Abstract
A condenser that is to be brazed in a radiant energy oven has a significant, localized mass differential which would, without further treatment, create a significant temperature differential across the condenser in the braze oven. This is compensated for, in the method of the invention, by thermally spraying onto the surface of the higher mass portion a rough surface layer of a compatible material that increases the emissivity of that portion sufficiently, relative to the rest of the condenser, to decrease the temperature differential that would otherwise occur.
