Nikel ve kobalt alaşımları
Nikel ve kobalt alaşımları, özellikleri nikel, kobalt veya bunların birlikte kullanıldığı alaşımlama sistemleriyle geliştirilen metalik malzemelerdir. Korozyona, oksidasyona, aşınmaya ve yüksek sıcaklıklarda mukavemet kaybına karşı yüksek dirençle karakterize edilirler; bu nedenle türbin bileşenleri, kimyasal proses ekipmanları ve diğer zorlu yüksek sıcaklık uygulamaları için uygundurlar.
