ABSTRACT:
A very thin gold coating (e.g., 270 to 3,500 Angstroms) is vapor deposited on the surface of a nickel substrate. A short radiant energy pulse from a laser having a pulse length of about 130 nanoseconds is directed at the coated surface to melt portions of the gold coating and the nickel substrate therebelow. The energy pulse is removed to permit the melted material to resolidify as an alloy with a high concentration of gold at the surface thereof.
