Title:
HIGH ADHESION OXIDATION RESISTANT COATING FILM FOR C/C COMPOSITE MATERIAL AND ITS FORMATION
Document Type and Number:
Japanese Patent JPH08253876
Kind Code:
A
Abstract:
PURPOSE: To provide a high adhesion oxidation resistant coating film layer having excellent oxidation resistance, free from suffering damages such as stripping even if being repeatingly heated and excellent in adhesiveness.
CONSTITUTION: A conversion coating film 3 of silicon carbide 30μm in average film thickness is formed by burying a C/C composite material 2 in an inorganic mixture, obtained by mixing 25wt.% silicon with 75wt.Z silicon carbide in a ball mill for 6hr, to put in a graphite crucible and allowing to react at 1600°C for 280min. After that, a MoSi2 layer 4 is formed with 50μm film thickness on the surface of the conversion coating film 3 by plasma spraying.
