Titanium cathode daim hlau tau nce dav siv nyob rau hauv siab -kawg electrolysis txheej txheem vim lawv zoo corrosion kuj, zoo mechanical stability, thiab controllable electrochemical zog. Txhawm rau kom ua tiav lawv cov txiaj ntsig zoo hauv kev tsim vaj tsev, ntau yam txuj ci tseem ceeb yuav tsum tau ua tiav hauv kev xaiv cov khoom siv, kev kho saum npoo, sib dhos thiab kev sib txuas, thiab kev ua haujlwm thiab kev saib xyuas kom ruaj khov, kev ua haujlwm ntev, thiab txhim kho tag nrho cov txheej txheem.
Nyob rau hauv kev xaiv cov khoom thiab pretreatment theem, tus yuam sij yog kom raug raws li qib titanium thiab specifications raws li hom electrolyte thiab ua hauj lwm tej yam kev mob. Kev lag luam ntshiab titanium yog haum rau feem ntau acidic ib puag ncig, thaum nyob rau hauv fluorine -muaj, muaj zog oxidizing, los yog siab -kub tshuab, titanium-raws li txheej cov ntaub ntawv nrog ntxiv precious hlau oxides xws li ruthenium thiab iridium yog preferable los txhim kho catalytic kev ua si thiab corrosion kuj. Dej-txo cov txheej txheem laser lossis plasma yuav tsum zoo dua rau kev txiav kom tsis txhob muaj cov nplej coarsening lossis nce hardness hauv tshav kub- thaj tsam cuam tshuam; Kev ntxhov siab raws sij hawm-relief annealing tom qab tsim tuaj yeem tiv thaiv kev ntxhov siab los ntawm kev ua rau microcracks lossis warping thaum lub sij hawm electrolysis tom qab.
Kev kho deg yog ib qho tseem ceeb ntawm kev txiav txim siab tus cwj pwm electrochemical ntawm titanium cathode daim hlau. Txawm hais tias yooj yim mechanical polishing tuaj yeem txhim kho qhov chaw tiav, nyob rau hauv cov xwm txheej ntawm corrosion los yog siab ceev tam sim no, nws yuav tsum tau ua ke nrog cov tshuaj passivation los yog anodizing kom thicken thiab stabilize cov oxide zaj duab xis, yog li txhim kho nws tus kheej - kho muaj peev xwm. Rau cov txheej txheem tsom rau kev ua haujlwm siab tam sim no, txheej txheej catalytic nrog qis hydrogen evolution overpotential tuaj yeem npaj rau ntawm qhov chaw kom txo qis kev cuam tshuam sab thiab nce cov hlau tso nyiaj. Daim ntawv thov txheej yuav tsum muaj kev tswj xyuas nruj tshaj qhov sib xws thiab adhesion; Nws raug nquahu kom siv kev sib xyaw ua ke ntawm ntau yam nyias nyias - txheej txheej txheej thiab siab - kub sintering kom tsis txhob pinholes, tev, thiab lwm yam tsis xws luag los ua cov ntsiab lus hauv cheeb tsam corrosion.
Kev sib dhos thiab kev sib txuas cov txheej txheem qhia txog ob qho tib si qis impedance thiab kev tiv thaiv ntawm galvanic corrosion. Kev sib txuas ncaj qha ntawm titanium thiab tooj liab busbars raug cuam tshuam rau cov teebmeem galvanic; Nws raug nquahu kom siv titanium- cov phaj hloov pauv tooj liab lossis ntxiv cov khoom siv insulating rau qhov sib txuas ntawm qhov chaw, thiab siv lub zog torque-tswj bolts los xyuas kom nruj thiab sib cuag. Rau loj- qhov loj lossis ntau- taw tes cathode daim hlau, ntau- taw tes sib txuas tuaj yeem siv los faib cov khoom thauj tam sim no thiab txo qhov kev pheej hmoo ntawm qhov kub thiab txias hauv cheeb tsam. Tsis tu ncua xyuas qhov xwm txheej ntawm cov kab hluav taws xob tiv tauj thiab tu tam sim ntawd cov oxide zaj duab xis thiab cov khoom paug tuaj yeem ua kom tsis muaj kev sib cuag.
Tus yuam sij rau kev ua haujlwm thiab kev saib xyuas yog nyob rau hauv kev tsim kom muaj kev soj ntsuam xyuas thiab kho cov txheej txheem. Txawm hais tias muaj kev tiv thaiv zoo tshaj plaws ntawm titanium cathode daim hlau, oxide zaj duab xis tseem tuaj yeem raug puas tsuaj los ntawm kev tso nyiaj lossis kev puas tsuaj thaum lub sijhawm ua haujlwm ntev -. Kev ntxuav cov kua qaub tsis tu ncua lossis kev ntxuav electrolytic, ua ke nrog re-passivation, yog qhov tsim nyog los kho qhov kev ncaj ncees ntawm zaj duab xis. Siv cov kev soj ntsuam hauv online txhawm rau taug qab cov kev hloov pauv ntawm lub xov tooj ntawm tes, kev faib tawm ceev tam sim no, thiab cov khoom siv electrolyte tso cai rau kev txheeb xyuas ntxov ntawm kev tsis txaus ntseeg thiab kev hloov pauv ntawm cov txheej txheem, tiv thaiv kev ua tsis tiav sai.
Tsis tas li ntawd, lub phaj tsim thiab qhov chaw saum npoo yuav tsum tau hloov kho kom yooj yim rau kev siv sib txawv. Piv txwv li, nyob rau hauv precious hlau rov qab, lub hom phiaj yuav tsum yog nyob rau hauv tsawg leaching thiab siab huv si; nyob rau hauv kev ua haujlwm electroplating, qhov tseem ceeb yuav tsum yog nyob rau niaj hnub kev faib khoom; thiab hauv kev npaj cov khoom siv hluav taws xob, qhov tseem ceeb yuav tsum yog nyob rau saum npoo smoothness thiab impurity tswj. Kev sib koom ua ke ntawm titanium cathode daim hlau nrog kev siv lub tshuab ntxuav thiab cov cuab yeej ntse tuaj yeem txhim kho kev lag luam kev ntseeg siab thiab kev tswj xyuas kom zoo.
Hauv cov ntsiab lus, kev siv tau zoo ntawm titanium cathode daim hlau yog nyob ntawm ntau cov txheej txheem, suav nrog kev xaiv cov khoom siv, kev kho kom zoo nkauj, qis- kev sib txuas tsis sib xws, thiab kev saib xyuas kev tshawb fawb. Mastering thiab nkag siab txog kev siv cov tswv yim no tsis tsuas yog ua kom muaj txiaj ntsig zoo ntawm titanium xwb tab sis kuj muab kev lav zoo rau kev ruaj ntseg, kev lag luam, thiab kev loj hlob ntsuab ntawm cov txheej txheem electrolysis.
