Embrittlement in archaeological silver artifacts: Diagnostic and remedial techniques

Abstract

Figure 2. The types of corrosion of high-silver-content archaeological silver: (a) a metallograph of intergranular corrosion (Werner 1965), (b) a metallograph of interdendritic corrosion (Scott 1996), (c) an SEM metallograph of corrosion along slip lines, deformation twins, and segregation bands (Wanhill et al., 1998), and (d) an SEM fractograph of crystallographic fracture due to corrosion along slip lines and deformation twins (Wanhill et al., 1998).
