Mainjiniya akamatchula magawo a cobalt aloyi pamapampu a hydraulic, mavavu akumunda wamafuta, kapena makina opangira ma winchi apamwamba, sikuti amangogula zitsulo - akugula kukhazikika kwapang'onopang'ono pansi pa 300 ° C, kukana kuphulika m'malo otayirira, komanso kusasinthika kwapang'onopang'ono. Ndicho chifukwa chake "6 cobalt alloy part fakitale" si mawu otsatsa-ndilo gawo logwira ntchito. Zisanu ndi chimodzi sizimangokhala. Imawonetsa ziwerengero zochepera zotsimikizika, zobwerezabwereza zomwe zimafunikira kuti mugwiritse ntchito AMS 5387, T800, ndi ma superalloy ena a cobalt-nickel popanda kusokoneza kukhulupirika kwa malire ambewu kapena kubwereza kubwereza. Tawona makasitomala akusintha ogulitsa pambuyo pa magulu atatu omwe adalephera - nthawi iliyonse akudzudzula certification, koma tidazindikira kuti vuto lenileni linali losakwanira kuwongolera mpweya wa ng'anjo panthawi yothirira yankho.
Chifukwa Chake Zipata Zisanu ndi Ziwiri Zimatanthawuza Kudalirika kwa Cobalt Alloy
Ma aloyi a cobalt sapanga makina ngati chitsulo chosapanga dzimbiri. Amagwira ntchito molimba mtima, samatenthetsa bwino, ndipo amafuna njira zopangira zida zomwe zimayenderana ndi kuthamangitsidwa kwa chip ndi kasamalidwe ka matenthedwe. Fakitale yeniyeni ya 6 cobalt alloy simangokhala makina a CNC-ili ndi zipata zisanu ndi chimodzi zokhomedwa:
- Kufufuza kwazinthu mpaka kusungunula batch-palibe zilembo zamtundu wa "ASTM F75"; malipoti athunthu oyesa mphero okhala ndi zotsalira za oxygen/nitrogen zomwe zidalowetsedwa
- Pre-machining stress relief-Kukalamba koyenera kuwirikiza usanakhwime, osati mwachisawawa
- Toolpath-enieni kudula magawo-osati zokonzedweratu, koma zovomerezeka zovomerezeka / liwiro pamagulu a geometry (mwachitsanzo, ma nozzles opyapyala motsutsana ndi mapulagi olimba)
- Kutsimikizira kwa CMM m'magawo atatu ofotokozedwa-osati kuyendera komaliza kokha
- Kutsimikizira kukhulupirika kwapamtunda-kugwiritsa ntchito interferometry yoyera, osati miyeso ya Ra
- Kuyesa kogwira ntchito pamayendedwe oyeserera a kasitomala-kuthamanga panjinga, kukweza ma torque, kapena kukokoloka kusanatumizidwe
Muphonye chipata chimodzi, ndipo mupeza magawo omwe amadutsa macheke koma amalephera pa 12,000 PSI pambuyo pa mizungu 400. Tayeza kupsinjika kotsalira kopitilira muyeso mpaka +420 MPa m'zigawo za cobalt zopangidwa popanda mpumulo woyenera wa kupsinjika-zokwanira ku mbewu zazing'ono zosawoneka ndi NDT wamba.
