The snap-link was exposed to a karst cave environment. Each part of the security set was observed by means of an optical and scanning electron microscope with EDS analyzer. Corrosion products were analyzed by X-ray diffraction (XRD). The snap-link failure was caused by an inappropriate heat treatment and exposure to a permanently humid atmosphere. %U http://versita.metapress.com/content/9h885xw017524512/?p=7979bcf751a649598681cbb1049e69be&pi=4
