Abstract
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.
