Paper Title:
Formation of ZrO2-Al2O3 Coating Layers on SiC Fiber by Dip-Coating Process
  Abstract

The layers of ZrO2-Al2O3 were coated on the surface of SiC fibers (Tyranno SA fiber) by dip-coating process. The citric acid-ethylene glycol solution containing Al and Zr ions was polymerized at 150oC to obtain a polymerized complex precursor. The 2D-woven SiC Tyranno SA fibers were dipped into this precursor few times. Heat treatment for coated fiber was conducted at 800-1200oC for 1 h in air. Thin film of mixed zirconium/aluminum oxides on SiC fibers were successfully elaborated using the sol-gel process. The coated zirconium/aluminum oxides layer of SiC Tyranno SA fiber was about 200-1000 nm. The coated fibers were stable in an oxidizing environment even at high temperatures.
