Ububanzi bokusebenza nokusebenza kwe-GR5 titanium alloy

I-GR5 titanium alloy yaziwa nangokuthi i-TC4 titanium alloy. Siphinde siyibize nge-6Al4V. Lena insimbi ye-titanium esetshenziswa kakhulu. Ngokuvamile kubizwa ngokuthi i- GR5 titanium ingxubevange sisebenzisa. Inokufinyelela okuhle nokunwetshwa.

I-Titanium nama-alloys ayo anezinto eziningi ezinhle kakhulu ezifana ne-lightweight, amandla aphezulu, ukumelana nokushisa okuqinile, nokumelana nokugqwala. Zaziwa “njengensimbi yesikhathi esizayo” futhi ziyizinto ezintsha zesakhiwo ezinamathemba entuthuko athembisayo. I-Titanium nama-alloys ayo ayinazo izinto ezibaluleke kakhulu kuphela ezimbonini zezindiza kanye ne-aerospace, kodwa futhi isetshenziswe kakhulu emikhakheni eminingi yezimboni njengemboni yamakhemikhali, i-petroleum, imboni ekhanyayo, i-metallurgy, kanye nokuphehla ugesi. I-Titanium ingamelana nokugqwala komzimba womuntu futhi ayiwulimazi umzimba womuntu. Ngakho-ke ingasetshenziswa kabanzi emikhakheni yemboni yezokwelapha neyemithi. I-Titanium inezinto ezinhle zokudonsa futhi isetshenziswa kakhulu kubuchwepheshe be-electronic vacuum kanye nobuchwepheshe be-vacuum ephezulu.

Izakhiwo eziyishumi eziphezulu ze-GR5 titanium alloy

1. Ukuminyana okuphansi namandla athile aphezulu

Ukuminyana kwensimbi ye-titanium ngu-4.51g/cubic centimeter, ephakeme kune-aluminium futhi iphansi kunensimbi, ithusi, ne-nickel, kodwa amandla ayo athile aqala phakathi kwezinsimbi.

I-2. Ukumelana nokugqwala

I-Titanium iyinsimbi esebenza kakhulu enamandla aphansi kakhulu okulingana kanye nokuthambekela okuphezulu kokugqwala kwe-thermodynamic phakathi nendawo. Kodwa empeleni, i-titanium izinzile kakhulu emithonjeni eminingi yezindaba. Isibonelo, i-titanium imelana nokugqwala ku-oxidizing, ingathathi hlangothi futhi inciphisa kancane imidiya. Lokhu kungenxa yokuthi i-titanium inokuhlobana okukhulu nomoya-mpilo. Emoyeni noma emithonjeni yezindaba equkethe umoya-mpilo, kwakheka ifilimu eliminyene, elinamathelayo, ne-inert oxide endaweni ye-titanium, evikela i-titanium matrix ekugqwaleni. Ngisho nangenxa yokugqoka nokukhala kwemishini, izoziphilisa ngokushesha noma ivuselele. Lokhu kukhombisa ukuthi i-titanium iyinsimbi enokuthambekela okunamandla kokudlula. Ifilimu ye-titanium oxide ihlale igcina lesi sici lapho izinga lokushisa eliphakathi nendawo lingaphansi kuka-315°C.

Ukuze kuthuthukiswe ukumelana nokugqwala kwe-titanium, ubuchwepheshe bokwelapha obungaphezulu obufana ne-oxidation, i-electroplating, isifutho se-plasma, i-ion nitridation, ukufakwa kwe-ion, nokucubungula nge-laser senziwe ukuze kuthuthukiswe ukuvikelwa kwefilimu ye-titanium oxide nokuthola ukumelana nokugqwala okufunayo. Umphumela. Ukuphendula isidingo sezinto zensimbi ekukhiqizeni i-sulfuric acid, i-hydrochloric acid, isixazululo se-methylamine, i-chlorine emanzi eshisa kakhulu, kanye ne-chloride eshisa kakhulu, uchungechunge lwama-titanium alloys ukumelana nokugqwala njenge-titanium-molybdenum, i-titanium-palladium. , i-titanium-molybdenum-nickel, njll. Ingxubevange ye-Titanium-32 molybdenum isetshenziselwa ukukhiqiza i-titanium, i-titanium-0.3 molybdenum-0.8 ingxubevange ye-nickel isetshenziselwa izindawo lapho ukugqwala kwe-crevice noma ukugqwala kwe-pitting ngokuvamile kwenzeka, noma i-titanium-0.2 palladium alloy isetshenziselwa izingxenye zemishini ye-titanium, zombili ezinezinsimbi ze-titanium. isetshenziswe kahle. Umphumela.

