Xa umntu ekhankanya iTribaloy, into yokuqala ehlala ifika engqondweni yile 'laa cobalt alloy inzima kakhulu'. Kodwa oko kukwenza lula okunokukukhokelela ezantsi kwindlela engalunganga ngexesha loyilo okanye lokukhangela. Akunjalo nje ngobulukhuni; imalunga nendibaniselwano ethile yokumelana ne-galling, ukuxhathisa umhlwa, kunye nokugcina iipropati kumaqondo aphezulu. Ndibone iiprojekthi zizinzile kuba i-spec isanda kubizwa ngokuba 'yi-Tribaloy' ngaphandle kokuchaza ibakala-T-400, T-800, T-800C-ziziphatha ngendlela eyahlukileyo. I-cobalt ephezulu kunye nomxholo we-molybdenum kunye nesakhiwo sesigaba seLaves singundoqo, kodwa indlela eqhutywe ngayo yenza okanye iphule inxalenye.
Inyani yoMatshini kunye noKubumba
Makhe siqonde ngqo kwindawo yentlungu: ukwenza i-Tribaloy yibhere. Ihlala ibonelelwa njengento yokuphosa, indlela enengqiqo yokuya kwiimilo ezinzima. Ukuzama ukuyifaka kwi-bar edibeneyo kunye nezixhobo eziqhelekileyo ze-carbide yindlela ekhawulezayo yokutshisa ngebhajethi yakho kunye nokufakwa kokutshabalalisa. Umsebenzi wezinto eziphathekayo unzima kakhulu. Uthatha inxeba, kwaye umphezulu osanda kudlula kuwo uba nzima ngakumbi. Sifunde kwangethuba ukuba udinga ukuseta okuqinileyo, iijiyometri ezikhangayo, kwaye ngamanye amaxesha ude ubhenele ekusileni okanye i-EDM yokunyamezelana okubalulekileyo. Ayingomatshini okhawulezayo; 'ngumatshini smart' enye. Ukuhamba okupholileyo akunakuxoxisana-kwaye kungekhona nje ukupholisa, kodwa ukuthintela i-micro-welding of chips.
Apha kulapho intsebenziswano nesiseko esaziyo izinto zayo ibaluleke kakhulu. Inkampani efana Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), kunye namashumi amathathu eminyaka kwiqokobhe kunye nokuphosa utyalo-mali kwii-alloys ezikhethekileyo, inokwenza ipateni kunye nolawulo lwenkqubo ukufumana ukuphosa kufutshane nokubunjwa komnatha. Eso sisiqingatha sedabi esiphumeleleyo. Ufuna oomatshini abancinci be-post-cast kangangoko kunokwenzeka. Ndikhumbula iprojekthi yeringi yesitulo sevalve apho imizobo yokuqala yayifuna ibhloko eqinileyo yeTribaloy T-400 ukuba ivalwe. Iindleko zoomatshini zazilingana neenkwenkwezi. Siyihlengahlengise ngokutsha nge-QSY ukuba ibeyi-invest-net-shape ye-investment casting, enqumla ixesha lomatshini malunga ne-70%. Amava abo ngokutya kunye nokuqiniswa kwezi ngxubevange ezisekelwe kwi-cobalt zithintele i-shrinkage porosity ebusweni obubalulekileyo bokunxiba.
I-Welding okanye i-brazing Tribaloy kwi-substrate, njengentsimbi, inxalenye egqunyiweyo sesinye isicelo esiqhelekileyo. Apha, ukungahambelani kokwandiswa kwe-thermal kunye nesiseko sesinyithi ngumbulali othuleyo. Ukuba inkqubo ayibizwanga—preheat, interpass temp, isihluzi esithile esinje ngeStellite 6 okanye ialloy esekwe nickel—ufumana iintanda. Akusoloko kwangoko, kodwa emva kwemijikelo embalwa ye-thermal enkonzweni. Yindlela yokusilela yakudala. Ukunyaniseka komgca webhondi yinto yonke. Sibe nempumelelo nge-vacuum brazing yezinye izinto ezikumgangatho ophezulu we-aerospace, kodwa yinkqubo efuna ucoceko olugqibeleleyo kunye noyilo lwesakhiwo.
