PVD Interface Design of Niobium Coatings on Steel Substrates by Cathodic Arc Generated High Energy Ion Bombardment
First published: 27 June 2000
Summary
The present study further investigates the nature of the interfacial region created by Nb ions from the steered cathodic arc source and the influence on the corrosion performance with regard to the average ion energies as well as to the working gas (argon) pressure during etching. The latter parameter is of interest as sufficient high working gas pressures can be beneficial for the stability of the cathodic arc operated at low arc currents when using high melting point materials such as Nb (Tm = 2500°C).
