A system for spraying a coating material to a substrate includes an optical sensor that monitors a thickness, a controller that generates a first signal corresponding to an amount of gas propellant to be heated, a second signal corresponding to a temperature to which the gas propellant is to be heated, a third signal corresponding to an amount of a solid powder composition to be mixed with the heated gas, and a fourth signal corresponding to a distance between the nozzle and the substrate, a first regulator that supplies an amount of gas propellant corresponding to the first signal, a heater that heats the gas propellant to the temperature corresponding to the second signal, a second regulator that supplies an amount of solid powder composition corresponding to the third signal, and an actuator that moves the nozzle corresponding to the fourth signal.

Method and system for fabricating an electrical conductor on a substrate

A method for fabricating an electrical conductor on a substrate by cold spraying includes propelling a solid powder composition that includes copper and highly oriented pyrolytic graphite using a gas propellant, and directing the solid powder composition towards the substrate at a velocity sufficient to cause the solid powder composition to undergo plastic deformation and to adhere to the substrate to deposit the electrical conductor thereon.
