Abstract

Historical bells are worn and damaged by the ravages of time. The repair and restoration of these heritage masterpieces could be attempted using cold technology, provided a sufficient adhesion is reached. In this paper, the improvement of Cu20Sn bell metal repair adhesion by various substrate surface treatments was studied: grinding, polishing, cold spray grit-blasting, and laser texturing using five different patterns. The adhesion was tested by a new, simple glue-less method tailored for testing thick cold spray deposits. It was shown that while the cold spray grit-blasting provides a good adhesion of around 70 MPa, even better results of approximately 120 MPa could be obtained by the laser patterning. The detailed three-dimensional fractographic analysis allowed us to describe the failure mechanism of all specimens. For the best-performing laser texturing, this was a combination of interfacial debonding at the original substrate surface and the deposit cohesive fracture inside the pattern recessed areas.

冷喷涂钟形金属：基材激光表面变形提高附着力

历史的钟被时间的蹂躏磨损和损坏。这些遗产杰作的修复和修复可以尝试使用冷技术，只要达到足够的附着力。研究了磨削、抛光、冷喷砂和激光织构等5种基体表面处理方式对Cu20Sn钟形金属修复附着力的改善。通过一种新的、简单的、专为测试厚冷喷涂沉积物而设计的无胶方法来测试附着力。结果表明，冷喷砂能获得70mpa左右的良好附着力，而激光制模能获得120mpa左右的附着力。详细的三维断口分析使我们能够描述所有试样的破坏机制。对于性能最好的激光纹理，这是原始基底表面的界面剥离和图案凹陷区域内沉积内聚断裂的结合。
