    Solid particle erosion behavior of SiMo ductile cast iron
    (Bayburt University, 2018) Çelik, Gülşah Aktaş; Polat, Şeyda; Atapek, Şaban Hakan; Fidan, Sinan
    SiMo ductile cast iron has been developed to be used at high temperatures as exhaust manifold material. Si and Mo contents in its chemical composition provide high temperature oxidation resistance and high temperature strength. During service, hot corrosive exhaust gas flows through the exhaust manifold and may cause erosion of the manifold surfaces. Thus, in this study, it was aimed to evaluate the performance of SiMo cast iron under severe solid particle erosion conditions, against aluminum oxide particles at 30°, 45°, 60° and 90° impingement angles. Surface degradation of tested alloys were characterized using scanning electron microscope. It was observed that erosion rate increased with increasing impingement angle up to 45°, then decreased as the angle increased, since the mechanism of material removal changed. While ploughing occurred at lower angles, work hardening took place on the worn surface at higher angles.
