Environmental durability of protected silver mirrors prepared by plasma beam sputtering APPLIED OPTICS Folgner, K. A., Chu, C., Lingley, Z. R., Kim, H. I., Yang, J., Barrie, J. D. 2017; 56 (4): C75-C86

Abstract

Various overcoat layers have been developed to protect silver mirrors from tarnish and corrosion. However, the mechanisms by which these protective layers improve mirror durability are not fully understood. Mixed flowing gas exposure was used to investigate the corrosion behavior of plasma beam sputtered silver mirrors with different adhesion layer materials. A small amount of nickel in the adhesion layer had a significant impact on the silver-dielectric interface. Additionally, lateral transport of silver was found to be an important factor in the corrosion process. Better stability at all layer interfaces is suggested to improve mirror durability.
