Xa iinjineli zicacisa iinxalenye ze-cobalt alloy kwiimpompo ze-hydraulic, i-oilfield valves, okanye i-high-wear-winch systems, azithengi nje isinyithi-zithenga uzinzo oluphantsi kwe-300 ° C ngebhayisikile eshushu, ukuxhathisa kwi-abrasive slurry environments, kunye ne-microstructural consistency kwi lot emva kweqashiso. Kungenxa yoko le nto "i-6 cobalt alloy part factory" ayilona ibinzana lokuthengisa-yinto esebenzayo. Isithandathu asifuni. Ibonisa ubuncinci benani lenkqubo eqinisekisiweyo, ephindaphindwayo yolawulo olufunekayo ukuphatha i-AMS 5387, T800, kunye nezinye ii-cobalt-nickel superalloys ngaphandle kokubeka esichengeni ingqibelelo yomda weenkozo okanye ukuphindaphinda kokugqiba. Siye sabona abathengi betshintsha ababoneleli emva kweebhetshi ezintathu ezingaphumeleliyo-ixesha ngalinye betyhola isiqinisekiso sezinto eziphathekayo, kuphela ukufumanisa ukuba i-bottleneck yokwenyani ibingonelanga ukulawula umoya womlilo ngexesha lokuvalwa kwesisombululo.
Kutheni iiGates zeNkqubo ezintandathu zichaza ukuthembeka kweCobalt Alloy
I-cobalt alloys ayisebenzisi njengentsimbi engenasici. Basebenza nzima ngokungqongqo, baqhuba ubushushu ngokungeyomfuneko, kwaye bafuna izicwangciso zezixhobo ezilungelelanisa ukufuduswa kwetshiphu nolawulo lobushushu. Umzi-mveliso we-cobalt wokwenyani we-6 we-cobalt ayingoomatshini be-CNC kuphela-unamasango amathandathu avaliweyo anamandla:
- Ukulandeleka kwezinto phantsi ukuya kwibhetshi yokunyibilika-akukho magama aqhelekileyo "ASTM F75"; Iingxelo ezipheleleyo zovavanyo lokusila kunye neoksijini / iintsalela zenitrogen ezifakiweyo
- Ukuphelisa uxinzelelo lwangaphambi komatshini-ukuguga kabini okunyanzelekileyo phambi kokuba urhabaxa, hayi ukukhetha
- Iiparamitha zokusika ezikhethekileyo-hayi i-presets, kodwa i-empirically validated feeds/isantya kwiklasi yejometri nganye (umzekelo, imilomo yodonga olubhityileyo vs. iiplagi eziqinileyo)
- Kwinkqubo yokuqinisekiswa kweCMM kwizitishi ezithathu ezichaziweyo—kungekhona nje uhlolo lokugqibela
- Ukuqinisekiswa komgangatho wentembeko-usebenzisa i-interferometry yokukhanya okumhlophe, kungekhona nje imilinganiselo yeRa
- Uvavanyo olusebenzayo kumjikelo womsebenzi owenziwe ngabathengi-Uxinzelelo lokuhamba ngebhayisikile, ukulayishwa kwetorque, okanye ukuvezwa kokhukuliseko ngaphambi kokuthunyelwa
Uphose isango elinye, kwaye uya kufumana iinxalenye ezidlula iitshekhi ezinobukhulu kodwa zisilele kwi-12,000 ye-PSI emva komjikelo we-400. Silinganise i-spikes yoxinzelelo lwe-tensile olushiyekileyo ukuya kuthi ga kwi-+420 MPa kwizinto ze-cobalt ezenziwe ngoomatshini ngaphandle koncedo olufanelekileyo loxinzelelo lwangaphambili-okwaneleyo kwimbewu ye-microcracks engabonakaliyo kwi-NDT eqhelekileyo.
