Iyo inzu ya pompe hydraulic yamenetse kuri 420 ° C, cyangwa cobalt alloy nozzle ikananirwa nyuma yamasaha 380 muri serivisi ya gaze isharira, ntabwo uhura nikibazo cyimashini-uhura na ubushyuhe bwo hejuru cyane uruganda icyuho cyubushobozi. Twabibonye kenshi cyane: amatsinda yubwubatsi ashakisha AMS 5387 ibice biva mubikorwa rusange-bigamije, gusa twavumbuye microsegregation mubice bitunganijwe nubushyuhe, impeke zidahuye neza mubihimbano, cyangwa gutandukana kwa GD&T bigenda byinjira mumateraniro. Imikorere nyayo kwisi munsi yumukino wo gusiganwa ku magare, umuvuduko mwinshi, hamwe nibitangazamakuru bitesha agaciro ntibibabarira kugenzura ibintu bifatika cyangwa gutunga ibice.
Kuki "High-Temp Alloy" Atari Ikirango gusa-Ni Kwiyemeza Inzira
Ntabwo buri gihimbano cyujuje ibyangombwa nkukuri ubushyuhe bwo hejuru cyane uruganda. Benshi bakora nikel-ishingiye kuri nikel - ariko bake ni bo bakomeza gukurikiranwa neza kuva inyemezabuguzi ya T800 yemewe binyuze mubisubizo bifatika, guhuza imirongo myinshi, hamwe na CMM yagenzuwe neza. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Dufata amavuta ya cobalt-nikel ntabwo ari ibikoresho bidasanzwe, ahubwo nka sisitemu ifite impinduka zuzuzanya: igipimo cyo gukomera kigira ingaruka ku gukwirakwiza karbide; Urutonde rwimashini rugena imihangayiko isigaye mumazu ya silinderi yoroheje; ndetse no kuzimya ubushyuhe buciriritse buhindura delta hagati ya ASTM A995 Icyiciro cya CD4MCu hamwe no kurwanya ruswa nyayo mubutaka bwa peteroli bukungahaye kuri chloride.
Twigeze kongera kubaka inzu ya pisitori ya piston yananiranye yo gutera inshinge zo mu nyanja y'Amajyaruguru. Igice cyumwimerere cyakoresheje rusange IN718 ariko ntikigenzura kugenzura gukomera. Ivugurura ryacu ryatangije ubukonje bugenzurwa mugihe cyo gushora imari, hakurikiraho HIP + gusaza kabiri-kandi byongereye ubuzima bwa serivisi kuva kumezi 14 kugeza hejuru ya 42. Ntabwo byari byiza guhitamo amavuta. Byari casting-mashini-yubushyuhe bwo kuvura guhuza nta mucuruzi umwe ushobora gutanga.
Ubushobozi Bune butavuguruzwa Ntushobora gutanga hanze
Yizewe ubushyuhe bwo hejuru cyane uruganda igomba gutunga izi nkingi enye - ntizitange:
- Igisonga cyibikoresho: Ubufatanye bwa tekinike butaziguye hamwe ninsyo, ntabwo byateganijwe gusa. Tugenzura buri cyemezo cyubushyuhe bwa AMS 5387 kirwanya ingano ya ASTM E112, ingano yintoki ya ASTM E1268, hamwe na raporo yihariye yo gupima ruswa.
- Gutera - gutunganya imashini: Urufatiro rwumucanga rwibanze rushyirwa mubikorwa mbere yo kugabanya ibibazo. Ishoramari-cobalt nozzles irangiza-guhinduka * nyuma ya * HIP - ntabwo mbere. Ibi birinda kugoreka byangiza kwihanganira imyanya kuri 0.015 mm yukuri yibiranga.
- Gushyira mu bikorwa: Ntabwo ari "CMM yagenzuwe." Twifashishije optique ya profilometrie hejuru yikidodo, kwemeza laser tracker kumpamvu nini ya pompe (kugeza kuri m 2.8), hamwe no kugenzura-gukoraho-kugenzura kuri 5-axis CNCs - kubera ko gutwarwa nubushyuhe mugihe cyogukora cyigihe kirekire cyo gutunganya ibice byimbitse bya T800 bishobora guhindura umurongo wa 0.022 mm.
