Ingxubevange ye-Titanium kunzima ukucubungula indlela yokukhetha ithuluzi le-alloy material, i-titanium alloy cutting process ukukhethwa kwezici ze-Shuo ukunemba kwezinto ezibonakalayo embonini yokukhiqiza, ngokuvamile zihlangana nokucubungula izinto ze-titanium alloy, futhi ngenxa yezici ze-titanium kunzima kakhulu ukucubungula;Uma kuqhathaniswa nezinsimbi ezivamile, ingxubevange ye-titanium inamandla angcono, ukuqina, i-ductility, nokumelana okungcono ne-oxidation kanye nokumelana nokugqwala.Lokhu kwenza ama-titanium alloys asetshenziswe kabanzi ku-aerospace, izimoto, amakhemikhali kanye nemishini yezokwelapha nakweminye imikhakha.Ukufakwa kwamathuluzi okucutshungulwa kwe-titanium alloy nakho kudlala indima enhle kumathuluzi wokusika, ukugqoka okuhle kungathuthukisa ukumelana nokugqokwa kwethuluzi, kuthuthukise ubulukhuni balo bokushisa okuphezulu, ukusebenza kokufakwa kokushisa, ukuzinza kokushisa, ukuqina komthelela, njll., ukuze kuthuthukiswe kakhulu thuthukisa isivinini sokusika kanye nempilo yesevisi yethuluzi.I-Titanium alloy in toughness, ductility, ikakhulukazi amandla ingaphezulu kakhulu kunezinye izinto zensimbi, ingakhiqiza amandla aphezulu eyunithi, ukuqina okuhle, izingxenye zomkhiqizo wesisindo esincane.Eminyakeni yamuva nje, ingxubevange ye-titanium iye yasetshenziswa kabanzi endizeni ukuze ithathe indawo ye-aluminium ingxubevange, isizathu siwukuthi ingxubevange ye-titanium inokuqina okuhle kokushisa, amandla okushisa aphezulu, ku-300-500 ° C, amandla ayo aphindwe izikhathi ezingu-10 kune-aluminium alloy, futhi izinga lokushisa lokusebenza lingafinyelela ku-500 ° C. Inokumelana nokugqwala okuphezulu kwe-alkali, i-chloride, i-chlorine izinto eziphilayo, i-nitric acid, i-sulfuric acid, njll. Ngesikhathi esifanayo, i-titanium alloy endaweni enomswakama kanye nendawo yamanzi olwandle, ukumelana i-pitting, ukugqwala kwe-asidi, ukugqwala kwengcindezi kudlula kude lokho kwensimbi engagqwali.Imikhiqizo eyenziwe nge-titanium alloy nayo inokuqina okuphezulu, indawo ephezulu yokuncibilika, engeyona enobuthi, engeyona i-magnetic nezinye izici.Ngokusekelwe ochungechungeni olungenhla lwezakhiwo ezinhle kakhulu, ama-titanium alloys asetshenziswa okokuqala endizeni.Ngo-1953, i-United States Douglas Company okokuqala ngqa yasebenzisa izinto ze-titanium kuma-pods enjini ye-DC2T nezindonga zomlilo, futhi yazuza imiphumela emihle.Emkhakheni we-aerospace, ifeni, i-compressor, isikhumba, i-fuselage kanye negiya lokuhlala lenjini yendiza zingabokuqala ukusebenzisa i-titanium alloy njengento ebalulekile, okwenza isisindo sendiza sinciphe cishe ngo-30% -35%, kanye ne-titanium. Ingxubevange iphinde yasetshenziswa ngempumelelo ekwakhekeni kwengcindezi yemikhumbi-ngwenya yenuzi, amapayipi amapayipi amanzi olwandle, ama-condenser nama-heaters, ama-fan blade, ama-thruster namashafti, iziphethu, nokuvikelwa komlilo ezithwala izindiza Imishini, uphephela, idivayisi yokushayela indiza yamanzi, iphini kanye ezinye izingxenye Zasolwandle.Ngaphezu kwalokho, ngenxa ye-biocompatibility yayo enhle, ukumelana nokugqwala, izakhiwo zemishini kanye nezakhiwo zokucubungula, ingxubevange ye-titanium isiphenduke into efanelekile yensimbi yezinto eziphilayo, esetshenziswa ngempumelelo emalungeni okwenziwa amadolo, amalunga ezinsikazi, izimila zamazinyo, izimpande zamazinyo nezisekelo zensimbi yokufakelwa, njll. Phakathi kwazo, i-Ti6AI4V ivame ukusetshenziswa njengento yokufakelwa kwezokwelapha, futhi i-TI3AI-2.5V ingxubevange iphinde isetshenziswe njengengxenye yempahla ye-femur ne-tibia emisebenzini yomtholampilo ngenxa yokubukeka kwayo okuhle okubandayo, ukumelana nokugqwala kanye nezakhiwo zemishini.
