platinized titaniyamu anodes synopsis
Titaniyamu / Tantalum / Niobium-based platinamu yokutidwa anode ndondomeko, pogwiritsa ntchito electroplating kapena burashi plating kapena kuphatikizapo ❖ kuyanika ndondomeko, maonekedwe ndi owala siliva woyera, ndi makhalidwe a anode kutulutsa lalikulu kachulukidwe panopa ndi moyo wautali utumiki.
Platinized titaniyamu anodes synergistically kuphatikiza yabwino electrochemical mbali platinamu (Pt) ndi kukana dzimbiri ndi makhalidwe ena a titaniyamu. Ndi ma anode omwe amapangidwa ndi electrochemical deposition ya chitsulo chochepa kwambiri cha platinamu kapena ma oxide a platinamu pagawo la titaniyamu. Ma anodewa amagwira ntchito ngati anode okhazikika komanso olimba kwambiri ndipo amakondedwa chifukwa amakhala osasungunuka m'ma electrolyte wamba.
Platinamu ndi chitsulo chamtengo wapatali chomwe chimadziwika ndi mawonekedwe ake apadera, kuphatikiza
- High kukana dzimbiri
- Kukana kwa oxidation
- High magetsi madutsidwe
- Kutha kuchita ngati chothandizira
- Kukhazikika kwamphamvu kwamankhwala
- Kutha kupanga kumaliza kwabwino kwambiri
Kutsika kwapang'onopang'ono kogwiritsidwa ntchito mothandizidwa ndi kuchuluka kwamagetsi kumapangitsa platinamu kukhala chinthu chokondedwa cha anode. Koma chifukwa cha kukwera mtengo kwake, platinamu yopyapyala yokha ndiyomwe imakutidwa pazinthu zosiyanasiyana zolimbana ndi dzimbiri monga tantalum (Ta), niobium (Nb) kapena titaniyamu (Ti) kuti agwiritse ntchito zinthu zabwinozi.
Platinized titaniyamu anodes processing luso
Mwa electroplating kapena burashi plating ndondomeko (kuphatikiza platinamu ❖ kuyanika sintering ndondomeko) platinamu zitsulo pa titaniyamu (tantalum, niobium), ndi gulu zitsulo ❖ kuyanika akhoza kupangidwa pa gawo lapansi. Gulu ili lili ndi titaniyamu zitsulo, platinamu, oxides wa titaniyamu ndi zitsulo mankhwala titaniyamu ndi platinamu.
platinamu ❖ kuyanika sintering ndondomeko: timapanga platinamu anode platinamu potengera njira kuwola matenthedwe kupeza wosanjikiza wosamva kuvala nsanjika wa platinamu. Manode pamwamba amasinthidwa kuti apititse patsogolo kumamatira kwa platinamu komanso kuti apititse patsogolo kufanana kwa makulidwe a ❖ kuyanika, komanso kuchepetsa kukhazikika kwa ❖ kuyanika kumapereka kukana kwakukulu kwa asidi ku anode. , Njira ya kutentha yochizira ❖ kuyanika kophatikizana imapanga kusintha kwa mankhwala ndi morphology yomwe imapangitsa kuti ma electrochemical apangidwe bwino. Titanium anode iyi yokhala ndi platinamu imatha kupangidwa kukhala bar, ndodo, pepala, mauna ndi mawonekedwe ena osinthika kuti akwaniritse zosowa zanu zapadera.
Chemical khalidwe la platinized titaniyamu anode
Platinamu imakondedwa pakunja kwa anode chifukwa imalimbana kwambiri ndi dzimbiri ndipo imatha kuwonetsetsa kuti ma electrolyte akuyenda pakali pano popanda kupangitsa kuti pawokha pakhale chotchingira chotchinga. Chifukwa sichita dzimbiri, sipanga dzimbiri ndipo chifukwa chake anthu amadya ndi otsika kwambiri.
