Abstract

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.

激光粉末床熔合制备纯钛材料的各向异性磨损和摩擦腐蚀性能

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。
