摘要

高熵碳化物具有优异的性能，是在医疗工具上应用保护涂层的理想材料。本研究根据 Ti、Zr、Nb、Ta 和 W 元素的生物相容性和耐腐蚀性，选择它们作为设计空间。机器学习用于优化 TiNbTaZrWC 涂层的成分比例，重点是提高耐磨性。利用脉冲直流磁控溅射技术在 316L 基体表面成功沉积了硬度为 29.31 GPa 的 TiNbTaZrWC 涂层。TiNbTaZrWC 涂层在模拟体液中表现出优异的耐磨性和润滑性。由于其致密的微观结构和优异的耐腐蚀性，TiNbTaZrWC 涂层可防止金属离子从 316L 基质中释放出来，并具有良好的生物相容性。

Enhanced tribo-corrosion resistance of biocompatible TiNbTaZrWC coating through intelligent design strategy

High-entropy carbides have exceptional properties, making them ideal for applying protective coatings on medical tools. This study selected Ti, Zr, Nb, Ta, and W elements as the design space based on their biocompatibility and corrosion resistance. Machine learning was used to optimize the composition ratio of TiNbTaZrWC coating, focusing on improving wear resistance. The TiNbTaZrWC coating with a hardness of 29.31 GPa was successfully deposited on the surface of 316L substrate using pulsed DC magnetron sputtering technology. The TiNbTaZrWC coating exhibited excellent wear resistance and lubricating properties in the simulated body fluid. Due to its dense microstructure and excellent corrosion resistance, the TiNbTaZrWC coating prevented the release of metal ions from the 316L substrate and exhibited good biocompatibility.

期刊介绍： The Chemical Engineering Journal is an international research journal that invites contributions of original and novel fundamental research. It aims to provide an international platform for presenting original fundamental research, interpretative reviews, and discussions on new developments in chemical engineering. The journal welcomes papers that describe novel theory and its practical application, as well as those that demonstrate the transfer of techniques from other disciplines. It also welcomes reports on carefully conducted experimental work that is soundly interpreted. The main focus of the journal is on original and rigorous research results that have broad significance. The Catalysis section within the Chemical Engineering Journal focuses specifically on Experimental and Theoretical studies in the fields of heterogeneous catalysis, molecular catalysis, and biocatalysis. These studies have industrial impact on various sectors such as chemicals, energy, materials, foods, healthcare, and environmental protection.
