Abstract
A method of fabricating a high-temperature bobbin for a solenoid or other electrical assembly includes the step of providing a bobbin configured for use in the assembly. The bobbin is coated with an anti-oxidation composition and an anti-corrosion composition to produce an oxidation/corrosion resistant bobbin. The oxidation/corrosion resistant bobbin is coated with an electrical insulating composition that is resistant to corona discharge at or below a predetermined voltage threshold to produce an insulated and oxidation/corrosion resistant bobbin. The anti-oxidation composition, the anti-corrosion composition, and the electrical insulating composition can withstand temperatures of subzero up to temperature greater than 1000° F.