Ukukhetha iBanga: Akunjalo nje i-T-400
Uninzi lwabantu alugqibekanga kwi-T-400. Lihashe lokusebenzela, elilungileyo lokumelana nokunxiba macala onke. Kodwa ukuba ukwindawo engcolisayo kakhulu, yithi ngeekloridi okanye iiasidi, iT-800 enomxholo wayo ophezulu wechromium lolona bhejo lungcono. Urhwebo-off? Abanye bathi ingaphantsi kancinane kokuqina kune-T-400, kodwa kwimeko yokunxitywa kwe-corrosion, iya kudlula i-T-400 ngomda obanzi. I-T-800C yongeza ikhabhoni ukuze ikwazi ukuxhathisa i-abrasion, kodwa qaphela ukuba brittleness kwiimeko zempembelelo. Kufuneka ufanise ibakala kunye nemeko yenkonzo yangempela, kungekhona nje inkcazo yekhathalogu.
Ndibandakanyeke kwisicelo semkhono sempompo seplanti yokulungisa imichiza. Inkcazo yokuqala yayiyi-T-400. Iye yasilela kwiinyanga nje ezimbalwa ngenxa ye-corrosion edityaniswe ne-abrasive slurry wear. Sitshintshele kwi-sleeve ye-T-800, ethathwe njengenxalenye echanekileyo yokuphosa ukuze kugcinwe ukuzinza kwe-dimensional yodonga olucekeceke, kwaye ubude bobomi bunyuke ngesine. Ixabiso lokuqala lemathiriyeli laliphezulu, kodwa ixabiso lilonke ngeyure nganye yokusebenza liye lehla. Olu luhlobo lwexabiso lobunjineli oluvela kumava ezinto eziphathekayo, kungekhona nje iphepha ledatha.
Enye i-nuance yi-microstructure yokuphosa. Inkqubo yokuphosa elawulwa kakuhle evela kwi-special foundry kufuneka ivelise ukusabalalisa okufanayo kwesigaba seLaves esinzima kwi-matrix ye-cobalt. Ndibone i-Tribaloy iphosakele kakubi apho isigaba seLaves sidityaniswe, sisenza iindawo ezibuthathaka kunye nokuqalisa iintanda phantsi komthwalo. Esi ayisosiphene onokusibona ngokulula ngohlolo olubonakalayo; kunokufuna uhlalutyo lwemetallographic. Xa ukhangela, awuthengi nje i-alloy, uthenga ukuhambelana kwenkqubo emva kwayo.
Imigibe yeSicelo kunye noLungiso lweHlabathi lokwenyani
Isicelo sakudala se Iindawo ze-Tribaloy alloy ikwimigangatho egugileyo: amahlahla, amatywina, izitulo zevalvu, imikhono yempompo. Kodwa impazamo eqhelekileyo kukusebenzisa kuyo yonke indawo kwindibano. Iyabiza. Uyilo olukrelekrele lusebenzisa kuphela apho ukunxitywa okuqatha okanye ukukrala kwenzeka, rhoqo njengokufakela okanye ukoleka okudityanisiweyo. Ukuyila indlu okanye indawo yokukhwelana ukusuka kwinto enokusetyenzwa ngakumbi, efana ne-316 engenastainless, kwaye emva koko ucinezele-faka okanye ukudibanisa i-Tribaloy insert yinkqubo eqhelekileyo.
Ukwandiswa kobushushu kuluma abantu apha. Ukuba uyila i-tight press-fit-fit kwiqondo lobushushu begumbi, ngaba iya kukhululeka okanye icinezeleke kakhulu kubushushu bokusebenza? Kufuneka wenze izibalo. Sasinecala elinomkhono othwele isomisi sobushushu obuphezulu. Umkhono we-Tribaloy wawufakwe kwindlu yentsimbi. Kwi-ambient, ukulingana kwakugqibelele. Kwi-500 ° C, insimbi yanda ngaphezu kwe-Tribaloy, ekhokelela ekulahlekelweni kokuphazamiseka kunye nokugqibela kokujikeleza komkhono. Ulungiso yayikukutshintsha ubalo olufanelekileyo olusekwe kubushushu bokusebenza, hayi iqondo lobushushu bendibano, kwaye kusetyenziswe ikhompawundi yokugcina ubushushu obuphezulu njengogcino.
