| description | In the centrifugal casting process, the casting temperature parameters affected the microstructure characteristics, and the performance of the materials was greatly significant. ZTA (ZrO _2 reinforced Al _2 O _3 ) particles reinforced HCCI (High chromium cast iron) matrix composites with honeycomb structure were obtained by centrifugal casting. With the increased casting temperature (1450 °C, 1500 °C, 1550 °C, and 1600 °C), the austenite equivalent diameter size was 43.5 μ m, 34.8 μ m, 33.1 μ m, 22.3 μ m respective in the compound area and 58.3 μ m, 63.1 μ m, 65.2 μ m, 71.5 μ m respective in substrate area. The average size of eutectic carbides in the compound area decreased from 5.7 μ m to 2.5 μ m with the casting temperature increased. Meanwhile, the lattice constants of austenite and carbide increased with the increased temperature. The hardness of the composites increased by 4 ∼ 6HRC with a change in casting temperature. The results of three-body abrasive wear under high-stress static load conditions showed that the wear volume loss of the composites reduced with the temperature increased and the wear resistance was 1.4 times at 1600 °C than that at 1450 °C. |
