AISI T15 Çeliğinin İşlenmesinde PVD TiAlN + Al203 ve CVD TiCN+TiN Kaplama Performansının Araştırılması
Bu çalışmada, 45 HRC sertliğinde aşınma dayanımı yüksek olan AISI T15 yüksek hız çeliği, PVD yöntemiyle TiAlN+Al203 ve CVD yöntemiyle TiCN+TiN kaplanmış karbür kesici takımlarla tornalanmıştır. Kesme derinliğinin (1,5 mm) sabit tutulduğu deneyler, dört farklı kesme hızı (60, 80, 140 ve 200 m/dak) ile üç farklı ilerleme miktarı (0,1, 0,3 ve 0,6 mm/dev) kombinasyonlarında gerçekleştirilmiştir. Çalışmada kesme parametreleri ve kaplama türünün yüzey pürüzlülüğüne etkisi araştırılmıştır. Düşük ilerleme miktarında (0,1mm/dev) PVD TiAlN+Al203 kaplamalı kesici takımlar CVD TiCN+TiN kaplamalı kesici takımlardan daha iyi performans sergilemiştir. Fakat ilerleme miktarının 0,6 mm/dev olduğunda, CVD TiCN+TiN kaplamalı kesici takımlar PVD TiAlN+Al203 kaplamalı kesici takımlardan daha iyi performans sergilemişlerdir. Bu durumun kesici takımların kaplama malzemesinin özelliklerine yorumlanmıştır.
Investigation of PVD TiAlN+Al203 and CVD TiCN+TiN Coating Performance in AISI T15 Steel Processing
In this study, AISI T15 high speed steel with high abrasion resistance of 45 HRC was turned into TiCN+TiN coated carbide cutting tools with TiAlN+Al203 and CVD method by PVD method. Experiments that kept constant the cutting depth (1.5 mm) was conducted combination of four different cutting speeds (60, 80, 140 and 200 m / min) and three different feed rates (0.1, 0.3 and 0.6 mm / rev). In this study, the effect of cutting parameters and coating type on surface roughness was investigated. PVD TiAlN+Al203 coated cutting tools were performed better than CVD TiCN+TiN coated cutting tools in low feed rate (0.1mm / rev). But, when the amount of progression was 0.6 mm / rev, CVD TiCN+TiN coated cutting tools were performed better than PVD TiAlN+Al203 coated cutting tools coated cutting tools in low feed rate (0.1mm / rev). This situation is interpreted to the properties of the coating material of the cutting tools.
