Derin Maden Sondajlarında Ön İnceleme Aşaması Mühendislik Yaklaşımları ve Fizibilite Etütlerinin Gerçekleştirilmesi
Öz
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.

The Investigation of Effects of Mechanical Alloying Duration on Corrosion Behavior of Aluminum Composites Reinforced with Al2O3
Öz
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.
