Tests for Applying Coatings Based on Aluminum and Silver on Alnico Alloys

Abstract

The paper presents preliminary research on the application of coatings by the PVD method. The coatings were deposited on an AlNiCo alloy with a suitably pre-prepared surface. Two different coating materials were used. Coatings based on pure silver and pure aluminum were applied. The tests included the assessment of the influence of the coating deposition time on the final thickness of the coatings. The samples after the deposition process were specially prepared for observation under the microscope. Scanning microscopy examinations made it possible to assess the connections of the obtained coatings with the substrate.
