Abstract

Talaşlı
imalat sürecinde kullanılan karbür esaslı kesici takım malzemelerinin takım
ömrünü arttırmada kesme yüzeyinde fiziksel ve kimyasal buhar biriktirme (sırasıyla
PVD ve CVD) gibi yöntemler ile sert seramik kaplamaların uygulanması oldukça
yaygındır. Bu çalışmada, PVD yöntemi kullanılarak, WC/(Ta+W) malzemesi ile
kaplanmış SiAlON seramik matkap uçlarında kaplamanın yapısı, bağlanma
mukavemeti ve performansa etkileri araştırılmıştır. Sonuçlar, kaplama tabakası
WC/(Ta+W) ile SiAlON altlık ara yüzeyindeki bağlanma mukavemetinin yetersiz olduğunu
göstermiş, bu nedenle de kaplamanın takımların kesme performansına herhangi bir
etkide bulunmadığı belirlenmiştir.

The Perfomance of WC-/(Ta+C) Multilayer Coated SiAlON Drilling Tools on Drilling Operation of Carbon Fiber Reinforced Polymer (CFRP) Composites

Abstract

The application of hard ceramic coatings on cutting edges by physical and chemical vapor deposition (PVD
and CVD, respectively) is a widely used technique to improve the life of the carbide based cutting tools in machining
operations. In this study, structure, quality and effects on the cutting performance of WC/(Ta+W) coating layer on a
SiAlON based drilling tool was investigated. The results showed that the bonding between coating layer WC/(Ta+W)
and SiAlON substrate was insufficient and no improvement on the tool life was recorded by the application of coating
on SiAlON drilling tools.
