Abstract

Apply the centrifugal casting process to the preparation of hypereutectic Al-18% Si alloy cylinder liners. In-situ gradient composites of Al-18wt.%Si Alloy, which possess the microstructures of accumulated primary Si from outer layer to inner layer, have been acquired by changing the rotation rate of centrifugal casting. The distribution of primary Si, the microstructure and hardness of the material were investigated. It was found that with the increase of centrifugal rotation rate, the primary Si of the outer layer is gradually shifted to the inner layer. And the rate is greater, the primary Si refinement effect is better. Meanwhile, the hardness of the material increased with the increase of the number of the primary Si.
