I-alloy ye-Titanium inzima ukucwangcisa indlela yokukhetha izixhobo ze-alloy, i-titanium alloy cutting process yokukhethwa kweempawu ze-Shuo ezichanekileyo zesixhobo kwi-shishini lokuvelisa, zihlala zidibana nokucubungula izinto ze-titanium alloy, kwaye ngenxa yeempawu ze-titanium kunzima kakhulu ukuyiqhuba;Xa kuthelekiswa nesinyithi esiqhelekileyo, iialloyi ze-titanium zinamandla angcono, ukuqina, i-ductility, kunye nokuxhathisa okungcono kwe-oxidation kunye nokuxhathisa ukubola.Oku kwenza i-titanium alloys isetyenziswe ngokubanzi kwi-aerospace, i-automotive, i-chemicals kunye nezixhobo zonyango kunye nezinye iindawo.Ukugqunywa kwezixhobo ze-titanium alloy kudlala indima entle kwizixhobo zokusika, ukugquma okulungileyo kunokuphucula ukuxhathisa kwesixhobo, ukuphucula ukuqina kwayo kobushushu obuphezulu, ukusebenza kobushushu bokushisa, ukuzinza kwe-thermal, ukuqina kwempembelelo, njl., ukwenzela ukuba kakhulu ukuphucula isantya sokusika kunye nobomi benkonzo yesixhobo.Ingxubevange ye-Titanium kukuqina, i-ductility, ngakumbi amandla angaphezulu kunezinye izinto zetsimbi, inokuvelisa amandla aphezulu eyunithi, ukuqina okuhle, iinxalenye zemveliso yobunzima bokukhanya.Kwiminyaka yakutshanje, ingxubevange ye-titanium isetyenziswe ngokubanzi kwinqwelo-moya ukuze ithathe indawo yealluminiyam, isizathu kukuba ialloyi ye-titanium inozinzo oluhle lwe-thermal, amandla okushisa aphezulu, kwi-300-500 ° C, amandla ayo aphindwe ka-10 ngaphezu kwe-aluminium alloy, kunye nobushushu bokusebenza bunokufikelela kwi-500 ° C. Inokumelana nokugqwesa okuphezulu kwi-alkali, i-chloride, i-chlorine yezinto eziphilayo, i-nitric acid, i-asidi ye-sulfuric, njl. Ngelo xesha, i-titanium alloy kwindawo efumileyo kunye ne-medium yamanzi olwandle, ukuxhathisa i-pitting, i-acid corrosion, i-corrosion yoxinzelelo idlula lee insimbi engenasici.Iimveliso ezenziwe nge-titanium alloy nazo zinobunzima obuphezulu, indawo yokunyibilika ephezulu, i-non-toxic, non-magnetic kunye nezinye iimpawu.Ngokusekwe kolu luhlu lungasentla lweepropathi ezigqwesileyo, iialloyi ze-titanium zisetyenziswa okokuqala kwinqwelomoya.Ngo-1953, iNkampani yase-United States iDouglas okokuqala ngqa yasebenzisa imathiriyeli ye-titanium kwi-injini yeenjini ze-DC2T kunye neendonga zomlilo, kwaye yafumana iziphumo ezilungileyo.Kwintsimi ye-aerospace, i-fan, i-compressor, isikhumba, i-fuselage kunye ne-landing gear ye-injini ye-aviation yeyokuqala ukusebenzisa i-titanium alloy njengento ebalulekileyo, okwenza ubunzima benqwelo-moya buncitshiswe malunga ne-30% -35%, kunye ne-titanium. I-alloy iye yasetyenziswa ngempumelelo kwizindlu zoxinzelelo zeenkwili zenyukliya, iinkqubo zemibhobho yamanzi olwandle, iicondenser kunye nezitshintshisi zobushushu, ii-fan blades, ii-thrusters kunye neeshafti, imithombo, kunye nokukhuselwa komlilo