Preparation method of ZrSiO4 anti-oxidation coating on surface of SiC fiber
The invention discloses a preparation method of a ZrSiO4 anti-oxidation coating on a SiC fiber surface. The preparation method comprises the following steps: (1) preparing a ZrSiO4 precursor steeping liquor, reacting and aging; (2) removing glue on the surface of the SiC fiber; (3) carrying out dip-coating on the SiC fiber by using the ZrSiO4 precursor steeping liquor; (4) drying the ZrSiO4 precursor; (5) high-temperature cracking of the ZrSiO4 precursor, the ZrSiO4 coating on the surface of the SiC fiber is prepared through the method, the high-temperature oxidation weight gain rate of the SiC fiber is obviously reduced, and it is indicated that the prepared ZrSiO4 coating can play a remarkable anti-oxidation protection role on the SiC fiber.
本发明公开了一种SiC纤维表面ZrSiO4抗氧化涂层的制备方法，包括(1)ZrSiO4前驱体浸渍液的配制、反应与陈化；(2)SiC纤维表面除胶处理；(3)使用ZrSiO4前驱体浸渍液浸涂SiC纤维；(4)ZrSiO4前驱体干燥；(5)ZrSiO4前驱体高温裂解，本发明通过该方法制备SiC纤维表面的ZrSiO4涂层，明显降低SiC纤维的高温氧化增重率，说明所制备的ZrSiO4涂层可对SiC纤维起到显著的抗氧化保护作用。
