Cov txheej txheem txheej txheej ntawm titanium phaj thiab titanium pas nrig yog qhov tseem ceeb cuam tshuam rau lub cev thiab tshuaj lom neeg ntawm titanium workpiece. Ua ntej machining, txheej txheej paug thiab txheej txheej yuav tsum raug tshem tawm tag nrho. Lub cev mechanical polishing ntawm titanium phaj thiab titanium pas nrig nto polishing txheej txheem:
1. Xuab zeb blasting:
Dawb corundum feem ntau yog siv rau xuab zeb blasting ntawm titanium hlau castings. Lub siab ntawm cov xuab zeb blasting yog me dua li cov hlau tsis muaj nuj nqis thiab feem ntau tswj tau qis dua 0.45MPa. Vim hais tias thaum lub dav hlau siab siab dhau lawm, cov xuab zeb hais yuav cuam tshuam rau titanium nto thiab tsim "qhov hluav taws kub zoo"
Paj, kub nce tuaj yeem hnov mob nrog titanium nto, tsim=cov pa phem thib ob, cuam tshuam rau saum npoo zoo. Lub sij hawm yog 15-30 vib nas this. Tsuas yog tshem tawm cov xuab zeb, sintered txheej thiab ib nrab oxide txheej ntawm qhov chaw casting. Qhov seem txheej txheej txheej txheej txheej txheej yuav tsum tau muab tshem tawm sai sai los ntawm cov tshuaj pickling.
2. Pickling:
Pickling tuaj yeem tshem tawm sai thiab tshem tawm cov txheej txheem saum npoo, thiab qhov chaw yuav tsis muaj kuab lom los ntawm lwm cov khoom. Ob qhov HF-HCL system thiab HF-HNO3 system pickling daws yuav siv tau rau titanium pickling, tab sis HF-HCL system pickling tov muaj ib tug loj hydrogen nqus peev xwm.
Lub peev xwm nqus dej ntawm HF-HNO3 acid pickling kua yog me me, uas tuaj yeem tswj cov concentration ntawm HNO3 kom txo tau hydrogen nqus, thiab tuaj yeem ci ntsa iab. Feem ntau, qhov concentration ntawm HF yog li 39 feem pua 6-5 feem pua, thiab cov concentration ntawm HNO3 yog li 15 feem pua - 30 feem pua.
Cov txheej txheem txheej txheej ntawm titanium phaj thiab titanium pas nrig tuaj yeem raug tshem tawm tag nrho los ntawm kev ntxuav cov kua qaub tom qab xuab zeb blasting.
Ntxiv rau lub cev thiab tshuab polishing, muaj ob hom tshuaj tiv thaiv txheej ntawm titanium phaj thiab titanium pas nrig: 1. tshuaj polishing, 2. electrolytic polishing.
1. Tshuaj polishing:
Thaum lub sij hawm tshuaj polishing, cov hlau yog leveled thiab polished los ntawm oxidation thiab txo cov tshuaj tiv thaiv nyob rau hauv cov tshuaj nruab nrab. Nws qhov zoo yog tshuaj polishing thiab hlau hardness Lub polished cheeb tsam tsis muaj dab tsi ua nrog cov qauv zoo. Txhua qhov chaw sib cuag nrog cov tshuaj polishing yog polished. Tsis muaj cov cuab yeej tshwj xeeb uas yuav tsum tau ua, thiab kev ua haujlwm yooj yim. Nws yog tsim nyog rau polishing lub titanium hniav hniav bracket nrog complex qauv. Txawm li cas los xij, cov txheej txheem tsis zoo ntawm cov tshuaj polishing yog qhov nyuaj los tswj. Nws yuav tsum muaj cov nyhuv polishing zoo ntawm cov hniav hniav, tsis muaj kev cuam tshuam qhov tseeb ntawm cov hniav hniav. Ib qho zoo titanium tshuaj polishing tov yog HF thiab HNO3 npaj nyob rau hauv ib qho kev faib ua feem ntawm -. HF yog tus neeg sawv cev txo qis, uas tuaj yeem yaj cov titanium hlau thiab ua lub luag haujlwm qib. Thaum cov concentration tsawg dua 10 feem pua, HNO3 plays lub luag hauj lwm nyob rau hauv oxidation, tiv thaiv ntau dissolution ntawm titanium thiab hydrogen absorption, thiab nyob rau tib lub sij hawm, nws muaj peev xwm tsim brightness. Titanium polishing tov yuav tsum muaj siab concentration, qis kub thiab luv polishing lub sij hawm (1 ~ 2min).
2. Electrolytic polishing:
Nws tseem hu ua electrochemical polishing lossis anodic dissolution polishing. Vim tias titanium alloy tubes muaj qhov ua tau zoo thiab muaj zog oxidation, lawv tsis tuaj yeem polished nrog aqueous acidic electrolyte xws li HF-H3PO4. HF-H2SO4,
Tom qab siv hluav taws xob sab nraud, titanium anode yuav oxidized tam sim ntawd, yog li ntawd lub anodic dissolution tsis tuaj yeem nqa tawm. Txawm li cas los xij, kev siv anhydrous chloride electrolyte nyob rau hauv qis voltage muaj qhov zoo polishing nyhuv ntawm titanium. Cov qauv me me tuaj yeem ua daim iav polished, tab sis rau kev kho kom yooj yim, lub hom phiaj ntawm polishing tiav tsis tuaj yeem ua tiav. Tej zaum txoj kev hloov cov duab cathode thiab ntxiv cov cathode tuaj yeem daws qhov teeb meem no, uas xav tau kev tshawb fawb ntxiv.
