A method of coating an article wherein the method includes placing a large number N of non-industrial stock pieces in a vacuum chamber where N is a function of the cost of each stock piece, generating a plasma about the stock pieces, and supplying a current to the stock pieces at a level tailored to sufficiently coat each of the plurality of stock pieces with ion from the plasma and wherein the current level depends on the number N of stock pieces.

1. A method for coating an article, the method comprising:placing a plurality of N stock pieces into a vacuum chamber; generating a plasma of energetic ions around the plurality of N stock pieces using a pulsed RF power; and supplying a pulsed current to the stock pieces at a level to sufficiently coat each of the plurality of N stock pieces with the ions from the plasma, wherein the level of the pulsed current depends on the number N of stock pieces, wherein the pulsed RF power and the pulsed current are synchronized with each other.
