研究目的
Investigating the influence of contacting film material on the planishing effect of LY2 aluminum alloy surface with corrugated structures using laser shock wave planishing technique (LSWP).
研究成果
The study concludes that the planishing effect on micro-protrusions improves with the density of the contacting foil decreasing, and the lifting effect on the bottom material enhances with the strength of the contacting foil increasing. A high modulus of elasticity contacting foil also facilitates the bottom material bulging. The experimental results match the FEM simulation well.
研究不足
The study focuses on the influence of contacting foil material on the planishing effect, but other factors such as laser parameters and environmental conditions may also affect the results. The FEM simulation assumes certain conditions that may not fully capture the complexity of real-world applications.
1：Experimental Design and Method Selection:
The study used finite element simulation (FEM) to simulate the dynamic response characteristics of surface micro-features under different physical parameters of contacting foils, followed by experimental verification.
2：Sample Selection and Data Sources:
LY2 aluminum alloy plates with periodic surface structures were used as samples.
3：List of Experimental Equipment and Materials:
An EDGEWAVE PX-70 picosecond laser processing system was utilized to create periodic surface structures. Steel and titanium alloys of four different materials were served as contacting foils.
4：Experimental Procedures and Operational Workflow:
The LSWP experiments were conducted with different contacting foils, and the surface morphology was examined by a DSX500 optical digital microscope.
5：Data Analysis Methods:
The 2D and 3D topography measurements were performed to characterize the topography of sample surface.
