Abstract

Aluminum oxide coatings are fabricated in an arc discharge through the reactive thermal anode evaporation of aluminum with intense ion assistance. The effect the bias voltage and ion current density have on the structure and properties of the Al₂O₃ α-phase that forms on a stainless steel substrate with an isostructural Cr₂O₃ sublayer at 600°С is studied.
