Abstract

This study examined the influence of titanium (Ti) and vanadium (V) doping on the mechanical performance and scratch resistance of diamond-like carbon (DLC) coatings applied to commercially pure titanium (Cp-Ti) substrates. The coatings were produced using physical vapor deposition (PVD), and scratch tests were performed under dry, Ringer’s solution, and lubricated conditions. Structural and mechanical characteristics were assessed via X-ray Diffraction (XRD), X-ray Photoelectron Spectroscopy (XPS), Scanning Electron Microscopy (SEM), and microhardness tests. Surface hardness, residual stress, and coating thickness showed notable changes with Ti and V incorporation compared to untreated Cp-Ti. Scratch resistance varied with environment, with lubricated conditions offering the highest resistance and producing narrower scratches than those in Ringer’s solution. These outcomes were linked to the uniform carbide distribution and increased compressive residual stresses in the doped coatings.

不同摩擦学环境：干燥、生物水和润滑条件下，钛和掺钒类金刚石涂层在商业纯钛上的多道划痕性能

本研究考察了钛（Ti）和钒(V)掺杂对类金刚石（DLC）涂层的力学性能和抗划伤性能的影响，这些涂层应用于商业纯钛（Cp-Ti）基体。涂层采用物理气相沉积（PVD）技术制备，并在干燥、林格溶液和润滑条件下进行划痕测试。通过x射线衍射（XRD）、x射线光电子能谱（XPS）、扫描电子显微镜（SEM）和显微硬度测试评估了结构和力学特性。与未处理的Cp-Ti相比，掺入Ti和V后表面硬度、残余应力和涂层厚度发生了显著变化。抗划痕性随环境而变化，润滑条件下提供最高的阻力，产生比林格氏溶液更窄的划痕。这些结果与掺杂涂层中均匀的碳化物分布和增加的压缩残余应力有关。
