International Collaboration: Micro- and Nano-scaleTribological Study of Nano-Crystalline Combinatorial Composite Hard/Soft Coatings in Machining Applications

0218195 Bhat该奖项将支持Deepak G. Bhat和Ajay P. Malshe博士访问委内瑞拉中央大学材料科学和冶金工程系的Mariana Staia博士，以计划在涂层工具的基本摩擦学相互作用方面进行研究合作。 虽然人们早就认识到需要耐用的表面工程工具，但在工具和工件之间的配合表面和接触点处材料相互作用的摩擦学，化学和物理学尚未完全理解。例如，严格的加工和摩擦条件需要在宽的温度范围内进行有效润滑，其中涂层本身的稳定性可能会受到损害。此次访问将有助于设计一项研究，旨在改善切削刀具涂层的生产工艺，从而最大限度地减少加工中对冷却剂和润滑剂的需求，并减少对环境的负面影响。 美国集团将贡献他们在机械加工和加工方面的专业知识，而委内瑞拉方面拥有摩擦学和冶金学测试的设备和专业知识。

0218195BhatThis award will support Dr. Deepak G. Bhat and Dr Ajay P. Malshe to visit Dr. Mariana Staia, of the Department of Materials Science and Metallurgical Engineering of the Central University of Venezuela in order to plan a research collaboration on the fundamental tribological interactions of coated tools. While the need for durable surface-engineered tools has long been recognized, the tribology, chemistry, and physics of materials interactions at the mating surfaces and contact points between the tool and work-piece are not fully understood. For instance, stringent machining and frictional conditions require effective lubrication over a wide temperature range, where the stability of the coating may itself be compromised. The visit will help to design a study that aims to improve the process of producing coatings for cutting tools with the potential of minimizing the need for coolants and lubricants in machining and lessening negative impacts on the environment. The US group will contribute their expertise in machining and processing while the Venezuelan side has the equipment and the expertise for tribological and metallurgical tests.
