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.

0218195Bhat该奖项将支持 Deepak G. Bhat 博士和 Ajay P. Malshe 博士拜访委内瑞拉中央大学材料科学与冶金工程系的 Mariana Staia 博士，以计划就基本摩擦学相互作用进行研究合作涂层工具。 虽然人们早已认识到对耐用表面工程工具的需求，但工具与工件之间的配合表面以及接触点处的材料相互作用的摩擦学、化学和物理学尚未完全了解。例如，严格的加工和摩擦条件需要在较宽的温度范围内进行有效润滑，而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，旨在改进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。 美国集团将贡献其在机械加工和加工方面的专业知识，而委内瑞拉方面则拥有摩擦学和冶金测试的设备和专业知识。
