Abstract

In this study, the PVD method coated cylindrical specimens produced from Ti6Al4V alloy with AlCrN, TiAlN, TiN, TiSiN coatings at different thicknesses. Profilometer tests were applied to determine the surface properties, such as coating thickness and surface roughness of the coated specimens, and microhardness and wear tests were applied to the specimens to determine the mechanical properties. In the profilometer measurements, the coating thicknesses were measured between 1-5 µm and the surface roughness values between 0.4 and 0.8 µm. From the microhardness and wear results, it was determined that thin-coated specimens gave better results than thick-coated specimens. While TiAlN had the best performance in microhardness and wear tests, this coating was followed by TiSiN, TiN and AlCrN coatings, respectively.

PVD Yöntemi ile Kaplanan Ti6Al4V Alaşımlarının Aşınma, Yüzey, Metalurjik ve Mekanik Özelliklerinin İncelenmesi

Abstract

Bu çalışmada, Ti6Al4V alaşımından üretilen numuneler PVD yöntemi ile farklı kalınlıklarda AlCrN, TiAlN, TiN, TiSiN kaplamalarla kaplanmıştır. Kaplanan numunelerin kaplama kalınlığı ve yüzey pürüzlülüğü gibi yüzey özelliklerini belirlemek için profilometre testleri, mekanik özelliklerini belirlemek için ise numunelere mikrosertlik ve aşınma testleri uygulanmıştır. Profilometre ölçümlerinde kaplama kalınlıkları 1-5 µm arasında, yüzey pürüzlülük değerleri ise 0,4 ile 0,8 µm arasında ölçülmüştür. Mikrosertlik ve aşınma sonuçlarından, ince kaplanmış numunelerin kalın kaplanmış numunelere göre daha iyi sonuçlar verdiği, en iyi performansı TiAlN kaplamanın gösterdiği, bu kaplamayı sırasıyla TiSiN, TiN ve AlCrN kaplamaların takip ettiği tespit edilmiştir.
