This project aims to develop large scale production techniques to obtain adherent diamond like carbon (DLC) based nanocomposite coatings on biomedical implants by developing an integrated physical and chemical vapor deposition system with sputtering, plasma, and end hall ion sources for improved lifetime and biomedical performance. The key issues to be addressed include introduction of different carbon sources to increase the deposition rates, nanostructures, and new interfacial designs to improve the adhesion of DLC based coatings to the implant substrates. The techniques to be explored include liquid hydrocarbon sources, the newly developed nanointerlayers and nanocoatings, and synchrotron based spectroscopy for characterization.

该项目旨在开发大规模生产技术，通过开发集成的物理和化学气相沉积系统，利用溅射，等离子体和端厅离子源，在生物医学植入物上获得粘附的类金刚石碳（DLC）基纳米复合材料涂层，以提高寿命和生物医学性能。要解决的关键问题包括引入不同的碳源，以提高沉积速率，纳米结构，和新的界面设计，以提高DLC涂层的附着力的植入物基板。待探索的技术包括液态烃源、新开发的纳米夹层和纳米涂层以及用于表征的同步加速器光谱。
