Using a hybrid helicon-arc ion-plasma reactor, a coating based on aluminium nitride (AlN) is deposited on the steel 3 and aluminium substrates. Regardless of the substrate, it is found that a coating with a thickness of ≅ 2.0 μm is formed during 30 minutes of deposition; increasing the process time to 45 minutes allows to obtain a coating two and a half times thicker (≅ 5 μm). As determined, the selected deposition time does not allow obtaining a coating of stoichiometric composition of AlN on the substrates used. As a rule, a compound with Al excess is formed. As shown, in cases where a plastic material (for example, aluminium) is used as a substrate, the formation of the coating can only be the last technological operation.
Key words: film coatings, microstructure, stoichiometric composition, aluminium, aluminium nitride.
