This invention discloses a five-layer electrodeposited high-sealing corrugated pipe based on ultrasound assistance and its preparation method, belonging to the technical field of metal corrugated pipe manufacturing. It aims to solve the problem that in multi-layer electrodeposited corrugated pipes, it is difficult to effectively coordinate current density, surface quality, and interfacial bonding strength, leading to insufficient densification of the deposited layer, unstable interlayer bonding, poor wall thickness uniformity, and failure to meet airtightness standards, ultimately resulting in poor overall performance stability. This invention includes a five-layer composite structure in which the pipe wall is composed of alternating nickel-cobalt alloy and copper layers. Each layer of the five-layer composite structure undergoes ultrasonic vibration treatment during deposition. The corrugated pipe prepared by this invention has a uniform and dense deposited layer with good interlayer bonding. The five-layer alternating deposition layer composite structure not only achieves uniform stress transmission and dispersion, effectively delaying crack propagation and interfacial penetration, but also improves the uniformity of wall thickness distribution, enabling the corrugated pipe to exhibit higher structural stability and long-term reliability in a sealed environment.
