Platinized titanium anodes synopsis
Titanium/Tantalum/Niobium-based platinum plated anode process, inoshandisa electroplating kana brush plating kana kusanganisira coating process, chitarisiko chinopenya chena sirivha, ine hunhu hweanode discharge yakakura density uye hupenyu hurefu hwebasa.
Platinized titanium anodes synergistically inosanganisa inofarirwa electrochemical maficha eplatinamu (Pt) nekushomeka kwekuora uye mamwe maitiro etitanium. Iwo maanode anowanzo gadzirwa ne electrochemical deposition yeakatetepa simbi yeplatinamu kana maokisi eplatinamu pane titanium substrate. Aya anode anoshanda seinert anode ane kusimba kwepamusoro uye anofarirwa nekuti anoramba asinganyungudika mumaelectrolyte akajairika.
Platinamu isimbi yakakosha inozivikanwa neyakasiyana yakasarudzika hunhu, kusanganisira
- High resistance kune ngura
- Kupokana kune oxidation
- High magetsi conductivity
- Kugona kuita secatalyst
- Kugadzikana kwemakemikari yakakwirira
- Kugona kugadzira kupera kwakanaka
Iyo yakaderera yekushandisa mwero inotsigirwa neakakwira magetsi conductivity inoita kuti platinamu ive chinhu chinodiwa anode. Asi nekuda kwekudhura kwayo, chikamu chitete chete cheplatinamu chinowanzo kuputirwa pane zvakasiyana-siyana zvisingadziviriri zvinhu zvakaita setantalum (Ta), niobium (Nb) kana titanium (Ti) kutora mukana weaya maficha akanaka.
Platinized titanium anodes processing tekinoroji
Ne electroplating kana bhurashi plating process (kusanganisira platinum coating sintering kugadzira process) iyo platinamu simbi pane titanium (tantalum, niobium), inoumbwa simbi yekuputira inogona zvakare kugadzirwa pane substrate. Musanganiswa uyu une titanium simbi, platinamu, okisidi yetitanium uye simbi inosanganiswa yetitanium neplatinamu.
platinamu yekunamira sintering yekugadzira maitiro: isu tinogadzira platinized titanium anode nekutora kupisa kwekuora maitiro kuti tiwane dense kupfeka-inodzivirira layer yeplatinum yekupotera. Iyo anode yepamusoro inogadziridzwa kuti ivandudze kunamatira kweplatinamu uye kuvandudza zvakanyanya kufanana kwehukukutu hwekufukidzira, zvakare kuderedza iyo coating porosity ichipa yakakura acid kuramba kune anode. , Iyo nzira yekupisa inobata iyo yakasanganiswa coating inoburitsa shanduko mumakemikari anoumbwa uye morphology inovandudza ayo electrochemical properties. Iyi platinamu yakavharwa titanium anode inogona kugadzirwa kuita bar, tsvimbo, shizha, mesh uye imwe yakagadziridzwa chimiro kuti isangane nezvido zvako zvakakosha.
Kemikari maitiro eplatinized titanium anodes
Platinamu inofarirwa pane anode yekunze nekuti inoshingirira mukuora uye inokwanisa kuona kuyerera kwazvino muma electrolyte media akawanda pasina kutungamirira kukugadzirwa kwe insulating layer pachayo. Nekuti haina corrode, haiburitse zvigadzirwa zvekuora uye nekudaro mwero wekushandisa wakadzikira.
Platinamu inonyungudika mune yakasanganiswa munyu uye asidhi, asi inonyungudika mu aqua regia. Iko hakuna njodzi yehydrogen embrittlement. (Unogona kudzidza nezve hydrogen embrittlement munyaya inonzi An Introgen to Hydrogen Embrittlement.) Ndiyo imwe yemasimbi mashoma asingawanzo nyatso ramba ma chlorides emvura yegungwa.
Titanium inoratidza kuramba kwakanaka kune nharaunda yegungwa (mvura yegungwa kunyanya). Iyo haina kuita neyakaomeswa (80%) mhinduro dzesimbi chlorides. Nekudaro, inogona kurwiswa nehydrofluoric acid (HF) uye inopisa hydrochloric acid (HCl) yemazinga akakwira. Kunyange hydrogen peroxide uye inopisa nitric acid inogona kurwisa titanium. Oxidizing agents kazhinji haarwise titanium nekuti inogadzira inodzivirira oxide coating. Zvisinei, zvinhu zvisina-oxidizing zvakadai sesulfuric acid (pamusoro pe5% concentration) uye phosphoric acid (pamusoro pe30%) inogona kurwisa titanium. Kubva pane hydrogen embrittlement point yekuona, titanium inofamba zvirinani pane tantalum seanode zvinhu.
Zvakanakira platinized titanium anodes
Platinamu ine zvakanakira zve electrochemical inertness, mechanical simba, workability uye yakanaka magetsi conductivity. Nekudaro, inodhura zvisingaite. Kuvandudzwa kweplatinum patitanium neplatinum patantalum (yakapfava pamwe chete neyakavharwa) zvinhu zvakavhura mukana wekushandisa izvi kune anode zvinhu zvekupedzisa simbi uye cathodic dziviriro masisitimu mune zvakakosha kunyorera.
Kana ichishandiswa kune anodhi mune aqueous media semvura yegungwa, iyo titanium inoumba yakagadzikana layer ye insulating oxide film pamusoro iyo yakagadzikana pazasi peimwe breakdown voltage, nokudaro ichidzivirira kuyerera ikozvino pakati peaqueous media neanode. Munharaunda yegungwa, iyo oxide yakaumbwa patitanium inokwanisa kumira 12 volts, kupfuura iyo inodzivirira inodzivirira inoputsika uye ikozvino kuyerera kunotanga kuita ngura.
Zvinoumba platinized titanium anodes
- platinized titanium anodes geometry inoramba iripo nekufamba kwenguva.
- Kuchengetedza magetsi.
- High corrosion resistance.
- High dimensional kugadzikana uye mutoro wekudzivirira.
- Kukwirira kwepamusoro kwekunamatira kwesimbi yakakosha yekuputira.
- Kuvandudza kupikisa kukurwisa asidi.
- Yakawedzera throughput pamwe yakaderedzwa plating nguva.
- Huremu huremu (kunyanya mesh grid anode).
- Upenyu hurefu hwekushanda; kuchengetedza-isina.
- Hupenyu hurefu hwesevhisi pasi pehurefu hwazvino mukuwanda muacidic mhinduro.
- Gadzira chimiro chakaoma cheanode.
- Kupokana nekuderedzwa kwe interface nemadhipoziti.
Kushandiswa kweplatinized titanium anodes
- Horizontal plating, pulse plating;
- Precious metal electroplating - eg Au, Pd, Rh uye Ru mabhati;
- Non-ferrous metal electroplating - eg Ni, Cu, Sn, Zn uye kwete-fluoride Cr mabhati;
- Yakadhindwa redunhu mapuranga electroplating;
- Yakafadzwa Iyezvino Cathodic Dziviriro.
Tinogona kugadzira platinized titanium (kana Ta, Nb) anode yemahwendefa, mesh, machubhu, kana kugadziridzwa zvinoenderana nezvinodiwa nevatengi.
