Description
すなわち、本発明は、
(a)炭素/炭素複合材料上にSiを塗布する工程、及び
(b)塗布されたSiを熱処理して、前記複合材料にSiを含浸させることにより、SiC層とSi
層を順次形成する工程
を含む炭素/炭素複合材料の耐酸化コーティング方法を提供する。
炭素/炭素複合材料(アクロス社のAC150及びAC200)に使用する塗布液として平均60メッシュの直径を有するSi粒子20gをエタノール200mlに混合した溶液を用意した。この混合液をスプレーガンに装入して、上記複合材料の表面に均一に塗布した。塗布終了の後、24時間常温で乾燥し、エタノールを揮発させた。
平均325メッシュの直径を有するSi粉末を塗布したことを除いては製造例1と同一の条件下で2層コーティング層を得た(コーティング層の厚さ: 50μm)。
Siが表面に塗布された複合材料を1600℃に加熱したことを除いては製造例1と同一の条件下で2層コーティング層を得た(コーティング層の厚さ: 40μm)。
Siが表面に塗布された複合材料を1600℃に加熱したことを除いては製造例2と同一の条件下で2層コーティング層を得た(コーティング層の厚さ: 40μm)。
Si粒子10gを使用する以外は製造例1と同一の条件下でコーティング層を得た。次いで、400℃で3時間熱処理し、Si層の上にSiO2酸化層を形成させた(コーティング層の厚さ: 200μm)。
平均325メッシュの直径を有するSi粉末を塗布したこを除いては製造例5と同一の条件下で3層コーティング層を得た(コーティング層の厚さ: 200μm)。
Siが表面に塗布された複合材料を1600℃に加熱したことを除いては製造例5と同一の条件下で3層コーティング層を得た(コーティング層の厚さ: 150μm)。
Siが表面に塗布された複合材料を1600℃に加熱したことを除いては製造例6と同一の条件下で3層コーティング層を得た(コーティング層の厚さ: 150μm)。
800℃で1時間熱処理を施してSi層上にSiO2酸化層を形成したことを除いては製造例5と同一の条件下で3層コーティング層を得た(コーティング層の厚さ: 200μm)(図2)。
平均325メッシュの直径を有するSi粉末を塗布したことを除いては製造例9と同一の条件下で3層コーティング層を形成した(コーティング層の厚さ: 200μm)。
Siが表面に塗布された複合材料を1600℃に加熱したことを除いては製造例9と同一の条件下で3層コーティング層を得た(コーティング層の厚さ: 180μm)。
<製造例12> 3層コーティング層の作製
Siが表面に塗布された複合材料を1600℃に加熱したことを除いては製造例10と同一の条件下で3層コーティング層を得た(コーティング層の厚さ: 180μm)。
コーティング処理されていない炭素/炭素複合材料(対照区)と前記本発明の製造例9によって得られた複合材料を対象にして700℃で酸化実験を行った。その結果、重量損失が対照区においては84%であったが、本発明においては2.2%で約40倍も改善されていることが確認された。
