Abstract

A high-performance Al₂O₃-PF composite coating was prepared on the surface of polymer matrix composite materials using supersonic high-energy plasma spraying technology. The bonding strength between the composite coating and the matrix was used as the evaluation index. The spraying process parameters were optimized using orthogonal experimental design method. Subsequently, the optimal process was verified based on single factor experimental method, further exploring the influence mechanism of Ar flow rate, spraying current, spraying voltage, and second powder feeding position on the composite coating. Analysis shows that spray voltage, Ar flow rate, and spray current have a significant impact on the experimental results and are the main influencing factors; the second powder feeding position has a relatively small impact on the experimental results and is a secondary influencing factor.

超音速高能等离子体喷涂聚合物基复合材料表面 Al2O3-PF 复合涂层的工艺优化及影响因素

采用超音速高能等离子喷涂技术在聚合物基复合材料表面制备了高性能 Al2O3-PF 复合涂层。以复合涂层与基体之间的结合强度作为评价指标。采用正交实验设计法对喷涂工艺参数进行了优化。随后，基于单因素实验法对优化工艺进行了验证，进一步探讨了氩气流量、喷涂电流、喷涂电压和二次送粉位置对复合涂层的影响机理。分析表明，喷涂电压、氩气流速和喷涂电流对实验结果有显著影响，是主要影响因素；二次送粉位置对实验结果的影响相对较小，是次要影响因素。
