研究目的
Investigating the effects of infrared laser parameters on the surface morphology and hydrophobic properties of aluminum alloy surfaces to fabricate durable superhydrophobic surfaces.
研究成果
The study successfully constructed a durable superhydrophobic surface on aluminum alloy using infrared laser-textured and chemically modified methods. Optimal processing parameters were identified, and the surface maintained superhydrophobicity after aging, indicating good stability and durability.
研究不足
The study focuses on the effects of laser parameters on surface morphology and hydrophobicity but does not extensively explore the mechanical durability under various environmental conditions beyond aging in air.
1：Experimental Design and Method Selection:
The study used infrared laser irradiation to fabricate superhydrophobic surfaces on Al alloy surfaces, followed by chemical modification with hexadecyltrimethoxysilane to decrease surface energy. Laser processing parameters were varied to find optimal settings.
2：Sample Selection and Data Sources:
Al 6061 alloys were used as substrates, polished and cleaned before laser treatment.
3：List of Experimental Equipment and Materials:
Equipment included an infrared laser marking machine (DL-TG-IRF-30), ultrasonic cleaning machine (KQ-300VDE), scanning electron microscope (SEM, EVOMA10), and contact angle measuring instrument (CA100C).
4：Experimental Procedures and Operational Workflow:
Samples were textured with laser pulses, cleaned, chemically modified, and then characterized for surface morphology and hydrophobicity.
5：Data Analysis Methods:
Surface morphology was characterized using SEM, and hydrophobicity was measured using a contact angle measuring instrument with distilled water droplets.
