Kev Taw Qhia Kom Paub Txog Kev Siv Titanium Phaj
Titanium yog ib qho inert hlau, nws cov cim tshuaj yog atomic tooj 22, thiab nws yog ib tug silvery hlau. Lub ntiajteb txawj nqus 4.51, melting point 1668 degree. Nws cov reserves nyob rau hauv lub ntiaj teb crust yog nplua nuj heev, thiab nws nyob rau qib plaub tom qab hlau, txhuas thiab magnesium, ntau tshaj kaum npaug ntau tshaj li cov feem ntau siv hlau tooj liab, npib tsib xee, txhuas thiab zinc.
Cov ores siv los tsim titanium hauv kev lag luam muaj xws li rutile, ilmenite thiab titanomagnetite. Vim qhov nyuaj ntawm kev cais tawm, cov hlau titanium ntawm kev lag luam tseem ceeb tsis tau tsim kom txog rau thaum xyoo 1940. Yog li ntawd, titanium feem ntau hu ua lub teeb hlau tsis tshua muaj. Vim tias qhov sib txawv ntawm cov khoom sib txawv ntawm cov khoom sib txawv, titanium thiab titanium alloy cov khoom sib txawv.
Cov neeg ua haujlwm rau hauv daim hlau, rods, raj, strips, xov hlau, thiab lwm yam, uas tuaj yeem siv rau hauv cov txheej txheem sib sib zog nqus kom tau raws li ntau qhov kev xav tau kom tau raws li cov kev xav tau ntawm ntau qhov chaw. Ntawm lawv, titanium daim hlau, titanium rings, titanium forgings thiab lwm yam kev siv yog feem ntau. Cov lus qhia tshwj xeeb thiab cov khoom ntawm titanium daim hlau feem ntau siv hauv kev lag luam tshuaj yog qhia hauv qab no. Qhov saum npoo ntawm titanium phaj yuav tsum ci thiab xim hlau.
Cov ntawv tso cai xa tuaj nrog sandblasted tiav. Qhov saum npoo ntawm titanium phaj tau tso cai kom muaj qhov tsaus me ntsis thiab qee qhov dej cim; qee qhov tsis xws luag raug tso cai, xws li khawb, indentations, pits thiab lwm yam tsis xws luag uas tsis pub tshaj ib nrab ntawm cov thickness kam rau ua, tab sis lub thickness yuav tsum me me. Cov tsos mob tsis raug tso cai kom muaj cov kab mob macroscopic xws li cov kab nrib pleb, tev, oxide daim tawv nqaij, folds, hlau thiab tsis-hlau inclusions thiab kab ntawm alkali ntxuav. Titanium daim hlau raug tso cai kom muaj qee qhov tsis xws luag raws li cov kev taw qhia dov, tab sis lub thickness ntawm lub phaj tom qab ntxuav tsis tsawg tshaj li qhov tso cai thickness.
