摘要 高温合金薄壁件是航空发动机和涡轮燃机中至关重要的热端零件,由于其材料难加工和复杂的结构,生产过程中面临着诸多潜在风险,包括质量一致性差、热变形难控制和刀具磨损等。这些潜在风险伴随产品设计制造的全生命周期,在产品从试制阶段转向批量生产阶段时,需要进一步加强质量监控。本文结合标准AS13004《过程失效模式和影响分析(PFMEA)和控制计划》,应用PFMEA质量工具,通过结构化方法分析了风险顺序和缺陷根源,并针对高风险环节制定了有针对性的控制计划,将某机加批产线的高温合金薄壁件产品合格率由80%提高到96%。 High-temperature alloy thin-walled components are vital thermal parts in aircraft engines and gas turbines.Due to their materials that are difficult to process and complex structures,there are faces numerous risks during production,including inconsistent quality,thermal deformation that is difficult to control,and tool wear.These risks persist throughout the whole lifecycle of design and production,which means that enhanced quality monitoring is needed in the transition from the stage of prototyping to mass production.This paper combines the standard AS13004,Process Failure Mode and Effects Analysis(PFMEA)and Control Plans.Applying the PFMEA tool,it analyzes risk sequences and root causes of defects through structured method.Devising targeted control plans for high-risk areas,it effectively improves the qualification rate of high-temperature alloy thin-walled components in a machining production line from 80% to 96%.
