外文摘要：This study develops a dense and adherent micro-arc oxidation (MAO) coating on Ti-6Al-4V alloy (TC4) by integrating picosecond laser texturing with HDTMS-modified nano-Si?N?. The laser texturing pretreatment introduced additional mechanical anchoring sites for the subsequent MAO process, significantly enhancing interfacial adhesion between the coating and the substrate. The textured architecture facilitated retention of wear debris, contributing to improved lubrication during sliding contact. Incorporation of HDTMS-modified nano-Si?N? further increased the coating's microhardness and surface roughness, thereby enhancing its mechanical and tribological performance. Additionally, this dense and adherent ceramic coating effectively impeded the penetration of corrosive ions, resulting in reduced self-corrosion current, improved polarization resistance, and superior corrosion protection. Following surface grafting with –CH?-terminated C16 alkyl chains, the composite coating transitioned from hydrophilic to superhydrophobic, demonstrating notable self-cleaning capability. This work offers a viable strategy to enhance the tribological durability and corrosion resistance of titanium alloys intended for service in harsh marine environments. ? 2026 Elsevier Ltd.
