摘要

我们开发的磷酸铝涂层氧化铝纤维具有显着改善的拔出性能，可用于增强工作温度高达1200°C的高级无机复合材料。使用连续化学气相沉积(CVD)工艺在氧化铝纤维表面生成磷酸铝层:在850°C至1050°C的炉温下，在电炉加热的管式反应器内，将氧化铝纤维暴露于三氯化磷和氧气的气体混合物中，在纤维表面诱导致密的磷酸铝层。通过将涂层纤维嵌入氧化铝基体中制备了微型复合材料。

Coating of Alumina Fibres With Aluminium Phosphate by a Continuous Chemical Vapour Deposition Process†

We developed aluminium phosphate-coated alumina fibres with significantly improved pull-out properties, which may be suitable for reinforcing advanced inorganic composites qualified for operating temperatures up to 1200 °C. Aluminium phosphate layers are generated on the surface of alumina fibres using a continuous chemical vapour deposition (CVD) process: At furnace temperatures between 850 °C and 1050 °C, within a tube reactor heated by an electrical furnace, the alumina fibres are exposed to gas mixtures of phosphoryl trichloride and oxygen, inducing dense aluminium phosphate layers on the fibre surface. Mini-composites were prepared by embedding the coated fibres into an alumina matrix.

期刊介绍： Chemical Vapor Deposition (CVD) publishes Reviews, Short Communications, and Full Papers on all aspects of chemical vapor deposition and related technologies, along with other articles presenting opinion, news, conference information, and book reviews. All papers are peer-reviewed. The journal provides a unified forum for chemists, physicists, and engineers whose publications on chemical vapor deposition have in the past been spread over journals covering inorganic chemistry, materials chemistry, organometallics, applied physics and semiconductor technology, thin films, and ceramic processing.
