- 摘要:
- 为提升直升机桨叶包片胶接质量，开展激光毛化技术在不同材料包片胶接前表面处理工艺中的有效性研究。分别对经酸洗、喷砂、激光毛化工艺处理后的钛合金、不锈钢、纯镍金属材料试件，进行外观、粗糙度、微观形貌检测，并在胶接后进行浮辊剥离试验、剪切强度试验，结果表明：激光毛化处理可在金属表面获得规则的微观形貌，且试件无变形现象，与喷砂表面同等级粗糙度下，浮辊剥离值及剪切强度明显高于喷砂或酸洗处理的表面，可有效提升胶接结合强度。
- Abstract:
- In order to improve the bonding quality of helicopter slurry pack, the effectiveness of laser texturing technology in surface treatment before bonding was studied. The test panels of titanium alloy, stainless steel and pure nickel treated by acid pickling, sand blasting and laser texturing were tested and verified by appearance, roughness, micro-morphology and dry floating peeling test. The results indicated that the regular micro-morphology can be obtained by laser texturing on the surface of metal, and no deformation in the test panels. Under the same roughness, the value of floating roller peel and shear strength resistance of the test panels treated by laser texturing is higher than that of test panels treated by acid pickling and sand blasting, which shows that the bonding strength can be improved effectively by laser texturing.
