Abstract

The chemical interaction between SiAlON ceramics in three different compositions and four different types of steel and also pure iron as reference, were investigated by means of static interaction couple experiments. The tests were carried out in $10^{-2}$mbar vacuum at 1150°C, under the pressure of 5-7MPa for 15 hours. Interfaces of reacted couples were analysed by optical and scanning electron microscope (SEM) including energy-dispersive X-Ray spectroscopy (EDX). In this study, the effects of alloying elements in steel and starting compositions of SiAlON on the chemical reactivity were investigated by comparing the tendency of diffusivity of SiAlON ceramics according to steel type and discussed in detail by determining the interaction zones.

Özet

Üç farklı kompozisyona sahip SiAlON seramikleri ile saf demir ve dört ayrı tipteki çelik arasında meydana gelen kimyasal etkilesim; statik etkilesim çifti deneyleri yoluyla incelenmistir. Etkilesim çifti deneyleri; $10^{-2}$mbar vakum altında, 1150°C’de 5-7MPa yük kullanılarak 15 saat süreyle gerçeklestirilmistir. Etkilesime giren seramik-metal çiftlerinin ara yüzeyleri optik ve taramalı elektron mikroskobunda (SEM) incelenmis, enerji saçınımlı X-ısını spektrometresi (EDX) ile analiz edilmistir. Bu çalısmada, seramik kompozisyonunun ve alasım elementlerinin kimyasal reaktiviteye etkisi; etkilesim bölgeleri belirlenerek incelenmis, SiAlON seramiklerinin çelik tipine bağlı olarak difüzivite eğilimleri karsılastırılmıs ve sonuçlar ayrıntılı olarak tartısılmıstır.
