Izisombululo ze-high-purity cobalt basefektri azikho malunga nokuthenga imivalo ye-alloy kunye nokuziqhuba nge-lathe. Bamalunga nokulawula i-microstructure kwiindawo ze-10,000 +-ngelixa ubambe ukunyamezela kwe-± 0.015 mm kwiishaneli zokupholisa zangaphakathi kwi-cobalt alloy nozzle esebenza kwi-850 ° C. Senze oomatshini be-AMS 5387 izixhobo zempompo ye-hydraulic ekude nonxweme apho i-microcrack enye kwindawo echatshazelwe bubushushu yayithetha i-240,000 yeedola ngexesha lokuphumla. Yingakho "i-cobalt basefektri" ayikho nje igama lokukhangela-lingumda. Yinqumle ngaphandle koqeqesho lwesinyithi, ukulandeleka kwenkqubo, okanye i-hybrid casting-machining isakhono, kwaye uya kujongana namazinga okulahlwa ngaphezulu kwe-37%, ukulibaziseka kokusayinwa kwe-PPAP, okanye ukusilela ebaleni phantsi komthwalo oshushu ojikelezayo.
Ukusebenza kwesiseko se-cobalt yokwenyani kuqala ngemfezeko yezinto eziphathekayo-hayi nje amaphepha esiqinisekiso. I-cobalt-nickel superalloys efana ne-T800 kunye ne-AMS 5387 ifuna ulawulo oluluqilima malunga nokuhanjiswa kobungakanani beenkozo, i-carbide morphology, kunye nokwahlulwa kwe-interdendritic. Siye sabona abathengi besala ukutshisa zonke ngenxa yokuba iingxelo zovavanyo lomthengisi zidweliswe "idibana ne-AMS 5387” kodwa isisombululo esishiyiweyo sokufunxa ixesha lokufunxa kunye nesantya sokupholisa. Ngokwenyani, oko kushiyiwa kubangele inkwankqa engaphambili kwipiston pump cylinder housings emva kweeyure eziyi-1,200—hayi 5,000 njengoko kuchaziwe. Umzi-mveliso wesiseko we-cobalt wokwenyani uqinisekisa yonke ibhetshi ngokuchasene ne-ASTM E112 ubungakanani beengqolowa, i-ASTM E1268 ye-carbide dispersion, kunye ne-spark emission spectroscopy ngqo-kungekhona nje iipesenti zekhabhoni kunye ne-cobalt. Ilanda imathiriyeli ekrwada ukusuka kwiqashiso le-ID ukuya kwinxalenye yokugqibela ye-ID, igcina imijikelo yonyango lobushushu kwiirekhoda zetshathi ezilinganisiweyo, kunye nemephu yobunzima beereferensi ezinqamlezileyo kunye namakhuphoni ovavanyo oluqinileyo atsalwe kwakwindlela efanayo.
Kodwa ulawulo lwezinto eziphathekayo lulodwa aluphumeleli ngaphandle kolwakhiwo oludibeneyo lwemveliso. I-cobalt alloys isebenza ngokungqongqo, ijikisa izixhobo phakathi, kwaye ivelise ubushushu obuthoba ingqibelelo yomhlaba. I-CNC machining iyodwa ayizukuzisa izihlalo zevalve yoxinzelelo kunye neRa ≤ 0.4 µm kunye ne-zero subsurface emhlophe umaleko. Yiyo loo nto udibaniso oluthe nkqo lubalulekile: ulawulo lokuphosa i-dendrite arm spacing; ukuchaneka kwe-machining kususa isitokhwe esaneleyo ukuze kuveze iindawo ezicocekileyo, ezithomalalisa uxinzelelo; unyango ubushushu post-machining ubuyisela ibhalansi isigaba ngaphandle kokuphazamisa iijiyometri ezibhityileyo. Kwiziko lethu elithobela i-ISO eQingdao, siqhuba i-T800 ye-investment-cast blanks ngqo kwi-5-axis milling-akukho ncedo oluphakathi loxinzelelo-kuba indlela yethu yokulinganisa i-akhawunti yokwandiswa kwe-anisotropic thermal ngexesha lokusikwa kokugqiba. Siye sanciphisa ixesha lokujikeleza kwe-AMS 5387 i-flange yezindlu zepompo nge-29% ngelixa siphucula i-perpendicularity phakathi kobuso obunyukayo ukusuka kwi-0.08 mm ukuya kwi-0.022 mm. Olo lwazi luchanekileyo luvela kwi-CMM ekhokelwa yi-in-process verification-hayi uhlolo lokugqibela.
