Xa iinjineli kunye nabaphathi bokuthengwa kwempahla befuna umzi-mveliso wenkampani yokubumba inaliti yesinyithi ephezulu, abafane bafune abathengisi bamayeza afana nalawo aqhelekileyo. Bafuna amaqabane aqondayo ukuba kutheni i-cobalt alloy nozzle ingaphumeleli kwi-650 ° C, indlela i-AMS 5387's boundary stability stability echaphazela ngayo ubomi bompompo wokudinwa kwezindlu, okanye kutheni i-GD & T callouts kwizindlu ze-piston cylinder ayikwazi "ukuqikelelwa" ekuphoseni-emva koko ikhutshwe. Leyo yinyani yokusebenza emva kwamacandelo asebenza kakhulu kwimizi-mveliso. Kwaye kulapho ulwahlulo lokwenyani luqala khona-kungekhona kwiincwadana, kodwa kwiilogi zokulandela umkhondo, ingxelo yeCMM evela kwiqashiso # A7291, kunye nochwephesha olungisa amazinga okutya phakathi kwe-machining ngenxa yokuba i-T800 billet's conductivity ye-thermal ifundeka nge-3% ngaphantsi kwe-spec.
Kutheni “Phezulu” Kuthetha Into ethile eNxibeleleyo kwiSitofu seNsimbi yokuBumba
"Phezulu" ayithethi malunga nokubalwa kwentloko okanye i-square footage yefektri. Kumalunga nokuphindaphinda phantsi koxinzelelo lwe-metallurgical. Umlingane we-MIM we-top-tier kufuneka aphathe i-cobalt-nickel alloys ngaphandle kwe-micro-cracking ngexesha le-debinding, ukulawula i-sintering shrinkage ukuya kwi-± 0.08 mm kumzimba we-valve ye-120-mm, kunye nokuqinisekisa ukusabalalisa ubuninzi kunye ne-ultrasonic attenuation mapping-kungekhona nje umgaqo ka-Archimedes. Uninzi lwabathengisi bama "senza iMIM." Abona bangcono baqala ngokubuza: Yeyiphi imowudi yokusilela ebonwa yinxalenye yakho yangoku? Ingaba indlela yomthwalo iphelela phi? Yintoni imfuneko yokugqiba umphezulu *kwi-interface esebenzayo*, hayi umda womzobo?
Siye sabona ukuqhekeka okuthathu okuphindaphindiweyo kwimithombo yehlabathi: Okokuqala, izikhewu zesiqinisekiso semathiriyeli-i-certs ze-mill zilahlekile iiparitha zonyango lobushushu okanye umxholo we-oxygen kwi-superalloys. Okwesibini, ukukhukuliseka okuphakathi kwiibhetshi ngenxa yokungahambelani kweeprofayile zokudinwa kwe-binder. Okwesithathu, i-porosity yomphezulu ayifundwanga ngendlela eyamkelekileyo kuba uhlolo olubonakalayo luthathe indawo yohlalutyo lwe-SEM olunqamlezileyo. “Ayiyomiba yobulunga” le. Ziyinkqubo yokusilela kokubonakala. Iifektri eziziphephayo zabelana ngophawu olulodwa: ukuhlanganiswa ngokuthe nkqo kwepowder prep, ukubumba, ukubopha, ukudibanisa, kunye ne-HIP-isigaba ngasinye sondla idatha yexesha langempela ukuya kwelinye.
Ubunzulu bobuGcisa phezu kwesikali: Apho ubuNjineli obuchanekileyo buhlala khona
Thatha iivalvu zoxinzelelo kwiinkqubo zamanzi. Isicatshulwa esisemgangathweni sicela ukunyamezela, umgangatho wezinto eziphathekayo, kunye nobuninzi. Ivenkile egxile ngokuchanekileyo icela imijikelo yoxinzelelo lokusebenza, ukuhambelana kolwelo (umzekelo, i-HFD-U synthetic vs. phosphate ester), nokuba umphezulu wokutywina udibana ne-elastomers okanye isinyithi ukuya kwintsimbi. Oko kutshintsha yonke into: i-sintering atmosphere (i-vacuum vs. hydrogen), i-post-HIP ihlola ingqibelelo yomphezulu, kunye nobukhulu begrit obusetyenziswa ekugqityweni kokugqibela.
- Imilomo ye-cobalt alloy ifuna ukukhula okuziinkozo okulawulwayo-ilungile kakhulu, kwaye ukuxhathisa ukukhukuliseka kwehla; rhabaxa kakhulu, kwaye iintanda ze-thermal ziyaqalisa
- I-AMS 5387 iinxalenye zempompo zifuna ukuntywila ngaphantsi kwe-1260°C ukugcina ukusasazwa kwesigaba se-gamma-prime
- I-T800 esekelwe kwi-winch shaft rollers idinga ukulinganisa umkhombandlela ngaphambi koyilo lokungunda-i-porosity kufuneka ilungelelanise ngokukhawuleza, kungekhona ngokungaqhelekanga.
