Anthu ambiri opanga zinthu akamamva 'cobalt base', nthawi yomweyo amaganiza 'ma injini a jet' kapena 'kutentha kwambiri' ndikuyima pamenepo. Ndiko kulakwitsa koyamba. Imayika zinthuzo kukhala kagawo kakang'ono, ndikukupangitsani kunyalanyaza zofunikira zake zenizeni, zopanda pake m'malo omwe simungayembekezere. Ndawonapo mapulojekiti ambiri osasinthika kukhala aloyi ya nickel chifukwa ndizomwe zimapangidwira kuti ziwonongeke, zimangolephera kuphatikizika ndi kutentha komwe kuli koyenera. maziko a cobalt kalasi akanapambana mwakachetechete. Mawuwo pawokha ndi olakwika pang'ono - si kobalt wangwiro; nthawi zonse ndi dongosolo lovuta, kulinganiza mchitidwe pakati pa ma carbides kuti asavale komanso kuti matrix olimba atha kulimbitsa. Kulakwitsa ndikokwera mtengo, ndipo ndili ndi zida zowonongeka kuti nditsimikizire.
Zowona Zofotokozera Cobalt Alloys
Simumangotenga aloyi ya cobalt. Mukusankha ndewu yolimbana ndi zikhalidwe zina. Ndi sulfidation? Kodi ikuphulika mu valve yothamanga kwambiri? Kodi ndi pampu shaft yomwe ikuwona kukokoloka kwa slurry pa 400 ° C? Kulephera kulikonse kumalozera ku banja losiyana. Stellite 6, yovala. Haynes 25 (L605) chifukwa cha kusakaniza kwa okosijeni ndi mphamvu. MP35N ikafuna mphamvu zamisala komanso kukana dzimbiri palimodzi, ngakhale chimenecho ndi chilombo cha cobalt-nickel-chrome-moly. Mapepala a data amakupatsirani katundu, koma samakuwuzani za kufuula kwa chida chopangira Stellite 12, kapena momwe kupsinjika kotsalira pazitsulo zomangika kumasokonekera ngati simukuyendetsa bwino kutentha kwapakati. Apa ndipamene zaka makumi atatu zakuchita zoyambira ndi kupanga makina, monga momwe mungapezere akatswiri ngati Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd., zimakhala zosakambitsirana. Iwo akhala pa izi kuyambira 90s, ndipo kuti kukumbukira mabungwe mmene kasungunulire zitsulo amachita kuchokera chitsulo chosungunula kuti chigawo chotsirizidwa ndi chimene chimalekanitsa gawo ntchito ndi udindo.
Ndikukumbukira pulojekiti yopangira valavu yothira malasha. Choyimiracho chimafuna kuti alloy-based alloy avale kwambiri. Tinapita ndi Stetellite yapamwamba ya carbon. Idachita moyipa kwambiri, idatenga milungu ingapo. Kufa kwa imfa kunasonyeza kuti sikunali kupsa mtima; chinali kuphatikiza kwa dzimbiri otentha kuchokera ku mankhwala a sulfure ndi micro-fretting. Kuuma kunali komweko, koma kukana dzimbiri kwa kalasi imeneyo kunali kolakwika. Tinasinthira ku carbon low, high-molybdenum maziko a cobalt zosiyana ndi kukana kwabwinoko kotentha kwa dzimbiri. Kusiyana kwake kunali usiku ndi usana. Kodi tikuphunzirapo chiyani? Nthawi zambiri mdani si chinthu chimodzi. Mufunika mnzanu amene amamvetsa zitsulo, osati makina.
