Abstract
Depositing pure aluminum and aluminum alloy coatings onto substrates using directed vapor deposition (DVD) method is presented herein. The aluminum alloys have decreased environmental impact both due to their composition and due to the use of DVD process with no hazardous precursors or waste. Corrosion resistance of DVD deposited aluminum and aluminum alloys is effective for protection of steel substrates. The invention includes the use of the DVD technique to apply aluminum and/or aluminum alloy coatings effective for corrosion protection; the use of plasma-activated DVD to enhance the density of aluminum and aluminum alloy coatings deposited at low substrate temperatures; the use of multi-source evaporation to control composition of aluminum alloys during DVD deposition; the application of aluminum and/or aluminum alloy coatings onto NLOS substrates can be used for corrosion protection.
