Xa abantu abaninzi besiva 'i-investment casting alloy', bacinga ngoko nangoko ngezinto eziqhelekileyo-316 stainless, mhlawumbi 17-4PH. Yimpazamo yokuqala leyo. Ingxubevange ayiyonto nje oyiodolayo; yiyo yonke iprofayile yokuziphatha ukusuka kwinyibilika ukuya ekugqibeleni. Ndibone imizobo emininzi kakhulu ichaza ibakala elisemgangathweni ngaphandle kokuqwalasela ukwanda kwe-thermal ngexesha lokutshiswa kweqokobhe okanye ukuba i-nickel-based superalloy iya kusabela njani kwi-slurry yeceramic yasekhaya. Asiyonto yokuthengwa kwempahla. Luthethathethwano phakathi kwekhemistri, inkqubo, kunye nomsebenzi wokugqibela.
Undoqo ongaqondwanga: Ingaphezulu kwePhepha leKhemistri
Makhe sicacise. Umxhasi wake wagxininisa ekusebenziseni ukusebenza okuphezulu I-alloy yokuphosa imali yeprototype yeblade ye turbine, umxube wenickel-chromium yobunini. I-spec sheet ithembisa ukomelela kwesivuno esimangalisayo kwi-800°C. Into engazange ithethe yindlela eyayingaxoleli ngayo ngexesha lokukhupha i-waxing. Sasebenzisa umjikelo we-autoclave oqhelekileyo womphunga. Isiphumo? Iintanda ezincinci kwiqokobhe, phantse zingabonakali, ezibonise kuphela njengeziphene ezingaphezulu emva konyango lokugqibela lobushushu. I-alloyi ibingekho mbi—inkqubo yethu ayizange ilungelelaniswe nokuncipha kwayo kokuqina kunye nokumelana nokothuka kwe-thermal. Nantso ke isifundo: i-alloy data sheet sisahluko sokuqala. Isahluko sesibini sibhalwe kwisiseko sakho.
Apha kulapho amashumi eminyaka yevenkile umgangatho amava trump textbook ulwazi. Iinkampani ezihlala zihleli, njengeQingdao Qiangsenyuan Technology (QSY), azithengisi nje ukuthengisa; bathengisa le nkonzo yokuguqulela. Ungayibona kwindawo yabo kuyo https://www.tsingtaocnc.com. Ngaphezulu kweminyaka engama-30 kwiqokobhe kunye utyalo mali, ixabiso lawo alikho nje ekugaleleni isinyithi; kukwazi ukuba i-alloy esekwe kwi-cobalt yokufakelwa kwezonyango ifuna iqondo lobushushu elahlukileyo laphambi kokungunda kunentsimbi engenasici kwivalve yokulungisa ukutya. Lulwazi oluthe cwaka olo.
Ndikhumbula umsebenzi wepetrochemical component efuna iHastelloy C-276. Ukumelana nokugqwesa okugqwesileyo, iphupha elibi lokuphosa. Isiqulatho sayo se-molybdenum esiphezulu sikwenza ukuba kube lula ukwenza izigaba ze-brittle intermetallic ukuba izinga lokupholisa alilungile nje. Kwafuneka sihlengahlengise iqondo lobushushu elingaphantsi kunomgangatho weklasi ye-alloy kwaye sisebenzise i-toppings exothermic ukulawula isalathiso sokuqina. Isebenzile, kodwa ivele kwibhetshi yokuqala engaphumelelanga apho umbindi wokusasa wawuyingxubakaxaka. I-alloy echanekileyo iphantse yasilela kuba siyiphathe ngokuchanekileyo ngencwadi, kodwa hayi ngokuchanekileyo kwinkqubo yethu yeqokobhe kunye noyilo lokungena.
INtsebenziswano iDynamic: Ukusuka kwiShicilelo ukuya kwiNxalenye
Oku kukhokelela kwinqaku eliphambili lesibini: impumelelo utyalo mali yintsebenziswano, asingomsebenzi wokuthenga. Ukuthumela ushicilelo oluchazwe ngokupheleleyo kwi-Foundry kwaye ucele ucaphulo kukungcakaza. Indlela ekrelekrele ibandakanya iqabane lobugcisa elifana ne-QSY kwangoko. Umnikelo wabo odityanisiweyo wokuphosa kunye nomatshini we-CNC wangaphakathi kuthetha ukuba bacinga ngalo lonke uhambo. Baza kubuza: Ngaba obu bunzima bodonga bufana nokuphepha iindawo ezishushu? okanye singacebisa uyilo oluncinci kweli nqaku ukuze siphucule umgangatho wokusaswa phambi kokuba sichukumise indlela yesixhobo?
