Ii-alloys ze-Titanium zineempawu ezibalaseleyo zoomatshini kodwa iipropathi zenkqubo ezimbi, ezikhokelela ekuphikiseni ukuba amathuba ezicelo zabo athembisayo kodwa ukucubungula kunzima. Kweli phepha, ngokuhlalutya ukusebenza kwesinyithi sokusika i-titanium alloy materials, kudityaniswe neminyaka emininzi yamava omsebenzi osebenzayo, ukukhethwa kwezixhobo zokusika i-titanium alloy, ukuzimisela kwesantya sokusika, iimpawu zeendlela zokusika ezahlukeneyo, izibonelelo zomatshini kunye neendlela zokukhusela. kuyaxoxwa. Icacisa iimbono zam kunye neengcebiso malunga nokwenziwa kwe-titanium alloys.
I-alloy ye-Titanium inoxinano oluphantsi, amandla athile aphezulu (amandla / ubuninzi), ukuxhathisa okulungileyo kwe-corrosion, ukumelana nobushushu obuphezulu, ukuqina okulungileyo, iplastiki kunye ne-weldability. Iingxube ze-Titanium zisetyenziswe ngokubanzi kwiindawo ezininzi. Nangona kunjalo, ukungahambi kakuhle kwe-thermal, ukuqina okuphezulu, kunye ne-elastic modulus ephantsi kwenza i-titanium alloys ibe yintsimbi enzima ukuyiqhuba. Eli nqaku lishwankathela amanyathelo athile ethekhnoloji kwi-machining ye-titanium alloys ngokusekelwe kwiimpawu zayo zobuchwepheshe.
Iinzuzo eziphambili ze-titanium alloy materials
(1) I-Titanium alloy inamandla amakhulu, ubuninzi obuphantsi (4.4kg / dm3) kunye nobunzima obulula, obunika isisombululo sokunciphisa ubunzima bezinye iindawo ezinkulu zesakhiwo.
(2) Amandla aphezulu ashushu. I-alloys ye-Titanium inokugcina amandla aphezulu phantsi kwemeko ye-400-500 ℃ kwaye inokusebenza ngokuzinzileyo, ngelixa ubushushu bokusebenza be-aluminium alloys bunokuba ngaphantsi kwe-200 ℃.
(3) Xa kuthelekiswa nentsimbi, ukuxhathisa kwe-corrosion ephezulu ye-titanium alloy kunokonga iindleko zokusebenza kwemihla ngemihla kunye nokugcinwa kwenqwelomoya.
Uhlalutyo lweempawu zomatshini we-titanium alloy
(1) Ukuhanjiswa kwe-thermal ephantsi. I-thermal conductivity ye-TC4 kwi-200 ° C yi-l = 16.8W / m, kunye ne-thermal conductivity yi-0.036 cal / cm, eyi-1/4 kuphela yensimbi, i-1/13 ye-aluminium kunye ne-1/25 yobhedu. Kwinkqubo yokusika, ukutshatyalaliswa kobushushu kunye nefuthe lokupholisa lihlwempu, elinciphisa ubomi besixhobo.
(2) Imodyuli elastiki iphantsi, kwaye umphezulu owenziwe ngoomatshini wenxalenye unomda omkhulu wokuphinda ubuyele, nto leyo ekhokelela ekwandeni kwendawo yokunxibelelana phakathi komphezulu owenziwe ngoomatshini kunye necala lecala lesixhobo, elingachaphazeli kuphela ukuchaneka komgangatho wesixhobo. inxalenye, kodwa kunciphisa ukuqina kwesixhobo.
(3) Ukusebenza kokhuseleko ngexesha lokusika kubi. I-Titanium sisinyithi esinokutsha, kwaye ubushushu obuphezulu kunye neentlantsi ezenziwe ngexesha lokusika kancinci kunokubangela ukuba iitshiphusi zetitanium zitshise.
(4) Ubunzima. I-alloys ye-Titanium enexabiso eliphantsi lobulukhuni iya kuba yinto encamathelayo xa i-machining, kwaye iitshiphusi ziya kunamathela kumda wokusika we-rake yesixhobo sokwenza i-edge edge, echaphazela i-machining effect; iialloyi ze-titanium ezinexabiso eliphezulu lobulukhuni zithande ukutshiphuzwa kunye nokutyhutyha isixhobo ngexesha lomatshini. Ezi mpawu zikhokelela kwizinga eliphantsi lokususa isinyithi se-titanium alloy, eyi-1/4 kuphela yentsimbi, kwaye ixesha lokucubungula lide kakhulu kunelo lentsimbi yobukhulu obufanayo.
(5) Ubudlelwane obuqinileyo bekhemikhali. I-Titanium ayinakusabela kuphela ngokwemichiza kunye namacandelo aphambili e-nitrogen, ioksijini, i-carbon monoxide kunye nezinye izinto ezisemoyeni ukwenza umaleko oqinileyo we-TiC kunye ne-TiN kumphezulu we-alloy, kodwa uphinde uphendule ngesixhobo sesixhobo phantsi kobushushu obuphezulu. iimeko eziveliswa yinkqubo yokusika, ukunciphisa isixhobo sokusika. yokuqina.
