Lapho onjiniyela becacisa izingxenye ze-Stellite ze-AMS 5387 zamaphampu asebenza ngogesi, amavalvu anomfutho ophezulu, noma amasistimu amawintshi asolwandle, abagcini nje ngokukhetha into ethile—bakhetha isiqinisekiso sokusebenza. I-AMS 5387 esekwe ku-Cobalt iletha ukumelana okukhethekile nokugwazwa, ukuhuzuka, kanye nokuwohloka kokushisa lapho izinsimbi ezingenasici ezijwayelekile zihluleka khona. Kepha ama-specs ezinto ezingavuthiwe asho okuncane ngaphandle kokubulawa okunembayo. Yingakho ukuthola kusuka ku- I-AMS 5387 ingxenye yefekthri ye-Stellite enokulawulwa kwensimbi okuqinisekisiwe, amandla aqinile e-GD&T, kanye nokulandelelwa kwenqubo okubhaliwe akuyona inketho—kubalulekile umgomo.
Kungani i-AMS 5387 Idinga Okungaphezu Kokusakaza nje noma Ukwenza Ngomshini
Sibone amaphrojekthi amaningi kakhulu emiswa esigabeni se-prototype ngoba abahlinzeki baphathe i-AMS 5387 njengenye nje ingxubevange. Akunjalo. Ukwakheka kwayo okuphezulu kwe-cobalt-nickel-chromium-molybdenum kuyenza ibe nzima kakhulu, isebenze kanzima ngesikhathi somshini futhi izwele ukushaqeka okushisayo ngesikhathi sokwelashwa kokushisa. Ukudlula okukodwa okune-geometry yethuluzi elingalungile kungadala ukuqhekeka okuncane. Umjikelezo wokupholisa osheshayo ngemva kokufakwa kwesisombululo ungashintsha ukusatshalaliswa kwe-carbide—impilo yokugqokwa eyehlisa isithunzi kuze kufike ku-40% ekuhlolweni kwenkundla. Ezivivinyweni zethu zokukhiqiza, sithole ukuthi izingxenye ze-AMS 5387 ezifakwe ngomshini ezintweni ezifakiwe ezigugile zibonise ubulukhuni obuphezulu obungu-22% (Ra > 1.6 µm) uma kuqhathaniswa nalezo eziqedwe kumathuluzi alinganiselwe, anesihloko se-PCD—futhi lowo mehluko uhlotshaniswa ngokuqondile nokuvuza kophawu ngaphambi kwesikhathi ezindlini zephampu ye-piston.
Yingakho ukuhlanganiswa okuqondile kubalulekile. An I-AMS 5387 ingxenye yefekthri ye-Stellite kufanele ilawule uchungechunge olugcwele: ukutholakala kwe-billet ye-T800-grade eqinisekisiwe, ukutshala izimali ngamazinga okuqinisa alawulwayo, ukukhulula ukucindezeleka ngaphambi komshini onzima, i-CNC ye-multi-axis ngesinxephezelo sokugqoka kwamathuluzi wesikhathi sangempela, kanye ne-HIP yokugcina (ukucindezela kwe-isostatic okushisayo) lapho kudingeka. Awekho ama-handoffs. Akukho ukuhlukahluka kwe-batch-to-batch ebulukhunini (HRC 38–45) noma ukuhlakazwa kwe-carbide.
Amakhono Amane Angaxoxiswana Kufanele Uwaqinisekise
Ngaphambi kokukhipha imidwebo, buza umphakeli wakho le mibuzo emine—futhi ufune ubufakazi:
- Ingabe uyawaqinisekisa amabhilidi angenayo e-AMS 5387 ane-PMI ephelele + nokuhlaziywa kwe-spectrographic? Siyenqaba u-3.7% wenkatho engenayo ngokusekelwe ekuchezukeni okuncane kwe-Mo/Cr—ngisho nangaphakathi kwemikhawulo ye-ASTM—ngoba kunomthelela ekwakhekeni kwesigaba sesibili ngaphansi kokulayisha umjikelezo.
- Ungakwazi yini ukubamba u-±0.015 mm kumadiamitha abalulekile wokuvala endaweni yesilinda engu-320 mm? Amandla ethu aqinisekiswe i-CMM kuma-cobalt alloys angu-±0.012 mm—hhayi “kufika” kodwa atholakala ngokuqhubekayo kuzo zonke izingxenye ze-serial ezingu-50+.
- Ingabe uyakwenza ukuhlola kwe-ultrasonic ngemuva komshini kuzo zonke izingxenye eziqukethe ingcindezi? Yebo—futhi sigcina amarekhodi aphelele wokuskena kwedijithali ahlanganiswe nenqwaba yokushisa kanye ne-ID yomsebenzisi.
- Ungakwazi yini ukuphindaphinda i-microstructure efana ne-cast ezindaweni esetshenzwe kabusha? Yebo, nge-laser cladding yendawo kusetshenziswa i-AMS 5387 powder enamakhemikhali afanayo, kulandelwa i-HIP nokuqeda imishini.
