  • METHOD AND SYSTEM FOR USING AN IRREVERSIBLE THERMO-CHROMATIC INDICATOR FOR QUALITY ASSURANCE OF A PART SUBJECTED TO HEAT TREATING
    Publication number: 20170130308
    Abstract: A system and method of verifying that a part is heat treated to strengthen the part. The part is marked with a thermo-chromatic composition before heat treating. The part is then heat treated to strengthen the part and change the color of the thermo-chromatic composition to indicate successful completion of the heat treating process. A detector may act to prevent the inclusion of a non-heat treated part in an assembly by disabling an assembly tool. A controller may also provide data related to the completion of the heat treating process to be recorded in a database.
