Abstract

In this paper we report Re and Re-NiCr layers obtained by Thermoionic Vacuum Arc (TVA) technique. The films deposited onto copper, glass and ceramic substrates were characterized by XRD and AFM methods. We have found that Re film crystallinity is not dependent on substrate composition while Re-NiCr layer structure strongly depends on the substrate composition. The prepared films were found to be very adherent, pure and smooth providing that TVA is a good method to produce high quality coatings of refractory metals..
