The main results obtained by this project are as follows. And also one of another fruits of this project was a publication of journal named "Plasmas & Ions". It has been introduced due to the importance in the conception as the "Condensed Plasma" reaction which was firstly proposed by the head investigator in this project, was nucleated and constructed in this project and has been given the exellent appraise at the International Conference in Japan (Sept., 1998, Kokura) and China. (Oct., 1998 at Xian)2. A new fact that both the oxidation of N^<3-> ion and reduction of NO_3- ion can sythesize a TiN compound on metallic Ti electrode was found. And these results in condensed plasma reaction can introduce to synthesize the various other metallic nitrides such as FeNx. ZrN.WN.NbN..3. By means of XPS and Ramman spectroscopy, a second stage compound was covered with planar-sheet graphite fluoride which can protect the bulk graphite fluoroarsenates from the attack of moisture in air.3. It was … More cleared after the electrochemical measurments that a capacity of hydrogen absorbability in Pd-LI alloy was larger than metallic Pd.4. An attempt of DC discharging electrolysis improved in their circuit to be stable can produce metallic fine powder and expected to be a new method for metallic powder production.5. A thick nitride compound film with 100 - 200 mum was formed by a DC arcc plasma jet. X-ray micro-diffraction pattern and SEM microscopy revealed 3 different phases on the surface whose thickness were strongly depend on plasma gas ratio of N2/H2. By the spectroscopy of plasma flame in the range of 300 - 800 mum wave length, NH radical and H radical species were playing an important role in the synthesizing reaction.6. Effects of gravity on deposited metal morphology in the condensed plasma reaction were examined using drop shaft apparatus in JAMIC, the gravity has a certain effects on nucleation or growth rate in metallic deposition after comparing the SEM images of microcrystals electrodeposited with and without gravity.

该项目取得的主要成果如下。该项目的另一个成果是出版了《Plasmas & Ions》杂志，由于“凝聚等离子体”反应这一概念的重要性而被引入。该方案由本课题组长首次提出，并在本课题中核心构建，并在日本（1998年9月，小仓）和中国国际会议上得到了高度评​​价。 (1998年10月，西安) 2．发现N^<3->离子的氧化和NO_3-离子的还原都可以在金属Ti电极上合成TiN化合物，并导致凝聚等离子体反应。可以通过XPS和拉曼光谱来合成各种其他金属氮化物，例如ZrN.WN.NbN..3。表面覆盖有平面片状氟化石墨，可以保护块体氟化砷石墨免受空气中水分的侵蚀。 3．电化学测试表明，Pd-LI合金的吸氢能力比金属Pd大。 .4.改进了其电路的直流放电电解法，使其能够稳定地生产金属细粉，有望成为生产金属粉末的新方法。5． 200μm是由X射线微衍射图案和SEM显微术显示出表面上的3个不同的相，其厚度很大程度上取决于等离子体火焰中的N2/H2的比例。在300~800μm波长范围内，NH自由基和H自由基物种在合成反应中发挥着重要作用。6．重力对凝聚等离子体沉积金属形貌的影响。使用 JAMIC 的落轴装置进行了检查，通过比较有重力和无重力电沉积的微晶的 SEM 图像，重力对金属沉积的成核或生长速率有一定的影响。
