Journal ArticleDOI
Tribological and mechanical behavior of multilayer Cu/SiC + Gr hybrid composites for brake friction material applications
TL;DR: In this paper, the wear surface morphology and mechanisms were studied using scanning electron microscopy (SEM), XRD, and stereoscopy, and the microstructure of the composites was also characterized using SEM and optical microscopy.
Journal ArticleDOI
Effect of SiC volume fraction and size on dry sliding wear of Fe/SiC/graphite hybrid composites for high sliding speed applications
TL;DR: In this article, the friction and wear properties of Fe/SiC/graphite hybrid composites were investigated using a sub-scale dynamometer disk brake testing system, and the effect of coating the SiC particles with BaSO4 was examined.
Journal ArticleDOI
Effect of reinforcement type, size, and volume fraction on the tribological behavior of Fe matrix composites at high sliding speed conditions
TL;DR: In this paper, the tribological behavior of iron matrix composites at high sliding speeds (25 − 35 m/s) typical of aircraft braking conditions was studied using a sub-scale disc braking dynamometer.
Journal ArticleDOI
High-Speed Tribological and Mechanical Properties of Layered Fe/SiC Composites
TL;DR: In this article, the authors studied the high-speed tribological and mechanical properties of layered SiC particulate reinforced iron matrix composites, which consisted of a surface layer with high volume fraction of the reinforcement particles and a layer with low volume fraction in the bulk.
