Abstract

Nickel was infiltrated into the carbon/silicon carbide (C/SiC) composite by liquid impregnation and reduction method. The influence of nickel on the process of chemical vapor infiltration of carbon has been investigated. The catalysis of nickel was studied by weight analysis, the microstructure of the material was observed by SEM and the composition was analyzed by XRD. The results shows that nickel infiltrated into C/SiC composites accelerates the deposition of carbon in the material. The mass gain rate of carbon reached the maximum (9.98%) when nickel content was 4.4%. The carbon deposited is aggregative state consisting of fine particles. During CVI process, nickel reacts with silicon carbide to form Ni₂Si and Ni₃Si.
