Abstract
Fe-SiC composite was prepared by HIP technique. Although iron is easy to react with SiC at high temperature, the reaction was successfully controlled below 6% under the hipping conditions of 800-900°C, 50-200 MPa and 30 min. Furthermore, dense and pore free composites with the compositions of Fe-5 wt%SiC and Fe-25 wt%SiC were obtained at 800 and 900°C, applying 50-200 MPa and 200 MPa, respectively. The reaction layer between Fe and SiC was about 3 μm in thick, according to the EPMA observation of the cross section of the composite. The Fe-SiC composite exhibited an excellent wear resistance, which was improved with hipping pressures.
