Titanium hmoov

Yam khoom dab tsi yog titanium hmoov? Nws cov tshuaj muaj pes tsawg leeg thiab lub cev muaj zog yog dab tsi? Nws daim ntawv thov teb yog dab tsi? Cia peb kawm txog titanium hmoov ua ke.
Titanium hmoov yog cov hmoov hlau ua los ntawm titanium. Nws yog cov hmoov dawb-grey tsis tu ncua thiab feem ntau siv hauv aerospace, tshuaj tsuag, metallurgy, foob pob hluav taws thiab lwm yam lag luam.

Titanium hmoov kuj muab zais rau hauv peb lub neej txhua hnub. Piv txwv li: Thaum lub caij so, peb pom cov foob pob hluav taws thiab cov foob pob hluav taws tawg hauv ntau cov xim, thiab cov khoom tseem ceeb ntawm cov xim muaj xim yog titanium hmoov. Ntawm chav kawm, qhov no tsuas yog qhov tsawg tshaj plaws ntawm kev siv.

foob ​​pob hluav taws

Titanium hmoov (hydrogenated) yog xim dub-grey irregular hmoov.

Titanium hmoov muaj ntau yam kev siv, feem ntau suav nrog cov hauv qab no:

Titanium hmoov thiab titanium hydride hmoov yog hlau hmoov nrog ntau yam kev siv. Nws yog ib qho additive rau hmoov metallurgy thiab alloy cov ntaub ntawv. Nws tseem yog ib qho tseem ceeb raw cov ntaub ntawv rau cermets, deg coating agents, aluminium alloy additives, hluav taws xob nqus getters, txau thiab plating. Titanium hmoov yog siv los ua ntau yam khoom, nrog rau cov khoom siv tseem ceeb, cov phab ntsa, cov iav tsaws, cov kav dej thiab cov tshuab hydraulic. Kuj tseem siv hauv aerospace, tshuaj tsuag, metallurgy, foob pob hluav taws thiab lwm yam lag luam.

Lub ntsiab tsis yog: particle loj (mesh tooj), titanium cov ntsiab lus, hydrogen cov ntsiab lus, kais ceev, thiab lwm yam.

Titanium hmoov muaj nuj nqi:
1. Tshuaj muaj pes tsawg leeg
Nws tsuas yog hais txog cov ntsiab lus ntawm titanium hlau thiab cov ntsiab lus ntawm impurities. Qhov siab dua cov ntsiab lus titanium hauv titanium hmoov, qhov qis dua cov ntsiab lus impurity, siab dua qhov purity thiab siab dua qib ntawm titanium hmoov. Cov hmoov zoo titanium feem ntau muaj cov pa oxygen qis tshaj plaws, yog li qhov zoo ntawm titanium hmoov feem ntau nyob ntawm cov ntsiab lus oxygen hauv nws.
2. Lub cev muaj zog
titanium hmoov muaj zog ntau dua li cov hlau titanium thiab feem ntau yuav hnov ​​​​mob nrog lwm cov ntsiab lus lossis cov khoom sib txuas. Nws yog yooj yim oxidized, flammable, thiab tawg, thiab yog ib yam khoom txaus ntshai. Yog li ntawd, titanium hmoov ntim muaj cov kev cai tshwj xeeb. Thaum ntim titanium hmoov, lub tshuab nqus tsev yuav tsum tau siv. Lub ntim sab nrauv yog tiv thaiv los ntawm inert gas argon thiab lub ntim txheej siv lub thoob tawg-pov thawj.
Kev tsim cov titanium hmoov
Muaj ntau txoj hauv kev los tsim cov titanium hmoov, nrog rau cov khoom siv hlau, hydrodehydrogenation (HDH), atomization, hlau thermal txo thiab molten ntsev electrolysis.
Tam sim no, txoj kev siv ntau tshaj plaws hauv Suav teb yog hydrogenation dehydrogenation (HDH). Hydrodehydrogenation yog txheej txheem uas siv cov khoom thim rov qab ntawm titanium thiab hydrogen los npaj titanium hmoov. Txoj kev HDH siv daim txhuam cev titanium los ua nkig tom qab nqus cov hydrogen thiab yooj yim crushed mechanically los tsim titanium hydride hmoov, uas yog tom qab ntawd dehydrogenated ntawm qhov kub thiab txias hauv lub tshuab nqus tsev los tsim cov hmoov ntshiab titanium.
Titanium hmoov txheej txheej txheem
1 Siv cov kab rov tav hydrogenation rauv, cov tshuaj tiv thaiv hydrogenation tshwm sim thaum qhov kub thiab txias tau nce siab tshaj 350 degree nyob rau hauv qhov zoo hydrogen siab. Thaum qhov kub thiab txias tau nce ntxiv, cov tshuaj tiv thaiv pib ua nruj ua tsiv, thiab ntau cov hydrogen absorbed sai heev. Cov hydrogen hla dhau thiab khaws cia rau 3 teev, thiab tom qab ntawd hauv qhov chaw hydrogen. Tom qab maj mam txias rau chav sov, titanium hydride hmoov nrog cov ntsiab lus hydrogen ntawm 3.8% ± 0.2% tuaj yeem tau.
2. Ua lub pob milling nyob rau hauv kev tiv thaiv ntawm cov roj tiv thaiv, uas tuaj yeem tiv thaiv cov titanium hmoov kom tsis txhob muaj kab mob thiab zam qhov tshwm sim ntawm ntuj titanium hydride, ua kom muaj kev nyab xeeb ntawm kev tsim khoom.
3.Titanium hydride nrog ntau qhov sib txawv tuaj yeem tau txais los ntawm pob milling. Muab cov av titanium hydride tso rau hauv lub qhov cub kom dehydrogenation cov tshuaj tiv thaiv. Nyob rau hauv lub tshuab nqus tsev, qhov kub nce mus txog 680 degree. Lub sijhawm no, titanium hydride sai sai decomposes thiab tso tawm hydrogen. Tag nrho cov txheej txheem dehydrogenation tswj lub tshuab nqus tsev qis thiab txuas ntxiv Txog 19h, titanium hmoov tau kawg.
4. Muab faib cov titanium hmoov ntawm qhov sib txawv ntawm qhov ntau thiab tsawg los ntawm cov ntxaij vab tshaus (kev tshuaj ntsuam xyuas) nrog cov mesh sib txawv.
