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 olanAl2O3tozları 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 edilenAl2O3takviyeli alüminyum esaslı kompozit numunelere tuzlu ortamında (%3,5 NaCl) potansiyodinamik yöntem ile elektrokimyasal korozyon testleri uygulanmıştır. Çalışma sonucunda, mekanik alaşımlama süresinin artması ileAl2O3takviyeli alüminyum esaslı kompozit malzemenin korozyon dayanımının azaldığı belirlenmiştir.

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