Oku akuyothiyori. Siye sajonga izinto ezingama-47 ezingaphumelelanga ze-MIM ezisuka kuMzantsi mpuma we-OEMs zaseAsia kwiinyanga ezili-18 ezidlulileyo. I-63% ilandelelwe emva kokuguquguquka kwebhetshi ye-powder engaqinisekanga. I-22% ukuya kwiprofayili enxaxhileyo egqunywe ngamandla aluhlaza "amkelekileyo". Kuphela li-15% elibandakanyekayo kwiziphene zoyilo ezicacileyo. I-takeway? Iqabane lakho elikwinqanaba eliphezulu kufuneka libe ngumnikazi walebhu yokuchaza umgubo-okanye liphicothwe, ukufikelela kwikhontrakthi kwenye.
Ijongeka njani iTraceability yeReal-World
Ukulandelelwa ngokupheleleyo akuyobhokisi yokukhangela. Litsheyini: iqashiso elingumgubo okrwada → ilog yokwenziwa kwesibophelelo → i-ID yomgodi wokungunda → ijiko lobushushu lendawo yobushushu → irempu yoxinzelelo lwe-HIP → ulungelelwaniso lokugqibela lwe-CMM yokuskena. Ekomeleleni kwayo, inxulumanisa onke amabakala abalulekileyo kufundo oluchanekileyo lwe-thermocouple oluthathwe ngeyure yesithathu yokucula. Xa umthengi efaka iflegi ye-0.015-mm ngaphandle kokujikeleza kwi-cylinder yezindlu, impendulo akufanele ibe "siya kuphinda siyisebenze." Kufuneka kube: "I-Cavity #B7 ibonise i-0.012-mm ukwandiswa kwe-thermal ye-thermal kwi-1100 ° C-nantsi i-log yesithando somlilo kunye nesenzo sokulungisa esiye saphunyezwa kwi-Lot #A7302."
Elo nqanaba lokuphendula lifuna amaxwebhu ahambelana ne-ISO afakwe kwindlela yokusebenza-angafakwanga phezulu. Kuthetha ukutenxa kwilog yabaqhubi *phambi* kokucofa iqhosha elithi "umjikelezo wokuqala", hayi emva. Kuthetha ukuba umgubo ongenayo ufumana uhlalutyo lwe-XRF * kunye* nokusabalalisa ubungakanani besuntswana nge-laser diffraction-kungekhona nje uvavanyo lwe-sieve. Kuthetha ukuba yonke inxalenye egqityiweyo iphethe ikhowudi ye-QR edibanisa iwele layo elipheleleyo ledijithali: iziqinisekiso zezinto eziphathekayo, iiparitha zenkqubo, iingxelo zokuhlola, kunye ne-ID yomsebenzisi owenze ukuqinisekiswa okubonakalayo kokugqibela.
Ukukhetha iqabane lakho: Iikhrayitheriya eziSebenzayo, hayi iBuzzwords
Ngaphambi kokuba uthumele i-RFQ, buza le mibuzo mihlanu-kwaye ufune iimpendulo ezibhaliweyo:
- Ngaba ungabonelela ngeengxelo zokuqinisekisa ukufana kweqondo lobushushu besintering kwiilothi ezintathu zokugqibela zecobalt?
- Ithini i-oxygen ppm ephezulu evumelekileyo kwi-AMS 5387 iindawo eziluhlaza ngaphambi kwe-sintering-kwaye uyilinganisa njani?
- Sibonise ingxelo yokuthobela i-GD&T yecandelo elintsonkothileyo elinodonga olucekethekileyo (umzekelo, ≥10:1 ubude-ukutyeba umlinganiselo) ubuncinane ezintlanu eziyinyaniso
- Ukuqinisekisa njani ukufana koxinaniso ngapha kwe-150-mm yesiseko sempompo? (Iimpendulo ezamkelekileyo: micro-CT, i-ultrasonic velocity mapping. Ayivumelekanga: “standard density test”)
- Lithini ixesha lakho eliphakathi ukusuka ekubhaqweni kokungahambelani ukuya kwiingcambu ezibangela ukuvalwa kweziphene zeporosity yomphezulu?
Ukuba impendulo ibandakanya "silandela imigangatho yoshishino" okanye "iqela lethu lomgangatho liyiphatha loo nto," qhubeka ujonge. I umzi-mveliso wenkampani yokubumba inaliti yesinyithi ephezulu musa ukuchaza iinkqubo-ziyabonisa. Bathumela iingxelo ezinobukhulu kunye nayo yonke iprototype. Babelana ngokutyatyadula kwegophe phakathi kwamaqashiso. Bakuvumela ukuba uphicothe iilogi zabo zokufuma zokugcina umgubo.
Ikamva leleevenkile ezingayithathi iMIM njengendlela enqumlayo ekufutshane nenetha-kodwa njengenkqubo yokwenziwa kwesinyithi echanekileyo. Oko kuqala ngokwazi ngokuthe ngqo ukuba i-cobalt yakho ivela phi, ukuba i-binder yakho ibola njani, kwaye kutheni iprofayile yakho ye-sintering ibonakala ngathi ngumnwe-hayi itemplate.
