摘 要：<正> The wetting behaviour of titanium carbide by molten nickel was investigated at different oxygen partialpressures by using the sessile drop method.Special attention was paid to the kinetics of wetting.Wettingprocess in the Ni/TiC system is controlled by the dissolution of TiC in the liquid phase.Discussions weremade on the basis of the new experimental results achieved in the present investigation and those given inthe literature for the Ni/TiC system and for some similar metal/carbon systems to elucidate how theinterfacial dissolution reaction influences the wetting process.The reactive wetting process is a complex mat-ter and is very sensitive to the experimental conditions.Implantation of the wetting study in the compositeprocessings was also suggested and the optimum processing is proposed.
