Iyo umuntu avuze ngo 'incoloy part', benshi batekereza ko bavuga gusa amavuta ya nikel menshi arwanya ubushyuhe. Ubwo ni ubuso. Ikigaragara ni, ni icyemezo. Ntabwo utumiza gusa ibice; urimo kwiyandikisha kumurongo wose aho ubumenyi bwibintu nigice cyoroshye. Ikibazo nyacyo ni ugukora - gukina, gutunganya, kubyina ubushyuhe bwo kuvura. Nabonye ibishushanyo byinshi binanirana kuko bafataga Incoloy 825 cyangwa 925 nkicyuma cyiza cyane. Ntabwo aribyo. Ninyamaswa isaba kubahwa muburyo bwa mbere.
Igorofa Igorofa
Reka duhere aho bitangirira: gusuka. Hamwe nuruvange, cyane cyane chromium yo hejuru nka Incoloy 800H, igikonoshwa cyibikorwa ni bike kubijyanye nubuhanzi nibindi bijyanye no kugenzura ubugome. Igishushanyo cy'irembo ntabwo ari ugutemba gusa; ni icyerekezo cyo kugabanya kugabanya amarira ashyushye. Twize ibi inzira igoye kumurongo wimibiri ya valve imyaka yashize. Ibice byasaga neza, ariko igeragezwa ryumuvuduko ryagaragaje micro-ibice ku gice gisa nkicyaduka. Nyirabayazana? Igipimo cyo gukonjesha kidahuye mugice kinini. Ubushyuhe bwubushyuhe butandukanye bwari 30 ° C gusa kuva kuruhande rwa autoclave kugera kurundi. Nibyo byose byasabye.
Aha niho ibisekuru byerekana. Amaduka akora cyane cyane ibyuma bizagora. Umwirondoro wubushyuhe ni isi itandukanye. Ndibuka ko nasuye Ikoranabuhanga rya Qingdao Qiangsenyuan (QSY) igihe gito. Icyagaragaye ntabwo cyari ubushobozi bwitanura ryabo, ahubwo ni inyandiko zabo kubikorwa bya nikel. Zari zifite ikime cyihariye cyo kugenzura zinjiye mugihe cyumye kugirango zishishwe. Urwo rwego rurambuye rurakubwira ko barwanye urugamba rwo gukuramo amazi-na-gaze-porosity mbere. Imyaka 30 bamaze mu gukina ntabwo ari umubare gusa; ni isomero ryibibazo byakemuwe.
Nyuma yo kuvura ubushyuhe nubundi bucukuzi. Igisubizo gihuza ibi bice ntabwo ari 'shiraho kandi wibagirwe' cycle cycle. Igihe kiri mubushyuhe bukabije bwimvura ya karbide irakomeye. Gutinda cyane gutambuka, ukabona icyiciro cya sigma kumupaka wingano, ukica ubukana. Twigeze kubanza gusiba amazu menshi ya pompe kubera ko itanura ryari rifite ubushyuhe buke, bukoresha ubukonje bwa 25 ° C kuruta uko bwerekanwe. Ibice byanyuze mu igenzura ariko byacitse intege kubera guhangayika. Isomo? Impamyabumenyi ni nziza, ariko murwego rwo kwemeza ni byose.
Imashini: Aho Igitekerezo gihurira nigikoresho
Niba gukina ari gutwikwa kugenzurwa, gutunganya Incoloy ni intambara yo gukurura. Igipimo gikomereye akazi ni ubugome. Winjiye winjizamo gato, kandi mugihe uri 2mm mugukata, ibikoresho byakomanze mbere yigikoresho, biganisha ku gukata ku nkombe no kurangiza neza. Ntabwo ari imbaraga zamafarasi; bijyanye no gukomera no kudahwema kudahwema.
Porogaramu ya CNC kuri ibi bice ikeneye filozofiya itandukanye. Ntushobora gukoresha uburyo bumwe bwihuse, urumuri-pass wakoresha kuri aluminium. Byerekeranye n'umuvuduko muke, ibiryo byinshi, hamwe no guhora mubikorwa kugirango ugere munsi yakazi gakomeye. Coolant ntabwo ari iyo gukonjesha gusa; ni amavuta yo gukumira impande zombi. Nagize ibisubizo byiza hamwe numuvuduko mwinshi unyuze-igikoresho gikonjesha, mubyukuri kumena chip no kwoza mbere yuko yongera gusudira. Umufatanyabikorwa nka QSY, hamwe numurongo wabigenewe wa CNC kubisanzwe bidasanzwe, mubisanzwe ibikorwa remezo byahamagaye. Basobanukiwe ko gutunganya an Igice ntabwo ari akazi kuruhande rwishami ryabo ridafite umwanda.
Guhitamo ibikoresho biragaragara - ceramic cyangwa karbide hamwe na coatings yihariye. Ariko intwari itavuzwe cyane-intwari ni fixture. Ukeneye misa no gufunga ingingo zidatera guhuza guhindagurika. Ibiganiro byose bihita bikora-bigakomera hejuru, byangiza inzira ikurikira. Twigeze kumara iminsi ibiri tugerageza kumenya impamvu twabonye taper kumikorere yoroshye irambiranye. Yahinduye vacuum chuck yari ifite microscopique yamenetse, yemerera 5-micron flex. Kubikoresho byinshi, ntaho bihuriye. Kuri Incoloy 925, yahinduye imikorere kugirango isibe.
