一种等离子喷涂用含BaCrO4耐磨自润滑复合粉末及其制备方法与应用
本发明公开了一种等离子喷涂用含BaCrO4耐磨自润滑复合粉末及其制备方法与应用。本发明的耐磨自润滑复合粉末包括以下重量百分比的组分：耐磨相85‑95％和润滑相5‑15％；所述耐磨相为Al2O3、Cr2O3或ZrO2，所述润滑相为BaCrO4。所述耐磨自润滑复合粉末是通过筛分、机械混合获得，可应用在刷式封严转子跑道涂层中。所述刷式封严转子跑道涂层是采用等离子喷涂方法在转子跑道表面制备包含NiAl、NiCr或MCrAlY(M为Ni或Co)中间层和含BaCrO4耐磨自润滑面层双层结构的涂层。本发明所涉及的复合粉末及涂层的制备方法，成本低，简单易操作，有利于获得组织均匀以及性能良好的刷式封严跑道涂层。
The invention discloses BaCrO4-containing wear-resistant self-lubricating composite powder for plasma spray coating as well as a preparation method and application of the BaCrO4-containing wear-resistant self-lubricating composite powder. The wear-resistant self-lubricating composite powder comprises the following components in percentage by weight: 85-95% of a wear-resistant phase and 5-15% of a lubricating phase, wherein the wear-resistant phase is Al2O3, Cr2O3 or ZrO2, and the lubricating phase is BaCrO4. The wear-resistant self-lubricating composite powder is obtained through screening and mechanical mixing, and can be applied to a brush type sealing rotor runway coating. The brush type sealing rotor runway coating is a double-layer coating which is prepared on the surface of a rotor runway by adopting a plasma spray coating method and comprises a NiAl, NiCr or MCrAlY (M is Ni or Co) intermediate layer and a BaCrO4-containing wear-resistant self-lubricating surface layer. The preparation method of the composite powder and the coating is low in cost, simple and easy to operate, and beneficial to obtaining the brush type sealing runway coating with uniform tissue and good performance.
