Titanium hlau qhia
Titanium hlauyog muab faib ua titanium hlau, titanium alloy hlau, thiab lwm yam.
Titanium yog nyiaj-dawb hloov hlau nyob rau hauv pab pawg IVB ntawm lub sij hawm ntawm lub ntsiab lus. Nws tus lej atomic yog 22 thiab nws cov txheeb ze atomic loj yog 47.87. Nws tuaj yeem hlawv nyob rau hauv nitrogen thiab muaj lub siab melting point. Nws tau pom nyob rau hauv Cornwall, England, los ntawm William Gregor hauv 1791, thiab muaj npe los ntawm Martin Heinrich Klaproth tom qab Titan ntawm Greek mythology. Titanium-muaj ore yog refined kom tau titanium daim txhuam cev, uas yog smelted los ua titanium ingots.
Kev lag luam tus nqi ntawm titanium pib tau lees paub hauv xyoo 1950, thiab nws yog ib qho tseem ceeb ntawm cov khoom siv tseem ceeb uas yuav tsum tau ua rau kev txhim kho qib ntawm cov cuab yeej tiv thaiv hauv teb chaws.
cov khoom ntawm cov khoom
Ob qho khoom siv zoo tshaj plaws ntawm cov hlau yog corrosion kuj thiab lub zog-rau-qhov sib piv, qhov siab tshaj plaws ntawm cov khoom siv hlau. Hauv nws qhov xwm txheej tsis sib xws, titanium muaj zog npaum li qee cov hlau tab sis ntom ntom.

welding ntawm titanium khoom
Tag nrho cov vuam ntawm titanium yuav tsum tau ua nyob rau hauv ib qho inert cua ntawm argon los yog helium los tiv thaiv nws los ntawm kev paug nrog atmospheric gases (oxygen, nitrogen, thiab hydrogen). Kev sib kis ua rau muaj ntau yam xwm txheej, xws li embrittlement, uas txo qhov kev ncaj ncees ntawm kev sib dhos welds thiab ua rau kev sib koom ua tsis tiav.
