- Abstract
Composites of honeycomb-structured high-chromium cast iron matrix reinforced with zirconia-toughened alumina particles (ZTAP) were successfully fabricated by a non-pressure infiltration casting process. Different preform hole patterns were designed in this study, following the principle of keeping the same area of the honeycomb holes with the same outline size. The hardness and modulus continuously increased from the high-chromium cast iron matrix through the interfacial layer to the ZTA ceramic particle. The residual thermal stress in the samples with the circle hole pattern was the lowest at 389.7 ± 20.2 MPa. The wearing volume loss of the composites with the regular hexagon pattern was minimal after four periods.
