A specific feature of the CEMS technique is the possibility for nondestructive testing of the surface composition of paintings, ancient coins, and pottery or other valuable objects. Wagner et al. [445] have investigated Celtic gold coins (from the time period 480-15 b.c.) and have shown that the surface of the coins consist of two phases, one of which is strongly eiuiched in gold compared to the bulk composition. [Pg.366]

The bonded assemblies are then subjected to nondestructive tests designed to determine the presence of voids. Some adhesives are formulated to be x-ray opaque in order to simplify void detection. Tapping the surface with a coin will detect very large voids. However, this... [Pg.728]