Abanye baphikisa ukuba izinto ze-cobalt "zixabisa kakhulu ukuthethelela ukwenziwa kwesiko." Kodwa izibalo ziyatshintsha xa ujonga ixabiso elipheleleyo lobunini. Esinye isixhobo se-oilfield yaseYurophu i-OEM yatshintsha kwiiplagi zengxubevange ye-cobalt ephuma kumazwe angaphandle ukuya kwezinye iindawo ezifumaneka ekuhlaleni-kwaye yanciphisa ixabiso leyunithi nge-18%. Kwiinyanga ze-14, batshintshe i-32% yezo plugs ngenxa yokuvuza okubangelwa ukukhukuliseka kwi-22,000 psi. Uhlalutyo lwabo oluhlaziyiweyo lwe-TCO lubandakanya ukuvalwa okungacwangciswanga kwe-rig ($ 18,500 / iyure), ukuphinda kusebenze, kunye nokuqinisekiswa kwe-NDT yomntu wesithathu. Xa besenza isiseko somzi-mveliso we-cobalt wokwenyani-apho ukutolikwa kwe-GD&T kwenzeka ngaphambi kokucaphula, apho ukulinganisa ukulinganisa kuqikelela umngcipheko oshushu wokukrazula kwimibhobho engekho mgangathweni, kwaye apho yonke ibhetshi ibandakanya iingxelo zemetallography eqinisekisiweyo-inqanaba lokungaphumeleli kwabo lehla ukuya kwi-0.7%. Iindleko zeyunithi zinyuke nge-11%, kodwa iindleko zokuphila ngofakelo ngalunye zehle ngama-43%.
Umzi-mveliso othembekileyo we-cobalt awuthembisi "ukucoceka okuphezulu." Iyayingqina-ngolungelelwaniso lokuhamba okuziinkozo olubhaliweyo kwi-winch center shaft rollers, ngokusebenzisa ubulukhuni obuphinda-phindayo bobunzima kwiintonga zepiston ye-cobalt ye-300 mm, ngozinzo lwe-dimensional emva kweeyure ezingama-400 zetyuwa-spray + iimvavanyo zebhayisekile ezishushu kwiziseko zempompo. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yakha obo bungqina kuzo zonke izigaba: ukuqinisekiswa kwezinto ezingenayo kunye ne-spectrometry kunye novavanyo lwe-ultrasonic, i-CMM ye-in-process ihlola iimpawu ze-datum ezibalulekileyo, kunye nokuqinisekiswa kokugqibela kokusebenza kusetyenziswa iiprothokholi zokubola koxinzelelo lwe-hydraulic oluhambelana neemeko zenkonzo yokusetyenziswa kokuphela. Ugxininiso lwayo luhlala luncinci-iinkqubo ze-hydraulic, iinqununu zemoto yobunjineli be-powertrain, i-oyile kunye ne-gas flow control assemblies-kungekhona ngenxa yokuba ingenawo amandla, kodwa ngenxa yokuba iindlela zokungaphumeleli ze-domain-specific (umzekelo, ukuguguleka kwe-cavitation kwimibhobho ye-cobalt, i-fretting wear in shaft rollers) ifuna isigwebo sobunjineli esifakwe, kungekhona i-generic machining specs. Kwiinjineli ezichaza izinto ezicocekileyo ze-cobalt, umbuzo awukho "Ngaba banokuwenza?" "Ngaba banokungqina-inxalenye ngenxalenye, ibhetshi ngebhetshi-ukuba iya kusinda kwinto efunwa yinkqubo yakho?" Obo bungqina kuphela kwemetric ebalulekileyo.
