摘      要：Cobalt-silicon based carbon composites(Co–Si/C)have established a noteworthy consideration in recent years as a replacement for conventional materials in the automotive and aerospace *** achieve the composite,a reactive melt infiltration process(RMI)is used,in which a melt impregnates a porous preform by capillary *** method promises a high-volume fraction of reinforcement and can be steered in such a way to get the good“near-netshaped components.A mathematical model is developed using reaction-formed Co–Si alloy/C composite as a prototype system for this *** wetting behavior and contact angle are discussed;surface tension and viscosity are calculated by Wang’s and Egry’s equations,*** radii of 5μm and 10μm are set as a reference on highly oriented pyrolytic *** graphs are plotted using the model,to study some aspects of the infiltration *** highlights the possible connections among the various *** this attempt,the Co–Si(62.5 at.%silicon)alloy’s maximum infiltration at 5μm and 10μm radii are found as 0.05668 m at 125 s and 0.22674 m at 250 s,respectively.
