项目摘要

The objective of this Grant Opportunity for Academic Liaison with Industry (GOALI) collaborative research project is to investigate the material substrate-processing interfacial conditions in chemical vapor deposition (CVD)-grown diamond films on cobalt-cemented tungsten-carbide (WC-Co) tools. Coating delamination is the major life-limiting factor to diamond-coated WC-Co cutting tools. Interface engineering, by means of surface treatments and interlayer, and optimum nanocrystalline diamond (NCD) deposition are the key solutions to achieve high-quality diamond coatings for dry machining. This collaborative research will focus on the fundamental mechanisms of interface fabrications, properties and functions to enhance the substrate/coating performance over the life of the cutting tools, and will form joint tasks of modeling, characterization, and optimization of surface conditioning, interlayer interfacial preparations, and subsequent deposition processes. Validation of enhancements to interfacial performance will be demonstrated through machining analysis and wear characterization. In addition, environmental process monitoring, in both coating and dry machining with diamond coated tools, will be conducted with data collected for life-cycle inventory and environmental impact analysis.If successful, this research will lead to breakthrough of diamond coated tools whose performance is comparable to or better than costly polycrystalline diamond tools. Engineering of interlayer and NCD coating optimization, with material characterizations and performance analysis, will further mature the diamond coated tooling technology for industrial applications. This research will also advance knowledge of interface science, critical to coating system functions, especially in harsh tribological services. The findings gained on interface characteristics and behavior modeling will also offer knowledge transformable to other coating system studies. The proposed program will also synergize universities-industry partnership by providing opportunities for faculty and students to conduct research and gain experiences with production processes in an industrial setting. The collaborations will offer opportunity to students working with industrial colleagues and use of their state-of-the-art equipment facilities.
这个学术联络与工业(GOALI)合作研究项目的赠款机会的目的是调查在化学气相沉积(CVD)生长的金刚石薄膜的钴硬质合金(WC-Co)工具的材料基板处理界面条件。涂层剥落是影响金刚石涂层WC-Co刀具使用寿命的主要因素。界面工程,通过表面处理和中间层,以及最佳的纳米金刚石(NCD)沉积是获得高质量的金刚石涂层用于干加工的关键解决方案。这项合作研究将侧重于界面制造,性能和功能的基本机制,以提高基体/涂层性能的整个寿命的切削工具,并将形成建模,表征和优化的表面调节,层间界面的准备,和后续的沉积过程的联合任务。将通过机加工分析和磨损表征证明界面性能增强的有效性。此外,还将对金刚石涂层刀具的涂层和干式加工过程进行环境监测,并收集数据进行寿命周期清单和环境影响分析。如果成功,这项研究将导致金刚石涂层刀具的突破,其性能与昂贵的多晶金刚石刀具相当或更好。中间层和NCD涂层优化工程,材料表征和性能分析,将进一步成熟金刚石涂层模具技术的工业应用。这项研究还将推进界面科学的知识,这对涂层系统功能至关重要,特别是在恶劣的摩擦学服务中。在界面特性和行为建模方面的研究成果也将为其他涂层系统的研究提供可转化的知识。拟议的计划还将通过为教师和学生提供在工业环境中进行研究和获得生产过程经验的机会来协同大学与工业的合作伙伴关系。合作将为学生提供与工业同事合作的机会,并使用他们最先进的设备设施。
