Boron Nitride (BN) Ceramics Yopangidwa Ndi WINTRUSTEK
Zoumba za Boron Nitride (BN) zili m'gulu la zoumba zaluso kwambiri. Amaphatikiza zinthu zosagwirizana ndi kutentha, monga matenthedwe apamwamba kwambiri, okhala ndi mphamvu ya dielectric yayikulu komanso kusagwira bwino ntchito kwamankhwala kuti athetse mavuto m'malo ena ofunikira kwambiri padziko lonse lapansi.
Boron Nitride ceramics amapangidwa mwa kukanikiza pa kutentha kwakukulu. Njirayi imagwiritsa ntchito kutentha kwa 2000 ° C ndi kukakamiza pang'ono kuti kupangitse kuti ufa wa BN usungunuke mumtambo waukulu, wophatikizana wotchedwa billet. Mabilu a Boron Nitride wa amatha kupangidwa movutikira ndi kumalizidwa kukhala zigawo zosalala, zovuta za geometry. Kuthekera kosavuta kopanda kuvutitsidwa ndi kuwombera kobiriwira, kupera, ndi glaze kumalola kuwonetsa mwachangu, kusinthidwa kwamapangidwe, komanso kuzungulira kwamaphunziro pamaukadaulo osiyanasiyana apamwamba.
Uinjiniya wa chipinda cha plasma ndi chimodzi mwazinthu zotere zomwe zimagwiritsidwa ntchito ndi Boron Nitride ceramics. Kukaniza kwa BN kutayira komanso kutsika kwapang'onopang'ono kwa ma ion achiwiri, ngakhale pakakhala malo amphamvu amagetsi amagetsi, amasiyanitsa ndi zida zina zapamwamba zam'madzi am'magazi. Kukaniza sputtering kumathandizira kulimba kwa zigawo zikuluzikulu, pamene kutsika kwa ma ion achiwiri kumathandiza kuteteza chilengedwe cha plasma. Yakhala ikugwiritsidwa ntchito ngati insulator yapamwamba m'njira zosiyanasiyana zopaka mafilimu, kuphatikizapo plasma-enhanced physical vapor deposition (PVD).
Kuyika kwa nthunzi wakuthupi ndi mawu a njira zambiri zokutira zopyapyala za filimu zomwe zimachitidwa mu vacuum ndipo zimagwiritsidwa ntchito kusintha pamwamba pa zinthu zosiyanasiyana. Nthawi zambiri anthu amagwiritsa ntchito sputtering deposition ndi PVD № kuti apange ndi kuyika zinthu zomwe akufuna pamwamba pa gawo lapansi popanga zida za optoelectronic, zida zolondola zamagalimoto ndi zakuthambo, ndi zinthu zina. Sputtering ndi njira yapadera yomwe plasma imagwiritsidwa ntchito kuti ipitirire kugunda chinthu chomwe mukufuna ndikukakamiza tinthu kuti titulukemo. Boron Nitride ceramics amagwiritsidwa ntchito kwambiri kutsekereza ma plasma arcs m'zipinda zopopera pa zinthu zomwe mukufuna komanso kupewa kukokoloka kwa zigawo zikuluzikulu.
Boron Nitride ceramics amagwiritsidwanso ntchito kupanga ma satellite Hall-effect thrusters kuti azigwira ntchito bwino komanso kukhalitsa.
Othandizira kuholo amasuntha ma satellite mu orbit ndikufufuza mumlengalenga mothandizidwa ndi plasma. Madzi a m'madziwa amapangidwa pamene njira ya ceramic yogwira ntchito kwambiri imagwiritsidwa ntchito popanga mpweya wotulutsa mpweya pamene imayenda mumlengalenga wamphamvu wa maginito. Malo amagetsi amagwiritsidwa ntchito kufulumizitsa plasma ndikuyiyendetsa kudzera munjira yotulutsa. Madzi a m’magazi amatha kuchoka pa tchanelo pa liwiro la makilomita masauzande ambiri pa ola. Kukokoloka kwa plasma kumakonda kuwononga njira zotulutsa za ceramic mwachangu kwambiri, lomwe ndi vuto laukadaulo wapamwambawu. Boron Nitride ceramics agwiritsidwa ntchito bwino kuonjezera moyo wa anthu otulutsa madzi a m'magazi popanda kusokoneza mphamvu zawo za ionization kapena kuyendetsa bwino.
