2005 F.N. Speller Award Lecture:Atmospheric Corrosion—Research, Testing, and Standardization

Abstract

The atmosphere forms the most widespread corrosive environment. Corrosion protection and damage caused by atmospheric corrosion are important burdens on society's economic life. The Czech specialists have actively participated in solving theoretical and engineering problems of atmospheric corrosion and protection against it over the last 50 years. Results from these studies are summarized, with special attention being paid to the presentation of goals and the results of worldwide modern international programs. The International Standardization Organization (ISO) technical committee "Corrosion of Metals and Alloys" was active in developing standards for atmospheric corrosion testing and atmospheric corrosivity classifi cation. An approach to defi ne these standards and the use of information on corrosivity of the atmosphere for selection of materials and protective measures is presented. KEY WORDS: atmospheric corrosivity classifi cation, atmospheric corrosion testing, copper and bronze monuments, dose/response functions, integrated database, weathering steels 0010-9312/05/000147/$5.00+$0.50/0 © 2005, NACE International CORROSION SCIENCE SECTION 724

Evaluation of 4-Year Atmospheric Corrosion of Carbon Steel, Aluminum, Copper and Zinc in a Coastal Military Airport in Greece

“…In order to succeed on these goals, a proper understanding of the local corroding system is required. Consequently, in order to assess corrosion damage on aeronautical materials and the infrastructure in a military airport, located in a distance of approximately 0.2 km from the seashore, a long-term outdoor experiment employing the reference metals (commercially pure aluminum 1050, unalloyed carbon steel, zinc and copper) was undertaken, using a methodology based on ISO and ASTM Standards methodology [6-9,21-35] and a literature review on relevant sources [36][37][38][39][40][41][42][43]. The effects of pollutants and meteorology on the corrosion of the reference metals at the rural and coastal atmosphere of the Pachi Military Airport (LGMG), after a 4-year period of outdoor exposure and the anticipated corrosion rate of these metals after 30 years of outdoor exposure are presented.…”

Rust Formation Mechanism on Low Alloy Steels after Exposure Test in High Cl− and High SOx Environmen

“…The corrosivity and corrosion map was already identified in ISO 9223, where the exposure test using steel samples is conducted [ 1 ]. Besides, the adjustment of the classification system has been presented in progress based on ISO 9223 [ 2 ]. However, the characterization of the rust on steels at each site has not been conducted sufficiently.…”