Umwihariko wa Alloys Niche na Real-Isi Yuzuye
Ijambo 'ibinure bidasanzwe' rijugunywa hirya no hino. Kubihimbano, akenshi bisobanura 'bihenze kandi bigoye.' Ariko kumukoresha wa nyuma mugutunganya imiti cyangwa kubyara amashanyarazi, bisobanura 'ikintu kidacika nyuma y'amezi atandatu mumigezi ishyushye.' Ngiyo agaciro kabuhariwe. Bakemura icyo cyuho mu gusobanukirwa.
Urebye umwirondoro wikigo nka QSY, interuro yingenzi ni uguhuza: shell mold casting, casting investment, hamwe na CNC gutunganya amavuta adasanzwe. Irahagaritse guhuza ibintu bigoye. Bisobanura ko bashobora gufata ibintu biteye ubwoba, bikikijwe n'inkuta Igice igishushanyo-vuga, umutwe uzunguruka ufite imiyoboro y'imbere-ubijugunye mu ishoramari kugeza kuri net-net, hanyuma urangize isura ikomeye yo gufunga kuri CNC, byose munsi yinzu. Ibikoresho ntabwo bigeze byoherezwa hagati y'uruganda rukora imashini, bigabanya ibyago byo kwanduza kandi, cyane cyane, bigakomeza ubumenyi bwibikorwa.
Nakemuye ubundi buryo: inzu yabakinnyi irashinja iduka ryimashini kuba ryarateje impagarara, iduka ryimashini rirega inzu yabakinnyi ahantu habi. Ninzozi mbi. Kwishyira hamwe bigabanya muri ibyo. Iremera ibisubizo. Ahari abakanishi basanga flange runaka ihora igoye gukata neza. Barashobora gusubira mumakipe yashinze hanyuma bagatanga igitekerezo cyo guhindura annealing cycle kuri iyo geometrie yihariye. Iyo ni zahabu ikora.
Kunanirwa nkigikorwa cyo guhatira
Ntabwo rwose wiga ibi bikoresho kugeza igihe ikintu kimenetse. Kimwe mubyo twananiwe kwiga ni ugushiraho inzira yo kuvura ubushyuhe ikozwe muri Incoloy 601. Gusaba byari byoroshye: gutwara ibice unyuze mu ziko. Bamaranye kimwe cya gatatu cyubuzima buteganijwe, bagabanuka nabi. Isesengura ryerekanye ko twasobanuye neza ibishishwa neza kugirango birwanye okiside, ariko twirengagije rwose imbaraga zinyanja munsi yumutwaro kuri ubwo bushyuhe bwihariye. Twari mumuryango ukwiye, ariko urwego rutari rwo. 601 nibyiza, ariko kubwumutwaro urambye kururwo rwego, DS (igisubizo-cyakemuwe kabiri) 800H yaba ihamagarwa.
Aha niho ibishushanyo mbonera byatoranijwe byananiranye. Bakubwira ikirwanya ruswa, ntabwo aricyo gifata ishusho munsi yuburemere bwacyo kuri 2100 ° F mumasaha 5000. Ubu bwoko bwa nuance nicyo wishyura hamwe nuwabikoze ufite uburambe. Bakoze amakosa ubwabo cyangwa babonye umukiriya ayikora. Iyo mbonye utanga urutonde rwerekana neza imiryango nka cobalt ishingiye kuri cobalt na nikel ishingiye kuri nikel, byerekana ko bamenyereye ibyo biganiro. Bazi ikibazo ntabwo gusa Urashobora kugikora? ariko Bizarokoka aho bijya?
Kwifata: Nubufatanye, Ntabwo Kugura
Noneho, mugihe ushakisha an Igice, ntabwo ugura gusa icyuma. Urimo kugura muburambe bwogutanga ibintu hamwe nubushyuhe bwumuriro, impinduka zicyuma cya metallurgiki, hamwe na fiziki yubugome bukabije. Igishushanyo ni intangiriro. Igikorwa nyacyo kiri mubiganiro: Ibi nibiki? Inzira yumuriro ni iki? Hoba hariho imihangayiko? Utanga isoko neza azabaza ibi bibazo. Ikintu gikomeye, kimwe nabafite imizi yimbitse haba mu guta no gutunganya inyamaswa, bizerekana ubundi buryo utari wigeze utekereza - guhindura radiyo nkeya kugirango utezimbere gutembera, kuruhuka kwihanganira kuzigama amasaha 20 yo gutunganya, urwego-rwiza rwa Incoloy.
Ubwanyuma, igice kigera kuri dock yawe nikimenyetso cyubufatanye. Ntabwo ari ibicuruzwa. Nibice byubuhanga byakemuwe, bikonjeshejwe kunangira cyane, byingirakamaro bidasanzwe. Intego ni uko icyo gice cyizewe bidasanzwe muri serivisi kuburyo buriwese yibagirwa ububabare byafashe kugirango abigire. Nibwo uziko wabikoze neza.
