Bu
çalışmada, alümina (Al₂O₃) takviyeli alüminyum esaslı toz
metal kompozit malzemeler, korozyon dayanımını geliştirmek amacıyla iletken
polimer polipirol (Ppy) ile kaplanmış ve yapılan kaplama işleminin kompozit
malzemenin korozyon davranışına etkileri incelenmiştir. Toz metalürjisi yöntemi
ile üretilen alüminyum esaslı kompozit malzemenin polipirol kaplama işlemi,
elektrokimyasal yöntem ile potansiyel taraması uygulanarak yapılmıştır.
Kaplamasız ve dört farklı sayıda potansiyel taraması yapılarak polipirol
kaplanan alümina takviyeli alüminyum esaslı kompozit numunelere tuzlu ortamında
potansiyodinamik yöntem ile elektrokimyasal korozyon testleri uygulanmıştır.
Çalışma sonucunda,  alümina takviyeli
alüminyum esaslı kompozit malzemenin uygun şartlar altında elektrokimyasal
yöntem kullanılarak polipirol ile kaplanabildiği ve yapılan kaplamanın kompozit
malzemenin korozyon dayanımını geliştirdiği belirlenmiştir.
