Vim li cas Titanium Alloy Anodization ua haujlwm thiab nws ua haujlwm li cas?

​Lub ntuj tsim oxide zaj duab xis nyob rau saum npoo ntawmntshiab titanium alloy yog nyias thiab tsis -compact. Nws yog ib qho nyuaj kom ua tau raws li qhov yuav tsum tau ua hauv kev ua haujlwm nyuaj. Anodization thev naus laus zis tsim kom muaj kev sib koom ua ke, kev ua tau zoo -tuaj yeem oxide zaj duab xis ntawm titanium alloy nto los ntawm cov tshuaj tiv thaiv electrochemical. Qhov no txhim khu kev tiv thaiv corrosion, hnav tsis kam, kho kom zoo nkauj, thiab ua haujlwm zoo. Nws tau dhau los ua ib qho ntawm cov thev naus laus zis tseem ceeb rau kev hloov kho titanium alloy nto.

Degreasing:Tshem tawm cov kab mob organic paug. Tsis txhob muaj cov roj seem thiab cov tshuaj lom neeg.
Pickling:Tshem tawm oxide nplai thiab qhov tsis xws luag. Tiv thaiv kom tsis txhob muaj corrosion ntau dhau ntawm lub substrate.
Kev ntxuav dej:Tiv thaiv kom txhob muaj kab mob los ntawm cov tshuaj residual daws
Yaug nrog kais dej ua ntej, tom qab ntawd dej deionized; yaug yam tsawg kawg 3 zaug tom qab pickling. Rau precision workpieces, kev ua kom muaj zog ntxiv tuaj yeem tiv thaiv kom tsis txhob rov tsim dua oxide nplai.

1. Clamping thiab Circuit Court Connection
Pretreated titanium alloy workpieces yuav tsum tau ceev nrooj clamped kom tsis txhob muaj zaj duab xis hauv zos vim tsis muaj kev sib cuag thaum lub sij hawm anodization. Clamping yuav tsum tiv thaiv fixture shielding los xyuas kom meej tag nrho kev sib cuag ntawm workpiece nto thiab electrolyte. Rau kev sib txuas hauv Circuit Court, lub workpiece ua haujlwm ua tus anode. Rau cov xim tsis sib xws, hloov cov cathode nrog titanium phaj thiab tuav lub cathode -anode cheeb tsam piv ntawm 1: 1 los txhim kho cov yeeb yaj kiab sib xws.

2. Kev xaiv electrolyte
Sulfuric acid-raws li:Fast film tsim, tsis muaj xim thiab pob tshab zaj duab xis, nruab nrab corrosion kuj, tus nqi qis. Haum rau cov khoom siv kho kom zoo nkauj, cov khoom siv hauv tsev, thiab cov khoom siv insulating.
Oxalic acid -raws li:Dense zaj duab xis, zoo heev corrosion kuj. Xim tuaj yeem hloov kho los ntawm golden daj mus rau xiav, ntsuab, lossis ntshav los ntawm kev tswj qhov hluav taws xob. Haum rau aerospace Cheebtsam thiab precision hluav taws xob qhov chaw.
Phosphoric acid-chromic acid-raws li: Kev tiv thaiv corrosion siab heev, haum rau hnyav corrosive ib puag ncig xws li marine thiab tshuaj industries. Vim yog cov tshuaj lom ntawm chromic acid, yuav tsum muaj kev tswj hwm ib puag ncig nruj, ua rau muaj kev txwv tsis pub siv.
Ib puag ncig tus phooj ywg hom:Fluoride-dawb, chromium-dawb, tsis muaj tshuaj lom, kho cov kua khib nyiab yooj yim. Multicolor coloring ua tiav los ntawm kev hloov pauv voltage, nrog rau zaj duab xis adhesion zoo. Haum rau siab -kawg teb xws li cov cuab yeej kho mob thiab zaub mov- tiv tauj cov khoom.

3. Txheej txheem Parameter Control
Voltage:Qhov hluav taws xob kuj txiav txim siab cuam tshuam xim xim- qhov hluav taws xob ntau dua ua rau cov yeeb yaj kiab tuab thiab ntau xim sib txawv.
Tam sim no ceev:Tsis tshua muaj tam sim no ua rau qeeb zaj duab xis tsim, thaum tam sim no ntau dhau ua rau hauv zos overheating, ua rau cov yeeb yaj kiab tawg thiab ablation.
Kub:Sodium bicarbonate-raws li ib puag ncig tus phooj ywg electrolytes yuav tsum tau tswj qhov kub thiab txias ntawm 25 ~ 45℃los tiv thaiv electrolyte decomposition.
Sijhawm:Cov pa 10-60min, Ib puag ncig tus phooj ywg electrolytes pab tsim cov yeeb yaj kiab sai hauv tsuas yog 5-30s.

Ncej - ntxuav:Tiv thaiv zaj duab xis corrosion thiab discoloration thiab xyuas kom meej sealing zoo.
Kev kho sealing:Sau zaj duab xis pores los txhim kho compactness thiab tiv thaiv kev ua haujlwm. ① Boiling dej sealing ② ntsev tov sealing
Kev ziab:Qhuav lub workpiece tom qab sealing kom tsis txhob yellowing los yog pwm loj hlob los ntawm residual ya raws. Rau cov khoom siv kho kom zoo nkauj, maj mam txhuam nrog cov ntaub paj rwb huv tom qab ziab kom zoo dua ci.

Piv nrog cov thev naus laus zis kho saum npoo zoo li electroplating thiab txau, cov yeeb yaj kiab anodized oxide nthuav tawm muaj zog adhesion rau lub substrate, superior corrosion kuj, thiab cov txheej txheem siab controllability. Functional customization tuaj yeem ua tiav los ntawm kev hloov pauv. Feem ntau cov electrolytes yog recyclable, muab qhov tseem ceeb ntawm ib puag ncig zoo.
