- Microscale surface texturing is applicable in many industries. It improves wear resistance, sealing performance, fuel combustion efficiency and osseointegration in a wide range of products.
- The laser shock process is superior to other patterning processes in accuracy, controllability and repeatability.
- Surface texturing through the laser shock process also induces compressive residual stress in the material, improving the hardness, corrosion resistance, fatigue life and wetting performance of the material.
Laser shock process
- When the laser beam impacts on the surface of the ablation layer, high-temperature and high-pressure plasma is generated by ablating a thin portion of the material.
- The plasma generates a pressure wave and forces the workpiece into the mold shape.
Surface texturing
- Microscale patterns with various shapes, sizes and depths have been successfully implemented using the proposed laser shock process
- The surface wettability of the material changes depending on the size and shape of the microscale patterns.
- The required surface properties can be realized by controlling the microscale patterns.
