ASTMB265 titanium phaj nto tsis xws luag cov tshuaj tiv thaiv txheej yuav ua li cas nrog

ASTMB265 titanium phaj nto cov tshuaj tiv thaiv txheej yog qhov tseem ceeb cuam tshuam rau lub cev thiab tshuaj lom neeg cov khoom ntawm titanium workpieces, ua ntej ua, yuav tsum ua tiav kev tshem tawm cov txheej txheem paug thiab txheej txheej. Titanium phaj thiab bar nto
Physical mechanical polishing txheej txheem:
1, Sandblasting:
Titanium hlau castings sandblasting kev kho feem ntau zoo dua los siv cov tshuaj dawb corundum, sandblasting siab kom me dua cov hlau tsis muaj nqi, feem ntau tswj ntawm 0.45MPa hauv qab no. Vim hais tias, cov tshuaj tsuag yog loj heev
Thaum cov xuab zeb tuaj yeem cuam tshuam rau saum npoo ntawm titanium los tsim cov nplaim taws, qhov kub siab tuaj yeem hnov ​​​​mob nrog rau saum npoo ntawm titanium, tsim cov pa phem, cuam tshuam rau saum npoo zoo. Lub sij hawm rau 15-30 vib nas this, tsuas yog tshem tawm qhov chaw casting
Lub sij hawm yog 15-30 vib nas this, tsuas yog tshem tawm cov xuab zeb nplaum rau ntawm qhov chaw ntawm cov casting, cov txheej txheej sintered thiab ib feem ntawm oxidized txheej yuav ua tau. Tus so ntawm cov nplaim hluav taws xob txheej txheej yog tsim nyog siv tshuaj lom neeg kom sai.
2. Acid ntxuav:
Kev ntxuav cov kua qaub tuaj yeem tshem tawm cov txheej txheem tawm tsam sai thiab tshem tawm tag nrho, thiab qhov chaw yuav tsis tsim lwm yam kev ua qias tuaj. HF-HCL system thiab HF-HNO3 system pickling tov yuav siv tau rau titanium pickling, tab sis HF-HCL system pickling tov yuav siv tau rau titanium pickling, tab sis HF-HCL system pickling tov yuav siv tau rau titanium pickling.
F-HCL system pickling tov muaj ntau dua hydrogen nqus, thaum HF-HNO3 system pickling kua muaj ib tug me me ntawm hydrogen absorption, lub concentration ntawm HNO3 tuaj yeem tswj tau kom txo tau qhov nqus ntawm hydrogen, thiab saum npoo tuaj yeem ua kom ci kho. , feem ntau yog HF
Feem ntau, qhov concentration ntawm HF yog li 3% -5%, thiab qhov concentration ntawm HNO3 yog li 15% -30%.

Cov tshuaj tiv thaiv txheej nyob rau saum npoo ntawm titanium phaj thiab bar tuaj yeem raug tshem tawm tag nrho los ntawm txoj kev ntxuav cov kua qaub tom qab xuab zeb blasting.
Titanium phaj thiab titanium bar nto cov tshuaj tiv thaiv txheej ntxiv rau lub cev mechanical polishing muaj ob yam, ntsig txog: 1. tshuaj polishing, 2. electrolytic polishing.
1, tshuaj polishing:
Tshuaj polishing los ntawm cov hlau nyob rau hauv cov tshuaj nruab nrab ntawm redox cov tshuaj tiv thaiv thiab ua tiav lub hom phiaj ntawm leveling thiab polishing. Qhov kom zoo dua yog cov tshuaj polishing thiab hlau hardness, polishing cheeb tsam thiab cov qauv duab
Nws qhov zoo dua yog tias cov tshuaj polishing thiab hlau hardness, polishing cheeb tsam thiab cov qauv qauv tsis muaj dab tsi ua, qhov chaw nyob rau hauv kev sib cuag nrog cov tshuaj polishing yog polished, tsis muaj cov cuab yeej tshwj xeeb complex, yooj yim rau kev khiav lag luam, haum rau complex qauv ntawm titanium hniav hniav bracket. polishing. Tab sis cov txheej txheem tshuaj polishing
Txawm li cas los xij, cov txheej txheem tshuaj polishing tsis yooj yim rau kev tswj hwm, cov kev cai ntawm cov hniav hniav tsis cuam tshuam qhov tseeb ntawm cov hniav hniav tuaj yeem muaj cov nyhuv polishing zoo ntawm cov hniav hniav. Qhov zoo dua titanium tshuaj polishing tov yog HF thiab HNO3 npaj rau hauv 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, lub concentration ntawm<10%, HNO3 play an oxidizing role, to prevent excessive dissolution of titanium and hydrogen absorption, and at the same time can produce a bright effect. Titanium
Polishing tov yuav tsum muaj siab concentration, tsawg kub, luv polishing lub sij hawm (1 ~ 2min).
2, electrolytic polishing:
Kuj hu ua electrochemical polishing los yog anodic dissolution polishing, vim tsis tshua muaj conductivity ntawm titanium alloy raj, oxidation zog muaj zog heev, siv cov aqueous acidic electrolyte xws li HF-H3PO4, HF-H2.
SO4 electrolyte ntawm titanium tsis tuaj yeem polished, tom qab siv hluav taws xob sab nraud, titanium anode tam sim ntawd oxidized, thiab anode dissolution tsis tuaj yeem nqa tawm. Txawm li cas los xij, kev siv anhydrous chloride electrolyte ntawm qhov tsis tshua muaj hluav taws xob.
Txawm li cas los xij, kev siv cov tshuaj anhydrous chloride electrolyte ntawm qhov tsis tshua muaj hluav taws xob, titanium muaj cov nyhuv polishing zoo, cov qauv me me tuaj yeem tau txais daim iav polishing, tab sis rau kev kho kom yooj yim tseem tsis tuaj yeem ua tiav lub hom phiaj ntawm polishing tiav, tej zaum los ntawm kev hloov cov duab ntawm cathode thiab txuas
Tej zaum txoj kev hloov cov duab cathode thiab txuas cov cathode tuaj yeem daws qhov teeb meem no, uas xav tau kev tshawb fawb ntxiv.
