    摘要:

    報(bào)道1種制備C/C復(fù)合材料抗燒蝕TaC涂層的新技術(shù)。用紅外光譜、XRD及SEM分析和表征醇基鉭膜,用XRD和SEM分析和表征TaC涂層。制備出的醇基鉭是非晶態(tài)結(jié)構(gòu),在C/C復(fù)合材料上將這種凝膠鋪展形成致密的多層膜。在石墨化爐中多層膜被轉(zhuǎn)化為TaC涂層。在1200℃時(shí),形成的涂層中含有TaC和Ta2O5。高于1400℃時(shí)涂層中只有TaC存在。1600℃時(shí)所形成的涂層是1種連續(xù)致密的層狀結(jié)構(gòu),1400℃時(shí)所形成的涂層是1種多微孔的網(wǎng)狀結(jié)構(gòu)。

    Abstract:

    A new technology for preparation of TaC coating on C/C composite material is reported. The ethylate tantalum film is characterized by FT-IR spectra, XRD and SEM, and the TaC coating is characterized by XRD and SEM. The amorphous ethylate tantalum jellied is prepared and is spreaded out densely on the surface of C/C composite material to form a multi-films. In the graphite furnace the multi-films is transformed into the TaC coatings at various temperatures. At 1 200C the coating contains TaC and Ta2O5,and at above 1 400C only TaC exists. The structure of the coating at 1 600C is a continuous dense stratum structure, and at 1 400C is a porous net structure.
