Abstract

In this study, the corrosion behavior of magnesium matrix composites containing TiNi micro-particles of 5-25% by volume was investigated. Corrosion resistance was determined by potentiodynamic polarization (PDS) tests in 3,5% NaCl solution. The corrosion potential and corrosion current density values of the composites were determined by Tafel extrapolation method. Electrochemical evaluations were supported by metallographic investigations before and after corrosion. The results obtained from experimental studies showed that both the corrosion potential and the corrosion current density values increased with the increasing amount of reinforcement. In the morphological investigations made after the corrosion, pitting and filiform corrosion types were observed in all the composite samples.

Özet

Bu çalışmada, hacimce %5-25 oranında TiNi mikro partikül içeren magnezyum matrisli kompozitlerin korozyondavranışları %3,5 NaCl çözeltisi içerisinde potansiyodinamik polarizasyon (PDS) testleri ile belirlenmiştir.Korozyon potansiyeli (Ecor) ve korozyon akım yoğunluğu (ίcorr) değerleri Tafel ekstrapolasyonu yöntemi ilesaptanmıştır. İçyapıdaki değişimler ve elektrokimyasal sonuçlar birbirini desteklemektedir. Kompozitmalzemelerde artan takviye oranı ile birlikte hem korozyon potansiyeli hem de korozyon akım yoğunluğudeğerlerinin artığı gözlenmiştir. Korozyon testlerinden sonra gerçekleştirilen morfolojik incelemelerde yüzeydeçukurcukların yanı sıra kurtçuklar da tespit edilmiştir.
