Uma uzwa i-'Co 4' ijikijelwa ezingqungqutheleni noma emihlanganweni yokuthengwa kwempahla, ivamise ukuvusa isithombe esithile, kwesinye isikhathi esilula kakhulu: ingxubevange esekwe ku-cobalt yokuguga nokushisa okukhulu. Kodwa lelo lebula lingadukisa uma ungajulile ekucacisweni kwezinto ezibonakalayo. Akulona ibanga elilodwa, lomhlaba wonke elifana ne-304 engenasici; kuyindlela efingqiwe yomndeni, futhi udeveli usekuqanjweni okuningiliziwe—inhlanganisela ethize ye-cobalt, i-chromium, i-tungsten, nekhabhoni enquma ukuthi ingxenye yakho iyasinda yini ekufakweni komugqa wesithando somlilo noma yehluleka ngaphambi kwesikhathi esihlalweni sevalvu enengcindezi ephezulu. Ngibone amaphrojekthi ema ngoba othile ucabange ukuthi wonke ama-Co 4 aziphatha ngendlela efanayo. Ayikwenzi.
Iqiniso Elingemuva Kweshidi Lokucaciswa
Amadokhumenti okuthenga ayalithanda ibhokisi elicocekile: Material: Co 4. Kodwa ukunikeza lokho ku-Foundry noma isitolo semishini kumane kuyisiqalo sengxoxo. Isithiyo sokuqala esisebenzayo ukulandeleka kanye neshidi lokugaya eliqinisekisiwe langempela. Sikhuluma ngama-alloys avame ukusetshenziswa ku-aerospace noma amavalvu esevisi aqinile, ngakho awukwazi ukuvele uthathe igama lomhlinzeki ngakho. Ngikhumbula iqoqo lezingxenye zethuluzi le-downhole lapho ikhemistri ngokobuchwepheshe yayingaphakathi kwebanga elibanzi le-'Co 4', kodwa i-tungsten yayisemkhawulweni ophansi kakhulu. Izingxenye zisebenza kahle, kodwa ukumelana kwazo nokuguga ekuhlolweni kwenkundla kwakucishe kube ngu-15% ngaphansi kwezilinganiso. Ukucaciswa kuhlangatshezwane nakho, kodwa inhloso yohlelo lokusebenza ayizange ifezeke. Lelo igebe phakathi kwamaphepha nokusebenza.
Yilapho ubudlelwano besikhathi eside nabahlinzeki bempahla abaxhumeke phezulu bubalulekile. Inkampani efana I-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), kanye neminyaka yabo engamashumi amathathu ekulingeni nasekukhiqizeni imishini, ngokuvamile inendlela ehluke kakhulu. Ngeke bavele babone u-'Co 4' emdwebeni; inqubo yabo cishe iqala ngokuqinisekisa izinga eliqondile lebanga (ingabe i-ASTM F75, okuhlukile kwe-Stellite, noma inhlanganisela yobunikazi?) bese behlanganisa isikhunta sabo segobolondo noma inqubo yokutshala imali kuyo. Ukuziphatha kokuqina kwalawa ma-alloys kuyakhohlisa-ukuncipha kuyinkinga enkulu. Awukwazi ukuthulula njengensimbi.
Uhlangothi lwemishini lukhulisa lezi zinto ezicashile. Ama-cobalt alloys asebenza kanzima ngokushesha. Uma isu lakho lendlela yamathuluzi lingalungile, awuzinqamuli izinto; uvele uyishaye ibe ungqimba lwangaphezulu oluqinile, oluphukayo oluzobhidliza ukufakwa kwakho okulandelayo kwe-carbide. Ingcindezi epholile kanye nesiqondiso akuxoxiswana ngaso; udinga ukugcina indawo esikiwe ibanda futhi uwashe ama-chips ngokushesha ukuze uvimbele ukushisela kabusha. Kuyisigqi esihlukile uma kuqhathaniswa nensimbi.
