Titanium alloys ane yakanakisa mechaniki zvivakwa asi yakashata maitiro zvimiro, izvo zvinotungamira kune kupokana kuti tarisiro yavo yekushandisa iri kuvimbisa asi kugadzirisa kwakaoma.Mupepa rino, nekuongorora simbi yekucheka mashandiro etitanium alloy zvinhu, zvakasanganiswa nemakore mazhinji ehunyanzvi hwekuita basa, kusarudzwa kwetitanium alloy yekucheka maturusi, kutsunga kwekucheka kumhanya, maitiro eakasiyana nzira dzekucheka, machining mvumo uye kugadzirisa matanho ekudzivirira. zvinokurukurwa.Inotsanangura maonero angu uye mazano pamusoro pekugadzira titanium alloys.
Titanium alloy ine yakaderera density, yakakwirira chaiyo simba (simba / density), yakanaka corrosion resistance, high heat resistance, good toughness, plasticity uye weldability.Titanium alloys yakashandiswa zvakanyanya muminda yakawanda.Nekudaro, kushomeka kwemafuta ekupisa, kuomarara kwepamusoro, uye yakaderera elastic modulus zvakare inoita kuti titanium alloys ive yakaoma simbi zvinhu kugadzirisa.Ichi chinyorwa chinopfupikisa mamwe matanho etekinoroji mukugadzirisa kwetitanium alloys zvichienderana nehunhu hwayo hwetekinoroji.
Izvo zvakakosha zvetitanium alloy zvinhu
(1) Titanium alloy ine simba guru, yakaderera density (4.4kg/dm3) uye uremu huremu, iyo inopa mhinduro yekudzikisa huremu hwezvimwe zvikamu zvakakura zvechimiro.
(2) Kunyanya kupisa simba.Titanium alloys inogona kuchengetedza simba rakakwirira pasi pemamiriro e400-500 ℃ uye inogona kushanda zvakadzikama, nepo tembiricha yekushanda yealuminium alloys inogona kunge iri pasi pe200 ℃.
(3) Kana ichienzaniswa nesimbi, iyo yakasikwa yakakwira corrosion kuramba yetitanium alloy inogona kuchengetedza mutengo wekushanda kwezuva nezuva uye kuchengetedza ndege.
Kuongororwa kwemaitiro ekugadzira titanium alloy
(1) Low thermal conductivity.Thermal conductivity yeTC4 pa200 ° C ndeye l = 16.8W / m, uye thermal conductivity ndeye 0.036 cal / cm, iyo inongova 1/4 yesimbi, 1/13 yealuminium uye 1/25 yemhangura.Muchigadziro chekucheka, kupisa kwekupisa uye kutonhora kwekuita kwakashata, izvo zvinopfupisa hupenyu hwekushandisa.
(2) Iyo elastic modulus yakadzikira, uye nzvimbo yakashongedzerwa yechikamu ine hombe rebound, izvo zvinotungamira mukuwedzera kwenzvimbo yekubatana pakati pemashini epamusoro uye nepamusoro pechishandiso, izvo zvisingangokanganisa kurongeka kweiyo. chikamu, asiwo chinoderedza kusimba kwechigadzirwa.
(3) Kuchengetedza kushanda panguva yekucheka kwakashata.Titanium isimbi inopfuta, uye tembiricha yakakwira nepfarivari zvinogadzirwa panguva yekucheka diki zvinogona kukonzera kuti titanium chips itte.
(4) Kuoma kwezvinhu.Titanium alloys ine yakaderera kuomarara kukosha ichave inonamira kana machining, uye machipisi anonamatira kumucheto wekucheka kwechiso cheso chishandiso kugadzira mupendero wakavakwa, unokanganisa machining mhedzisiro;titanium alloys ane hurema hwakanyanya kukosha anowanzo cheka uye abrasion yechishandiso panguva yekugadzira.Aya maitiro anotungamirira kune yakaderera simbi yekubvisa chiyero chetitanium alloy, iyo inongova 1/4 yesimbi, uye nguva yekugadzira yakareba kupfuura iyo yesimbi yehukuru hwakafanana.
(5) Kubatana kwakasimba kwemakemikari.Titanium haigone kuita kemikari chete neiyo huru yenitrogen, okisijeni, kabhoni monoxide uye zvimwe zvinhu zviri mumhepo kuti igadzire yakaomeswa yeTiC neTiN pamusoro peiyo alloy, asi zvakare kuita nechokushandisa pasi pekupisa kwakanyanya. mamiriro anokonzerwa nekucheka, kuderedza chigadziro chekucheka.yekusimba.
