Optimization of Cryogenic Treated Nickel-Based Superalloy in Terms of Electro-Erosion Processing Performance

Abstract

In this study, electrical discharge machining (EDM) performance of cryogenic nickel based superalloy was investigated. For this purpose, thermal resistance nickel based super alloying was applied to shallow and deep cryogenic process. The parameters used in the experiments are designed with the Taguchi L9 orthogonal array to reduce the test cost. The obtained results were examined statistically and the effect of surface roughness and material wear loss (MRR) of cryogenic treatment was investigated. The Gray-Taguchi approach is used to determine the ideal processing parameters. The most effective parameters for surface roughness values are A1B1 and A2B1 for MRR. According to ANOVA results, the most effective parameter for the surface roughness was determined as 70.99% of the time on, the material duration was determined as 71.66% for material wear loss. For the maximum wear amount and minimum surface roughness value, it was determined that the ideal factors for the gray relational grade occur in the parameters performed by the first experiment.

Kriyojenik İşlem Görmüş Nikel Esaslı Süper Alaşımın Elektro-Erozyon İşleme Performansı Optimizasyonu

Abstract

Bu çalışmada kriyojenik işlem uygulanmış nikel esaslı süper alaşımın elektro erozyon işleme (EEİ) ile işlenme performansı araştırılmıştır. Bu amaçla ısıl dirençli nikel esaslı süper alaşıma sığ ve derin kriyojenik işlem uygulanmıştır. Deneylerde kullanılan parametreler deney maliyetini azaltmak için Taguchi L₉ ortogonal diziyle tasarlanmış olup elde edilen sonuçlar istatistiksel olarak incelenerek kriyojenik işlemin yüzey pürüzlülüğü ve malzeme aşınma kaybı (MAK) etkisi araştırılmıştır. Her iki çıktı parametresi için en ideal parametrelerin belirlenmesinde ise Gray-Taguchi yaklaşımı kullanılmıştır. Yapılan çalışmanın sonucunda; yanıt tabloları incelendiğinde yüzey pürüzlülük değerleri için en etkili parametrenin malzeme ve vurum süresi için sırası ile A1B1, malzeme aşınma kaybı için ise A2B1 olarak belirlenmiştir. Anova sonuçlarına göre yüzey pürüzlülüğü için en etkili parametrenin %70,99 ile vurum süresi olarak, malzeme aşınma kaybı için ise % 71,66 ile malzeme olarak oluştuğu belirlenmiştir. Maksimum aşınma miktarı ve en düşük yüzey pürüzlülük değeri için gri ilişkisel derecesi hesaplandığında her ikisi için ideal faktörler birinci deney ile gerçekleştirilen parametrelerde oluştuğu tespit edilmiştir.
