Tham txog qhov tsis ua hauj lwm tsom xam ntawm qhov zoo ntawm cov khoom titanium phaj
Titanium phaj muaj kev ua tau zoo heev, muaj zog tshwj xeeb, kev ua haujlwm kub nruab nrab zoo, tsis muaj hlau nplaum thiab lwm yam zoo, thiab nws tau siv dav hauv pej xeem. Hauv kev tsim khoom, peb pom tias qhov zoo ntawm cov khoom titanium phaj yog qhov ua txhaum ntau
Muaj ntau hom kev xeb, plua plav, tsis tshem tawm oxide nplai thiab streaky mottling.
1. Tshaj-corrosion: Tshaj-corrosion yog hais txog qhov pom ntawm qhov pits lossis qhov tsis sib xws ntawm qhov chaw ntawm titanium phaj tom qab pickling, uas txawv ntawm cov khoom siv. - Feem ntau, qhov ua rau over-corrosion defects yog qhov tsis sib xws ntawm qhov sib piv ntawm hydrofluoric acid thiab nitric acid. Cov concentration ntawm hydrofluoric acid ntau dhau los yog tsis txaus siab ntawm nitric acid tuaj yeem ua rau qhov teeb meem no. Lwm qhov laj thawj yog tias lub sijhawm pickling ntev dhau lawm. Nws yog 1mm ~ 4min, thiab cov txheej txheem tsis tuaj yeem hloov kho raws li qhov chaw ua haujlwm kom tsim nyog luv lub sijhawm pickling.
2. Cov tshauv dai: Cov tshauv dai yog hais txog cov oxide txuas rau saum npoo ntawm titanium phaj tom qab pickling. Thaum lub sij hawm pickling, lub qhuav titanium alloy thiab cov kua qaub ua rau muaj tshuaj lom neeg cov tshuaj tiv thaiv, thiab cov generated oxide accumulates nyob rau saum npoo, tiv thaiv cov tshuaj tiv thaiv los ntawm kev mus.
Ib kauj ruam tshwm sim. Qhov tsis xws ntawm cov tshauv dai feem ntau yog tshwm sim los ntawm cov tshauv ntau dhau thaum lub sij hawm pickling thiab tsis txaus ntxuav tom qab pickling. Thaum lub sij hawm pickling, cov khoom yuav tsum tau shaken tas li kom cov khoom reacted ntog ntawm lub titanium alloy. Tom qab pickling, tshuaj tsuag los yog ntxuav yuav tsum muaj zog kom tshem tawm cov tshauv. Peb lub teb chaws feem ntau txais cov dej ntws ntawm compressed cua thiab kais dej los ntxuav qhov chaw, thiab cov nyhuv yog zoo.
3. Cov nplai oxide tsis raug tshem tawm: Muaj ntau ntau qhov laj thawj rau qhov tsis xws luag, thiab tag nrho cov txheej txheem tuaj yeem ua tau. Nws yog qhov ua tau tias cov roj tshem tawm tsis zoo, lossis lub sijhawm kho ntsev ntsev tsis txaus, los yog cov tshuaj pickling tsis raug. Thaum qhov teeb meem no tshwm sim, txhua yam ua tau yuav tsum raug tshem tawm ib qho los ntawm ib qho, thiab thaum tsim nyog, sandblasting tuaj yeem muab ntxiv rau kev kho ua ntej.
4. Striped mottling: Qhov ua rau ntawm qhov tsis xws luag no feem ntau yog vim qhov tsis sib xws. Nws tuaj yeem raug tshem tawm los ntawm kev txav qhov chaw thaum lub sij hawm pickling thiab txo qhov kub ntawm cov kua pickling. Ntxiv nrog rau cov kev tsis txaus siab saum toj no
Qee lub sij hawm nws pom tias cov khoom titanium phaj uas tau dhau qhov kev tshuaj xyuas tom qab pickling yuav muaj mottling ntawm qhov chaw tom qab ib lub sij hawm. Muaj qee qhov kev tshawb fawb txog qhov tshwm sim no. Nws tuaj yeem tshwm sim los ntawm qhov muaj cov kua qaub seem ntawm qhov chaw tom qab pickling lossis muaj cov xov xwm corrosive coj los ntawm kev tsim khoom tom ntej. Qhov sib txawv, feem ntau hais lus, tsis cuam tshuam rau nws qhov kev ua tau zoo, thiab tuaj yeem raug tshem tawm los ntawm kev rov qab ua dua, tab sis qhov kev ntxhov siab yuav tsum tau ntxiv dag zog kom tshem tawm hydrogen tom qab ob lub pickling.
