Abstract: Powder metallurgical method was employed for forming sintered Fe-Cu-C materials from elemental powders. These sintered materials were aimed to be employed as base materials for sintered frictional brake pads. In experimental works, powder mixtures were prepared so that the alloy compositions of Fe-6Cu, Fe-6Cu-1C, Fe-6Cu-2C, Fe-6Cu-3C, Fe-6Cu-4C and Fe-6Cu-5C were obtained. The powder mixtures were processed via a normal ‘press and sinter’ method. The graphite contents of up to 4 wt. % caused increased strengths and hardness but decreased ductility. Increase of graphite contents of up to 3 wt. % tended to reduce friction coefficient of the sintered materials. In contrast,the sintered Fe-6Cu-5C material exhibited low strengths but high friction coefficient. Microstructural observation and phase identification of the sintered Fe-6Cu-5C material indicated the presence of the mixtures of Ledeburite, cementite and pearlite.
Description: The Chiang Mai Journal of Science is an international English language peer-reviewed journal which is published in open access electronic format 6 times a year in January, March, May, July, September and November by the Faculty of Science, Chiang Mai University. Manuscripts in most areas of science are welcomed except in areas such as agriculture, engineering and medical science which are outside the scope of the Journal. Currently, we focus on manuscripts in biology, chemistry, physics, materials science and environmental science. Papers in mathematics statistics and computer science are also included but should be of an applied nature rather than purely theoretical. Manuscripts describing experiments on humans or animals are required to provide proof that all experiments have been carried out according to the ethical regulations of the respective institutional and/or governmental authorities and this should be clearly stated in the manuscript itself. The Editor reserves the right to reject manuscripts that fail to do so.
