Abstract: A method for simultaneously annealing and applying a coating to a spring includes heating the spring up to a predetermined temperature that exceeds an upper limit of a permissible baking temperature range of the coating. The surface temperature of the spring then allowed to decrease to within the permissible baking temperature range of the coating, and then the coating is applied to a surface of the spring. The coating is then baked onto the surface of the spring while cooling the spring for at least a portion of the baking step. The heating and baking steps together achieve a predetermined low temperature annealing effect in the spring.

Abstract: A method of coating an automotive stabilizer bar having a curved portion and a straight portion includes electrically heating the stabilizer bar such that a surface temperature of the straight portion increases at a rate of 10-30° C./sec and then coating a surface of the electrically pre-heated stabilizer bar.