Apho ukuCasa okuMgangatho-Machining Workflows yaphuka
Ezinye iivenkile ziphosa kuqala, emva koko ngomatshini. Ezinye iibhilikhwe zoomatshini. Ayisebenzi ngokuthembekileyo kwizindlu zempompo yengxubevange yecobalt ezifuna ±0.015 mm ukugxila phakathi kobuso kunye nobuso beflange. Ngoba? Ngenxa yokuba i-cobalt yokwandisa i-thermal coefficient itshintsha i-12% phakathi kwe-as-cast kunye ne-heat-treated states-kunye ne-santi casting shrinkage iyahluka nge-0.8-1.3% ngokuxhomekeke kwi-mold density. Ulungiso alukho ukunyamezela okungqongqo. Ukuhlanganiswa kwenkqubo ye-hybrid: utyalo-mali oluphosa imilo ekufutshane nenetha kunye ne-0.5 mm yesibonelelo somatshini, ilandelwa yi-annealing yokunciphisa uxinzelelo * phambi kokuba * naluphi na ukususwa kwentsimbi kuqale. Emva koko, i-multi-axis ijika kunye nesixhobo esiphilayo sokubamba i-ID / OD coaxiality ngaphakathi kwe-0.008 mm-kungekhona ngenxa yokuba umatshini uchanekile, kodwa ngenxa yokuba imodeli ye-thermal drift ilinganiswe kwi-alloy lot ethile. Olu ludibaniso oluthe nkqo onokuthi ululinganise — hayi ukuthengisa.
Ukusebenza kwehlabathi lokwenyani: Hayi nje izatifikethi
Ipompo enye yaseMntla Melika i-OEM inike ingxelo yokusilela kwangaphambili kwe-22% kwimilomo ye-cobalt alloy efunyenwe kumthengisi othi "ukuthotyelwa kwe-ISO 9001 ngokupheleleyo." Unobangela weengcambu? Ama-microcracks angaphezulu aqaliswe ngexesha lemisebenzi engaxhaswanga-ebonakala kuphela phantsi kwe-200x SEM. Umnikezeli wabo olandelayo, i-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Ifakwe kwi-ultrasonic surface integrity scanning kwisango layo lokugqibela le-QC. Isiphumo: Ukusilela komlomo ongunothi kwiinyanga ezili-18 kwiirigi ezingama-37 ezikude nonxweme. Akukho umlingo. Uludwe lwenkqubo ebhalwe nje kuwo onke amasango amathandathu-kubandakanya ukuqinisekiswa kwezinto ekrwada ngokuchasene ne-AMS 2269 yesiqulatho seoksijini, elawula ngokuthe ngqo ukukrazula okutshisayo kwi-T800 castings.
Abathengi ababuzi "Ngaba uyazenza iinxalenye ze-cobalt?" Babuza "Ngaba ungabamba i-0.005 mm runout kwiplagi ye-cobalt eyi-120 mm yedayamitha ngelixa ugcina ≤22 HRC yokuqina komphezulu?" Olo lwazi lwahlula iilebhu kwiifektri. Kwaye ichaza ukuba kutheni amaqela obunjineli eJamani naseSingapore ngoku ahambisa imizobo ye-GD&T-enzima ngqo ukuya eQingdao-kungekhona ngeendleko, kodwa ngengxelo yokwenziwa kwezinto kwii-engile eziyidrafti, ii-undercuts, kunye nezibonelelo zokuphatha ubushushu ngaphambi kokuba kuqale isixhobo.
Ukukhetha iqabane lakho elilandelayo leCobalt Alloy: Iitshekhi ezintathu ezingaxoxisiyo
Phambi kokuba usayine iRFQ, qinisekisa ezi—kungekhona kwiincwadana, kodwa kwiirekhodi zemveliso:
- Buza iingxelo ezintathu zokugqibela zeCMM kwinxalenye ye-cobalt alloy ehambelana nejometri yakho-hayi i-avareji, kodwa ukutenxa ngokwenyani koshicilelo, kubandakanywa iilog zobushushu ngexesha lomlinganiselo
- Cela iitshati zemozulu yesithando somlilo kumjikelo wokugqibela wonyango lwe-AMS 5387-i-oxygen ppm kufuneka ihlale ngaphantsi kwe-25 ngexesha lokucoca isisombululo ukukhusela i-sigma phase embrittlement
- Qinisekisa ukuba ukugqiba kwabo kubandakanya i-electropolishing okanye i-mechanical lapping-i-electro isusa umonakalo ongaphantsi komhlaba; i-lapping yenza uxinzelelo olucinezelayo kodwa ibeka umngcipheko wokujikeleza kwincam ezibukhali zemitha
Olona phawu lunamandla ayizozatifikethi. Yindlela abakubonisa ngayo ngokukhawuleza idatha-hayi isatifikethi, kodwa amanani emva kwayo. Ngenxa yokuba kwizicelo ze-cobalt alloy, idumela lihlala kude kube kukungaphumeleli kwentsimi yokuqala. Ukusebenza kuqhubeka kude kube ngumjikelo wokugqibela.