Umzekelo, sisebenze kwi-sensor yezindlu kwi-440C engenasici. Inxalenye ibifuna ibhore yangaphakathi ecocekileyo. Umyili ekuqaleni uchaze ibhore ethe tye, njenge-cast-cast. Iqela le-QSY licebise ukuba iphoswe ngaphantsi kancinci kodwa ibe nolwakhiwo oluthandeka ngakumbi, emva koko bayigqibe koomatshini babo be-CNC. Oku ibingengoomatshini bokuthengisa; ibisebenzisa oomatshini ukuqinisekisa ukuba inkqubo yokuphosa inokwenzelwa imfezeko yolwakhiwo, hayi indlela kuphela. Ukuqina kwe-alloy kuye kwanyuswa kunyango lobushushu emva kokuphosa, akuthembekanga ekulungiseni ukuphosa i-porosity.
Enye indlela ngumdlalo wokutyholwa wakudala. I-Foundry igxeka ubumanzi be-alloy, umxhasi ugxeka ubuchule be-Foundry. Ukuba nomthengisi olawula zombini I-alloy yokuphosa imali inguqu kunye nomatshini ochanekileyo phantsi kophahla olunye ulungelelanisa ukuphendula. Xa i-QSY idwelisa umsebenzi wabo ngee-alloys ezikhethekileyo ezifana ne-cobalt kunye ne-nickel-based based, loo nto ibonakalisa ukuba imiselwe le misebenzi edibeneyo, yokusombulula iingxaki, kungekhona nje ukuqhuba iipatheni ze-wax ezilula ngomgca oqhelekileyo.
Ukugada, uKutyisa, kunye neJiyometri efihlakeleyo
Akukho ngxoxo igqityiweyo ngaphandle kwe-gating. I-alloy iyalela inkqubo yokungena ngaphezu kwayo nantoni na. Iialloyi zeAluminiyam? Ngokuqhelekileyo zondla kakuhle, kodwa ziyancipha kakhulu. Udinga izinyusi zesisa. Iintsimbi ezithile ezingenastainless, njengamabakala emartensitic, azinamanzi amdaka. Udinga ukugalelwa okushushu, amaxesha okugcwalisa ngokukhawuleza, kunye namasango abekwe ngononophelo ukunqanda ii-mistruns. Bubuchule obusulungekileyo obu.
Ndafunda oku ngendlela enzima nge-alloy ye-zirconium-copper. Yayiyeyecandelo lombane. I-alloy ine-conductivity emangalisayo kodwa uluhlu oluqinisiweyo oluncinci kakhulu. Isango lethu lokuqala, elisebenze kakuhle kwi-silicon yobhedu, lidale ukucutha okubukhali okuphakathi. Siyisombulule ngokutshintshela kwinkqubo ecinezelekileyo, enetapeed enyanzelise ukuqina komkhombandlela ngaphambili. Uyilo alubukeli nto njengomzekelo wencwadi. Yayimbi, kodwa yayikhupha isandi esivakalayo. Ingongoma kukuba, uyilo lokungena ngumsebenzi othe ngqo wezakhiwo ze-alloy. Awukwazi ukuyikopa-yincamathelise.
Le yenye indawo apho ukusebenza ixesha elide kubonisa ukubaluleka kwayo. Ilayibrari yepateni yenkampani kunye nembali yabo yoyilo lokungena kwiintlobo ezahlukeneyo I-alloy yokuphosa imali iintsapho ziyinto enkulu. Asiyonto onokuyithenga. Iqokelelwe kwiminyaka engama-30 yovavanyo, impazamo, kunye nempumelelo, kufana nje nogcino lwefemu efana ne-QSY ngeyakhiwe. Xa besithi basebenza ngokukhethekileyo kwezi nkqubo, le datha efihliweyo yento esebenze loo ngxubevange yenkohliso ngexesha lokugqibela yinxalenye enkulu yento abayithengisayo.
