Korozyondan birincil derecede etkilenen yapı malzemelerinden olan metaller cephe ve çatı kaplamalarında, taşıyıcı sistemde, kapı ve pencere çerçevelerinde, süslemelerde, betonda donatı çeliği olarak vb. sıklıkla kullanılmaktadır. Bu nedenle metal korozyonun mekanizmasının anlaşılması ve nasıl önlenebileceğinin bilinmesi gerekir. Özellikle atmosferik etkilere açık olan yapı kabuğunda bu konunun önemi artmaktadır. Korozyon olayının yavaş gelişimi nedeniyle göz ardı edilen yapı hasarları yapının bulunduğu ortam şartlarına dikkat edilerek henüz tasarım aşamasındayken uygun malzeme seçimi ve doğru detay tasarımı yapılarak önlenebilir. Özellikle betonarme sistemlerde bazı durumlarda korozyonun oluşması önlemiş olsa dahi gerekli bakım ve onarım yapılmadığında uzun dönemde korozyonun kaçınılmaz olacağı açıktır. Bu çalışmada korozyon mekanizması ve korozyon türleri detaylı olarak anlatılmış ve son bölümde korozyondan korunma yöntemlerinden bahsedilmiştir.
Metals, primarily affected building materials by corrosion, are frequently used in façade and roof coverings, structural system, ornaments, door and window frames, as reinforcing steel in concrete and etc. Therefore, it is critical to prevent corrosion and to understand its mechanism. Moreover, corrosion prove important especially for the building envelope because it is susceptible to atmospheric conditions which lead to building material damages in time. Since corrosion develops slowly, its effects on building materials are usually ignored. However, it can be prevented during the architectural design phase by choosing and applying appropriate materials and detail designs while taking into account environmental conditions. Also, studies show that corrosion can cause devastating damage to metals, and it is inevitable in the long term especially for reinforced concrete systems if periodic maintenance and repair are not carried out. In this study, corrosion mechanism and corrosion types are explained in detail, and lastly, protection methods against corrosion are discussed.
