Lazer kaplama yöntemi ile kalıp yüzeylerinde
aşınmaya dirençli bir tabaka oluşumu veya kalıpta meydana gelen bölgesel
aşınmaların tamiratı gerçekleştirilebilmektedir. Bu çalışmada, AISI 4140
çeliğinin aşınma direncini geliştirmek amacıyla ferromolibden (FeMo) ve
ferrobor (FeB) takviyeli demir esaslı kaplamalar lazer yöntemi ile
gerçekleştirilmiştir. Kaplamaların aşınma direnci ball-on-disk aşınma testiyle
tespit edilmiştir. Mikroyapı incelemeleri hem optik mikroskop hem de taramalı
elektron mikroskobu altında gerçekleştirilmiştir. Sertlik ölçümü sonucunda FeB
takviyeli kaplamanın FeMo takviyeli kaplamaya göre daha yüksek sertliğe sahip
olduğu görülmüştür. Artan kaplama sertliği aşınma direncini artırarak FeB
takviyeli kaplamada daha az malzeme kaybı meydana getirmiştir.