Umgca wokuGqibela: Xa i-alloy idibana nePost-Processing
Abantu bahlala behlula ukuphosa kunyango lobushushu kunye nomatshini. Yimpazamo enkulu leyo. Ukhetho lwe I-alloy yokuphosa imali umisela imithetho yayo yonke into eza emva kwayo. Thatha i-17-4PH engenasici. Ungayiphosa kwimeko yonyango lwesisombululo (uMqathango A). Kodwa ukuba ufuna i-H1150 eneminyaka ephindwe kabini kukuqina okungcono, kuya kufuneka ucwangcise ulandelelwano lwakho lomatshini. Ukutshiza kwiMeko A kulula, kodwa ke inxalenye iya kuphazamisa ngexesha lokuguga. Ngamanye amaxesha kuya kufuneka umatshini orhabaxa, ubudala, emva koko ugqibezele umatshini. Ukuziphatha kwe-alloy ngumda wexesha.
Sasineprojekthi yecandelo ledrone eMar-M247, i-nickel-based superalloy esekwe. Iphantse yafikeleleka kwimo yayo yokuphathwa bubushushu ngokupheleleyo. Indlela yodwa yayikukuyiphosa ngokusondeleyo kwimilo yomnatha ngokusemandleni omntu, ngoko sebenzisa i-EDM (i-Electrical Discharge Machining) kwiimpawu ezibalulekileyo. Uyilo lonke luqhutywa yinyani yale ngxubevange emva kokuphoswa. I-Foundry kunye nevenkile yomatshini kufuneka ibe nengxoxo rhoqo ukususela kusuku lokuqala. Le ndlela idityanisiweyo yiyo kanye into enikezelwa ngumnikezeli ogxile ngokuthe nkqo. Ukujonga umda we-QSY-i-casting kunye ne-CNC machining-kucacile ukuba le handoff ingaphakathi, ayikho ingozi yomthengisi wangaphandle.
Enye ingongoma efihlakeleyo kukugqiba komphezulu. Ezinye ii-alloys, njenge-aluminiyam-bronzes ezithile, zinokuphuhlisa ukuqina, isikali esiqinileyo emva konyango lobushushu. Ukuba wenza inxalenye yezithambiso, kufuneka uchaze umoya olawulwayo wokuphatha ubushushu okanye isicwangciso sokuchola ngokukrakra. Le asiyiyo yesibini; sisiphumo esithe ngqo sekhemistri yealloyi oyikhethile ekuqaleni. I-alloys ezikhethekileyo ze-QSY zikhankanya ukusebenza nazo ngokungaguquguqukiyo zize nezi mfuno zikhethekileyo zasemva kokulungiswa.
Ukujonga phambili: I-alloy njengendawo yokuQala
Khona oku kusishiya phi? I I-alloy yokuphosa imali lutshintsho olusisiseko. Ayisiyonto yomgca. Yiseti yemiyalelo yawo wonke umbhobho wemveliso. Ubuchwephesha bokwenyani kweli shishini abukho nje ekugaleleni isinyithi, kodwa ekwakheni i-loop impendulo phakathi kwe-metallurgy, i-mold-making, umkhuba wokuthulula, kunye namanyathelo okugqiba.
Ezona projekthi ziphumeleleyo ndibe yinxalenye yokukhethwa kwengxubevange kunye nophuhliso lwenkqubo njengomsebenzi omnye wobunjineli obufanayo. Ibandakanye umyili, i-metallurgist, kunye nenjineli yenkqubo yokuseka ukusuka kwintlanganiso yokuqala yengqiqo. Le modeli yentsebenziswano yinto ejika imathiriyeli ecela umngeni njenge-cobalt-based okanye i-nickel-based. I-alloy yokuphosa imali ukusuka kwityala ukuya kwicandelo elithembekileyo.
Ekugqibeleni, ixesha elide lenkampani kule ndawo, njengerekhodi ye-30 yeminyaka ye-Qingdao Qiangsenyuan Technology, mhlawumbi isalathiso esihle kakhulu sokuqonda okunzulu, okusekelwe kwinkqubo. Ayikokuba nesona sithando somlilo; imalunga nokuba nenkumbulo yeziko yendlela amakhulu eengxubevange ezahlukeneyo aziphathe ngayo kwindawo yawo ethile, ukusuka kwigumbi le-wax ukuya kwindawo yokuthumela inqanawa. Leyo yinto engabonakaliyo eyenza umahluko phakathi kwenxalenye edlula i-QC kunye nenxalenye eyenza ngokungenasiphako kumashumi eminyaka endle.
