Use of the Sessile Drop Method to Understand the Behaviour of Self Healing Ceramic Matrix Composite

Abstract:

Article Preview

Surface and interfacial properties of borosilicate glass/ceramic systems have been investigated using the sessile drop method. The purpose is to compare and understand the reactivity of the sealing glass in C / SiC and SiC / SiC composites. A hot wall reactor has been designed to measure the variation of the contact angle and the spreading kinetic according to the temperature (500 to 1100°C) and the atmosphere (Ar, Ar + O2 and Ar + H2O). Chemical and morphological analyses underline (i) the strong reactivity between the liquid and the ceramic, (ii) the influence of the infiltration process and (iii) the strong influence of the oxidizing agent on the wetting behaviour of the glass/ceramic systems.
