Abstract

In this study, were investigated corrosion behavior in different solutions of 12% B4C reinforced Al 2% graphite matrix composite material produced by mechanical alloying method. The prepared powders were mechanically alloying in the planetary type alloying device. Mechanical alloyed powders were produced green compacts by cold pressed under pressure of 750 MPa in a hydraulic press. The green compacts were sintered at 600 °C for 2 hours. Corrosion tests were carried out in two different solutions (3.5% NaCl and 0.1 M H2SO4) by potentiodynamic polarization method. As a result of corrosion tests, low current density was obtained in NaCl solution compared to H2SO4 solution. In addition, in the electrochemical impedance measurements showed that the Nyquist curve in H2SO4 solution had a lower semicircle diameter and an inductive cycle at low frequencies.

Özet

Bu çalışmada mekanik alaşımlama yöntemi ile üretilen %12 B4C takviyeli Al %2 grafit matrisli kompozit malzemenin farklı çözeltilerdeki korozyon davranışı incelenmiştir. Hazırlanan tozlar planeter tip alaşımlama cihazında mekanik alaşımlanmıştır. Mekanik alaşımlanan tozlar, hidrolik preste 750 MPa basınç altında soğuk preslenerek ham numuneler üretilmiştir. Üretilen ham numuneler 600°C sıcaklıkta 2 saat sinterlenmiştir. Korozyon testleri iki farklı çözeltide (%3,5 NaCl ve 0,1 M H2SO4) potansiyodinamik polarizasyon yöntemi ile yapılmıştır. Korozyon testleri sonucunda, NaCl çözeltisinde H2SO4 çözeltisine göre düşük akım yoğunluğu elde edilmiştir. Ayrıca elektrokimyasal empedans ölçümlerinde H2SO4 çözeltisi içerisinde, Nyquist eğrisinin daha düşük bir yarım daire çapına ve düşük frekanslarda endüktif bir döngüye sahip olduğu görülmüştür.
