Ruhl, H K

A method is provided for applying a gold ink coating to a thermocouple sheath which includes the steps of electropolishing and oxidizing he surface of the thermoouple sheath into liquid gold ink, and finally heat curing the coating. The gold coating applied in this manner is highly reflective and does not degrade when used for an extended period of time in an environment having a temperature over 1000{degrees}F. Depending on the application, a portion of the gold coating covering the tip of the thermocouple sheath is removed by abrasion.
