Titanium

Titanium (Ti), IVB pawg lub caij ntawm plaub lub sij hawm ntawm lub sij hawm lub sij hawm, yog ib tug silver-dawb hloov hlau. Cov khoom zoo ntawm lub cev thiab tshuaj lom neeg ua rau nws siv dav hauv aerospace (fuselage thiab engine), petrochemical (condenser, heat exchange tube), lub teb chaws tiv thaiv ( missile thiab foob pob ua ntxaij) thiab kev kho mob biology (cov pob txha pob txha), thiab lwm yam high-end teb.

Qhov tseem ceeb tshaj plaws ntawm lub cev thiab tshuaj lom neeg ntawm titanium suav nrog cov ntsiab lus melting siab thiab lub zog tshwj xeeb. Titanium tsuas yog 57 feem pua ​​​​ntawm cov hlau.

Lub melting point yog 1668 degree, 138 degree siab tshaj hlau. Lub zog tshwj xeeb (lub zog / pom tseeb) ntawm titanium yog qhov loj tshaj plaws hauv cov khoom siv feem ntau siv. Lub zog tshwj xeeb ntawm feem ntau siv TC4 titanium alloy (Ti-6Al-4V) yog 3.5 npaug ntawm cov hlau tsis muaj steel, yog li titanium yog ib hom ntawm lub zog siab thiab cov hlau tsis zoo.

Titanium alloy

Titanium alloy yog cov khoom siv ua haujlwm siab siv hauv cov khoom siv dav hlau, nrog cov khoom siv hlau zoo heev, tam sim no thoob ntiaj teb lees paub tias yog cov khoom siv siab tshaj plaws thiab zoo tshaj plaws rau kev tsim txhua yam kev sib tw thiab caij tsheb kauj vab qib siab. Cov yam ntxwv zoo ntawm titanium alloy yog lub teeb yuag, siab zog, zoo elasticity, cuam tshuam tsis kam, zoo qaug zog kev ua haujlwm, corrosion kuj thiab tsis xeb. Cov tsheb kauj vab, tshwj xeeb tshaj yog cov tsheb sib tw, xav tau lub teeb yuag, nruj, thiab kev ua haujlwm zoo. Qhov hnyav dua txhim kho qhov nrawm thiab txo lub cev kev tawm dag zog ntev ntev; Lub tsheb kauj vab ncej nrog zoo rigidity yog qhov tsim nyog rau kev hloov pauv ntawm kev tsav tsheb thiab txhim kho kev tuav haujlwm. Lub tsheb kauj vab thav duab nrog kev cuam tshuam zoo tuaj yeem txo qhov cuam tshuam los ntawm txoj kev, kom txo tau qhov qaug zog ntawm tus neeg caij tsheb.

Titanium yob

(1) Kub dov titanium phaj yog thawj zaug rhuab nyob rau hauv lub alkali rauv (salt da dej cua sov txoj kev nyob rau hauv uas cov khoom sodium hydroxide los ua ib tug kua lub xeev ntawm kub). Cov cua kub cua sov yog nruab nrab ntawm 400 degree thiab 460 degree. Kho cov cua kub thiab tuav lub sij hawm raws li qhov sib txawv thicknesses ntawm titanium phaj. Txhawm rau tshem tawm cov sodium hydroxide molten kua rau ntawm qhov chaw ntawm titanium phaj thiab cov nyhuv descaling, vim yog lub phaj titanium thiab qhov chaw ntawm cov nplai oxide nyob rau hauv cov ntaub ntawv ntawm qhov kub thiab txias ntawm thermal expansion thiab contraction, nyob rau hauv dej txias quenching, yog li ntawd. tias qhov chaw ntawm cov oxide nplai tawm, cov txheej txheem no hu ua alkali tawg.

(2) Cov kua qaub yog sulfuric acid thiab sodium nitrate molten kua. Thaum cov hlau ion nyob rau hauv cov tshuaj ntau tshaj ib tug xov tooj, nws yuav ua rau lub nto xim ntawm lub titanium phaj yog dub thiab tsis mus txog qhov kawg, yog li nws yog tsim nyog los tsis tu ncua los yog quantitatively ntes cov hlau ion ntsiab lus nyob rau hauv cov kua qaub.

(3) Pickling rau hauv lub tshuab dov tom qab dov, dov cov khoom tiav, alkali ntxuav (sodium hydroxide dej yaj) kom tshem tawm cov roj saum npoo.

(4) Tom qab alkali ntxuav, nws yog qhuav nyob rau hauv qhov cub cua sov (gas cua sov rauv). Lub qhov cub kub yog tswj hauv qab 200 degree, thiab cov txheej txheem ziab yog feem ntau 180 degree.

(5) Tom qab ziab, nkag mus rau thaj chaw khoom tiav. Ua ntej, ncaj rau saum npoo ntawm lub tshuab rau 6-roller straightening, thiab tom qab ntawd txiav rau hauv qhov loj ntawm qhov tiav ntawm lub phaj shearing tshuab. Thaum kawg, manually kho qhov chaw tsis xws luag nrog Chiba sib tsoo log, thiab thaum kawg pob. Nyob rau hauv cov txheej txheem saum toj no, vim hais tias lub titanium phaj yog thawj rhuab nyob rau hauv lub alkali rauv, lub cub tawg siv hluav taws xob cua sov, uas siv lub zog loj, thiab lub tshav kub poob ntawm lub alkali da dej rauv yog loj, lub zog siv tus nqi yog tsawg, thiab cov khoom. sodium hydroxide yog siv los ua cov kua molten nyob rau hauv alkali rauv, thiab cov kua khib nyiab yog phem heev rau ib puag ncig. Tsis tas li ntawd, cov txheej txheem no yuav siv sij hawm ntev los tshem tawm cov oxide nplai, thiab cov khoom tsim tau qis, qhov tseem ceeb tshaj plaws yog tias cov txheej txheem uas twb muaj lawm yog qhov nyuaj rau kev ua tiav cov khoom tsim tawm tas li.
