Kupeza fakitale ya N04400 sikungofuna kupeza mtengo wotsika kwambiri - ndi za kupeza kukhulupirika kwa zinthu zisanayambe ngakhale kupanga. Tawonapo nyumba zambiri zapampu zikuphwanyidwa panthawi ya hydrotesting chifukwa satifiketi ya mphero sinafanane ndi kukana kwa dzimbiri kwa intergranular. Pamalo athu a Qingdao, billet iliyonse ya N04400-kaya mipando ya valavu ya AMS 5387-yogwirizana ndi cobalt-nickel kapena T800-alloy winch shafts-imatsimikiziridwa pawiri: kusanthula kwa spectrometric * ndi * ASTM B164 kuyesa kwamphamvu pa kutentha komweko. Umu ndi momwe timapewera zochitika "zovomerezeka koma zosokoneza" zomwe zimasokoneza nthawi ya OEM.
Chifukwa chiyani "fakitale ya N04400" imatanthauza zambiri kuposa kungoponya kapena kugudubuza
Kuchita zoona kwa N04400 kumadalira pa zinthu zitatu zomwe sizingakambirane: kukhazikika koyendetsedwa, kulekanitsa pang'ono, komanso mbiri yakale yotentha. Otsatsa ambiri amalemba zinthu ngati "N04400" pambuyo pofufuza zoyambira - koma kudumpha kutsimikizira kwa microstructure. Pochita, izi zimabweretsa kusagwirizana kwa makina: gulu limodzi limadula bwino pa 85 m / min; macheza otsatirawa pa 45 m / min, kukakamiza zida kusintha pakati pa kuthamanga. Fakitale yathu ya N04400 imaphatikiza kusungunuka kwa vacuum ndi kuwongolera kolimba. Ingot iliyonse imapangidwira ma dendritic spacing ndi sulfure stringer stringer-deta yomwe timagawana ndi makasitomala tisanadule. Kwa ma valve opanikizika amafunikira <0.5 μm Ra pamwamba kumaliza, izi zimachotsa kukonzanso kosakonzekera. Kwa nyumba za silinda za pampu ya piston zomwe zimagwira ntchito pa 4,000 psi, zimalepheretsa kuyambitsa kwa microcrack pansi pa kukweza kwa cyclic.
Pomwe ma N04400 okhazikika amalephera - komanso momwe timatsekera kusiyana
ASTM B164 imatanthauzira malire a mankhwala a N04400-koma sanena chilichonse chokhudza ma kinetics amtundu wa carbide precipitation. Ma mphero ena amapereka zinthu mkati mwazinthu zina koma amalephera kuyesa mapitting mwachangu mumadzimadzi amadzimadzi a chloride. Timathana ndi izi pogwira katundu yense wa N04400 pa 650 ° C kwa maola 2 pambuyo pa annealing, ndiyeno kuziziritsa mpweya. Izi zimakhazikitsa matrix a Ni-Cu motsutsana ndi leaching yosankha ndikusunga ductility. Makasitomala amafotokoza moyo wautali wa 3.2 × pamisonkhano yamapampu akunyanja pogwiritsa ntchito mankhwalawa. Mwachidziwitso, sitichitira magulu onse mofanana: sulfure zomwe zili ndi sulfure> 0.005% zimayambitsa nthawi yogwira ntchito; zotsalira za titaniyamu> 0.02% kusintha kozizira kozizira. Kusintha kwenikweni kwapadziko lapansi kumafuna kuyankha kwachitsulo munthawi yeniyeni-osati ma sheet okhazikika.
Kuchokera pa bar yaiwisi kupita ku gawo lofunikira kwambiri: mwayi woyimirira
Otsatsa ambiri a N04400 amayima pazakudya. Timayambira pamenepo—ndi kukhala ndi masitepe aliwonse pambuyo pake. Pamene OEM yaku Europe imafunikira milomo yofanana ndi 120 yamtundu wa cobalt ya jekeseni wotentha kwambiri, idatitumizira chojambula chokhala ndi ± 0.01 mm GD&T callouts ndi tsiku lomaliza la milungu 10. Izi ndi zomwe zinachitika: metallurgists athu adatsimikizira mbiri ya N04400 billet yotentha-ntchito poyamba; gulu lathu la CNC linayerekeza kugawa katundu wa chip kudutsa m'mizere yovuta yamkati; gulu lathu lomaliza linatsimikizira magawo a electropolish motsutsana ndi zofunikira za ASTM A967 passivation. Palibe ma handoffs. Palibe kuchedwa kwa chipani chachitatu. Malo aliwonse owunikira - kuchokera kuzinthu zomwe zikubwera CMM imasanthula mpaka malipoti omaliza oyeserera - amakhala mu ulusi umodzi wa digito. Ichi ndichifukwa chake 73% ya malamulo athu a N04400 ndikubwerezabwereza kwa gawo lomwelo.
Kusankha bwenzi lanu la fakitale ya N04400: mafunso atatu omwe amawulula kuthekera
- Kodi mungandiwonetse malipoti atatu omaliza a mayeso athunthu - kuphatikiza dzimbiri (ASTM G28 Method A) ndi kuyesa kwapang'onopang'ono mu 3.5% NaCl? Ngati akukayikira, QA yawo imayima pa chemistry.
- Kodi mumayika makina a N04400 m'nyumba kapena kunja mukatha kubereka? Makina osagwiritsa ntchito malo amasokoneza mbiri ya kutentha ndikuyika pachiwopsezo chambiri.
- Kodi pulogalamu yanu yotalika kwambiri ya N04400 ndi iti, ndipo ndi njira yanji yolephereka yomwe mudachotsa pobwereza ndondomekoyi? Mayankho amawulula ngati amaphunzira kuchokera kuzinthu zakumunda kapena ziphaso zongotumiza.
Takhala tikuyendetsa pulogalamu yofanana ya N04400 yapampu kwa zaka zisanu ndi zitatu. Magulu oyambilira adawonetsa kuyika kwa ma micro-pitting pamalo olumikizirana. Choyambitsa? Ming'ono ya manganese oxide inclusions yomwe imagwira ntchito ngati zolimbikitsa kupsinjika. Anakonza: anawonjezera kashiamu mankhwala kuti Sungunulani ndipo anayambitsa akupanga kumizidwa kuyeretsa chisanadze Machining. Kumeneko sikumangopanga-ndiko kuyang'anira zitsulo. Mukafuna kupanga kodalirika kwa Nickel Alloy 400, yambani pomwe nkhani ya zinthuzo imayambira-osati pomwe invoice imachita.