Ndicho chifukwa chake ndondomekoyi ikufunika. Ndi ma aloyi awa, masitepe anu opanga amalankhulana. Kuzizira nthawi kuponya ndalama pa foundry ngati QSY zimakhudza mwachindunji kukula kwa carbide ndi kugawa. Kuthamanga kwambiri, ndipo mutha kupeza ma carbides abwino komanso osweka. Pang'onopang'ono, ndipo ma carbides amatha kukhala ovuta kwambiri, kuvulaza kukana. Kenako mumazipereka ku shopu ya CNC. Ngati amachichita ngati chitsulo chopangira makina, amawotcha ndikuyikapo ndikupangitsa kuwonongeka kwapansi panthaka. Mufunika magawo omwe amawerengera kuuma kwa ntchito komanso kutsika kwamafuta. Ndi njira imodzi yosalekeza, yodziwitsidwa kuyambira kukhuthula kupita kwina.
Machining: Kumene Chiphunzitso Chimakumana ndi Chida
Iyi ndiye fyuluta yayikulu. Mutha kukhala ndi mawonekedwe opangidwa mwangwiro, owoneka bwino maziko a cobalt chigawocho, ndi kuchiwononga pa lathe kapena mphero. Lamulo loyamba: kulemekeza ntchito kuumitsa. Ma alloys awa, makamaka olimba-njira yolimba ngati Haynes 188, amaumitsa pansi pa mphuno ya chida ngati muli wofatsa kwambiri. Muyenera kukhala ndi chakudya chokhazikika, chabwino ndi njira yakuthwa, yodzipereka. Kujowina ndi kutuluka? Ndilo njira yopangira malo owoneka bwino, owumitsidwa omwe angaphwanye chida chanu chotsatira.
Chida cha geometry ndi chilichonse. A lalikulu positive angatenge kukameta nkhani, osati kukankha. Kuziziritsa kwamphamvu kwambiri sikwapamwamba; ndizofunika kuyendetsa kutentha pamtunda, chifukwa kutentha sikuchoka ndi chip mosavuta. Tidalinganiza magiredi enaake a carbide ndi chithandizo cha post-coat pa ntchito izi. Ngakhale pamenepo, moyo wa zida umayesedwa ndi mphindi, osati maola. Mukukonzekera. Tsamba la makina a CNC pa tsngtaocnc.com si mndandanda wa mautumiki; ndikuvomereza mwachibwanabwana zomwe adayika mu zida zoyenera komanso kudziwa momwe angagwiritsire ntchito zida zamtundu uwu popanda kugwedezeka.
Mutu wothandiza: kubowola mabowo akuya. Kutsika kwamphamvu kwamafuta ndi kulimba kwake kumapangitsa kuthamangitsidwa kwa chip kukhala kowopsa. Mufunika zitoliro zofananira, zoziziritsa kukhosi nthawi zonse kudzera pa chida, komanso kulimba mtima kuti muthamangitse liwiro loyenera ndi ma feed. Musazengereze, ndi mapaketi a chip, kubowola kumayenda, ndipo mukuyang'ana zidutswa zamtengo wapatali kwambiri. Ndi luso lopangidwa kuchokera ku kuswa zobowola zambiri.
Kutulutsa Kwachitsulo: Kuposa Kusungunula Chitsulo Chokha
Kuponya nkhungu ya zipolopolo ndi kuponya ndalama ndi njira ziwiri zoyambira zovuta maziko a cobalt magawo. Iwo sasintha. Kwa ma geometri akuluakulu, osavuta, kuumba zipolopolo kuchokera ku maziko a QSY kumatha kukhala kotsika mtengo. Koma muyenera kuyang'ana zomwe nkhungu-zitsulo zimachita. Ma aloyi ena a cobalt amatha kuchitapo kanthu, ndipo silika mu chipolopoloyo imatha kupangitsa kuti pakhale vuto lapamwamba ngati makina omangirawo sali opangidwa. Ndi njira yomwe imafuna kuwongolera mwamphamvu kutentha kwa preheat kwa nkhungu ndi kutentha kothira.
