Abstract

The AISI 316L steel is a material used to manufacture prostheses and medical instruments due to its high corrosion resistance. However, its wear resistance is low, but it can be improved by synthesizing thin films of titanium nitride (TiN) on the surface. This compound is a hard material that improves its tribological and corrosive properties, in addition to presenting good adhesion to the substrate. In this work, a Ti/TiN thin film was obtained using the Physical Vapor Deposition (PVD) technique. This coating was characterized by scanning electron microscopy, energy dispersion spectroscopy (EDS), and light microscopy; additionally, tribological tests under wet conditions and adhesion tests were conducted. The coating showed good adhesion to the substrate according to the VDI standard. In tribological tests, a low coefficient of friction vs. a polyethylene pin in a wet environment (bovine serum) was obtained. The EDS showed a high concentration of Ti and N on the substrate even after wear tests.

提出了一种可植入生物医学装置中平面电感器的设计算法

AISI 316L钢是一种用于制造假肢和医疗器械的材料，因为它具有很高的耐腐蚀性。但其耐磨性较低，但可以通过在表面合成氮化钛(TiN)薄膜来提高耐磨性。这种化合物是一种硬质材料，除了与基材有良好的附着力外，还能改善其摩擦学和腐蚀性能。本文采用物理气相沉积(PVD)技术制备了Ti/TiN薄膜。采用扫描电子显微镜、能谱仪(EDS)和光镜对涂层进行了表征;此外，还进行了湿条件下的摩擦学测试和附着力测试。涂层与基材的附着力符合VDI标准。在摩擦学试验中，获得了与聚乙烯销在潮湿环境(牛血清)中的低摩擦系数。EDS显示，即使经过磨损测试，基底上仍有高浓度的Ti和N。