kwizinto ezithwala inqwelo-moya Izixhobo, ipropeller, isixhobo sokuqhuba ijethi yamanzi, irudder kunye amanye amacandelo oLwandle.Ukongeza, ngenxa ye-biocompatibility yayo elungileyo, ukumelana nokugqwala, iipropathi zoomatshini kunye neepropathi zokusetyenzwa, i-titanium alloy iye yaba yeyona nto ifanelekileyo yezixhobo zetsimbi yebhayomedical, isetyenziswe ngempumelelo kwiindawo zokuhlangana kwamadolo, amalungu e-femoral, ukufakelwa kwamazinyo, iingcambu zamazinyo kunye nezixhaso zetsimbi yamazinyo, njl. Phakathi kwabo, i-Ti6AI4V isetyenziswa ngokuqhelekileyo njengento yokufakelwa kwezonyango, kwaye i-TI3AI-2.5V ingxubevange iphinda isetyenziswe njengesixhobo sokutshintsha i-femur kunye ne-tibia kwimisebenzi yeklinikhi ngenxa yokubanda kwayo kakuhle, ukuxhathisa ukubola kunye neempawu zomatshini.
Ubunzima be-titanium alloy processing (1) i-coefficient ye-deformation incinci, into ebonakalayo ebonakalayo ekusikeni kwe-titanium alloy materials.Kwinkqubo yokusika, indawo yoqhagamshelwano phakathi kwetshiphu kunye nomphezulu wesixhobo sangaphambili mkhulu kakhulu, ukuhamba kwetshiphu kumphezulu wesixhobo esingaphambili mkhulu kakhulu kunesixhobo se-chip ngokubanzi, ekuhambeni kwexesha elide kuya kukhokelela kwisixhobo esinzulu. ukugqoka, kunye ne-friction ngexesha lenkqubo yokuhamba kuya kubangela ukuba ukushisa kwesixhobo kunyuke.(2) Iqondo lokushisa lokusika liphezulu, kwelinye icala, i-coefficient deformation ekhankanywe ngaphambili iya kukhokelela kwinxalenye yokunyuka kweqondo lokushisa.Inkalo ephambili yobushushu obuphezulu bokusika kwinkqubo yokusika i-titanium alloy kukuba i-thermal conductivity ye-titanium alloy incinci kakhulu, kwaye ubude boqhagamshelwano phakathi kwe-chip kunye nesixhobo sangaphambili sifutshane, phantsi kweempembelelo zezi zinto. ukushisa okwenziwa ngexesha lenkqubo yokusika kunzima ukuqhuba ngaphandle, ngokukodwa kugcinwe kufuphi nencam yesixhobo, kubangela ukuba ukushisa kwendawo kuphezulu kakhulu.(3) I-Vibration, kwinkqubo yokugqiba, i-modulus ephantsi ye-elastic ye-titanium alloy kunye ne-dynamic cutting force yizona zizathu eziphambili zokunyakaza kwinkqubo yokusika.(4) I-thermal conductivity ye-titanium alloy iphantsi kakhulu, kwaye ukushisa okwenziwa ngokusika akulula ukusabalalisa.Inkqubo yokuguqula i-titanium alloy yinkqubo yoxinzelelo olukhulu kunye noxinzelelo, oluya kuvelisa ubushushu obuninzi, kwaye ubushushu obuphezulu obuveliswa ngexesha lokucubungula alukwazi ukusasazwa ngokufanelekileyo, ngelixa ubude boqhagamshelwano lomphetho wokusika isixhobo kunye ne-chip. mfutshane, ukwenzela ukuba ubushushu obukhulu buqokelelwe kwi-cut cut, iqondo lokushisa likhuphuka ngokukhawuleza, i-blade iyancipha, kwaye isixhobo sokugqoka sikhawuleza.