Strength of glass with vacuum-deposited metal films: Cr, Al, Au and Ag

Fracture strength of acid-etched glass with vacuum deposited metal films is investigated. The strength of the etched glass having an initial value of 1696±39 MN m−2 reduces to 265±10 MN m−2 with 69 nm thick Cr film coating. Al film coating also causes the strength reduction, but the reproducibility of the strength is not found even under strictly controlled evaporation conditions. In ambient air, the strength of Au- and Ag-coated glasses maintains the initial high strength value and slightly increases with film thickness. From strength reduction behaviour of Cr-coated glass and dynamic fatigue characteristics for Ag-coated glass, it is highly probable that rupture of the metal film takes place before fracture of the glass occurs, and the flaw formed in the film propagates under loading into the glass to act as a Griffith crack.