3. Ukumelana nokushisa okuhle

Ingxubevange entsha ye-titanium ingasetshenziswa isikhathi eside emazingeni okushisa angama-600°C noma ngaphezulu.

4. Ukumelana okuhle kwezinga lokushisa eliphansi

Amandla ama-alloys e-titanium ezinga lokushisa eliphansi amelwe ingxubevange ye-titanium TA7 (Ti-5Al-2.5Sn), TC4 (I-Ti-6Al-4V), futhi i-Ti-2.5Zr-1.5Mo iyanda njengoba izinga lokushisa liyancipha, kodwa i-plasticity ayishintshi. enkulu. Igcina i-ductility enhle nokuqina emazingeni okushisa aphansi -196-253 ° C, igwema ukubola okubandayo kwensimbi. Kuyimpahla efanelekile yeziqukathi ezinezinga lokushisa eliphansi, amabhokisi okugcina, nezinye izinto zokusebenza.

5. Ukusebenza okuqinile kokulwa nokulahla

Ngemuva kokuthi insimbi ye-titanium ingaphansi kokudlidliza komshini kanye nokudlidliza kukagesi, isikhathi sayo sokunciphisa ukudlidliza side kakhulu uma siqhathaniswa nezinsimbi zensimbi nezethusi. Lesi sakhiwo se-titanium singasetshenziswa njengezimfoloko zokulungisa, izingxenye zokudlidliza zama-pulverizer ezokwelapha, namafilimu adlidlizayo ezipikha zomsindo ezisezingeni eliphezulu.

6. Non-magnetic futhi non-toxic

I-Titanium iyinsimbi engeyona enozibuthe futhi ngeke ifakwe uzibuthe endaweni enkulu kazibuthe. Ayinabuthi futhi inokuhambisana okuhle nezicubu negazi lomuntu, ngakho isetshenziswa umphakathi wezokwelapha.

7. Amandla okuqina asondelene namandla okukhiqiza

Lesi sakhiwo se-titanium sibonisa ukuthi isilinganiso samandla esivuno saso (amandla aqinile/amandla esivuno) siphezulu, okubonisa ukuthi izinto zensimbi ye-titanium zine-deformation embi yepulasitiki ngesikhathi sokwakheka. Ngenxa yesilinganiso esikhulu somkhawulo wesivuno se-titanium ku-elastic modulus, i-titanium inokuqina okukhulu ngesikhathi sokubunjwa.

8. Ukusebenza okuhle kokushintshanisa ukushisa

Nakuba i-thermal conductivity yensimbi ye-titanium iphansi kunaleyo ye-carbon steel nethusi, ngenxa yokumelana nokugqwala okuhle kwe-titanium, ukushuba kodonga kungancishiswa kakhulu, futhi indlela yokushintshanisa ukushisa phakathi kobuso nesitimu iwukufingqa okwehlayo, okunciphisa ukushisa. iqembu futhi likha phezulu kakhulu. Akukho ukukala okunganciphisa ukumelana nokushisa, kuthuthukise kakhulu ukusebenza kokudlulisa ukushisa kwe-titanium.

9. I-modulus ephansi yokunwebeka

I-elastic modulus ye-titanium ingu-106.4GPa ekamelweni lokushisa, okungama-57% ensimbi.

10. Ukusebenza kokumunca

I-Titanium iyinsimbi enamakhemikhali asebenza kakhulu futhi ingasabela ngezinto eziningi nezinhlanganisela emazingeni okushisa aphezulu. GR5 titanium ingxubevange ukuphefumula ikakhulukazi kubhekisela ekuphenduleni nge-carbon, i-hydrogen, i-nitrogen, nomoya-mpilo emazingeni okushisa aphezulu.
