  • Thermocouples of enhanced stability
    Patent number: 4834807
    Abstract: A process for oxidation retardation in nickel-base thermocouple alloy comprises the step of initial heat-treatment of thermoelement wires at high temperatures in an atmosphere of very low oxygen partial pressure. The preferred nickel-base alloy is a type K or a type N alloy. The preferred atmosphere is a gas mixture selected from the group consisting of hydrogen/water vapour, and oxygen/argon.
