Abstract
Highly reflective surfaces, e.g. for headlight reflectors for automotive vehicles can be made by low temperature arc vapor deposition from a mixed metal electrode in which the electrode consists of a mixture of powders of a reflective or relative low melting metal and a ceramic forming high melting metal. The deposit is formed under conditions in which the mixed metals are fully reacted on deposition so that the coating is not susceptible to oxidation in use and requires no protective coating.
