| 目的 研究激光清洗和离子轰击对GH4099蜂窝夹层结构钎焊性能的影响，优化GH4099蜂窝夹层结构焊前清洗工艺。方法 分别用400#砂纸、不同激光功率(60~200 W)、不同离子轰击时间(1~2 h)对GH4099带材表面进行了砂纸打磨、激光清洗和离子轰击试验，分析了激光清洗和离子轰击对GH4099表面形貌、O元素含量、BNi2钎料润湿性的影响，测试了不同清洗工艺下蜂窝夹层结构钎焊接头的拉伸性能。结果 随激光功率从60 W增加到100 W，GH4099表面O含量逐渐降低，表面粗糙度逐渐增大，钎料润湿面积百分比增加到83.5%，润湿性增加。当激光功率大于100 W时，表面残留网状分布的氧化物，导致钎料润湿性降低。当激光功率进一步增加到200 W时，氧化物网状分布现象减轻，润湿性随之增加，粗糙度也有所降低;随离子轰击时间从1 h增加到2 h时，带材表面氧化皮逐渐去除干净，钎料润湿性随之增加，钎料对离子轰击2 h的表面的润湿面积百分比达到91.2%，与400#砂纸打磨的相当。经离子轰击2 h、1 020 ℃-15 min钎焊获得的夹层结构等效抗拉强度为11.9 MPa。结论 与激光清洗相比，离子轰击可以同时去除蜂窝型面及附近侧壁部分的氧化皮，能更有效地改善钎料对蜂窝基体的润湿性。 |

| Pre-welding cleaning process is of great importance for honeycomb sandwich structure to gain a satisfactory brazed joint. Due to the poor stiffness in plane direction of honeycomb core, the more effective cleaning method for honeycomb is non-contact cleaning, including laser cleaning and ion bombardment cleaning. The work aims to study the effects of laser cleaning and ion bombardment cleaning methods on brazing property of GH4099 honeycomb sandwich structure, and optimize the pre-welding cleaning process of honeycomb sandwich structure. |
