Uruganda rwinshi rwa cobalt rwibanze ibisubizo ntabwo aribyo kugura utubari twa alloy no kuyinyuza mumisarani. Barimo kugenzura microstructure mubice 10,000+-mugihe ufashe ± 0.015 kwihanganira mm kumiyoboro ikonjesha imbere muri cobalt alloy nozzle ikora kuri 850 ° C. Twakoze AMS 5387 ibice bya pompe ya hydraulic ya pompe ya offshore aho microcrack imwe muri zone yibasiwe nubushyuhe bivuze amadolari 240.000 mugihe cyo kumanura. Niyo mpamvu "uruganda rwa cobalt" atari ijambo ryishakisha gusa-ni urwego. Kurengana udafite disipuline ya metallurgjique, inzira ikurikirana, cyangwa ubushobozi bwo gutunganya imashini ya Hybrid, kandi uzahura nigipimo cyo gusiba hejuru ya 37%, gutinda kwa PPAP gutinda, cyangwa kunanirwa kumurima munsi yubushyuhe bwumuriro.
Imikorere yukuri ya cobalt itangirana nubunyangamugayo-ntabwo ari impapuro zemeza gusa. Cobalt-nikel superalloys nka T800 na AMS 5387 isaba kugenzura neza ingano y’ingano, ikwirakwizwa rya karbide, hamwe no gutandukanya interdendritic. Twabonye abakiriya banga ubushyuhe bwose kuko raporo y'ibizamini by'urusyo rutanga urutonde "ihura na AMS 5387”Ariko wasibye igisubizo annealing soak igihe nigipimo cyo gukonja. Mu myitozo, uko gusiba kwateje imburagihe mu nzu ya pisitori ya pisitori nyuma yamasaha 1.200 - ntabwo ari 5,000 nkuko byavuzwe. Uruganda rwibanze rwa cobalt rwemeza buri cyiciro kurwanya ingano ya ASTM E112, ikwirakwizwa rya karbide ya ASTM E1268, hamwe na sprosroscopi yangiza ikirere - ntabwo ari karubone na cobalt gusa. Ikurikirana ibikoresho fatizo kuva mu itanura kugeza ku gice cya nyuma ID, ikandika uburyo bwo gutunganya ubushyuhe mu mbonerahamwe yerekana ibishushanyo mbonera, hamwe no guhuza amakarita yerekana ikarita hamwe na coupons zipimishije zivuye muri casting imwe.
Ariko kugenzura ibikoresho byonyine birananirana nta bwubatsi bwubatswe bwubatswe. Cobalt ivanga akazi-gukomera cyane, guhinduranya ibikoresho hagati, no kubyara ubushyuhe butesha agaciro ubusugire. Imashini ya CNC yonyine ntabwo izatanga intebe ya valve intebe hamwe na Ra ≤ 0.4 µm na zeru munsi yubutaka bwera. Niyo mpamvu guhuza vertical bifite akamaro: casting igenzura umwanya wa dendrite; gutunganya neza neza bikuraho ububiko buhagije kugirango ugaragaze isura isukuye, yoroheje imihangayiko; nyuma yo gutunganya ubushyuhe bwo kuvura bigarura uburinganire bwicyiciro kitagoretse geometrike yoroheje. Mu kigo cyacu cyujuje ISO muri Qingdao, dukoresha ishoramari rya T800 ryuzuye mu gusya 5-axis - nta kugabanya imihangayiko hagati - kubera ko uburyo bwo kwigana ibikoresho byerekana uburyo bwo kwagura ubushyuhe bwa anisotropique mugihe cyo kurangiza. Twagabanije igihe cyizunguruka kuri AMS 5387 pompe yimyubakire ya 29% mugihe tunoza perpendicularité hagati yisura yimbere kuva kuri mm 0.08 kugeza kuri 0.022 mm. Ibyo bisobanuro biva muri CMM iyobowe na verisiyo yo kugenzura-ntabwo ari ubugenzuzi bwa nyuma.
Bamwe bavuga ko ibice bya cobalt “bihenze cyane ku buryo bidashobora kwemeza ibicuruzwa byakorewe ibicuruzwa.” Ariko imibare irahinduka mugihe ugereranije nigiciro cyose cya nyirubwite. Ibikoresho bimwe by’iburayi bya peteroli OEM yavuye mu byuma bitumizwa mu mahanga biva mu mahanga biva mu bindi bihugu biva mu mahanga - kandi bigabanya igiciro cya 18%. Mu mezi 14, basimbuye 32% by'ibyo byuma kubera isuri iterwa n'isuri kuri 22.000 psi. Isesengura ryabo rya TCO ryavuguruwe ryarimo guhagarika ibicuruzwa bitateganijwe ($ 18.500 / isaha), imirimo yo kongera gukora, hamwe no kwemeza NDT. Iyo basezeranye uruganda rwibanze rwa cobalt-aho gusobanura GD&T bibaho mbere yo gusubiramo, aho kwigana byerekana ko hashobora kubaho amashyanyarazi ashyushye mu majwi adasanzwe, kandi aho buri cyiciro kirimo raporo zemewe zemewe - igipimo cyatsinzwe cyaragabanutse kugera kuri 0.7%. Igiciro cyibice cyazamutseho 11%, ariko ubuzima bwigihe cyose mugushiraho bwagabanutseho 43%.
Uruganda rwizewe rwa cobalt ntirusezeranya "ubuziranenge bwinshi." Irabigaragaza - binyuze mu nyandiko zerekana guhuza ingano muri shitingi ya winch center, binyuze mumashanyarazi asubirwamo hejuru ya 300 mm cobalt alloy piston inkoni, binyuze mumutekano muke nyuma yamasaha 400 yumunyu-spray + ibizamini byamagare yumuriro kumpamvu ya pompe. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yubaka icyo kimenyetso muri buri cyiciro: kugenzura ibikoresho byinjira hamwe na sprometrometrique hamwe na ultrasonic test, mugikorwa cya CMM igenzura ibintu byingenzi bya datum, hamwe no kwemeza imikorere yanyuma ukoresheje hydraulic pression yangirika protocole ihuye nibisabwa na serivise. Intego yibanze ntigufi - sisitemu ya hydraulic, ibinyabiziga bya powertrain yimodoka, inteko zishinzwe kugenzura amavuta na gaze - ntabwo ari ukubera ubushobozi buke, ariko kubera uburyo bwihariye bwo kunanirwa (urugero, isuri ya cavitation muri cobalt nozzles, kwambara imyenda ya shitingi) bisaba gushishoza byubuhanga, ntabwo ari ibintu rusange. Kuri ba injeniyeri bagaragaza ibice byinshi bya cobalt, ikibazo ntabwo "Bashobora kubikora?" Ni "Bashobora kwerekana - igice kimwekimwe, icyiciro kimwekimwe - ko kizarokoka ibyo sisitemu yawe isaba?" Icyo kimenyetso nicyo gipimo cyonyine gifite akamaro.
