An experimental study has been performed to deposit aluminum powder on steel for corrosion prevention using argon-helium working gases. Experiments were conducted using a Box Statistical Design of Experiment (SDE) approach. A substantial range of plasma processing conditions and their effect on the resultant coating is presented. The coatings were characterized by hardness tests and optical metallography. Coating qualities are discussed with respect to hardness, porosity, surface roughness, deposition efficiency, and microstructure. Attributes of the coatings are correlated with the changes in operating parameters. An optimized coating design predicted by the SDE analysis is presented for the particular application.