Platinamu imalowetsedwa mumchere wosakanikirana ndi ma acid, pomwe imasungunuka mu aqua regia. Palibe chiopsezo cha hydrogen embrittlement. (Mutha kuphunzira za hydrogen embrittlement m’nkhani yakuti An Introduction to Hydrogen Embrittlement.) Ndi imodzi mwa zitsulo zosowa kwambiri zimene zimalimbana bwino ndi ma chloride a m’madzi a m’nyanja.
Titaniyamu imasonyeza kukana bwino kwa malo a m'nyanja (makamaka madzi a m'nyanja). Sichichita ndi zitsulo (80%) zothetsera zitsulo zachitsulo. Komabe, imatha kugwidwa ndi hydrofluoric acid (HF) ndi hot hydrochloric acid (HCl) yokhazikika kwambiri. Ngakhale hydrogen peroxide ndi nitric acid yotentha imatha kuwononga titaniyamu. Oxidizing agents nthawi zambiri samalimbana ndi titaniyamu chifukwa amapanga zokutira zoteteza oxide. Komabe, zinthu zopanda oxidizing monga sulfuric acid (pamwamba pa 5% concentration) ndi phosphoric acid (pamwamba pa 30%) zimatha kuwononga titaniyamu. Kuchokera pamawonekedwe a hydrogen embrittlement, titaniyamu imayenda bwino kuposa tantalum ngati chinthu cha anode.
Ubwino wa platinized titaniyamu anode
Platinamu ili ndi maubwino a electrochemical inertness, mphamvu zamakina, kugwirira ntchito komanso kuyendetsa bwino kwamagetsi. Komabe, ndi okwera mtengo kwambiri. Chitukuko cha platinamu pa titaniyamu ndi platinamu pa tantalum (yokutidwa komanso yokutidwa) yatsegula kuthekera kogwiritsa ntchito izi pazinthu za anode zomalizitsa zitsulo ndi machitidwe achitetezo a cathodic muzovuta kwambiri.
Pamene ntchito anodes mu amadzimadzi TV monga madzi a m'nyanja, titaniyamu ndi kupanga khola wosanjikiza wa insulating okusayidi filimu pamwamba kuti ndi khola pansi ena kusweka voteji, motero kuteteza otaya panopa pakati pa amadzimadzi TV ndi anode. M'madzi am'madzi, oxide yomwe imapangidwa pa titaniyamu imatha kupirira ma volts 12, kupitilira pomwe chotchinga chotchinga chimasweka ndipo kutuluka kwapano kumayambitsa dzimbiri.
Mawonekedwe a platinized titaniyamu anode
- platinized titanium anodes geometry imakhalabe nthawi zonse.
- Kupulumutsa mphamvu.
- High dzimbiri kukana.
- Kukhazikika kwapamwamba kwambiri komanso kukana katundu.
- Kumamatira kwakukulu kwa zokutira zamtengo wapatali zachitsulo.
- Kupititsa patsogolo kukana kwa asidi.
- Kuchulukirachulukira ndi kuchepetsedwa nthawi zomata.
- Kulemera kopepuka (makamaka ma mesh grid anode).
- Moyo wautali wogwira ntchito; wopanda kukonza.
- Moyo wautali wautumiki pansi pa kachulukidwe kakang'ono kamakono mumayankho a acidic.
- Pangani mawonekedwe ovuta a anode.
- Kukana kuwonongeka kwa mawonekedwe ndi madipoziti.
Kugwiritsa ntchito platinized titaniyamu anode
- Horizontal plating, pulse plating;
- Electroplating yachitsulo yamtengo wapatali - monga mabafa a Au, Pd, Rh ndi Ru;
- Ma electroplating achitsulo osagwiritsa ntchito chitsulo - mwachitsanzo, Ni, Cu, Sn, Zn ndi mabafa opanda fuloridi a Cr;
- Zosindikizidwa matabwa a dera electroplating;
- Chitetezo Chamakono cha Cathodic.
Titha kupanga platinized titaniyamu (kapena Ta, Nb) anode mbale, mauna, machubu, kapena makonda malinga ndi zofuna za makasitomala.
