9860390 This Small Business Innovation Research (SBIR) Phase I project will develop a new ceramic cutting tool material for machining titanium alloys. Only limited success has been achieved by new coatings to prevent dissolution of carbon from current tungsten carbide tools into titanium. Phase I will develop a new class of ceramic-composite cutting tools based on yttrium-aluminum garnet (YAG), whose mechanical properties are similar to those of alumina and which are more compatible chemically with titanium. The research will make an initial thermodynamic phase compatibility analysis of reinforced YAG composites with titanium, experiment with YAG-based composite processing, characterize reactions occurring at the ceramic-titanium interface, and evaluate key mechanical properties. Titanium alloys, widely used in the aerospace industry, are one of the most difficult workpieces to machine. Their high reactivity limits the use of state-of-the-art ceramic tools. A new YAG-based, ceramic-composite cutting tool could reduce the costs of titanium alloy products by increasing machining rates and reducing production time.

9860390 这个小型企业创新研究 (SBIR) 第一阶段项目将开发一种用于加工钛合金的新型陶瓷切削刀具材料。 新涂层在防止当前碳化钨工具中的碳溶解到钛中仅取得了有限的成功。 第一阶段将开发一种基于钇铝石榴石（YAG）的新型陶瓷复合材料切削工具，其机械性能与氧化铝相似，并且在化学上与钛更相容。 该研究将对钛增强 YAG 复合材料进行初始热力学相相容性分析，进行基于 YAG 的复合材料加工实验，表征陶瓷-钛界面处发生的反应，并评估关键机械性能。 钛合金广泛应用于航空航天工业，是最难加工的工件之一。 它们的高反应性限制了最先进陶瓷工具的使用。 一种新型 YAG 基陶瓷复合材料切削刀具可以通过提高加工率和减少生产时间来降低钛合金产品的成本。
