Ferromolibden ve ferrobor takviyeli lazer kaplamaların aşınma karakteristiği ve mikroyapısı

Öz

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.