Kuyika ndalama ndi njira yopangira mawonekedwe ovuta - taganizirani ma turbine nozzles okhala ndi ndime zozizirira mkati. Chigoba cha ceramic ndi inert, kotero kutsirizitsa pamwamba ndikwapamwamba. Koma apa, mdierekezi ali mu kudya ndi kulimbitsa. Ma alloys awa ali ndi kuzizira kosiyana. Mufunika zokwera zokonzedwa bwino komanso zotchingira kuti mupewe kutsika kwa porosity m'magawo okhuthala. Ndawonapo ma X-ray a zigawo zomwe zimawoneka bwino kunja, koma zimangowonetsa phata la spongy chifukwa mawonekedwe olimba sanapangidwe bwino. Apa ndipamene zaka zambiri zakupanga mapangidwe zimalipira. Si CAD yokha; ndikudziwa momwe mungasinthire mawonekedwe a digito kuti alipire kuchepa kwapadziko lapansi komanso kutsika kwamafuta, zomwe wogwiritsa ntchito kwanthawi yayitali amapangira njira yawo.
Ndiye pali kusungunula mchitidwe. Cobalt alloys nthawi zambiri amasungunuka kapena kusungunuka pansi pa mlengalenga wotetezera kuti ateteze makutidwe ndi okosijeni a zinthu zovuta, zogwira ntchito monga lanthanum kapena yttrium zomwe zimawonjezedwa kwa oxide scale adhesion. Simungathe kungoponya zidutswa mu ng'anjo yotseguka. Kuwongolera kwa chemistry kuyenera kukhala kosawoneka bwino, batch to batch. Kutchulidwa kwa ma aloyi apadera pa mbiri ya QSY si malonda; ndikulozera mwachindunji pamlingo uwu wa kuwongolera, kusungunuka kwamphamvu kwambiri.
Kuwotcherera ndi Kukonza: Masewera Apamwamba
Mwina iyi ndiye ntchito yovuta kwambiri. Kukonza chowonongeka maziko a cobalt Kuphimba pampando wa valve kapena kumanga shaft sikuli ngati chitsulo chowotcherera. Kuyika kwa kutentha ndikofunikira. Mochulukira, ndipo mumasungunula zitsulo zapansi mochulukira, kapena zoyipitsitsa, zimapangitsa kuti pakhale madzi ovomerezeka m'malo omwe amakhudzidwa ndi kutentha, ndikupanga magawo osasunthika omwe amasweka. Njira yomwe amakonda nthawi zambiri imapangidwa ndi GTAW (TIG) yokhala ndi waya wozizira, zomwe zimapangitsa kuti pakhale zigawo zolondola, zoonda.
Muyenera kufananiza zitsulo zodzaza osati ndi aloyi yoyambira, koma ndi momwe ntchito ikuyendera. Nthawi zina mumagwiritsa ntchito kaphatikizidwe kosiyana pang'ono kuti muwonetsetse kuti ming'alu imakanizidwa ndi chitsulo chowotcherera chomwe. Kutentha koyambirira kumakhala kofunikira, koma kutentha kwapakati ndizomwe mumayang'ana ngati kabawi. Lolani kutentha kwambiri, ndipo mutaya phindu. Ndakhala pamalo pomwe kukonza kudalephera kugwira ntchito chifukwa chowotcherera, chomwe chimakonda kukhala chosapanga dzimbiri, chimasunga ma pass osalola kuti gawolo lizizire mokwanira pakati pawo. Chotsatira chake chinali malo aakulu, osweka okhudzidwa ndi kutentha. Kukonzanso kumawononga ndalama zambiri kuposa gawo latsopano.
Zimatsogolera ku mfundo yotakata: mtengo weniweni wa ma aloyiwa sizinthu zopangira, zomwe zimakhala zosasunthika mokwanira. Zili m'machitidwe oyenerera, apadera ogwira ntchito ndi njira zoyendetsedwa zomwe zimafunikira pa sitepe iliyonse. Kugula kuchokera ku shopu yamakina ogwiritsira ntchito ndi chiopsezo chachikulu.
Beyond Aerospace: Mapulogalamu Osawoneka
Ngakhale kuti mlengalenga ndi mapeto ochititsa chidwi, ntchito zenizeni za mahatchi ndizonyansa komanso zimafuna zambiri mwa njira yawoyawo. Zida zotsika pansi zopangira mafuta ndi gasi.
