Abstract

Bilindiği üzere metalik malzemeler için korozyon hayati hasar türlerinden biridir. Yapılan araştırmalarda korozyonun ülkelere olan maliyetinin gayri safi milli hasılanın (GSMH) %3,5-4’ ü kadar olduğu belirlenmiştir. Bu sebeple üstesinden gelmek için çok çeşitli yöntemlere başvurulmaktadır. Bunlar başlangıçta tasarım yani malzeme-ortam uyumunu temin etmek, inhibitör kullanmak, kaplamalar yapmak ve kullanılacak malzemeyi direnci yüksek elementlerle takviye etmektir. İşte bu aşamada test edilen elementler arasında nadir toprak elementleri de önemli yere sahiptir. Nadir toprak elementleri, bildiğimiz şekliyle modern yaşam için çok önemlidir. Nadir toprak elementlerinin kimyası, bu elementlerin korozyon üzerindeki rolünün anlaşılması ve etkili nadir toprak elementi içeren inhibitörlerin hazırlanması için temeldir. Bu çalışmada nadir toprak elementlerinin (NTE) kimyasal özellikleri anlatılarak korozyon özelliklerine ışık tutulmuştur. Daha sonra çelik malzemelerin korozyon özelliklerini nasıl etkilediği incelenmiştir. Çalışmalardan nadir toprak elementlerinin korozyon direnci üzerinde iyileştirici etkiye sahip olduğu belirlenmiştir. Bu iyileştirici etkinin mekanizmaları yapılan çalışmalarla anlatılmıştır. Bu çalışmanın amacı NTE’ nin giderek artan önemine dikkat çekmektir.

Abstract

As is known, corrosion is one of the vital damage types for metallic materials. In the researches, it has been determined that the cost of corrosion to countries is 3.5-4% of the gross national product. (GNP). For this reason, a wide variety of methods are used to overcome it. These are initially design, to ensure material-environment compatibility, to use inhibitors, to make coatings and to alloy the material to be used with elements with high resistance. Among the elements tested at this stage, the rare earth element also has an important place. As we understand it, rare earth elements are important to modern existence. The chemistry of the rare earth elements is fundamental to understanding their role in corrosion and to preparing effective rare earth element containing inhibitors. In this study, chemical properties of rare earth (REE) elements were explained and their corrosion properties were enlightened. Then, how it affects the corrosion properties of steel materials has been examined. It has been determined from studies that rare earth elements have a improving effect on corrosion resistance. The mechanisms of this helpful effect have been described in studies. The aim of this study is to draw attention to the increasing importance of REE.
