İnce Katman Aktivasyon Yöntemi, sanayide aşınma, korozyon ve erozyon hızlarının ölçülmesinde kullanılan en hassas ve güçlü yöntemdir. Yöntemde öncelikle araştırılmak istenen yüzeyde bir radyoaktif katman oluşturulur ve daha sonra burada oluşan aktivite ölçülerek yüzeydeki aşınma incelenir. Aktivitedeki değişimin katman kalınlığındaki azalma miktarına dönüştürülmesi için deneysel yada teorik bir kalibrasyon eğrisine ihtiyaç vardır. Teorik kalibrasyon eğrisi için ilgili maddenin durdurma gücü ve meydana gelen nükleer reaksiyonun tesir kesti enerjiye bağlı olarak çok hassas olarak bilinmelidir. Bu çalışmada havacılık, uzay ve sağlık endüstrisinde yaygın olarak kullanılan Titanyum ve alaşımlarının korozyonunu ve aşınmasını incelemek için, 48Ti(α,n)51Cr reaksiyonun tesir kesiti, farklı optik model potansiyelleri ve düzey yoğunluğu modelleri ile hesaplanmış ve literatürde bulunan deneysel sonuçlarla karşılaştırılmıştır.