Ukugqiba yenye inkcukacha. Ukutywinwa komphezulu, uhlala ufuna ukugqitywa okuhle kakhulu. Ukugaya kuyenzeka kodwa kucotha. Ngamanye amaxesha, ukuqhwaba linyathelo lokugqibela. Injongo ayisosiphelo sesipili, kodwa ngumgangatho ongaguquguqukiyo, osicaba ongayi kugalela inyongo kumlingane waso. Kwamanye amatywina aguquguqukayo, siye sachaza i-coating encinci phezu kwe-Tribaloy ukugcina i-lubricant-kodwa leyo yinkqubo ekhethekileyo.
Ukubonelela kunye neNyaniso yoBonelelo
Awuvele uodole iinxalenye ze-Tribaloy kwikhathalogu njengokuba ubuya kwenza ama-304 eebrakethi ezingenasici. Yi-volume ephantsi, i-specialty yexabiso eliphezulu. Amaxesha okukhokela made, ngakumbi ukuba ufuna i-castings yesiko. I-ingot ye-alloy eluhlaza ngokwayo yinto elawulwayo. Yiyo loo nto ukwakha ubudlelwane kunye nomboneleli onobuchule kukusebenzisana ngakumbi. Baye baba lulwandiso lweqela lakho lobunjineli.
Inkampani efana QSY (ungafumana amandla abo apha https://www.tsingtaocnc.com) ngumzekelo walo mzekelo. Imbali yabo ende yokuphosa kunye nokwenza ii-alloys ezikhethekileyo zithetha ukuba banokucebisa malunga nokwenziwa koyilo kwasekuqaleni. Abayovenkile yoomatshini nje; bayayiqonda isinyithi esivela eziko ukuya phambili. Kwicandelo lamva nje le-actuator ye-aerospace, siye sadlula kwimijikelo emithathu ephindaphindwayo kunye nabo-ukulungelelanisa iindawo zesango kwipatheni ye-wax, i-parameters yonyango lobushushu-ngaphambi kokuba sitshixelwe kwinkqubo yokuvelisa. Loo ntsebenziswano yeyona nto iqinisekisa Iindawo zeTribaloy ngokwenene ukwenza endle.
Enye indlela-ehamba neyona xabiso lincinci kwivenkile yomatshini jikelele ethenga nje isitokhwe sebha ye-Tribaloy-phantse isoloko iluqoqosho lobuxoki. Baza kusokola ngobuchwephesha, izinga lokwala liya kuba phezulu, ixesha lokukhokela lizakuvuthuza, kwaye unokuphela nenxalenye enoxinzelelo olushiyekileyo okanye iintanda ezincinci ezibangela ukusilela kwangaphambi kwexesha. Ixabiso lilonke lobunini likukuthembeka, hayi ixabiso leyunithi kwiPO.
Iingcamango Zokuqukumbela: Ngumdlalo weeNgcali
Ekugqibeleni, ukusebenza kunye ne-Tribaloy ayisiyiyo into odlala kuyo. Ifuna intlonipho yeempawu zemathiriyeli kunye neemfuno zayo zokusetyenzwa. Amabali empumelelo avela kwingcinga ehlanganisiweyo: uyilo lokwenziwa kwezinto (ekukhethwa ukuba kwenziwe), ukhetho oluchanekileyo lwebakala, ulawulo lwenkqubo ecokisekileyo, kunye neqabane lobonelelo olufumanayo. Asiyonto yorhwebo.
Ukungaphumeleli, kumava am, ngokuqhelekileyo kulandelela emva ekuyiphatheni njengenye-ezama ukugcina iidola ezimbalwa kwisiphelo sangaphambili ngokunciphisa inkqubo okanye umthengisi. Noko ke, xa isebenza, icombulula iingxaki phantse ezingenakukwazi ukwenza ezinye izinto. Icandelo elenziwe ngokufanelekileyo le-Tribaloy kwisicelo esifanelekileyo yinto oyifakayo kwaye ulibale ngayo iminyaka, eyona nto incoma kakhulu onokuyinika inxalenye yokunxiba.
Ngoko ke, ukuba uyayichaza, yimba nzulu kunegama legeneric. Cinga ngomjikelo opheleleyo wobomi: indlela oza kwenziwa ngayo, indlela oza kufakwa ngayo enkonzweni, kunye nento eza kujongana nayo apho. Kulapho ubunjineli bokwenyani ngezi iindawo zengxubevange kwenzeka.
