Method for electrophoretic coating of ceramic matrix composite component with environmental barrier
The invention relates to a method for the electrophoretic production of an environmental barrier coating (12) on a ceramic matrix composite component (10), comprising the following steps: E10: electrophoretic application to a surface (S) of the component (10) of a liquid suspension of a composition comprising at least one rare earth silicate powder and an electrically conductive filler; e20: drying the applied suspension; and-E30: subjecting the rare earth silicate powder to a sintering heat treatment, characterized in that at least one nitrate selected from the group consisting of nitrates of aluminum, yttrium and ytterbium is used as the conductive filler in an amount of between 0.2 and 1 mmol per liter of the liquid suspension.
本发明涉及一种用于在陶瓷基复合材料部件(10)上电泳生产环境屏障涂层(12)的方法，该方法包括以下步骤：‑E10：向部件(10)的表面(S)电泳施加包括至少一种稀土硅酸盐粉末和导电填料的组合物的液体悬浮液；‑E20：干燥所施加的悬浮液；和‑E30：对稀土硅酸盐粉末进行烧结热处理，其特征在于，作为导电填料，使用选自由铝、钇和镱的硝酸盐组成的组中的至少一种硝酸盐，该至少一种硝酸盐的量在每升液体悬浮液0.2至1毫摩尔之间。
