| Research Abstract |
Cast iron has good wear resistance and corrosion resistance. However, higher performances are recently required along with the improvement of the machine performance. In this study, preform of SiC particles, which have high hardness and heat resistance, is fabricated and then is infiltrated with the cast iron melt to obtain the particle-dispersed cast iron composite with superior mechanical properties, wear resistance and recycle properties. In 2004, fabrication conditions which the infiltration is accomplished was investigated. In 2005, the wear properties of the composites were investigated. In 2006, the recycle properties were investigated and the results obtained were concluded.
The SiC particle-dispersed cast iron composite could be fabricated by the melt infiltration into the SiC particle preform in the sand mold. The dispersion of SiC particles leads to the improvement of the wear properties of the cast iron. Reheating experiment of the SiC particle-dispersed composite revealed that the SiC particles exist without melting or decomposition even at the temperature at which the cast iron matrix totally melt. This indicates that the SiC particles in the composite can be rejected from the melt in the melting process and it is easy to recycle the composites.
From these results, it was found that the cast iron composite with superior wear resistance and recycle properties could be fabricated by the infiltration in the sand mold.
