AZ31B Magnezyum Alaşımının Bilyalı Parlatma Yöntemi ile Mikrosertlik ve Yüzey Pürüzlülüğünün Araştırılması

Öz

Hafif ve yüksek dayanımlı malzemelerden olan magnezyum alaşımları, yetersiz korozyon direnci ve düşük yüzey kalitesi nedeniyle bazı sınırlamalara sahiptir. Bu sınırlamaların üstesinden gelmek, özellikle yüzey özelliklerini iyileştirmek için, ilerleme hızı, devir, kuvvet ve paso sayısı gibi farklı parametrelerle bilyalı parlatma işlemi uygulanmıştır. Deney sayısını azaltmak için Taguchi yöntemi kullanılmış ve S/N oranlarına göre en iyi parlatma koşulları belirlenmiştir. Yüzey pürüzlülüğü ve sertlik testlerinin sonucunda ilerleme hızı ve kuvvetin yüzey kalitesini iyileştirmede önemli parametreler olduğu bulunmuştur. Düşük ilerleme hızı ve yüksek kuvvet parametreleri seçildiğinde en iyi yüzey pürüzlülüğü değeri elde edilmiştir.

INVESTIGATION OF SURFACE ROUGHNESS AND MICROHARDNESS IN BALL BURNISHING PROCESS OF AZ31B MAGNESIUM ALLOY

Abstract

Magnesium alloys which are lightweight and high strength materials have some limitations due to their insufficient corrosion resistance and low surface quality. To overcome these limitations, especially improving surface properties ball burnishing process was applied to magnesium alloy with different parameters like force, number of passes, feed rate and speed. For reducing number of experiments Taguchi method was used and optimum burnishing condition was determined according to S/N ratios. The results of surface roughness and hardness tests show that feed rate and force was found significant parameters for improving surface quality. When lower feed rate and higher force parameters was choosen best surface roughness value was obtained.
