Abstract
A method of manufacturing a heater having a heating element, an insulator and a spring is disclosed. The method includes forming a spring from an annealed superalloy material, heat treating the spring after forming, positioning the heating element in contact with the insulator, and biasedly engaging the spring with the insulator to maintain contact between the insulator and the heating element.
