Preparation method of SiB6 anti-oxidation coating of C/C composite material
A preparation method of a C/C composite material SiB6 anti-oxidation coating comprises the following steps: preparing a C/C-SiC sample through a two-step embedding method, mixing SiB6 with an isopropanol solution and ethanol, adding I2 to prepare a suspension B, placing the suspension B in a reaction kettle, selecting a graphite matrix as an anode of the reaction kettle, and adopting a C/C-SiC matrix as a cathode to carry out pulsed arc discharge deposition to prepare the C/C-SiC-SiB6 sample. According to the pulsed arc discharge deposition method, on the basis of a hydrothermal electrophoretic deposition process, continuous and stable direct-current voltage at the two ends is increased to pulse voltage, the pulse voltage can generate electric arcs between a cathode and an anode, the electric arcs can enable coating particles to be instantly heated and sintered together, and therefore the density and crystallinity of the coating are greatly improved.
一种C/C复合材料SiB6抗氧化涂层的制备方法，通过两步包埋法制备C/C‑SiC试样，将SiB6与异丙醇溶液、乙醇混合后加入I2制备悬浮液B，将悬浮液B放置于反应釜内，反应釜的阳极选用石墨基体，阴极采用C/C‑SiC基体进行脉冲电弧放电沉积制备C/C‑SiC‑SiB6试样。本发明脉冲电弧放电沉积法是在水热电泳沉积工艺的基础上将两端的连续稳定的直流电压提升为脉冲电压，脉冲电压可以在阴、阳两极间产生电弧，电弧可以使涂层颗粒瞬间温度提升并烧结在一起，这大大提高了涂层的致密度和结晶度。
