Izixazululo zefekthri ezisezingeni eliphakeme ze-cobalt aziphathelene nokuthenga ama-alloy bars futhi uwasebenzise nge-lathe. Imayelana nokulawula i-microstructure kuzo zonke izingxenye ezingu-10,000+—ngenkathi ibambe ukubekezelela okungu-±0.015 mm eziteshini zokupholisa zangaphakathi kubhobho ye-cobalt alloy esebenza ku-850°C. Senze ngomshini izingxenye ze-AMS 5387 zamapumpu amaningi asebenza ngaphansi kolwandle lapho i-microcrack eyodwa endaweni ethinteke ukushisa isho u-$240,000 ngesikhathi sokuphumula. Yingakho "i-cobalt base factory" ingeyona nje igama lokusesha-iwumkhawulo. Iwele ngaphandle kwesiyalo se-metallurgical, ukulandeleka kwenqubo, noma amandla okumshini okuxubile, futhi uzobhekana namazinga okulahlwa angaphezu kuka-37%, ukulibaziseka kokungena ngemvume kwe-PPAP, noma ukwehluleka kwenkambu ngaphansi komthwalo oshisayo ojikelezayo.
Ukusebenza kwefekthri ye-cobalt yangempela kuqala ngobuqotho bezinto ezibonakalayo—hhayi nje amaphepha okunikeza isitifiketi. Ama-superalloy e-cobalt-nickel afana ne-T800 ne-AMS 5387 afuna ukulawula okuqinile ekusabalaliseni usayizi wokusanhlamvu, i-carbide morphology, kanye nokuhlukaniswa kwe-interdendritic. Sibone amakhasimende enqaba konke ukushisa ngoba imibiko yokuhlolwa komshini wokunikezela ifakwe ohlwini “ihlangana ne-AMS 5387” kodwa isixazululo esiyeqiwe sokucwilisa isikhathi kanye nezinga lokupholisa. Empeleni, lokho kweqiwa kubangele ukuqhuma ngaphambi kwesikhathi ezindlini zesilinda sephampu ye-piston ngemva kwamahora angu-1,200—hhayi angu-5,000 njengoba kucacisiwe. Imboni yesisekelo sangempela se-cobalt iqinisekisa zonke iqoqo ngokumelene nosayizi wokusanhlamvu we-ASTM E112, ukuhlakazwa kwe-carbide ye-ASTM E1268, kanye ne-spectroscopy yokukhishwa kwenhlansi eqondile—hhayi nje amaphesenti ekhabhoni nawe-cobalt. Ilandelela izinto ezingavuthiwe ukusuka esithandweni somlilo kuye engxenyeni yokugcina ye-ID, ifaka imijikelezo yokwelashwa kokushisa kumarekhoda eshadi alinganiselwe, kanye nemephu yokuqina kwereferensi yereferensi enamakhuphoni okuhlola aqinile akhishwe ekulingiseni okufanayo.
Kodwa ukulawulwa kwezinto ezibonakalayo kukodwa kwehluleka ngaphandle kwezakhiwo ezididiyelwe zokukhiqiza. Ama-alloys e-cobalt asebenza kanzima, ahlanekezela amathuluzi aphakathi nendawo, futhi akhiqize ukushisa okwehlisa ubuqotho obungaphezulu. I-CNC machining iyodwa ngeke ilethe izihlalo zevalvu yokucindezela ezine-Ra ≤ 0.4 µm kanye nesendlalelo esimhlophe esingaphansi kukaziro. Kungakho ukuhlanganiswa okuqondile kubalulekile: izilawuli zokusakaza i-dendrite ingalo yesikhala; ukunemba kwemishini kususa isitokwe esanele ukuze kuvezwe izindawo ezihlanzekile, ezidambisa ingcindezi; Ukwelashwa kokushisa kwangemva komshini kubuyisela ibhalansi yesigaba ngaphandle kokuhlanekezela amajiyometri anezindonga ezincane. Esikhungweni sethu esithobela i-ISO e-Qingdao, sisebenzisa izikhala ze-T800 zokutshala imali ziqonde ngqo ku-5-axis milling-akukho ukukhululeka kwengcindezi yamaphakathi-ngoba indlela yethu yamathuluzi yokulingisa ilandisa ngokunwetshwa okushisayo kwe-anisotropic ngesikhathi sokuqeda. Sehlise isikhathi somjikelezo we-AMS 5387 futha amaflange ezindlu ngo-29% ngenkathi sithuthukisa i-perpendicularity phakathi kobuso obukhuphukayo ukusuka ku-0.08 mm kuya ku-0.022 mm. Lokho kunemba kuvela ekuqinisekisweni kwenqubo okuqondiswa yi-CMM—hhayi ukuhlola kokugcina.