Kumene Standard Casting-Machining Workflows Imawonongeka
Masitolo ena amaponya poyamba, kenako makina. Ena ma billets a makina. Sizimagwiranso ntchito modalirika pamapampu a cobalt alloy omwe amafunikira ± 0.015 mm concentricity pakati pa nkhope ndi nkhope ya flange. Chifukwa chiyani? Chifukwa kuchuluka kwa matenthedwe a cobalt kumasintha 12% pakati pa madera otenthedwa ndi kutentha - ndipo kuchepa kwa mchenga kumasiyanasiyana ndi 0.8-1.3% kutengera kuchuluka kwa nkhungu. Kukonzekera sikuli kocheperako kulolerana. Kuphatikizika kwa njira zosakanizidwa: ndalama zomwe zimapanga mawonekedwe apafupi ndi ukonde ndi 0.5 mm machining allowance, kutsatiridwa ndi kuchepetsa nkhawa * kusanachitike * kuchotsa chitsulo chilichonse. Kenako, ma axis angapo akutembenukira ndi zida zamoyo kuti agwire ID/OD coaxiality mkati mwa 0.008 mm-osati chifukwa makinawo ndi olondola, koma chifukwa mawonekedwe oyendetsa matenthedwe amasinthidwa ku gawo la alloy. Ndiko kuphatikiza koyima komwe mungathe kuyeza-osati kugulitsa.
Zochitika Zenizeni Zapadziko Lonse: Osati Zikalata Zokha
Pampu ina ya OEM yaku North America idanenanso kuti 22% yalephera msanga mumilomo ya aloyi ya cobalt yochokera kwa ogulitsa akuti "kutsata kwathunthu ISO 9001." Choyambitsa? Ma microcracks apamtunda omwe adayambitsidwa panthawi yotopetsa osathandizidwa - amangowoneka pansi pa 200x SEM. Wotsatsa wawo wotsatira, QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Ophatikizidwa ndi akupanga pamwamba pakupanga sikani pachipata chake chomaliza cha QC. Zotsatira: kulephera kwa nozzle kwa zero m'miyezi 18 pazida 37 zakunyanja. Palibe zamatsenga. Zongolembedwa pazipata zonse zisanu ndi chimodzi - kuphatikiza zotsimikizira za AMS 2269 zomwe zili ndi okosijeni, zomwe zimawongolera mwachindunji kung'ambika kwa T800.
Makasitomala samafunsa kuti "Kodi mumapanga magawo a cobalt?" Amafunsa "Kodi mungagwire 0.005 mm runout pa pulagi ya cobalt ya 120 mm m'mimba mwake mukusunga ≤22 HRC kuuma pamwamba?" Izi zimasiyanitsa ma lab ku mafakitale. Ndipo ikufotokoza chifukwa chake magulu a uinjiniya ku Germany ndi Singapore tsopano akuyendetsa zojambula zolemera za GD&T molunjika ku Qingdao-osati pamtengo, koma kuti afotokozere momwe angapangire ma angles, njira zochepetsera, ndi zowongolera zosokoneza kutentha zisanayambe zida.
Kusankha Mnzanu Wotsatira wa Cobalt Alloy: Macheke Atatu Osakambirana
Musanasaine RFQ, tsimikizirani izi—osati m’mabulosha, koma m’marekodi opangidwa:
- Funsani malipoti atatu omaliza a CMM pa gawo la cobalt alloy lomwe likugwirizana ndi geometry yanu-osati ma avareji, koma zopatuka zenizeni, kuphatikiza zipika za kutentha pakuyezera
- Pemphani ma chart a ng'anjo ya ng'anjo kuchokera kumayendedwe omaliza ochizira kutentha kwa AMS 5387-oxygen ppm iyenera kukhala pansi pa 25 panthawi ya annealing yothetsera vuto la sigma
- Tsimikizirani ngati kumaliza kwawo kumaphatikizapo electropolishing kapena kupaka makina-magetsi amachotsa kuwonongeka kwapansi; kukomoka kumabweretsa kupsinjika koma kumawopsa kuzungulira m'mbali zakuthwa za mita
Chizindikiro champhamvu kwambiri si certification. Ndimomwe amakuwonetsani mwachangu deta-osati satifiketi, koma manambala kumbuyo kwake. Chifukwa mu ntchito za cobalt alloy, mbiri imatha mpaka kulephera koyamba kwamunda. Kuchita kumatenga mpaka mkombero womaliza.
