Claims
- 1. A process for producing surface material on a part made of Type 60 Nitinol parent material, said surface material being electrically non-conductive hard lustrous, non-stick and integral with the parent material, said surface material having a color from a group of colors consisting of gold, red/purple, blue, silver, and green, said process comprising:a. polishing said part to a smooth finish; b. heating said part to a temperature of about 400° C.-650° C. in a gaseous atmosphere simulating indoor air at room temperature until said part attains said color; and c. allowing said part to cool slowly in said atmosphere to room temperature.
- 2. A process as defined in claim 1, further comprising:d. polishing said cooled part with a fine grit diamond paste on a buffing wheel; and e. repeating steps b-d at least one additional iteration.
- 3. A-process for producing a hard, non-stick, chemically inert and electrically non-conductive surface material on a Type 60 Nitinol part, comprising:heating said part to a temperature of about 400° C.-700° C. in a gaseous atmosphere containing at least about 20% oxygen until said part attains said surface material; and cooling said part to room temperature.
- 4. A process for producing surface material on a part made of Type 60 Nitinol parent material, said surface material being electrically non-conductive, hard lustrous, non-stick and integral with the parent material, said surface material having a color from a group of colors consisting of gold, red/purple, blue, silver, and green, said process comprising:a. polishing said part to a smooth finish; b. heating said part to a temperature of about 400° C.-650° C. in a gaseous atmosphere simulating indoor air at room temperature until said part attains said color; and c. allowing said part to cool to room temperature.