Ubunzima bokucutshungulwa kwe-titanium alloy (1) i-deformation coefficient incane, okuyisici esisobala kakhulu ekusikeni kwe-titanium alloy materials.Enqubweni yokusika, indawo yokuxhumana phakathi kwe-chip nendawo yethuluzi langaphambili inkulu kakhulu, ukuhamba kwe-chip endaweni yamathuluzi yangaphambili inkulu kakhulu kune-chip yempahla evamile, ngokuhamba kwesikhathi eside kangaka kuzoholela ethuluzini elibucayi. gqoka, futhi ukungqubuzana phakathi nenqubo yokuhamba kuzobangela izinga lokushisa lethuluzi likhuphuke.(2) Izinga lokushisa lokusika liphezulu, ngakolunye uhlangothi, i-deformation coefficient okukhulunywe ngayo ngaphambili izoholela engxenyeni yokwanda kwezinga lokushisa.Isici esiyinhloko sokushisa okuphezulu kokusika enqubweni yokusika i-titanium alloy kungenxa yokuthi ukuqhutshwa kokushisa kwe-titanium alloy kuncane kakhulu, futhi ubude bokuxhumana phakathi kwe-chip nendawo yamathuluzi yangaphambili bufushane, ngaphansi kwethonya lalezi zici, ukushisa okukhiqizwa phakathi nenqubo yokusika kunzima ukuyikhipha, ikakhulukazi kugcinwa eduze kwesihloko sethuluzi, okwenza izinga lokushisa lendawo libe phezulu kakhulu.(3) Ukudlidliza, ekuqedeni inqubo, i-modulus ephansi enwebekayo ye-titanium alloy kanye namandla okusika ashukumisayo yizona zimbangela eziyinhloko zokudlidliza enqubweni yokusika.(4) I-thermal conductivity ye-titanium alloy iphansi kakhulu, futhi ukushisa okukhiqizwa ngokusika akulula ukukuhlakaza.Inqubo yokuguqula i-titanium alloy iyinqubo yokucindezeleka okukhulu nokucindezeleka, okuzokhiqiza ukushisa okukhulu, futhi ukushisa okuphezulu okukhiqizwa ngesikhathi sokucubungula akukwazi ukusabalalisa ngokuphumelelayo, kuyilapho ubude bokuxhumana bomkhawulo wokusika wethuluzi kanye ne-chip. kufushane, ukuze inani elikhulu lokushisa liqoqwe onqenqemeni lokusika, izinga lokushisa likhuphuke kakhulu, i-blade iyancipha, futhi ukugqoka kwamathuluzi kuyashesha.(5) Umphumela wamakhemikhali we-titanium alloy mkhulu, futhi emazingeni okushisa aphezulu, ingxubevange ye-titanium kulula ukusabela ngayo ngezinto zamathuluzi ukusheshisa ukwakheka kwe-crescent.Kodwa-ke, inqubo yokusika ye-titanium alloys yenziwa ngokuyisisekelo emazingeni okushisa aphezulu.Uma izinga lokushisa lokusika liphezulu ngezinga elithile, ama-molecule afana ne-nitrogen nomoya-mpilo emoyeni angasebenzisana kalula ngamakhemikhali nezinto ze-titanium, okuholela ekwakhekeni kwesikhumba esiqinile esiphukayo.Ngaphezu kwalokho, i-deformation yepulasitiki yendawo eyenziwe ngomshini we-workpiece enqubweni yokusika ye-titanium material iholela ekuveleni kwento ebandayo eqinile, futhi into eqinile yenzeka endaweni emshinini wezinto zokusebenza.Lezi zenzakalo zingandisa ukuguga kwethuluzi futhi zinciphise amandla okukhathala kwempahla ye-titanium.(6) Ithuluzi kulula kakhulu ukuligqoka, ukuguga kwethuluzi kuwumphumela wezinto eziningi ezibanzi ndawonye, enqubweni yokusika ye-titanium alloy material, Kulula ukubangela ukuphulwa kwethuluzi, izinto ze-titanium ngokuvamile zibonisa ukuhlangana kwamakhemikhali okuqinile phakathi kwezinto zamathuluzi ngaphansi kwezimo eziphakeme zokushisa, futhi ithuluzi kanye ne-titanium alloy material kulula ukubopha ekushiseni okuphezulu, okuholela empilweni yesevisi yethuluzi kufushane kakhulu.Ngakho-ke, ukusika kwe-titanium alloy materials kumele kunake izici ezimbili, okungukuthi, ukugcina izinga lokushisa eliphansi lokusika futhi uthuthukise ukuqina kwethuluzi noma izinto ezisikwayo, futhi ithuluzi lokumboza liyindlela yokuthuthukisa ukuqina kwensimbi. ithuluzi.Ngenxa yomsebenzi wamakhemikhali aphezulu kanye nokushisa okuphansi kwe-titanium alloy, izinga lokushisa lokusika liphezulu enqubweni yokusika, ukusabela kwamakhemikhali kunamandla, ithuluzi lihluleka ngokushesha, okuholela ekuphileni kwamathuluzi okufushane kanye nezindleko eziphezulu zokucubungula.Izimbangela zokugqoka kwamathuluzi zihlanganisa ukungqubuzana kwemishini kanye nokusabela ngokomzimba namakhemikhali ngaphansi kwesenzo sokusika amandla kanye nezinga lokushisa lokusika.Ngenxa yobunzima bomshini we-titanium alloy machining, izinto ezikhethiwe zamathuluzi kufanele zihlangabezane nezidingo zokuqina okuphezulu, amandla aphezulu, ukuqhutshwa kokushisa okuphezulu, ukuzinza kwamakhemikhali kanye nobunzima obuhle obomvu.Ukuhlolwa kwemboni kukhombisa ukuthi umphumela wokucubungula we-titanium alloy uyithuluzi elingcono ledayimane le-PCD, kepha ngenxa yentengo yalo ephezulu, likhawulela ububanzi obuningi bokucubungula, futhi ukwenza kahle imingcele yenqubo kungenza ukusika kwe-titanium alloy materials kube ngcono izinga elithile, kodwa ububanzi abukhulu;Uketshezi olunqamula umfutho ophezulu, ukusika izinga lokushisa eliphansi kanye nepayipi lokushisa lokudlulisa ukushisa izindlela zokuthambisa zokuthambisa ziyafundwa ngale ndlela
