Abstract
Bu çalışmada atomik % 8 Si içeren Fe-Si ikili alaşımı ile saf demir 900°C, 1000°C ve 1100°C’de 3 saat süre ile Ekabor II tozu ile katı ortamda borlanmıştır. Oluşan borür tabakaların mikroyapısı, faz içeriği, mikrosertlik ve kimyasal kompozisyonu, X-Işınları kırınımı, SEM-EDS ve Vickers Mikrosertlik ölçümü ile karakterize edilmiştir. Her iki malzeme yüzeyinde oluşan borür tabakalarının taraklı bir morfolojide olduğu gözlenmiştir.
Ancak borlama sıcaklığı ve özellikle altlıktaki Si ilavesiyle taraklı yapı kabalaşmıştır. Silisyum bor tabakası içerisinde çözünmemiş ve borür tabakası ile altlık malzeme arasında birikerek geçiş bölgesi olarak tanımlanan bölgeyi oluşturmuştur. Bu bölgenin sertlik değeri yaklaşık 500 HV ölçülmüştür. Her iki altlık üzerinde oluşan borür tabakasının sertlik değeri ortalama 2200 HV’dir. Borür tabakasının kalınlığı her iki malzemede artan borlama sıcaklığıyla birlikte doğrusala yakın bir şekilde artmıştır. Altlıkta bulunan silisyum borür tabaka kalınlığını saf demire göre azaltmıştır. Saf demir ile karşılaştırıldığında Fe-8Si altlık yüzeyinde oluşan borca zengin FeB fazı, Fe2B fazına göre daha fazla oluşmuştur.
