Abstract

In the study, the effects of mechanical alloying duration on corrosion behavior of powder metal aluminum composites reinforced with alumina (Al2O3) were investigated in saltwater medium. For composite materials production, reinforcement Al2O3 powders and base metal aluminum powders were applied one hours mixing or mechanical alloying for 2, 4, 6 and 10 hours. After pressing and sintering treatment of composite powders, electrochemical corrosion tests were applied in saltwater solution (3.5 wt. % NaCl) by potentiodynamic methods. According to corrosion test results, corrosion resistance of composite materials was decreased with increasing of mechanical alloying duration.

Özet

Bu çalışmada toz metalurjisi yöntemi ile üretilen alümina (Al2O3) takviyeli alüminyum esaslı kompozit malzemelerde mekanik alaşımlama süresinin tuzlu ortamdaki korozyon davranışına etkileri incelenmiştir. Numunelerin toz metalurjisi yöntemi ile üretiminde, takviye malzemesi olan Al2O3 tozları ve ana malzeme olan alüminyum tozları karışımına 1 saat karıştırma veya 2, 4, 6, 10 saat mekanik alaşımlama işlemleri uygulanmıştır. Presleme ve sinterleme işlemleri sonrasında elde edilen Al2O3 takviyeli alüminyum esaslı kompozit numunelere tuzlu ortamında (%3,5 NaCl) potansiyodinamik yöntem ile elektrokimyasal korozyon testleri uygulanmıştır. Çalışma sonucunda, mekanik alaşımlama süresinin artması ile Al2O3 takviyeli alüminyum esaslı kompozit malzemenin korozyon dayanımının azaldığı belirlenmiştir.
