Bu çalışma saf Al matrise hacimce %40 oranında farklı tane boyutlarına sahip NiAl partikül ilavesinin, üretilen kompozitlerin korozyon performansına etkisini incelemeyi amaçlamaktadır. Takviye malzemesi olarak kullanılan NiAl partiküller ark ergitme yöntemi ile atomca 1:1 oranında üretilip mekanik öğütme yöntemi ile ince partiküller haline getirilmiştir. Sonrasında titreşimli elek ile farklı boyutlarda sınıflandırılarak kompozit üretiminde kullanılmıştır. Böylece partikül boyutunun üretilen kompozitlerin korozif özelliklerine etkisi incelenmiştir. Takviye partikül oranını yüksek tutmak ve homojen dağılım sağlamak için basınçlı infiltrasyon yöntemi ile üretim tercih edilmiştir. Kompozitlerin korozif özellikleri %3,5 NaCl ortamında potansiyodinamik polarizasyon ve daldırma korozyon testi uygulanarak belirlenmiştir. Her iki deney metodunda da tane boyutu düştükçe korozyon dayanımının arttığı gözlenmiştir.

This study aims to investigate the effect of the addition of 40% by volume NiAl particles with different grain sizes to the pure Al matrix on the corrosion performance of the produced composites. NiAl particles used as reinforcement material were produced by arc melting method at a ratio of 1:1 by atom and turned into fine particles by mechanical grinding method. Afterwards, it was classified in different sizes by vibrating sieve and used in composite production. Thus, the effect of particle size on the corrosive properties of the produced composites was investigated. Production with pressure infiltration method was preferred in order to keep the reinforcement particle ratio high and to provide homogeneous distribution. The corrosive properties of the composites were determined by applying potentiodynamic polarization and dip corrosion test in 3.5% NaCl environment. In both test methods, it was observed that the corrosion resistance increased as the grain size decreased.
