摘要

本研究探讨了激光粉末床熔合（LPBF）制备的纯钛在不同建筑取向（0°、30°、45°、60°和90°，分别用试样I-V表示）下的各向异性磨损和摩擦腐蚀行为。干滑动引起犁耕和氧化磨损，而汉克溶液通过腐蚀-磨损协同作用加速塑性变形。较低的施密德因子偏差（均匀变形）提高了耐磨性：试样V（90°），带<；0001比;施密德因子偏差为0.35时，磨损率最低（0.343 × 10−3 mm3·N−1·m−1和0.451 × 10−3 mm3·N−1·m−1）。这些发现为增材制造生物医用钛合金的微结构设计提供了指导。

The anisotropy wear and tribocorrosion performances of pure titanium fabricated by laser powder bed fusion

This study explored the anisotropic wear and tribocorrosion behavior of pure titanium fabricated via laser powder bed fusion (LPBF) with various building orientations (0°, 30°, 45°, 60° and 90°, denoted as samples I-V, respectively). Dry sliding induced ploughing and oxidative wear, while Hank’s solution accelerated plastic deformation via corrosion-wear synergy. Lower Schmid factor deviation (homogeneous deformation) improved wear resistance: Sample V (90°), with < 0001 > -textured slender martensite and Schmid factor deviation 0.35, showed the lowest wear rate (0.343 × 10⁻³ mm³·N⁻¹·m⁻¹ and 0.451 × 10⁻³ mm³·N⁻¹·m⁻¹). These findings guide microstructure design for additive-manufactured biomedical titanium alloys.
