    Abstract

    The history and corrosivity of the LaQue Center for Corrosion Technology, Inc.'s “Kure Beach” atmospheric test site has been reviewed in brief. Stainless steel and other Ni-containing alloy test specimens from a number of earlier investigations remain exposed in the site's “museum area”, the oldest of these dates to December 1940. The appearance of these and other 1940, 1950, and 1960 vintage specimens was documented in early 2001. The performance of various test specimens are reviewed, and in some cases compared with that reported previously. Gloss and surface roughness measurements were used as non-subjective tools to assess the current state of reflectivity and luster, and corrosion incurred after periods of up to 60 years in the marine environment. Both alloy composition and original surface finish influenced the performance of different grades. The opinions of earlier researchers appear to have been validated many years later.
