摘要

本研究探讨了激光冲击强化（LSP）对采用电弧增材制造（WAAM）制造的SS316L骨钉生物相容性和耐腐蚀性的影响。腐蚀测试显示了实质性的改进，腐蚀电流密度从32.137 × 10−4 mA/cm²降低到3.50864 × 10−4 mA/cm²，腐蚀速率从3.66754 × 10−2 mm/年降低到0.400415 × 10−2 mm/年。通过接触角测量评估的表面疏水性表明，在最高LSP强度为15.0 GW/cm²时，表面疏水性增加到98.85°，表明表面性能的改善对生物医学应用至关重要。细胞毒性分析和表面形态学分析表明，L929成纤维细胞的存活率、形态和粘附性随着LSP强度的增加而提高。

Elucidating the impact of laser shock peening on the biocompatibility and corrosion behaviour of wire arc additive manufactured SS316L bone staples

This study investigates the impact of Laser Shock Peening (LSP) on the biocompatibility and corrosion resistance of SS316L bone staples built using Wire Arc Additive Manufacturing (WAAM). Corrosion tests reveal substantial improvements, with a decrease in corrosion current density from 32.137 × 10^− 4 mA/cm² to 3.50864 × 10^− 4 mA/cm², a reduction in corrosion rate from 3.66754 × 10^− 2 mm/year to 0.400415 × 10^− 2 mm/year. Surface hydrophobicity evaluated through contact angle measurements, demonstrates an increase to 98.85° at the highest LSP intensity of 15.0 GW/cm², indicating improved surface properties critical for biomedical applications. The cytotoxicity analysis and surface morphology indicate that the survival, morphology, and adherence of L929 fibroblast cells improve with increasing LSP intensity.
