Hafif metalik mühendislik malzemelerinden biri olan AZ91 magnezyum alaşımı; sahip olduğu düşük yoğunluk ve yüksek özgül mukavemet özelliklerinden dolayı endüstrinin birçok alanında yapı malzemesi olarak tercih edilmektedir. Ancak AZ91 alaşımının sahip olduğu güçlü yapısal özelliklerine rağmen yüzey özelliklerinin sınırlı olması, saldırgan ortamlarda ve aşırı yük altında düşük dayanıma sahip olmasına dolayısıyla bu alaşımların kullanımlarının sınırlı kalmasına neden olmaktadır. Bu alaşımların zayıf yüzey özelliklerini geliştirmek ve endüstrinin farklı alanlarında kullanımlarını arttırılabilmek için yüzey kaplama işlemleri uygulanabilmektedir. Bu çalışmada; AZ91 magnezyum alaşımının yüzey özelliklerini iyileştirilebilmek amacı ile soğuk sprey (SS) yöntemi ile Al kaplamaların büyütülmesi amaçlanmıştır. Büyütülen kaplamaların yapısal morfolojik analizleri kaplamaların XRD ve SEM analizleri ile sertlik değerleri ise mikro sertlik ölçme yöntemiyle tespit edilmiştir.

Deposition of Al Coatings by Cold Spray Method on AZ91 Mg Alloy

Öz

AZ91 magnesium alloy, one of the lightweight metallic engineering materials; is preferred as a building material in many areas of industry due to its low density and high specific strength properties. However, despite the strong structural properties of the AZ91 alloy, the limited surface properties cause low strength in aggressive environments and under extreme loads, thus limiting the use of these alloys. Surface coating processes can be applied to improve the weak surface properties of these alloys and to increase their use in different areas of industry. In this study; to improve the surface properties of AZ91 magnesium alloy, it is aimed to enlarge Al coatings by cold spray (SS) method. Structural and morphological analyses of the coatings were determined by XRD and SEM, and hardness values were determined by the microhardness measurement method.