- Kwemeza imikorere. Nta "sample-only" idasanzwe.
Igiciro Cyihishe cyo Gucamo ibice
Abaguzi bamwe bagabanije akazi: guterera muri Fondasiyo A, kuvura ubushyuhe bwa Heat Treater B, kurangiza muri Machine Shop C. Ariko mugihe icyuma cya AMS 5387 gikora microcrake hafi yumuzi wurudodo, ninde ufite nyirabayazana? Fondasiyo A ivuga ko imiterere yabakinnyi bahuye na sp. Ubushyuhe B B yemeza ko ukwezi kwabo guhuye na datasheet. Imashini iduka C yerekana ibikoresho byinzira nziza. Hagati aho, umushinga wawe uranyerera ibyumweru bitandatu.
Twakurikiranye ibintu 31 byananiranye byoherejwe cyane mu myaka itatu ishize. 68% bakurikiranye intera iri hagati yintambwe zikorwa - ntabwo ari inenge yibikoresho. Uruganda rumwe rutunganya Aziya yo mu majyepfo y’iburasirazuba bwa Aziya rwanze ibyiciro 17 bya cobalt alloy plugs kubera ko hejuru yumucanga utari warakozwe mbere kugirango ukureho ibice bya decarburize mbere yo kuvura ubushyuhe. Urwo rwego rwahindutse urubuga rwa nucleation rwo gucamo munsi yumutwaro wumuriro. Igenzura ryuzuye rikuraho utwo duhumyi.
Icyo Usaba Uruganda Rwawe Ubushyuhe Bwinshi-Urubu
Mbere yo gushyira umukono kuri NDA, baza ibibazo bitanu-urebe uko bisubiza:
- "Twereke ibyemezo byawe bitatu bya nyuma bya AMS 5387 - hamwe na raporo ya microstructure ya nyuma ya HIP hamwe nisesengura rya morfologiya ya karbide."
- "Nigute ushobora kwemeza ituze rinini nyuma yo kuvura ubushyuhe ku bice bifite uburebure bwa 3: 1?"
- "Nubuhe bushyuhe bwawe bushoboka bwemewe hagati ya TIG mugihe cyo gusudira ibice bya cobalt-kandi ubikurikirana ute mugihe nyacyo?"
- “Urashobora gutanga ibisobanuro byuzuye ku nzu imwe ya pompe ya piston - kuva ku ndangamuntu yashonze kugeza kuri raporo y'ubugenzuzi bwa nyuma?”
- "Ni ikihe kigereranyo cyawe cya mbere cyo gutanga umusaruro kuri geometrike idasanzwe isaba <0.01 mm kwihanganira umwirondoro? ”
Niba ibisubizo bidasobanutse, byatinze, cyangwa kuvuga "amahame yinganda" uterekanye uburyo bwihariye bwo kugerageza - genda. Precision ntishobora kumvikana mugihe ikora kuri 70% yo gushonga.
Ubushyuhe bwo hejuru buvanze butangira kera mbere yo gukata cyangwa gusuka. Itangirana na disipuline ya metallurgjiya, ikurikizwa mugukina, gutunganya, no kurangiza - bidatangwa kumipaka yishami. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yubatse izina ryayo mu kwanga gucamo ibice. Ikigo cyacyo cyujuje ISO muri Qingdao ntabwo gikora ibice byujuje gusa. Itanga ibice bikomeza kurokoka ibyo spes idafata: umunaniro wubushyuhe, isuri yuduce, kwinjiza hydrogène, hamwe nibisabwa bidasubirwaho kuri zeru zitateganijwe. Iyo gusaba kwawe gusunitse hejuru ya 500 ° C, kurenga 10,000 psi, kurenga ibyiciro bisanzwe byujuje ubuziranenge-nibihe byukuri ubushyuhe bwo hejuru cyane uruganda Kureka guhitamo.
