Lero tikambirana za electro-spark deposition's apply in metal alloys , nthawi yomweyo tidzayang'ana kwambiri paukadaulo uwu momwe mungasinthire nkhungu mu zida zomangira jakisoni ndi zisankho zoponya.
Kodi Electro-Spark Deposition ndi chiyani?
Electro-spark treatment, yomwe imadziwikanso kuti Electro-discharge Machining (EDM), ndi njira yapadera yopangira zinthu zomwe zimaphatikizapo kugwiritsa ntchito magetsi kuti apange ndikusintha pamwamba pa zitsulo.
Panthawi ya chithandizo cha Electro-spark, kutulutsa kwamagetsi kumapangidwa pakati pa elekitirodi ndi chogwirira ntchito, chomwe chimapangidwa ndi zinthu zopangira zinthu monga chitsulo kapena ma aloyi.Njirayi imayamba ndikuyika electrode, nthawi zambiri ngati chida chaching'ono, chowoneka bwino, pafupi ndi workpiece.
Pamene magetsi akugwiritsidwa ntchito pakati pa electrode ndi workpiece, kutulutsa kwamagetsi kofulumira kumachitika.Kutulutsa kumeneku kumapangitsa kutentha kwambiri, kusungunula tigawo tating'ono ta pamwamba pa chogwiriracho.Chitsulo chosungunukacho chimazimitsidwa mwachangu ndi dielectric fluid, kupangitsa kuti ikhale yolimba ndikupanga ma craters ang'onoang'ono kapena zolowera.
ESD imagwiritsidwa ntchito pazitsulo zazitsulo
Mphamvu ya capacitor ikatulutsidwa, mphamvu yachindunji imapanga kutentha kwakukulu kwa plasma pakati pa nsonga ya elekitirodi ndi chitsulo cha alloy workpiece.Kutentha kwakukulu kumeneku kumakhala pakati pa 8000 ndi 25000 ° C.Arc ya plasma imatulutsa anode ndipo imasamutsa zinthu zosungunuka kupita ku workpiece.
Anode iyi ya ionizing imasamutsidwa kupita ku gawo lapansi kudzera pamiyendo yayifupi.Arc yotentha kwambiri imakhala ndi tinthu tating'onoting'ono ta anode, mtsinje wa kutentha (jet yotentha), ndi madzi a m'magazi opangidwa ndi kuwonongeka kwa mpweya ndi maatomu a nitrogen, oxygen, ndi carbon.Kutentha kwakukulu kumayendetsedwa ndi ma jets amafuta ndi plasma.
Chifukwa chakuti ma pulse ndi aafupi, kutentha kwa kutentha kupyolera mu jet yotentha ndi mpweya wina kumakhala kochepa, ndipo kutentha kokha kutengera gawo lapansi ndi kudzera mu chiwerengero chochepa cha anode particles chomwe chimayikidwa pa gawo lapansi.Chifukwa chake, ma pulsewa amasamutsa kutentha pang'ono kupita ku gawo lapansi popanda kusintha kachulukidwe kakang'ono ka gawo lapansi.Njirayi ndiyothandiza kwambiri kuposa njira yowotcherera yophatikizika yomwe imagwiritsidwa ntchito pokonza ma aloyi omwe ali ndi zinthu zomwe zimakhudzidwa ndi kutentha (mwachitsanzo, kulimba pang'ono, kulimba kwambiri, kusweka kwa liquefaction).
Kuphatikiza apo, njirayi imathandizira kupanga mgwirizano wamphamvu wazitsulo pakati pa gawo lapansi ndi zokutira.Microalloying pakati pa electrode kusungunuka ndi gawo lapansi limayambitsa mapangidwe a plasma kupyolera mu kuwonongeka kwa mpweya, carbonates, carbides ndi nitrides.
Ubwino wake
1.Kulondola ndi Kulondola: Kuchiza kwa Electro-spark kumapangitsa kuti pakhale mawonekedwe olondola komanso olondola azinthu zovuta komanso zovuta kwambiri pazitsulo zazitsulo.Kutulutsa kwamagetsi komwe kumayendetsedwa kumawononga zinthuzo mowongolera, zomwe zimapangitsa kuti pakhale mawonekedwe enieni monga mabowo ang'onoang'ono, mipata, kapena ma indentation omwe ali olondola kwambiri.
2.Kusunga Umphumphu Wazinthu: Chimodzi mwa ubwino waukulu wa chithandizo cha Electro-spark ndi kuthekera kwake kusunga kuuma ndi kukhulupirika kwa workpiece.Mosiyana ndi njira zamakina zamakina zomwe zimatha kutenthetsa kwambiri ndikupangitsa kusintha kosafunikira kwazinthu zakuthupi, chithandizo cha Electro-spark chimachepetsa madera omwe amakhudzidwa ndi kutentha ndikusunga kuuma kwa chogwirira ntchito komanso kukhulupirika kwake.
3.Complex Geometries: Chithandizo cha Electro-spark chimathandiza kukonza ma geometries ovuta omwe angakhale ovuta kapena osatheka kuti akwaniritse ndi njira zamakono zamakono.Kutha kwake kupanga zinthu zovuta kumapangitsa kuti pakhale nkhungu, kufa, kapena zinthu zina zokhala ndi ma contour apadera komanso tsatanetsatane wovuta, kukulitsa kuthekera kwake.
4.No Tool Wear: Mosiyana ndi njira zamakina zachikhalidwe zomwe zimaphatikizapo kudula kapena kuphulika, chithandizo cha Electro-spark sichimakhudza mwachindunji pakati pa chida ndi workpiece.Chotsatira chake, pamakhala kuvala kwa zida zochepa, zomwe zimatsogolera ku moyo wautali wa zida ndi kuchepetsa mtengo wokonza.
Chidule
Nkhaniyi makamaka imayambitsa ndondomeko ya EDM popanga nkhungu, osati kungoyambitsa ndondomeko yake, komanso kuwonetsa ubwino waukulu wa ndondomekoyi.Kupyolera mu kanema pamwambapa, ndikuyembekeza kuti mutha kumvetsetsa ndondomekoyi momveka bwino.Ngati muli ndi mafunso ena, chonde omasukaLumikizanani nafe.
