Kev daws teeb meem ntawm qhov tsis xws luag cov tshuaj tiv thaiv txheej txheej ntawm titanium alloy phaj thiab titanium alloy pas nrig

Qhov txheej txheej txheej txheej ntawm titanium phaj thiab titanium pas nrig yog qhov tseem ceeb cuam tshuam rau lub cev thiab tshuaj lom neeg ua haujlwm ntawm titanium workpiece. Ua ntej ua tiav, cov txheej txheem ua pa phem thiab cov txheej txheem tsis zoo yuav tsum raug tshem tawm tag nrho. Lub cev tshuab polishing ntawm titanium phaj thiab titanium pas nrig nto polishing txheej txheem:

Xuab zeb tawg

Kev kho sandblasting ntawm titanium hlau cam khwb cia qhov chaw feem ntau xaiv cov tshuaj dawb corundum zoo dua, lub siab ntawm cov xuab zeb blasting lub cev me dua li cov hlau tsis muaj nuj nqis, feem ntau tswj hauv qab no 0.45MPa. Vim hais tias, thaum lub zog txhaj tshuaj loj dhau lawm, cov xuab zeb particle shocks titanium nto los tsim cov nplaim taws, qhov kub nce tuaj yeem hnov ​​​​mob nrog titanium nto, tsim cov pa phem thib ob, cuam tshuam rau saum npoo zoo. Lub sijhawm yog 15-30 vib nas this, tsuas yog tshem tawm cov xuab zeb nplaum ntawm qhov chaw casting, txheej txheej sintering thiab ib nrab oxide txheej tuaj yeem raug tshem tawm. Tus so ntawm cov tshuaj tiv thaiv txheej txheej txheej yuav tsum tau muab tshem tawm sai sai los ntawm cov tshuaj pickling txoj kev.

Acid pickling

Acid ntxuav tuaj yeem tshem tawm cov tshuaj tiv thaiv txheej txheem sai thiab tshem tawm tag nrho yam tsis muaj qhov ua rau muaj kab mob ntawm lwm yam. HF-HCL thiab HF-HNO3 series tuaj yeem siv rau titanium pickling, tab sis HF-HCL series hydrogen absorption tus nqi, thiab HF-HNO3 series hydrogen absorption yog me me, tuaj yeem tswj cov concentration ntawm HNO3 kom txo tau hydrogen nqus, thiab kho lub teeb pom kev zoo. , qhov concentration ntawm HF concentration ntawm li 3 feem pua ​​-5 feem pua, HNO3 concentration ntawm li 15 feem pua ​​-30 feem pua ​​yog tsim nyog.

Cov txheej txheem txheej txheej txheej ntawm titanium phaj thiab titanium pas nrig tuaj yeem tshem tawm cov txheej txheem titanium los ntawm pickling tom qab sandblasting.

Ntxiv nrog rau lub cev thiab tshuab polishing, muaj ob txheej txheej txheej txheej ntawm titanium phaj thiab titanium pas nrig, raws li nram no: 1. tshuaj polishing, 2. electrolysis polishing.

Tshuaj polishing

Lub hom phiaj ntawm cov tshuaj polishing yog ua tiav los ntawm cov tshuaj tiv thaiv redox ntawm cov hlau hauv cov tshuaj nruab nrab. Nws qhov zoo dua yog tias cov tshuaj polishing thiab hardness ntawm cov hlau, polishing cheeb tsam tsis muaj dab tsi ua nrog cov qauv ntawm cov qauv, tag nrho cov khoom nyob rau hauv kev sib cuag nrog cov kua polishing yog polished, tsis muaj cov khoom tshwj xeeb complex, yooj yim rau kev khiav lag luam, ntau haum rau. polishing ntawm cov qauv complex titanium hniav hniav bracket. Txawm li cas los xij, cov txheej txheem tsis zoo ntawm cov tshuaj polishing yog qhov nyuaj rau kev tswj hwm, uas yuav tsum muaj cov nyhuv polishing zoo ntawm cov hniav nyiaj hniav kub tsis cuam tshuam qhov tseeb ntawm cov hniav hniav. Zoo dua titanium tshuaj polishing kua yog HF thiab HNO3 npaj raws li ib qho kev faib ua feem, HF yog ib tug txo tus neeg sawv cev, muaj peev xwm yaj titanium hlau, ua si ib theem nyhuv.

Electropolishing

Kuj hu ua electrochemical polishing los yog anode dissolution polishing, vim hais tias ntawm cov hluav taws xob conductivity ntawm titanium alloy raj yog tsawg, tsis tshua muaj zog oxidation kev ua tau zoo, kev siv dej acid electrolyte xws li HF-H3PO4, HF-H2SO4 series electrolyte rau titanium yuav luag tsis polishing, Tom qab siv cov hluav taws xob sab nraud, titanium anode tam sim ntawd oxidation, thiab anode dissolution tsis tuaj yeem nqa tawm. Txawm li cas los xij, kev siv cov tshuaj anhydrous chloride electrolyte ntawm qhov tsis tshua muaj hluav taws xob, muaj cov nyhuv polishing zoo ntawm titanium, cov qauv me me tuaj yeem tau txais daim iav polishing, tab sis kev kho nyuaj tseem tsis tuaj yeem ua tiav lub hom phiaj ntawm polishing tiav, tej zaum siv cov kev hloov ntawm cathode duab thiab ntxiv. txoj kev cathode los daws qhov teeb meem no, nws yuav tsum tau kawm ntxiv.
