Ibice byinganda zikora cyane ntibihanganira kumvikana-cyane cyane iyo bikorera munsi yumuvuduko wa hydraulic 300 bar, gaze ya gaze ya 600 ° C, cyangwa kwambara bikabije muri serivisi ya peteroli. Niyo mpamvu abajenjeri bo muri Tier-1 pompe OEMs hamwe na hydraulic sisitemu ihuza bigenda byirengagiza guhimba gakondo hanyuma bakerekeza kuri ifu y'icyuma metallurgie uruganda ibisubizo - ntabwo ari ugusubira inyuma, ariko nkinzira yonyine ifatika iganisha kumurongo uhamye, guhuza microstructural, no kwizerwa kumikorere mubice bya cobalt-nikel nka pompe ya AMS 5387 cyangwa T800 alloy nozzles.
Kuki Ifu Metallurgie Yatsinze Aho Gukora Byonyine Kunanirwa
Twabibonye inshuro nyinshi: umukiriya yohereje igishushanyo cya GD & T gikungahaye kuri cobalt alloy plug hamwe na 0.01 mm kwihanganira imyanya kumyenge itandatu ihumye - kandi iteganya ko ubugenzuzi bwurukuta rwa 0.005 mm kuri radiyo 120 mm. CNC ikora kuva kuri bilet ikomeye? Birashoboka - ariko ibipimo by'ibisigazwa bizamuka hejuru ya 40% kubera gukomera ku kazi, guhinduranya ibikoresho, no gukwirakwiza micro-crack muri AMS 5387. Gutera ishoramari? Umusaruro mwiza, ariko ibyago byo gukurura bitera 100% kwipimisha ultrasonic - kandi ntacyizere cyo gukwirakwiza karbide imwe.
Ifu ya metallurgie ikuraho icyo cyuho. Mugukanda cyane (HIP) ifu ya Co-Ni-Cr-Mo mbere yo gufatanyirizwa hamwe, dufunga hafi yubucucike bwa * * mbere yo gutunganya bwa nyuma. Igisubizo? Nta cyuho cy'imbere. Nta cyerekezo cyerekana ingano zidahuye. Nta kugoreka ubushyuhe mugihe cyo kuvura ubushyuhe. Kandi icy'ingenzi - nta mpamvu yo gukuraho 70% by'ibikoresho fatizo kugirango ugere kuri net net. Uruganda rukora amapompo yo muri Amerika ya ruguru rwagabanije igihe cyo kuyobora ku kigero cya 36% n’igiciro cyose kuri buri gice ku kigero cya 29% nyuma yo kuva mu gihimbano-ku-mashini kijya mu nzu ya silinderi ya HIP +.
Ubushobozi Bune butaganira ugomba kugenzura
Nukuri ifu y'icyuma metallurgie uruganda ntibisobanuwe no gutunga itangazamakuru-ripimwa nuburyo rigenzura cyane domaine enye zuzuzanya:
- Ibikoresho byoroshye: Buri cyiciro cya T800 cyangwa AMS 5387 yifu igomba gutwara urusyo rwuzuye - ntabwo ari ibihimbano gusa, ahubwo birimo ogisijeni (<150 ppm), ingano yubunini bwo gukwirakwiza (D50 = 15-25 µm), hamwe namakuru yimbitse. Twanze ifu yubusa idafite ibipimo bya HIP byemewe byinjira kuri buri mubare wubushyuhe.
- Indero ya HIP: Umuvuduko wonyine ntabwo wemeza ubucucike. HIP cycle yacu ifite 1150 ° C kuri 150 MPa mumasaha 3 - hanyuma ikonja kuri ≤5 ° C / min munsi ya argon. Gutandukana na 10 ° C cyangwa 10 MPa, kandi ushobora guhura nogukwirakwiza kutuzuye kubice bito.
- Inyuma ya HIP yerekana ubudahemuka: Ibice bya HIP bigabanuka muburyo butandukanye - kugeza 0.18% muburyo bukurikira, 0,09% muburyo bukabije. Porogaramu yacu ya CNC yishyura ikoresheje ikarita yo kugabanya ikarita ya laser, ntabwo ari offsets rusange. Nuburyo dufata ± 0.008 mm kuri piston bore ID nyuma yo gusya bwa nyuma.
