Abstract

In this study, 0,2% and %0,5 carbon added DistaloyAB metal powders were pressed under 420 MPa compression and sintered. The specimens produced were coated with diamond nanoparticle added chromium using electrochemical method. The coated and uncoated specimens were compared and the effect of coating on the microstructure, and corrosion behavior of the powder metal specimens was studied. The specimens were examined with scanning electron microscope (SEM) and atomic force microscopy (AFM). Their corrosion rates were measured in 0,1 M H2SO4 and 0,1M NaOH solutions by applying Tafel extrapolation method. The experimental results showed that coating of powder specimens with diamond nanoparticles added chromium decreases corrosion rate the samples.

Özet

Bu çalışmada; iki farklı kimyasal bileşimdeki DistaloyAB tozlarından üretilen numunelere uygulanan nanoelmas ilaveli krom elektrokaplama işleminin numunelerin mikroyapı ve korozyon davranışına etkisi incelenmiştir. % 0,2 ve % 0,5 karbon ilaveli DistaloyAB tozları 420 MPa basınçta sıkıştırılmış ve sinterlenmiştir. Üretilen numunelerin SEM ve AFM incelemesi ve korozyon testleri yapılmıştır. Numunelerin korozyon hızları 0,1M H2SO4 ve 0,1M NaOH çözeltilerinde, Tafel ekstrapolasyonu yöntemi ile ölçülmüştür. Deneysel sonuçlar, toz metal numunelerin nanoelmas ilaveli krom ile kaplanması ile korozyon hızlarında önemli azalmalar olduğunu göstermiştir.
