Measurement of metal vapor cooling speed during nanoparticle formation by pulsed wire discharge

Abstract：Pulsed wire discharge(PWD) is one of nano-sized powder production methods. The object of this work is to study influence of the plasma/vapor/particle density using computer simulation and to establish temperature measurement method using a high-speed infrared thermometer in the PWD process. The temperature correction coefficient was obtained from geometric computer simulation results. Obtained correction coefficient was applied to the temperature measuring results. It was found from this result that obtained correction coefficient was appropriate. A temperature measurement method was established by using the high-speed infrared thermometer in PWD. 作者： Author： Yuu SHIKODA[1]  Yoshinori TOKOI[2]  Koji SUWA[1]  Satoru ISHIHARA[3]  Tsuneo SUZUKI[1]  Tadachika NAKAYAMA[1]  Hisayuki SUEMATSU[1]  Koichi NIIHARA[1] 作者單位： Extreme Energy-Density Research Institute,Nagaoka University of Technology,1603-1 Kamitomiokamachi,Nagaoka,940-2188,JapanDepartment of Electrical and Electronic Engineering,Niigata University,2-8050 Ikarashi Nishiku,Niigata,950-2181,JapanInovertion Satellite Niigata,Japan Science and Technology Agency,NICO Techno-Praza 2F,4-1-9 Shinsan,Nagaoka,940-2127,Japan 期 刊： 中國有色金屬學(xué)報(bào)（英文版）   ISTICEISCI Journal： TRANSACTIONS OF NONFERROUS METALS SOCIETY OF CHINA 年，卷(期)： 2009, 19(z1) 分類號(hào)： Keywords： pulsed wire discharge    nano-sized powder    infrared thermometer    機(jī)標(biāo)分類號(hào)： V1 TM 機(jī)標(biāo)關(guān)鍵詞： during    infrared thermometer    computer simulation    measurement method    temperature correction    temperature measuring    PWD    influence    object    study    found    work 基金項(xiàng)目： Science and Technology Agency of Japan
