Platinized titanium anodes synopsis
Titanium/Tantalum/Niobium-ku-saleysan platinum-ku-saleysan habka anode-ga, iyadoo la adeegsanayo koronto-samaynta ama dahaaridda burushka ama ay kujirto habka daahan, muuqaalku waa caddaan cad oo dhalaalaya, oo leh astaamaha dheecaanka anode-ka weyn ee cufnaanta hadda iyo nolosha adeegga dheer.
Platinized titanium anodes synergistically isku daraa sifooyinka korantada wanaagsan ee platinum (Pt) iyo caabbinta daxalka iyo sifooyinka kale ee titanium. Waxay yihiin anodes sida caadiga ah ay soo saarto fadhiisinta kiimikooyinka korantada ee lakabka aadka u khafiifsan ee birta platinum ama oksaydhka platinum ee dulsaar substrate titanium. Anodes-yadani waxay u shaqeeyaan sidii anodes aan shaqaynayn oo leh adkeysi sare waxaana la door bidaa sababtoo ah waxay ku sii milmayaan korantada caadiga ah.
Platinum waa bir qaali ah oo loo yaqaan sifooyin wanaagsan oo gaar ah, oo ay ku jiraan
- Iska caabbinta sare ee daxalka
- Iska caabinta oksidation
- Dhaqdhaqaaq koronto oo sarreeya
- Kartida u dhaqmida sida kicinta
- Degenaansho kiimikaad oo sarreeya
- Kartida soo saarista dhammayn wanaagsan
Heerka isticmaalka hooseeya ee ay taageerto korantada sare waxay ka dhigaysaa platinum walax anode la door bidayo. Laakiin qiimaha sare ee uu leeyahay, kaliya lakab khafiif ah oo platinum ah ayaa sida caadiga ah lagu dhejiyay walxo kala duwan oo u adkaysta daxalka sida tantalum (Ta), niobium (Nb) ama titanium (Ti) si looga faa'iidaysto sifooyinkan wanaagsan.
Tiknooloojiyada farsamaynta ee platinized titanium anodes
Ku dhejinta korantada ama habka dahaadhidda burushka (oo ay ku jiraan habka wax soo saarka daahan platinum) biraha platinum ee titanium (tantalum, niobium), daahan macdan ah oo isku dhafan ayaa sidoo kale lagu soo saari karaa substrate-ka. Isku-dhafkan wuxuu ka kooban yahay birta titanium, platinum, oxides of titanium iyo xeryahooda macdan ee titanium iyo platinum.
habka wax soo saarka daahan platinum sintering: waxaan soo saara platinized titanium anode annagoo qaadanayna habka duminaysaa kulaylka si aad u hesho lakabka cufan u adkaysta ee daahan platinum. Dusha anode-ka ayaa wax laga beddelay si loo hagaajiyo adhesion of platinum iyo in si weyn loo hagaajiyo lebbiska dhumucda daahan, sidoo kale la dhimo porosity daahan siin caabbinta acid weyn anode ah. , Habka kulaylka lagu daaweynayo daahan isku-dhafka ah ayaa soo saara isbeddel ku yimaada habka kiimikada iyo qaab-dhismeedka kaas oo hagaajinaya sifooyinka korantada. Titanium anode-ka dahaarka leh ee platinum waxa lagu farsamayn karaa baararka, usha, xaashida, mesh iyo qaab kale oo la habeeyey si loo daboolo baahiyahaaga gaarka ah.
Dabeecadda kiimikada ee anodes titanium platinized
Platinum ayaa la doorbidaa dusha sare ee anode-ka sababtoo ah aad ayey ugu adkeysaneysaa daxalka waxayna xaqiijin kartaa socodka hadda ee inta badan warbaahinta elektrolytka iyada oo aan loo horseedin samaynta lakabka daboolka laftiisa. Sababtoo ah ma daxaloobay, ma soo saaro wax soo saarka daxalka sidaas darteed heerka isticmaalka ayaa aad u hooseeya.
Platinum waa mid aan firfircoonayn milix iyo asiidh isku dhafan, halka ay ku milmeen aqua regia. Ma jirto wax khatar ah oo ku iman kara qallafsanaanta hydrogen. (Waxaad ka baran kartaa wax ku saabsan embrittlement hydrogen-ka maqaalka Hordhac ku saabsan Embrittlement Hydrogen.) Waa mid ka mid ah biraha dhifka ah ee sida fiican isaga caabiya koloridhiyada biyaha badda.
Titanium waxay muujinaysaa iska caabin macquul ah oo wanaagsan deegaanka badda (gaar ahaan biyaha badda). Kuma falceliso xalalka isku-uruursan (80%) ee chlorides-macdan. Si kastaba ha ahaatee, waxay u nugushahay in lagu weeraro hydrofluoric acid (HF) iyo aashitada kulul ee hydrochloric (HCl) ee xaddi sare. Xitaa hydrogen peroxide iyo nitric acid kulul waxay weerari karaan titanium. Waxyaalaha oksaydhisku sida caadiga ah ma weeraraan titanium sababtoo ah waxay si sahal ah u samaysaa dahaar oksaydh ilaalin ah. Si kastaba ha ahaatee, walxaha aan oksaydhiyeyaasha ahayn sida sulfuric acid (ka sarreeya 5% diiradda) iyo fosfooraska (ka sarreeya 30%) waxay weerari karaan titanium. Marka laga eego dhinaca aragtida ebrittlement hydrogen, qiimaha titanium wuu ka fiican yahay tantalum sida walxo anode ah.
Faa'iidooyinka anodes titanium platinized
Platinum waxay leedahay faa'iidooyinka la'aanta korantada, xoogga farsamada, karti-shaqsiyeedka iyo korantada wanaagsan. Si kastaba ha ahaatee, aad bay qaali u tahay. Horumarinta platinum ee titanium iyo platinum ee tantalum (dahaaran iyo sidoo kale cladded) alaabta ayaa furay suurtogalnimada isticmaalka kuwan alaabta anode ee dhamaystirka birta iyo hababka ilaalinta cathodic ee codsiyada muhiimka ah.
Marka loo isticmaalo anodes ee warbaahinta aqueous sida biyaha badda, titanium wuxuu sameeyaa lakab xasilan oo film oksaydh insulating on dusha kaas oo xasilloon ka hooseeya danab burburay gaar ah, sidaas darteed ka hortagga socodka hadda u dhexeeya warbaahinta aqueous iyo anode ah. Deegaanka badda, oksaydhka ka sameysan titanium wuxuu awood u leeyahay inuu u adkeysto 12 volts, taas oo ka baxsan xannibaadda xannibaadda ayaa jebisa oo socodka hadda socdaa wuxuu bilaabaa habka daxalka.
