Titanium alloy yog ib qho alloy muaj cai ntawm titanium thiab lwm cov khoom. Titanium alloy muaj qhov zoo ntawm qhov ceev, muaj lub zog zoo, cov txheej txheem zoo, thiab lwm yam yog cov txheej txheem zoo tshaj plaws rau Aerospace engineering. Hauv qhov chaw tsim ntau lawm, ntau hom kev xeb yuav tshwm sim, feem ntau yog cov hauv qab no:
1, crevice corrosion
Hauv cov hlau tivthaiv pob txha lossis tsis xws luag, vim yog electroly kev daws teeb meem, nyob rau hauv lub qhov tshwm sim electrochion tsis muaj nyob rau hauv tag nrho cov peev xwm ntawm kev sib cav sib ceg, tab sis thaum kawg ua rau muaj kev puas tsuaj perforized.
2, pits tshwm sim
Titanium nyob rau hauv cov ntsev ntau yam tsis muaj penomenon, uas muaj nyob rau hauv cov kev daws teeb meem ntawm tnoAcium passions pitting tshwm sim, pitting aperture yog tsawg dua nws qhov tob. Qee cov organic media thiab titanium alloys hauv Halogen kev daws teeb meem, ntxiv rau hauv cov sulogen thiab chloride pitting yuav tsum muaj qee yam kev mob thiab txwv.
3, hydrogen embrittlement
Hydrogen embrittlement (nws), tseem hu ua hydrogen nrib pleb lossis hydrogen puas tsuaj nrog cov laj thawj, yog li passivation zaj duab xis hydrogenlement yog heev rhiab.
4, hu rau corrosion
Cov zaj duab xis passivated oxide rau saum npoo ntawm titanium presteres lub peev xwm titanium txav mus rau corrosion los ntawm kev kho acidic thiab aqueous. Vim muaj peev xwm ntau dua ntawm cov nplaim dej ntawm titanium alloy, nws yog khi rau corrosion nrog lwm cov hlau nyob rau hauv kev tsim ntawm electrochemical lub voj voog thiab ua rau corrosion. Titanium alloy yog yooj yim los tiv tauj corrosion hauv ob hom xov xwm ntawm 6 txog 60 lub sijhawm, HCOATE ERCROSIONSE SOLD, thiab lwm yam. Lub xeev passivation, tej zaum yuav nyob rau hauv lub xeev ua kom lub xeev ua kom muaj kev ua kom muaj kev tiv thaiv corrosion yog ib txwm muaj rau thawj hom kev daws teeb meem. Anodization feem ntau yog siv los ua ib txheej hloov kho nyob rau saum npoo ntawm substrate los tiv thaiv kev tiv thaiv corrosion.
