They are found naturally and were the first three elements known to man. and reflectivity, thin films are similar to bulk alloys. S. This work deals with a physical and chemical surface characterization of quaternary 18K, 14K, and 9K gold alloys and pure polycrystalline gold substrates. Assumptions and definitions of the model include (1) an elemental metal target has sputter yield s m; (2) target sputtering is due only to the inert working gas; (3) compounds sputtered from the target with sputter yield S c are deposited as molecules; (4) a uniform ion-current density (j) flows over the target area (A t); (5) the collecting substrate surface. Sputtering is one method of the PVD (Physical Vapor Deposition. Only few studies report on the creation of. 00 Printed in Great Britain. Technologies that produce fine-grained targets that deliver uniform thin film coatings.