Ukusakaza Kwezimali: Lapho Kuhlangana IJiyomethri ne-Alloy
Ezingxenyeni eziyinkimbinkimbi—cabanga ngama-turbine blades noma izingxenye eziyinkimbinkimbi zokujova uphethiloli—ukutshala imali ngokuvamile kuwukuphela kwendlela esebenzayo yama-alloys e-Co 4. Inqubo yephethini ye-wax ivumela lezo ziteshi zangaphakathi nezindonga ezincane ezingenakuqhathaniswa. Kodwa nansi imininingwane evame ukunganakwa: ukwakhiwa kwegobolondo le-ceramic. Ama-alloys e-cobalt anephuzu eliphezulu lokuncibilika futhi angasebenza. Igobolondo elijwayelekile elenzelwe insimbi engagqwali lingase libangele ukungcoliswa komhlaba noma ukuphela okungekuhle. Abahlinzeki abanolwazi olunzulu lwempahla, ongayikala kumaphothifoliyo abo kumasayithi afana nawo https://www.tsingtaocnc.com, izoba nezinhlelo zegobolondo ezizinikele zama-alloys asebenzayo. Kuyimali kanye nokutshalwa kwezimali kolwazi okwehlukanisa ochwepheshe kuma-generalists.
Sizame ukushintshela ku-caster entsha yokutshala imali enezindleko eziphansi kwamanye amapuleti okugqoka amaphampu. Imidwebo ibibiza i-Co 4. Amasampula abukeka ekahle ngokubukeka. Kodwa ngesikhathi sokuhlolwa kokuqala kodaka lwengcindezi ephezulu, imifantu emincane yasakazwa kulokho okwaba yi-ceramic inclusions esikhunjeni segobolondo esihlanganiswe ne-alloy surface. Ukuhlaziywa kokwehluleka kukhomba kusistimu yokuhlanganisa igobolondo. Kwadingeka silahle yonke inqwaba futhi siphinde sithole umthombo. Izindleko zokwehluleka zincane kakhulu noma yikuphi ukonga kokuqala. Isifundo sasiwukuthi ngalezi zinsiza, inqubo ye-Foundry ibaluleke kakhulu njengethikithi le-alloy.
Ngemuva kokusakazwa, ukwelashwa kokushisa kungenye indawo yemigodi. Ukunciphisa ingcindezi kuhlale kudingekile, kodwa imijikelezo yokwelapha nokuguga yama-cobalt alloys izwela ngendlela emangalisayo. Isikhathi esiningi kakhulu noma amadigri ambalwa aphezulu kakhulu, futhi ungakwazi ukuletha izigaba eziphukayo ezibulala ukuqina. Akuyona isethi futhi ukhohlwe umjikelezo kahhavini. Udinga ukulawulwa kwesithando somlilo okunembile futhi ngokuvamile, ukhiphe umoya noma umoya olawulwayo ukuze uvimbele ukuwohloka kwendawo. Ukukhuluma kwe-QSY ngokusebenza ngama-alloys akhethekile kuphakamisa ukuthi bakuzulile lokhu; akulona ikhono olithuthukisa ngobusuku obubodwa.
I-CNC Machining: Ubuciko Bokususa Izinto Ezinzima Kakhulu
Yilapho ulwazi lwetiyetha luhlangana khona nokukhala kwentolo. Izingxenye ze-Machining cast Co 4 kuya kubukhulu bokugcina yilapho amamajini enzuzo angasulwa khona. Ukugqokwa kwamathuluzi kuyachayeka. Salinganisa amabanga athile e-sub-micron grain carbide, kwesinye isikhathi sithuthela ku-ceramic noma ku-CBN (cubic boron nitride) ukuze siqedele amaphasi. Kodwa noma kunjalo, impilo yamathuluzi ikalwa ngemizuzu, hhayi amahora. Ukusebenza ngempumelelo kuncike ekubambeni amathuluzi aqinile (akukho ukuphuma okuvunyelwe), ithuluzi lomshini oqinile, kanye nokuphakelayo okulungiselelwe ngokuphelele nesivinini.
Ithiphu elisebenzayo silifunde kabuhlungu: ungalokothi uphazamise ukusikeka. Uma umisa okwesikhashana noma wenza ukusika okuphazanyiswe yidizayini, umeme ukwehluleka kwethuluzi okuyinhlekelele. Isu liwukusebenzisa izindlela zokugaya i-trochoidal ukuze kugcinwe ukusebenzisana kwamathuluzi njalo nokulawula ukushisa. Ihamba kancane ezinhlelweni kodwa iyashesha ngesikhathi somshini wangempela ngoba awushintshi okufakwayo kuzo zonke ezinye izingxenye.
Ngaphezu kwalokho, i- CNC imishini kulawa ma-alloys akhiqiza ama-chips anezintambo, abukhali ashisa ngokubomvu. Ukuphathwa kwe-chip kuyinkinga yokuphepha nekhwalithi. Bekufanele sibuyisele kabusha amasistimu wokupholisa anomfutho ophezulu ikakhulukazi ukuze le misebenzi iphule futhi ikhiphe ama-chips. Isitezi sesitolo somjaho we-Co 4 sibukeka sihlukile—sinomsindo omkhulu, sishisa kakhulu, futhi kuba nokushuba okuphathekayo kuze kuphume ingxenye yokuqala enhle.
