Development of Silicon Carbide Coating on Al2O3 Ceramics from Precursor Polymers by Radiation Curing

Abstract:

Article Preview

Production of reinforced surface ceramic material was investigated by radiation curing-oxidation method. The originality of this research is to use along with polycarbosilane (PCS) an admixture of another preceramic polymer, polyvinylsilane (PVS). PCS, PVS or their combination in cyclohexane solution were spin-coated onto Al2O3 plates or deposited onto porous substrate by dipping method. After radiation oxidation step, used to preserve the coat on the substrate, a heat treatment was applied for crosslinking of the polymer. Thickness and quality of silicon carbide (SiC) film were investigated after pyrolysis.
