This SBIR Phase I project is aimed at developing smooth diamond-coated cutting tools, using a novel deposition technology that provides an ultra-nanocrystalline diamond (UNCD) coating on various substrates. Advanced Diamond Technologies, Inc. (ADT) has developed a new diamond coating technology that, unlike other diamond technologies, is extremely smooth and exhibits much lower friction as deposited, in addition to the hardness, wear resistance, and high thermal conductivity that makes diamond cutting tools superior to others. This project will focus on the application of this coating for the machining of titanium alloys. The outstanding strength-to-weight ratio of titanium and its alloys makes them ideal materials for many aerospace applications. However, titanium alloys are notoriously hard to machine, and aerospace companies are desperate for more reliable, longer lasting cutting tools. Diamond in principle is the ultimate material for this application, but current technologies produce tools that are too rough and lead to high cutting temperatures that are prohibitive for machining titanium which is very reactive with carbon. The result will be cutting tools that are less expensive yet will enable the UNCD cutting tools will also address a world-wide unsatisfied need for more robust yet affordable cutting tools to machine a variety of other advanced materials, including aluminum-silicon alloys, superalloys, and carbon composites. UNCD coated tools will yield much longer tool life, higher cutting speeds, lower cutting temperatures, higher precision, and will greatly accelerate the adoption of the world's hardest material to the toughest machining applications and result in improved products while saving money.

这个SBIR I期项目旨在使用一种新型的沉积技术开发光滑的钻石涂层切割工具，该技术在各种基板上提供了超纳米晶钻石（UNCD）涂层。 Advanced Diamond Technologies，Inc。（ADT）开发了一种新的钻石涂料技术，与其他钻石技术不同，它非常光滑，并且表现出较低的摩擦，除了硬度，耐磨性和高导热率外，还使钻石切割工具使钻石切割工具优于其他摩擦。该项目将重点介绍该涂层用于加工钛合金的应用。钛及其合金的出色强度与重量比率使它们成为许多航空航天应用的理想材料。但是，钛合金众所周知，钛合金很难加工，航空航天公司迫切希望更可靠，更持久的切割工具。原则上，钻石是该应用的最终材料，但是当前的技术生产的工具太粗糙，导致高削减温度，对于加工钛的加工温度非常高，这对碳非常有用。结果将是切割工具较便宜的工具，但可以使UNCD切割工具还可以解决全球范围内的不满意需求，以实现更健壮但负担得起的切割工具来加工各种其他高级材料，包括铝合金合金，超合金和碳复合材料。 UNCD涂层工具将产生更长的工具寿命，更高的切割速度，降低的切割温度，更高的精度，并将大大加速世界上最难的材料来实现最艰难的加工应用，并在节省资金的同时改善产品。
