Mayankho a fakitale apamwamba kwambiri a cobalt samakhudza kugula mipiringidzo ya alloy ndikuyiyendetsa kudzera pa lathe. Iwo ali pafupi kulamulira microstructure kudutsa 10,000+ mbali-pomwe akugwira ± 0.015 mm kulolerana pazitsulo zoziziritsa zamkati mumphuno ya cobalt alloy yomwe ikugwira ntchito pa 850 ° C. Tapanga zida za AMS 5387 zamapampu am'mphepete mwa nyanja pomwe ma microcrack amodzi m'malo okhudzidwa ndi kutentha amatanthauza $240,000 mu nthawi yopuma. Ndicho chifukwa chake "cobalt base fakitale" sikuti ndi mawu osaka-ndipo malire. Muwoloke popanda kuwongolera zitsulo, kutsata njira, kapena luso lopanga makina osakanizidwa, ndipo mudzakumana ndi ziwopsezo zopitilira 37%, kuchedwetsa kusaina kwa PPAP, kapena kulephera kwamunda chifukwa cha kuchuluka kwa matenthedwe ozungulira.
Kuchita kowona kwa fakitale ya cobalt kumayamba ndi kukhulupirika kwa zinthu - osati zolemba zotsimikizira. Ma superalloys a Cobalt-nickel ngati T800 ndi AMS 5387 amafuna kuwongolera kolimba pakugawa kukula kwa tirigu, carbide morphology, ndi tsankho la interdendritic. Tawona makasitomala akukana kutentha konse chifukwa malipoti oyesa mphero adalembedwa "amakumana ndi AMS 5387” koma yosiyidwa njira annealing zilowerere nthawi ndi kuziziritsa. M'malo mwake, kunyalanyaza kumeneku kunayambitsa kuphulika kwa silinda ya pampu ya piston pambuyo pa maola 1,200 - osati 5,000 monga momwe tafotokozera. Fakitale yeniyeni ya cobalt imatsimikizira batch iliyonse motsutsana ndi kukula kwambewu ya ASTM E112, kufalikira kwa ASTM E1268 carbide, komanso mawonekedwe owoneka bwino a spark emission - osati maperesenti a kaboni ndi cobalt okha. Imafufuza zinthu kuchokera ku ng'anjo ya ng'anjo kupita ku ID yomaliza, imasunga maulendo a kutentha kwa kutentha muzojambulira zamatchati okhazikika, komanso kulimba kwa mamapu akumapeto omwe ali ndi makuponi oyeserera omwe amachotsedwa pakupanga komweko.
Koma kulamulira kwakuthupi kokha kumalephera popanda zomangamanga zopangira zophatikizika. Cobalt alloys amagwira ntchito molimba mtima, amapotoza zida zodulira pakati, ndikupanga kutentha komwe kumawononga kukhulupirika. Makina a CNC okha sangapereke mipando ya valve yokhala ndi Ra ≤ 0.4 µm ndi zero subsurface yoyera wosanjikiza. Ichi ndichifukwa chake kuphatikizika koyima kuli kofunika: zowongolera zowongolera za dendrite mikono yotalikirana; makina olondola amachotsa katundu wokwanira kuti awonetse malo oyera, ochepetsa nkhawa; post-machining kutentha mankhwala kubwezeretsa gawo bwino popanda kusokoneza woonda-mipanda geometries. Pamalo athu ogwirizana ndi ISO ku Qingdao, timayendetsa malo opanda T800 oyika ndalama molunjika mu 5-axis mphero-palibe mpumulo wapakatikati - chifukwa njira yathu yofananira imatengera kukula kwa matenthedwe a anisotropic panthawi yomaliza. Tachepetsa nthawi yozungulira ya AMS 5387 mapampu anyumba ndi 29% pomwe tikuwongolera mawonekedwe pakati pa nkhope zokwera kuchokera pa 0.08 mm mpaka 0.022 mm. Kulondola kumeneko kumachokera ku chitsimikizo choyendetsedwa ndi CMM-osati kuwunika komaliza.
Ena amatsutsa kuti zida za cobalt "ndizokwera mtengo kwambiri kuti zitsimikizire kupanga mwachizolowezi." Koma masamu amasintha mukaganizira mtengo wathunthu wa umwini. Chida chimodzi chamafuta aku Europe OEM idasintha kuchoka ku mapulagi a aloyi a cobalt kupita kumayiko ena - ndikudula mtengo wagawo ndi 18%. M'miyezi ya 14, adasintha 32% ya mapulagiwo chifukwa cha kukokoloka komwe kunayambitsa kutayikira pa 22,000 psi. Kusanthula kwawo kosinthidwa kwa TCO kunaphatikizanso kutsekeka kosakonzekera ($ 18,500 / ola), kukonzanso ntchito, ndi kutsimikizika kwa chipani chachitatu cha NDT. Pamene adachita nawo fakitale yowona ya cobalt - komwe kutanthauzira kwa GD&T kumachitika asanatchulidwe, pomwe kuyerekezera kumaneneratu zoopsa zomwe zimang'ambika m'mabotolo osagwirizana, komanso pomwe gulu lililonse limaphatikizapo malipoti otsimikizika azitsulo - kulephera kwawo kudatsika mpaka 0.7%. Mtengo wa unit unakwera 11%, koma mtengo wamoyo wonse pakuyika unatsika 43%.
Fakitale yodalirika ya cobalt sikulonjeza "chiyero chachikulu." Zimatsimikizira izi - kudzera m'malumikizidwe ambewu yolembedwa mu ma winch center shaft rollers, kudzera muzitsulo zolimba zobwerezabwereza zodutsa 300 mm cobalt alloy piston ndodo, kudzera pakukhazikika kwakanthawi pambuyo pa mayeso amchere a maola 400 + otenthetsera njinga pamaziko a pampu. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imapanga umboni mu gawo lililonse: kutsimikizira kwazinthu zomwe zikubwera ndi spectrometry ndi kuyesa kwa ultrasonic, mkati mwa ndondomeko ya CMM imayang'ana zofunikira za datum, ndi kutsimikizira komaliza kwa ntchito pogwiritsa ntchito ma hydraulic pressure decay protocols ofanana ndi ntchito yomaliza. Cholinga chake chimakhala chocheperako - makina a hydraulic, zida zamagetsi zamagetsi zamagalimoto, makina oyendetsa mafuta ndi gasi -osati chifukwa alibe mphamvu, koma chifukwa njira zolephereka zamtundu wina (mwachitsanzo, kukokoloka kwa cavitation mu nozzles za cobalt, kuvala movutikira mu shaft rollers) zimafunikira chigamulo chaumisiri, osati ma generic Machining specs. Kwa mainjiniya omwe amafotokoza zinthu zoyera kwambiri za cobalt, funso siloti "Kodi angapange?" Ndi "Kodi angatsimikizire - gawo ndi gawo, gulu ndi batch - kuti lipulumuka zomwe dongosolo lanu likufuna?" Umboni umenewo ndiye metric yokha yomwe ili yofunika.
