hroughout the Asia Pacific region there are tens of thousands of bridges and related road and rail infrastructure. The variety of designs and construction material used to build these assets present a wide range of challenges to the people charged with managing and maintaining them. Degradation of bridges is caused by many different factors including corrosion and other stresses from both the environment and heavy vehicles passing over them (ref. Opening photo). In Australia, the yearly cost of asset maintenance is estimated to be approximately $32 billion. Avoidable corrosion damage accounts for $8 billion of this

n tutta la zona Asia-Pacifico ci sono decine di migliaia di ponti, con le relative infrastrutture stradali e ferroviarie. La varietà di progettazione e di materiali utilizzati per costruire queste infrastrutture presenta molte sfide per le persone incaricate della loro gestione e manutenzione. La degradazione dei ponti è causata da molti fattori diversi, inclusa la corrosione e altre sollecitazioni derivanti sia dall’ambiente sia dai mezzi pesanti che li attraversano (rif. foto d’apertura). In Australia il costo annuale per la manutenzione delle infrastrutture è stimato in circa 32 miliardi di dollari. Danni da corrosione evitabili incidono per 8 miliardi di dollari e continuano ad avere un impatto notevole

When we think of corrosion, those who are not acquainted with the theory and practice of metallurgy tend to think that it occurs only in surface weather conditions and on outdoor objects and structures. Insiders, however, know perfectly well that this is not the case: corrosion attacks metal substrates whether they are installed on the earth’s surface or beneath it, buried or submerged. And things become even more complicated if these assets are located on the surface, but offshore. This issue of ipcm_Protective Coatings, which inaugurates our seventh year of publication, presents an unprecedentedly wide variety of articles dealing with research, development, and innovative products engineered to effectively meet the specific needs of an industry.
