Bu çalışmada; FeB FeTi ,FeW ve grafit tozları, kullanılarak düşük karbonlu (%0,15 C) çeliğin yüzeyi, farklı işlem parametrelerinde, Gaz Tungsten Ark Kaynak yöntemiyle (TIG) kaplanmıştır Elde edilen kaplama yüzeyinin mikroyapısı, optik mikroskop (OM) ve taramalı elektron mikroskobunda (SEM) incelenmiştir. Mikrosertlik ve kuru-sürtünme aşınma deneyleri yapılmıştır. Yoğun enerjili X ışını analizi (EDS) ile alaşım elementlerinin yüzeyden altlık malzemesine doğru dağılımı araştırılmıştır. Kaplama bölgesinin mikroyapısında karbür ve borürlerin oluştuğu gözlenmiştir. Elde edilen sert yüzey kaplamalarında oluşan karbür ve borürlerin şekilleri üçgenden düz kareye dönüşmüştür.
