Ark-Sprey Yöntemi ile Düşük Karbonlu Çelik Üzerine Kaplanan İnconel-625 Alaşımının Sertlik ve Mikro Yapı İncelemesi

Öz

Bu çalışmada endüstriyel uygulamalarda sıklıkla kullanılan SA210 kalite bir düşük karbonlu bir çelik alaşımının yüzey kaplama süreci incelenmiştir. Kaplama yöntemi olarak hava basınçlı ark-sprey yöntemi kullanılmıştır. Kaplama malzemesi olarak ise yüksek Ni içeren Inconel 625 alaşımı uygulanmıştır. Kaplama sırasında kumlama yapılmış bir alt yüzey ve 8 bar hava basıncı kullanılmıştır. Uygulama sonrasında numunelerde taramalı elektron mikroskobu (SEM) ile yan yüzeyden kaplanma durumu incelenmiştir. Ayrıca ana alt malzeme ve kaplama sertliği mikro sertlik yöntemi ile ölçülendirilmiştir. Sonuç olarak kaplama-malzeme ara yüzeyinde bağlanma durumları izlenmiştir. Sertlik ise yaklaşık 1,7 kat kadar artış göstermiştir. Böylece düşük karbonlu bir çeliğin yüzey kaplaması ile geliştirilebilirliği temel olarak incelenmiştir.

Cladding on Low Carbon Steel by Arc-Spray Method Hardness and Microstructure Analysis in Inconel-625 Structure

Öz

In this study, the surface coating process of a low-carbon steel alloy of SA210 quality, which is frequently used in industrial applications, was investigated. The Air pressure arc-spray method was used as the coating method. High Ni-containing Inconel 625 alloy was used as the coating material. A sandblasted substrate and 8 bar air pressure were used during the coating. After the application, the side surface coating of the samples was examined by scanning electron microscope (SEM). In addition, the main substrate and coating hardness was measured by the microhardness method. As a result, the bonding conditions were observed at the coating-material interface. The hardness increased approximately 1.7 times. Thus, the developability of low-carbon steel by surface coating was basically investigated.
