Abstract Titanium exhibits poor mechanical features such as low hardness and wear resistance. In this research, we considerably enhance the hardness and wear resistance of Ti by a simple laser surface treatment method. Titanium carbide (TiC) structure was successfully generated on Ti samples by means of laser. Vickers hardness indenter, wear test, impedance spectroscopy, and polarization analyses were carried out to scrutinize the mechanical and corrosion properties of samples. Adhesion between Ti and the formed TiC structure is favorite aspect of this method. The results confirmed that the TiC layer improved the mechanical hardness of the Ti. Additionally, the friction coefficient values of laser-treated Ti samples dramatically decreased. The surface roughness of laser-treated Ti declined to its minimum value with increase in laser-treatment time. Although, laser-surface treatment of Ti did not make an evident change in the corrosion resistance of Ti in Hank's physiological solution compared to reference Ti, the escalation of Ti hardness with laser-treatment time is a favorable aspect of this method.

纯钛的激光表面处理：碳化钛涂层在汉克生理溶液中的显微组织分析、磨损性能和腐蚀行为

摘要 钛具有硬度低、耐磨性差等机械特性。在这项研究中，我们通过简单的激光表面处理方法显着提高了 Ti 的硬度和耐磨性。通过激光在 Ti 样品上成功生成碳化钛 (TiC) 结构。进行维氏硬度压头、磨损试验、阻抗谱和极化分析以仔细检查样品的机械和腐蚀性能。Ti 和形成的 TiC 结构之间的粘附是这种方法最喜欢的方面。结果证实，TiC层提高了Ti的机械硬度。此外，激光处理的钛样品的摩擦系数值显着降低。随着激光处理时间的增加，激光处理钛的表面粗糙度下降到最小值。
