Fabrication of stainless-steel-fiber-reinforced cordierite-matrix composites of tubular shape using electrophoretic deposition

Stainless-steel (316L) fiber mats shaped into tubular geometry were used to reinforce cordierite. The cordierite-matrix composites were manufactured using electrophoretic deposition and pressureless sintering. The sintered composites, which had an internal and external deposit thickness of similar to1 mm, were free of surface cracks when a deposition time of 2.5 min was used. Metal-fiber-reinforced cordierite composites such as those developed here may constitute a promising alternative for manufacturing damage-tolerant tubular components for applications at temperatures up to similar to900degreesC.