(5) Impembelelo yeekhemikhali ye-titanium alloy inkulu, kwaye kumaqondo okushisa aphezulu, i-titanium alloy kulula ukusabela ngayo kunye nesixhobo sokukhawulezisa ukubunjwa kwe-crescent.Nangona kunjalo, inkqubo yokusika i-titanium alloys iqhutyelwa ngokusemgangathweni kumaqondo aphezulu.Xa iqondo lokushisa lokusika liphezulu ukuya kwinqanaba elithile, iimolekyuli ezifana ne-nitrogen kunye ne-oksijini emoyeni zinokusebenzisana ngokulula kweekhemikhali kunye nezixhobo ze-titanium, okukhokelela ekubunjweni kwesikhumba esilukhuni.Ukongeza, i-deformation yeplastiki yomgangatho owenziwe ngomatshini womsebenzi kwinkqubo yokusika izinto ze-titanium ikhokelela ekubeni kwenzeke into ebandayo enzima, kwaye into enzima iyenzeka kumphezulu womatshini wezinto zokusebenza.Ezi ziganeko zinokunyusa ukunxiba kwesixhobo kunye nokunciphisa amandla okudinwa kwezinto ze-titanium.(6) Isixhobo silula kakhulu ukunxiba, ukunxitywa kwesixhobo sisiphumo sezinto ezininzi ezibanzi kunye, kwinkqubo yokusika i-titanium alloy material, Kulula ukubangela ukuphulwa kwesixhobo, izixhobo ze-titanium zibonisa ngokubanzi a unxulumano olomeleleyo lwekhemikhali phakathi kwezixhobo zesixhobo phantsi kweemeko eziphezulu zobushushu, kunye nesixhobo kunye ne-titanium alloy material kulula ukudibanisa kwiqondo lokushisa eliphezulu, elikhokelela kubomi benkonzo yesixhobo mfutshane kakhulu.Ngoko ke, ukusika izinto ze-titanium alloy kufuneka zihlawule ingqalelo kwiinkalo ezimbini, oko kukuthi, ukugcina ubushushu obuphantsi bokusika kunye nokuphucula ukuqina kwesixhobo okanye izinto ezisikwayo, kunye nesixhobo sokugquma yindlela yokuphucula ukuqina kwesixhobo. isixhobo.Ngenxa yokusebenza kweekhemikhali eziphakamileyo kunye ne-thermal conductivity ye-titanium alloy, ukushisa kweqondo lokushisa kuphezulu kwinkqubo yokusika, ukusabela kweekhemikhali kunamandla, isixhobo sihluleka ngokukhawuleza, okubangelwa ubomi obufutshane besixhobo kunye neendleko eziphezulu zokusebenza.Izizathu zokugqoka izixhobo zibandakanya ukungqubuzana komatshini kunye neempendulo zomzimba kunye neekhemikhali phantsi kwesenzo sokusika amandla kunye nokushisa kokusika.Ngenxa yobunzima be-titanium alloy machining, izixhobo ezikhethiweyo zesixhobo kufuneka zihlangabezane neemfuno zobunzima obuphezulu, amandla aphezulu, ukuhanjiswa kwe-thermal ephezulu, ukuzinza kweekhemikhali kunye nobunzima obuhle obomvu.Uvavanyo loshishino lubonisa ukuba isiphumo sokucutshungulwa kwe-titanium alloy sisixhobo sedayimani esingcono se-PCD, kodwa ngenxa yexabiso layo eliphezulu, inciphisa uluhlu olubanzi lokusetyenzwa, kunye nokuphucula iiparameters zenkqubo kunokwenza ukusika kwezixhobo ze-titanium alloy kuphuculwe. ubungakanani obuthile, kodwa uluhlu alukhulu;Uxinzelelo oluphezulu lokusika ulwelo, ukusika ubushushu obuphantsi kunye nombhobho wobushushu wokudlulisa ubushushu iindlela zokuthambisa zokupholisa ziyafundwa kweli cala
