Porous Metal-Fiber Sintered Felt by Multi-Tooth Cutting and Sintering-Morphological Analysis and Mechanisms

摘要

This study provides a series of investigation on the morphological characteristics and related mechanisms of a porous metal-fiber sintered felt (PMFSF). Multi-tooth cutting and high-temperature solid-phase sintering are used to create the PMFSF. Based on both modeling and experimental methods, the results suggest that the produced fiber has rough surface and curled shape due to cutting deformation. The processing parameters and material mechanical property both have significant effects on formation of fiber morphology. Results also reveal that the fibers in a PMFSF is randomly distributed and connected with each other by forming sintering necks. Besides, the influences of sintering parameters are also analyzed in this work.
