*** 96-61626 Kirkpatrick This Small Business Innovation Research Phase I project will investigate the use of gas cluster ion beams to produce surface modification effects which have not previously been possible by any existing ion beam or direct energy beam method. Cluster ions have large total energy and very high mass and momentum in combination with low energy per individual atom. Impact of a gas cluster ion upon a solid surface involves a number of exceptional effects including generation of high momentary temperature pressure transients within an extremely shallow surface region at the impact site. It is believed that conditions can be produced within a graphite surface by means of gas cluster ion bombardment at room temperature which will cause tranformation of the graphite surface to diamond. The capability to produce carbon-to-diamond transformations will form the basis of a procedure for room temperature deposition of diamond coatings onto surfaces of virtually any material. Transient processing by gas cluster ions will become the basis for a low temperature method for growth of diamond coatings onto virtually any material. ***

* 96-61626柯克帕特里克 这个小企业创新研究第一阶段项目将研究使用气体团簇离子束产生表面改性效果，这在以前是不可能通过任何现有的离子束或直接能量束方法。团簇离子具有大的总能量和非常高的质量和动量，并且每个原子的能量较低。气体团簇离子对固体表面的撞击涉及许多异常效应，包括在撞击部位极浅的表面区域内产生高瞬时温度压力瞬变。据信，通过在室温下的气体团簇离子轰击，可以在石墨表面内产生条件，这将导致石墨表面向金刚石的转化。产生碳到金刚石转变的能力将形成在几乎任何材料的表面上室温沉积金刚石涂层的过程的基础。 通过气体团簇离子的瞬态处理将成为在几乎任何材料上生长金刚石涂层的低温方法的基础。 ***
