predetermined memory shape when inserted into the intramedullary canal of the bone and heated, i.e., a more aggressive curve. By increasing their bending or flexion to increase the arc of curvature, this allows fixation points for the wire, essentially locking it to bone.

Ferritic nitrocarburized surface treatment of cast iron brake rotors providing oxidation resistance, good braking performance and absence of distortion. Machined brake rotors are pre-heated, then immersed into a high temperature molten nitrocarburizing salt bath for a first predetermined dwell time. After removing the brake rotors from the nitrocarburizing salt bath, the brake rotors are directly immersed into an oxidizing salt bath at a lower temperature than the nitrocarburizing salt bath so that the brake rotors are thermally quenched. After a predetermined second dwell time in the oxidizing salt bath, the brake rotors are removed therefrom and further cooled to room temperature, either by water application thermal quenching or slow cooling in air. A fixture provides stable holding the brake rotors with a minimum of contact during placement in the salt baths.