Abanye bathi izingxenye ze-cobalt "ziyabiza kakhulu ukuthethelela ukwenziwa ngokwezifiso." Kodwa izibalo ziyashintsha uma uhlanganisa izindleko eziphelele zobunikazi. Isisetshenziswa esisodwa senkundla kawoyela yaseYurophu i-OEM yashintsha isuka kumapulagi engxubevange ye-cobalt athengwa kwamanye amazwe yaya kwezinye izindawo ezitholakala endaweni—futhi yehlisa izindleko zeyunithi ngo-18%. Phakathi nezinyanga ezingu-14, bathathe indawo ye-32% yalawo mapulaki ngenxa yokuvuza okubangelwa ukuguguleka ku-22,000 psi. Ukuhlaziywa kwabo okubuyekeziwe kwe-TCO kufaka phakathi ukuvalwa okungahleliwe kwe-rig ($ 18,500 / ihora), ukusebenza kabusha, kanye nokuqinisekiswa kwe-NDT yenkampani yangaphandle. Lapho benza imboni yesisekelo se-cobalt yeqiniso—lapho ukuhumusha kwe-GD&T kwenzeka ngaphambi kokucaphuna, lapho ukulingisa ukulingisa kubikezela ingozi eshisayo yokudabula emibhobho engajwayelekile, nalapho iqoqo ngalinye lihlanganisa imibiko ye-metalography eqinisekisiwe—izinga lokuhluleka kwabo lehla lafika ku-0.7%. Izindleko zeyunithi zikhuphuke ngo-11%, kodwa izindleko zokuphila konke ukufakwa ngakunye zehle ngama-43%.
Imboni ethembekile ye-cobalt ayithembisi "ukuhlanzeka okuphezulu." Kuyakufakazela lokhu—ngokuqondanisa okubhaliwe kokugeleza kokusanhlamvu kumarola e-winch center shaft, ngokusebenzisa ama-gradients okuqina okuphindaphindayo kuwo wonke ama-cobalt alloy piston rods angu-300 mm, ngokuzinza kwe-dimensional ngemva kokuhlolwa kukasawoti-spray + wamahora angu-400 + okushisa wamabhayisikili ezisekelweni zephampu. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yakha lobo bufakazi kuzo zonke izigaba: ukuqinisekiswa kwezinto ezingenayo nge-spectrometry nokuhlolwa kwe-ultrasonic, i-CMM esenqubweni ihlola izici ezibucayi zedatha, kanye nokuqinisekiswa kokugcina kokusebenza kusetshenziswa izivumelwano zokubola kwe-hydraulic ezihambisana nezimo zesevisi yokusetshenziswa kokuphela. Ukugxila kwayo kuhlala kukuncane—amasistimu we-hydraulic, izingxenye zesitimela semoto yobunjiniyela, imihlangano yokulawula ukugeleza kukawoyela negesi—hhayi ngoba ingenawo amandla, kodwa ngenxa yokuthi izindlela zokuhluleka eziqondene nesizinda esithile (isb., ukuguguleka kwe-cavitation emibhobho ye-cobalt, ukugqokwa kwama-shaft rollers) kudinga ukwahlulela okushumekiwe kobunjiniyela, hhayi imininingwane yemishini ejwayelekile. Konjiniyela abacacisa izingxenye ze-cobalt ezihlanzekile kakhulu, umbuzo awukona ukuthi "Bangakwazi yini ukuwenza?" Ithi "Ingabe bangafakazela-ingxenye ngengxenye, iqoqo ngeqoqo-ukuthi izosinda kulokho okufunwa yisistimu yakho?" Lobo bufakazi ukuphela kwemethrikhi ebalulekile.
