Fabrication of Oxide Ceramics Composite by Reactive Infiltration Process

Abstract:

Reactive infiltration is a manufacturing process of metal matrix composites with low cost and low environmental impacts. In this study, reactive infiltration of a NiO/Ti blended powder preform with molten Al was examined. Titanium powder as an infiltration aid was mixed with NiO powder by various blending ratios. The preform and the Al ingot were then heated together up to 1273K ~1673K and held at these processing temperatures for 60 minutes by an induction furnace in N2 gas atmosphere. After the heating process, the vertical cross section was observed to see whether the infiltration and the in situ reaction occurred successfully. Spontaneous infiltration of molten aluminum into the powder preform did not occur when either processing temperature or blending ratio of titanium was not sufficiently high enough. Spontaneous infiltration occurred when processing temperature and volume fraction of titanium were 1273K, 1373K and 15%, 20%. But when volume fraction of titanium was 25%, the preform exploded by an extremely high. It was confirmed that Al3Ti, Al3Ni2 and Al2O3 were formed after the infiltration.
