This Small Business Innovation Research (SBIR) Phase I project seeks to develop a diamond coating technology for steel that has the chipping and spalling resistance needed for commercial applications. Friction and wear between rolling, sliding, and cutting surfaces causes lost efficiency, reduced service life, and lost capital. For example, the loss of a bearing while drilling a deep oil well can cost $40,000 an hour in lost production. Diamond, which has a hardness that is twice that of cubic boron nitride (CBN) and four times that of silicon carbide (SiC), cannot be used in these commercial applications due to its poor spalling resistance. The innovation set forth in this proposal seeks to develop interfaces between the steel and diamond that will resist spalling of the film. Advanced computing techniques will be used to identify and evaluate the best prospects for a revolutionary substrate(steel)-interface-coating(diamond) system (Phase I deliverables). The commercialization of a chip-resistant diamond coating will facilitate the development of various advanced bearing and wear products including rolling and sliding bearings, engine parts, cutting tools, and biomedical devices.

这个小型企业创新研究(SBIR)第一阶段项目寻求开发一种钢的金刚石涂层技术，该技术具有商业应用所需的抗碎屑和抗剥落性能。滚动面、滑动面和切削面之间的摩擦和磨损会导致效率降低、使用寿命缩短和资本损失。例如，在深油井钻探时，轴承的损失可能会导致每小时损失4万美元的产量。钻石的硬度是立方氮化硼(CBN)的两倍，是碳化硅(SIC)的四倍，但由于抗剥落性较差，无法用于这些商业应用。这项提议中提出的创新寻求开发钢和钻石之间的界面，以抵抗薄膜的剥落。将使用先进的计算技术来确定和评估革命性的衬底(钢)-界面-涂层(钻石)系统(第一阶段交付成果)的最佳前景。抗切屑金刚石涂层的商业化将促进各种先进轴承和磨损产品的开发，包括滚动和滑动轴承、发动机部件、刀具和生物医学设备。
