چکیده مقاله
This study investigates the tribological and mechanical performance of copper free brake pad formulations using powder metallurgy and positive molding techniques Six sample types were developed, five of which incorporated varying ratios of micaceous iron oxide MIO and steel fibers M0S15 to M12S3 , while one reference sample C9B6 contained copper and brass chips The goal was to replace copper based components with environmentally safer alternatives without compromising performance Raw materials were homogenized using a ball mill and compacted under controlled pressure and temperature, followed by a multi stage curing process Characterization included SEM/EDXS imaging, porosity measurement via the Archimedes method, hardness testing using Rockwell S scale, and shear strength evaluation according to ISIRI 2798 Results showed that increasing MIO content and reducing steel fibers led to lower porosity from 7 1% to 5 8% and higher hardness from 74 to 80 MIO’s fine, plate like morphology enhanced particle packing and surface coverage, improving mechanical integrity Comparisons between copper free M9S6 and copper containing C9B6 samples revealed superior wettability and hardness in M9S6 due to higher surface energy and Mohs hardness of MIO and steel fibers Shear strength tests confirmed adequate bonding between the friction material and steel backing plate at both room and elevated temperatures Overall, the findings support MIO and steel fibers as effective, eco friendly substitutes for copper in brake pad formulations
