| Summary: | Purpose - The aim of this paper is to study the tribological behaviour of Fe-C-Al cast iron at different temperatures using universal pin-on-disk machine.
Design/methodology/approach - The cold set resin bonded sand mould casting process was employed to develop Fe-C-Al cast iron and Fe-C-Si cast iron. The microstructures of materials were studied using field emission scanning electron microscope. The wear and friction tests were conducted using universal pin-on-disk machine at 25 0C, 100 0C, 200 0C and 300 0C temperature. The wear damage surface was characterized using scanning electron microscopy.
Findings - The lower wear rate was found for Fe-C-Al cast iron compared to Fe-C-Si cast iron and delamination type wear morphology was observed in both types of cast iron materials. The results also showed that the friction coeficient value of Fe-C-Al cast iron was lower than Fe-C-Si cast iron at different temperature. It can be concluded that the overall tribological behaviour of Fe-C-Al cast iron at higher temperature was better than conventional Fe-C-Si cast iron.
Originality/value - The information on the development and tribological properties of the Fe-C-Al cast iron at different temperatures is scare in literature. The special type of cold set resin bonded sand mould was used for casting this Fe-C-Al cast iron material. Therefore, current study is quite new and it is hoped that it will provide a high value to the automotive and other engineering researchers for the application of this material. |
