Investigation of Coatability of Mechanically Alloyed AlCuCrFeNi High Entropy Alloy by Physical Vapor Deposition Technique

Abstract

High entropy alloys have been proposed as an alternative to superalloys due to having unique properties. As high entropy alloys continue to be researched, their importance is increasing with their unique and superior properties that can be used in wide areas. In this study, AlCuCrFeNi powders were synthesized by mechanical alloying technique. FCC (Face Centered Cubic), BCC (Body Centered Cubic) and B2 phases were detected in the synthesized powders. After the powders were pelleted, they were deposited on the Monel 400 substrate by the physical vapor deposition (PVD) technique. In this research, the microstructural properties of the produced coating were investigated. After production, an almost homogeneous thin film layer was produced.

Mekanik Alaşımlanmış AlCuCrFeNi Yüksek Entropili Alaşımının Fiziksel Buhar Biriktirme Tekniği İle Kaplanabilirliğinin İncelenmesi

Abstract

Yüksek entropili alaşımlar sahip oldukları üstün özellikleri sayesinde süper alaşımlara alternatif olarak önerilmektedir. Yüksek entropili alaşımlar araştırılmaya devam ettikçe ortaya çıkan özgün ve üstün özellikleri sayesinde geniş alanlarda kullanılabilir olmasıyla birlikte önemi gittikçe artmaktadır. Bu çalışmada mekanik alaşımlama tekniği ile AlCuCrFeNi tozları sentezlenmiştir. Sentezlenen tozlarda YMK (Yüzey Merkezli Kübik), HMK (Hacim Merkezli Kübik) ve B2 fazları tespit edilmiştir. Tozlar peletlendikten sonra fiziksel buhar biriktirme (FBB) tekniği ile Monel 400 altlık malzeme üzerine biriktirilmiştir. Üretilen kaplamanın mikroyapısal özellikleri incelenmiştir. Üretim sonrası homojene yakın bir ince film tabakası üretilmiştir.