Lapho Abahlinzeki Abajwayelekile Beba Mfishane—Futhi Yini Esebenzayo Kunalokho
Abanye abakhiqizi bakhipha imishini ye-AMS 5387 ezitolo zemisebenzi ezijwayelekile. Sake sakuzama lokho. Umphumela? Amaqoqo amathathu anqatshiwe ngenxa yezimpawu zokuxoxa ezingaphansi komhlaba angabonakali ekuhlolweni kokubona—kodwa atholwe kuphela ngemva kwamahora angu-200 okuhlolwa kokugqokwa okusheshisiwe. Imbangela: ukungaqini ngokwanele kuma-mill-axis angu-3 kanye nokuntuleka kolwazi lwepharamitha yokusika ethize ye-cobalt.
Ukulungiswa kwakungeyona imishini eyengeziwe-kwakuyisiyalo senqubo ejulile. Manje sisebenzisa izikhungo zemashini ze-granite ezinebhedi engu-5-axis eqinile, eqinile ngokushisa enokulawula okupholisayo okudidiyelwe (±0.5°C), ukulingiswa kwendlela yamathuluzi okumodela ukulayishwa kwe-chip ngezinyo ngalinye *ngaphambi* kokusikwa, kanye nokuqinisekiswa kwenqubo yokuthinta-thinta ngemva kwayo yonke iphasi elibi. Kumajiyometri ayinkimbinkimbi njengamabhomu engxubevange ye-cobalt anamaphrofayela angaphakathi e-convergent-divergent, sihlanganisa ukufakwa kwe-investimenti kokuma kwe-close-net ne-electrochemical machining (ECM) ukuze kube ne-contour yokugcina—ukuqeda ukucindezelwa komshini ngokuphelele.
Ukusebenza Komhlaba Wangempela: Ukusuka Ekudwebeni kuya Ekusetshenzisweni Kwensimu
Ikhasimende elilodwa lalidinga ama-AMS 5387 center shaft roller amawintshi ezimoto zobunjiniyela basogwini lolwandle—kuncike ekucwilisweni emanzini anosawoti, ama-radial loads angu-120 kN, kanye nemijikelezo yokuqala yokumisa. Umhlinzeki wabo wangaphambili ulethe amarola ahlala amahora angama-4,200 okusebenza ngaphambi kokuthi kuqalwe ukugoba. Inguqulo yethu, enokuqondanisa okuthuthukisiwe kwenethiwekhi ye-carbide kanye ne-Ra ≤ 0.4 µm yokuqeda phansi, idlule amahora angu-11,800 ngesevisi efanayo—cishe izikhathi ezintathu zokuphila. Akukho ukuklama kabusha. Akukho ukuthuthukiswa kwezinto ezibonakalayo. Ukulawula okuqinile kokuthi kwenzekani phakathi kwesithando somlilo se-Foundry kanye nesiteshi sokugcina se-QC.
Lowo mphumela ukhombisa indlela i I-AMS 5387 ingxenye yefekthri ye-Stellite isebenza: hhayi njengomthengisi, kodwa njengesandiso sethimba lakho lobunjiniyela. Sibuyekeza ngokubambisana ama-callouts e-GD&T kusenesikhathi, sihlabe umkhosi izingozi zomshini ezingaba khona ezigabeni zerediya ezingajwayelekile noma ezinodonga oluncane, futhi sinikeze ngamadokhumenti agcwele e-PPAP—okuhlanganisa amashadi okuphatha ukushisa, imibiko ye-CMM, nezithombe zesakhiwo esincane—ngaphambi kokugunyazwa kwesihloko sokuqala.
Umcabango Wokugcina: Ukunemba Akukalwa kumaMicrons Wodwa
Ukusebenza kweqiniso ezingxenyeni ze-AMS 5387 kuvela ekuvumelaneni-hhayi nje ngobukhulu, kodwa ku-microstructure, iphrofayili ye-stress eyinsalela, nobuqotho bomhlaba. Lokho kudinga ukulinganiswa kwansuku zonke kwesinyathelo ngasinye senqubo, hhayi nje ukuhlola kwaminyaka yonke. Kusho ukwenqaba inkatho yokushisa ngokuchezuka kwekhabhoni okungu-0.03%—hhayi ngoba i-spec ivumela lokho, kodwa ngenxa yokuthi idatha yasenkambu ibonisa ukuthi isheshisa ukuguga okune-abrasive ezindaweni ezinodaka.
Uma iphrojekthi yakho elandelayo incike ezingxenyeni ze-AMS 5387 Stellite, bheka ngale kwezitifiketi. Cela amashadi asebenzayo angempela. Cela imibiko yokuhlolwa kwesampula kuma-oda akamuva emkhakheni wakho. Qinisekisa ukuthi basakaza *kanye* nomshini we-cobalt alloys—hhayi nje ukubamba. Ngoba ekugqokeni okuphezulu, izinhlelo zokusebenza ezinokwethenjelwa okuphezulu, umehluko phakathi "kwemisebenzi" kanye "ngeke yehluleke iminyaka engu-5" uhlala emininingwaneni engenalo uhlu lwedatha.