Ukutholakala kwezinto ezibonakalayo kanye nelensi ye-Supply Chain
Uvelaphi ingxubevange ye-Co 4 eluhlaza? Lona umbuzo we-geopolitical and logistical of much njengowobuchwepheshe. I-Cobalt iyinto yamasu. I-supply chain yayo inokuguquguquka. Uzakwethu onokwethenjelwa akagcini ngomshini izinto; bayakusiza ukuthi uyivikele. Bakhe ubudlelwano nabakhiqizi be-alloy abakhulu noma bangaluleka ngamanye amamaki amukelekayo phakathi komndeni we-Co 4 angase abe nokutholakala okungcono ngaphandle kokuphazamisa umsebenzi oyinhloko.
Ngesikhathi sokuphazamiseka kwe-supply chain eminyakeni embalwa edlule, saba nephrojekthi ye-prototypes yokufakelwa kwezokwelapha eyacacisa ingxubevange ye-CoCr yezinga elithile lokuhlinzwa. Isikhathi sokuhola esigayweni sokuqala sasingamaviki angama-40. Umhlinzeki onekhono odidiyelwe uphakamise ukushintshela esitokweni sezinga elifanayo ababesinikeze isitifiketi somsebenzi we-aerospace wangaphambilini, nokulungiswa kancane kokwelashwa kokushisa kwangemuva kokusakazwa ukuze kufane nezakhiwo zomshini ezidingekayo. Igcine iphrojekthi. Lolo hlobo lokuxazulula izinkinga luvela kokuhlangenwe nakho, hhayi nje imanuwali yesitolo semishini.
Leli inani lemodeli yesevisi yokuma okukodwa kwezingxenye ezibalulekile. Lapho uphonsa, ukwelashwa kokushisa, futhi CNC imishini zingaphansi kophahla olulodwa, njengomhlinzeki ohlanganisiwe, izihibe zempendulo ziqinile. Ochwepheshe bemishini bangatshela ithimba labasunguli uma iqoqo elithile liyi-gummy noma libangela ukuguga okungajwayelekile kwamathuluzi, okungahle kulandelele ukuchezuka okuncane kukhemistri yokuncibilika noma izinga lokupholisa. Leyo ngxoxo yangaphakathi ayinakwenzeka uma ulima isinyathelo ngasinye kubathengisi abahlukene.
Imicabango Ephethayo: Kuyinqubo, Hhayi Ukuthenga Nje
Ngakho-ke, lapho usebenzisana ne-Co 4, awuthengi ngempela impahla. Uthenga ikhono lokukhiqiza elididiyelwe ngokujulile. Igama elingukhiye liyiphoyinti lokungena nje. Izindleko zangempela nempumelelo kunqunywa yikho konke okwenzekayo ngemva kokusikwa kwe-PO: umkhuba wokuncibilika, ukwakheka kwesikhunta, imijikelezo yokushisa, nesu lomshini.
Uma ngibheka iphrofayili yenkampani efana ne-QSY's—iminyaka engama-30 yokulingisa nokwenza imishini, ibiza ama-alloys asekelwe ku-cobalt ngokuqondile-okungitshela ukuthi kungenzeka bakhe ulwazi lwesikhungo mayelana nalezi zinselele. Iwebhusayithi yabo, https://www.tsingtaocnc.com, akuyona nje ingosi yokuthengisa; kumthengi wezobuchwepheshe, kuwuphawu lwezindawo zabo ezikhethekile ezishiwo. Usazohlola amakhono abo, kodwa kunciphisa inkundla kusukela ezitolo zemishini evamile kuye kulabo okungenzeka baqonde ukuthi kungani ingxenye yakho ye-Co 4 ingakwazi ukuphathwa njengebhulokhi yensimbi ethambile.
Ekugcineni, impumelelo ngalawa ma-alloys imayelana nokuhlonipha ubunkimbinkimbi bawo. Ukubambisana phakathi komklami oqonda indawo yesevisi, i-metallurgist ecacisa ibanga eliqondile, kanye nozakwethu wokukhiqiza onezibazi nezisombululo zokukwenza ngaphambili. Igama elithi 'Co 4' liyisiqalo nje saleyo ngxoxo.
