Taw qhia ntawm Grra ntshiab Titanium

Gr2 belongs rau ib leeg-emihas muaj ntshiab titanium, uas muaj tsawg me me, siab melting point, thiab muaj zog corrosion tsis kam. Nws muaj qhov zoo ntawm cov khoom siv zoo thiab biocompatibility. Nws yog dav siv nyob rau hauv aerospace, nkoj nkoj thiab biomedicine. Txawm li cas los xij, vim nws cov thermal qis conductivity, yooj yim sab npoo oxidation, thiab qis elastic modulus, qhov kub me yog tsim thaum lub sij hawm txiav thiab nws yog qhov nyuaj rau dissipate. Cov chips yog ib qho yooj yim los lo rau riam, uas ua rau hauv cov khoom tsis zoo thiab lub neej luv. Cov khoom lag luam tseem ceeb yog tuav, daim hlau, kav dej, titanium strips, thiab lwm yam.

 

Tshuaj lom neeg cov khoom: Titanium muaj cov tshuaj lom neeg siab thiab tuaj yeem ua rau muaj ntau yam. Nws tuaj yeem hnov ​​mob nrog cov pa roj carbon monoxide, carbon dioxide, dej vapor, ammatile, thiab ntau yam khoom siv volatile ntawm cov huab cua kub. Titanium reacts nrog qee cov roj av, tsis tsuas yog tsim cov pa taws rau saum npoo av tab sis tseem nkag mus rau cov hlau lattice los tsim cov kev daws teeb meem. Tsuas yog hydrogen, cov txheej txheem tshuaj tiv thaiv yog tsis paub cai.

 

Oxidation tsis kam: Thaum titanium yog rhuab nyob rau hauv ib txwm ua hauj lwm kub, nws tsim cov khoom siv kub heev, ntom, thiab ruaj ntseg oxide zaj duab xis. Nws muaj cov nyhuv tiv thaiv thiab tiv thaiv cov pa oxygen los ntawm qhov sib txawv ntawm cov hlau tsis muaj oxidation ntxiv; Yog li ntawd, titanium yog ruaj khov hauv huab cua hauv qab 500 degree. Hauv qab 538 degree, oxidation ntawm titanium conforms rau txoj cai parabolic. Thaum qhov kub tau tshaj 800 degree, oxide zaj duab xis decomposes, uas nce cov duab oxygen ntawm titanium thiab tuab cov yeeb yaj kiab oxes. Nyob rau lub sijhawm no, cov yeeb yaj kiab oxide tsis muaj kev tiv thaiv thiab ua rau muaj nkig.

 

Forging: Qhov kub kub ntawm lub ingot yog ingot yog ingot yog {}}} degree, thiab deformation ntawm txhua cov hluav taws yog tswj hwm ntawm 40% {%. Cov cua kub kub ntawm kev zam txim yog {}}} degree, thiab kev deformation yog tswj hwm ntawm 30% {}}%. Lub cua sov kub ntawm kev tuag forging yog {}}} degree, thiab qhov kawg tsis quav ntsej txog 650 degree. Txhawm rau kom ua tiav qhov kev xav tau loj ntawm qhov chaw tiav, qhov chaw txuas cua sov txuas ntxiv yuav tsum tsis pub tshaj 815 Degree, lossis txog 95 degree m qis dua li kev hloov pauv kub.

 

Casting: nyob rau hauv lub casting ntawm kev lag luam ntawm kev lag luam titanium, cov kab hlau ua lossis tawm hauv lub tshuab nqus hluav taws xob thiab nrum hauv lub tshuab nqus hluav taws xob arc rauv. Lub Casting pwm tuaj yeem yog cov qauv txheej txheem yooj yim, cov qauv graphite Nias hom, thiab hom HELT HELT.