- Kwemeza imikorere birenze CMM: Igipimo cyuzuye cyo guhuza ntacyo bivuze niba igice cyananiwe kugerageza. Twemeza buri cyuma cyimyubakire yimyubakire kuri 1.5 × igitutu cyakazi muminota 60 - hamwe nigihe cyo gushushanya ikarita ikoresheje ishusho ya sisitemu (DIC).
Iyo Hybrid Casting-Imashini ikubita PM Yera
Ibice bimwe birwanya inzira yifu yifu. Uruziga rwagati rwa shitingi rukenera kwambara T800 yo hanze-ariko intangiriro yacyo igomba gukuramo imitwaro itavunitse. Hano, ibyuma byumucanga byubatswe byinjira mumashanyarazi ya cobalt yashongeshejwe munsi ya vacuum, hanyuma HIP ifatwa nkigice kimwe. Imbaraga zinguzanyo zirenga 620 MPa-zagenzuwe na cross-section SEM / EDS. Abakiriya bagerageje kwambara babanje kuvuga ko basibye nyuma yizunguruka 4.200; verisiyo yacu ya Hybrid yatsinze 18.500 inzinguzingo mugice cya gatatu cyo gupima umunaniro.
Ibi ntabwo ari theoretical. Nicyo kiduha gutanga geometrike itari isanzwe-nka fondasiyo ya pompe irambiwe bidasanzwe hamwe numuyoboro wa coolant ihuriweho-byasaba gushiraho bitanu bitandukanye kubikoresho bisanzwe. Turabashiraho mubikorwa bibiri: HIP + ikarishye kurangiza kumashini 5-axis hamwe na live-ibikoresho na B-axis ihengamye.
Icyo Gusaba Mbere yuko Urekura PO
Baza uwaguhaye ibyo bibazo bitatu - hanyuma ugende niba ibisubizo bidafite umwihariko:
- “Nyereka ibiti bitatu bya nyuma bya HIP kuri AMS 5387 - byerekana igipimo cy'ubushyuhe bukabije, igihe cyo gutura, na raporo z'ibyuma nyuma ya cycle.”
- "Nigute ushobora kugenzura ko nta mikorobe iri munsi ya 25 µm? Ni X-ray CT, isesengura rya ultrasonic, cyangwa ibice byangiza?"
- "Niba igishushanyo cyanjye kigaragaza ASME B16.34 Icyiciro cya 900 cy'ingutu, ni ubuhe butumwa bwawe bwanditse bwanditse-kandi ni ikihe gipimo cy'amateka yawe?"
Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Ibyo biti birashobora kugenzurwa mumasaha 2. Ikizamini cyacu cyo kumeneka gikoresha helium mass spectrometrie kuri 1 pressure igitutu cyo gushushanya amasegonda 120 - igipimo cyatsinzwe: 99.87% hejuru yibice 14,200 byoherejwe kuva Q3 2022.Turasangira dosiye zuzuye zo kugenzura - ntabwo ari incamake - hamwe nibyoherejwe.
Kubice byingenzi-ubutumwa, ifu ya metallurgie ntabwo igabanya ibiciro. Nukuraho uburyo bwo gutsindwa mbere yuko binjira kumurongo wawe. Niba umushinga wawe utaha usaba AMS 5387, T800, cyangwa ibindi bice bisobanutse neza aho geometrie, ubunyangamugayo, hamwe nibisubirwamo bidashoboka-ukeneye ibirenze a ifu y'icyuma metallurgie uruganda. Ukeneye imwe ifata buri mubare wubushyuhe nkigikumwe cyintoki, buri cyerekezo cya HIP nkuburyo bwo kubaga, na buri raporo ya CMM nkinyandiko yemewe. Nibyo shingiro. Ikintu cyose gike gishobora guhura nigihe cyawe, garanti yawe, hamwe nicyubahiro cyawe.
