Yim Yam Lus Me Me Txog Titanium

Feem ntau cov kev xav tsis zoo txog titanium thiab titanium alloys tau teev tseg raws li qee qhov yuam kev ntau dua:
Tswvyim #1: Titanium ua cua sov sai dua txhuas
Cov tshuaj zoo: titanium thermal conductivity tsawg heev, thiab stainless hlau ze li ntawm 1/14 ntawm txhuas, hlau 1/5. ua noj yog ib qho yooj yim rau paste yog vim li no.
Tswv yim ob: siab purity titanium hardness yog loj heev
Qhov zoo: ntshiab titanium hardness tsawg heev, tsawg dua 120 Brinell hardness. Tab sis kab impurities tuaj yeem txhim kho nws qhov nyuaj, siv sab nraum zoov yog nws cov alloys.

Lus dab neeg 3: Titanium yog cov hlau tsis tshua muaj, lub ntiaj teb cov ntsiab lus tsawg heev.
Cov tshuaj zoo: cov ntsiab lus ntawm titanium tso nyiaj rau 0.6% ntawm lub ntiaj teb, suav rau cuaj.
Tswvyim No. 4: Titanium muaj lub ntiajteb txawj nqus me dua li txhuas.
Muaj tseeb: Titanium muaj qhov ceev ntawm 4.51, thaum txhuas yog tsawg dua 2.7. Aluminium pans hnyav dua vim lawv tuab heev! Kuv tshwj xeeb tshaj yog nco cov qub puag ncig aluminium su lub thawv!
Lus dab neeg 5: Titanium yog tshuaj tsis muaj zog.
Muaj tseeb: ntom titanium yog tus nyob ruaj khov nyob rau hauv huab cua, tab sis yog qhov kub thiab tuaj yeem cuam tshuam nrog haloogen, carbon monoxide, carbon dioxide, thiab ammonia. Ceev faj thaum qhuav hlawv sab nraum zoov!
Tswvyim No. 6: Titanium hlau yog heev corrosion resistant rau muaj zog acids thiab alkalis
Qhov zoo: Titanium yog yooj yim yaj hauv hydrofluoric acid, concentrated sulfuric acid, concentrated hydrochloric acid thiab aqua regia; Nws tsis yaj nyob rau hauv alkali daws, tab sis nws muaj peev xwm cuam tshuam nrog molten alkali.
Lus dab neeg 7: titanium tsis yooj yim rau oxidize
Cov tshuaj zoo: titanium hlau thiab txhuas yog yooj yim rau oxidation cov tshuaj tiv thaiv, tsim oxide zaj duab xis, tiv thaiv oxidation ntxiv. Cov txheej txheem Anodizing kuj tseem yooj yim ua.
Tswvyim No. 8: Feem ntau ntawm cov khoom siv titanium hauv ntiaj teb no yog siv hauv aerospace thiab hnyav kev lag luam thiab lwm yam.
Kev daws: Feem ntau ntawm cov titanium ore tsim nyob rau hauv lub ntiaj teb no txhua txhua xyoo yog siv rau zus tau tej cov titanium dioxide pigments.
