High-temperature-resistant mullite/yttrium silicate/zirconium oxide composite coating and preparation method thereof
The invention provides a high-temperature-resistant mullite/yttrium silicate/zirconium oxide composite coating and a preparation method thereof, and belongs to the technical field of high-temperature-resistant coatings. The high-temperature-resistant mullite/yttrium silicate/zirconium oxide composite coating is obtained by mixing mullite, yttrium silicate, zirconium oxide, a binder and a dispersing agent, coating the mixture on the surface of a matrix by adopting a brush coating, spray coating or dipping process and then carrying out segmented sintering. According to the preparation method, technical means such as brush coating, spray coating and dipping are adopted, a coating with a certain thickness can be prepared on the surface of any complex workpiece, professional equipment is not needed, operation is easy, and production efficiency is high; two-stage heating is adopted for sintering, the technological process is simple, spray granulation and pre-sintering feeding are not needed, preparation can be completed through one-time sintering, the applicability is wide, operation is convenient, the method can be used for preparing large or special-shaped parts, and wide application prospects are achieved.
本发明提供了一种耐高温莫来石/硅酸钇/氧化锆复合涂层及其制备方法，属于耐高温涂层技术领域。本发明将莫来石、硅酸钇、氧化锆、粘结剂和分散剂混合后，采用刷涂、喷涂或浸渍工艺涂覆在基体表面，然后进行分段烧结，得到耐高温莫来石/硅酸钇/氧化锆复合涂层。本发明的制备方法采用刷涂、喷涂以及浸渍等技术手段，可以在任何复杂工件表面制备一定厚度的涂层，无需专业设备，操作简单，生产效率高；本发明采用两段式升温进行烧结，工艺流程简单，不需要喷雾造粒和预烧喂料，一次烧结即可制备完成，适用性广，操作方便，可用于大型或异型件的制备，具有广阔的应用前景。
