tshawb:
Cov cuab yeej hlau thiab cov cuab yeej siv tau rau lub tshuab chaw ntau pob. Speed thiab raws li cov ces kaum thiab cov tshuaj yuav tsum tau xyuas kom tsis txhob galling.
txoj siav:
Saib cov lus qhia rau txoj siav vanadium muab hauv rooj 1. Cov lus qhia no kuj pom zoo
ua ib taw tes rau kev ua hauj lwm nrog vanadium. Kev kho kom cov txheej txheem no yuav tsum ua kom haum raws li tus txawv compositions ntawm txhua vanadium alloy.
Daim ntawv
Vanadium muaj excellent ua hauj lwm zog thiab yuav tau forged, kub los yog yob ntawm chav tsev kub. Annealing yog tsim nyog tom qab 80 ntsaub 85% Txo tau kev txo cov khaub lig. nqus plua plav (<1 x 10-4 TORRN) Ntawm 900° C rau C 1-1/2 teev yuav ua kom tiav recrystallization uas txias ua hauj lwm. Vanadium yog zoo suited mus sib sib zog nqus thiab exhibits me springback.
Vanadium tsis yuav redily anodized xws li lwm yam refractory thiab refractory hlau. Tantalum daim ntawv tshaj tawm films rau capacitors tab sis vanadium (Txawm tias ua ib tiv thaiv oxide uas tsis muaj peevxwm tsawg) Yuav tsis teb cov lus nyom anodizing txheej txheem. Tus qauv oxide ntawm vanadium yog V205 uas melts ntawm 675° C thiab yog corrosive. Vanadium thiab nws yog alloys yuav tsum tau fabricated hauv qab lub melting taw tes ntawm lub oxide los yog yuav tsum tiv thaiv los ntawm ib cov cua oxidizing yog muaj peevxwm siv.
Welding:
raws li Chaw ntau pob vanadium lwm tus neeg, Peb paub tias nws yog reactive uas muaj roj nitrogen nitrogen, pa thiab hydrogen, li no, kev ceev faj yuav tsum tau tiv thaiv tej weld ntawm cov gases. TSOV thiab plasma welding ua hauj lwm zoo thaum precautions noj rau dej nyab tag nrho cov chaw ntawm cov weld (hauv ntej & qaum tes) ntxias (argon, nruab nrab).
Vanadium yuav tau welded rau feem ntau ntawm cov hlau hlau thiab lawv alloys. Welding nrog titanium, nqaij nyug, Tantalum thiab chromium thiab raws li austenitic thiab ferritic stainless tau zoo. Welding rau lwm steels tau yog chromium yog nkag tau rau hauv lub welding thaum lub sij hawm uas welding.
