摘要
The magnetic performance of a color CRT is optimized by firing ferromagnetic components thereof in an exothermic atmosphere to anneal the components and form a stable black iron oxide layer on a surface thereof. The components are introduced into a furnace having such an atmosphere and the components are heated to a temperature sufficient to initiate pre-oxidation of the surface thereof. The temperature is then increased to optimize the magnetic characteristics of the components and at least partially relieve stress therein. The components are next cooled to a temperature at which the thickness of the stable black oxide layer on the surface of the components is optimized. A CRT is manufactured according to the process described above.
