Claim:
1. A method comprising: delivering a first all-metal wire to an arc point, the first all-metal wire having a first electrical polarity therein; delivering a second all-metal wire to the arc point, the second all-metal wire having a second electrical polarity therein that is opposite to the first electrical polarity; transmitting a propelling gas through the arc point to propel heated material created by the arcing of the first all-metal wire and the second all-metal wire at the arc point to a surface to be coated, wherein the transmitting of the propelling gas includes transmitting a combustion-based gas; and controlling at least one of a voltage of the arc point, a current of the arc point, a volume of the propelling gas, a pressure of the propelling gas and a distance between the arc point and the surface to create a porous metal coating on the surface.
