RESISTANCE HEATING ALLOYS AND SYSTEMS FOR …

When heated, resistance heating alloys form an oxide layer on their surface, which prevents further oxidation of the material. To accomplish this function the oxide layer must be dense and resist the diffusion of gases. It must also be thin and adhere to the metal under tem- perature fluctuations.
