Ntụle nke titanium anodes nke platinized
Titanium / Tantalum / Niobium dabeere platinum plated anode usoro, ọ na-eji electroplating ma ọ bụ ahịhịa plating ma ọ bụ gụnyere mkpuchi usoro, ọdịdị na-egbuke egbuke ọlaọcha na-acha ọcha, na e ji mara nnukwu anode ikwasa njupụta ugbu a na ogologo ndụ ọrụ.
Platinized titanium anodes synergistically jikọtara mma electrochemical atụmatụ nke platinum (Pt) na corrosion eguzogide na ndị ọzọ e ji mara titanium. Ha bụ anodes nke a na-emepụtakarị site na ntinye nke electrochemical nke oyi akwa platinum dị gịrịgịrị ma ọ bụ oxides nke platinum n'ime mkpụrụ nke titanium. Ndị a anodes na-arụ ọrụ dị ka inert anodes na elu anwụ ngwa na-ahọrọ n'ihi na ha na-anọgide na-adịghị soluble na nkịtị electrolytes.

Nkà na ụzụ nhazi nke titanium anodes platinized
Site na electroplating ma ọ bụ brush plating usoro (gụnyere platinum mkpuchi sintering nhazi usoro) na platinum metal na titanium (tantalum, niobium), a mejupụtara ọla mkpuchi nwekwara ike na-emepụta na mkpụrụ. Ihe mejupụtara a nwere ọla titanium, platinum, oxides nke titanium na ogige ọla nke titanium na platinum.
Platinum mkpuchi sintering usoro mmepụta: anyị na-arụpụta platinized titanium anode site n'inwe thermal decomposition usoro iji nweta akwa akwa mkpuchi na-eguzogide platinum.

Omume kemịkalụ nke platinized titanium anodes
A na-ahọrọ Platinum n'elu elu nke anode n'ihi na ọ na-eguzogide corrosion nke ukwuu ma nwee ike hụ na ọ na-eru ugbu a n'ọtụtụ mgbasa ozi electrolyte na-edugaghị na nhazi nke mkpuchi mkpuchi n'onwe ya. N'ihi na ọ naghị emebi emebi, ọ naghị emepụta ngwaahịa corrosion na ya mere ọnụego oriri na-adị ala.
Platinum enweghị ike ịbanye na nnu na acids agwakọtara, ebe ọ na-agbaze na aqua regia. Ọ dịghị ihe ize ndụ nke hydrogen ebrittlement. (Ị nwere ike ịmụta banyere embrittlement hydrogen na isiokwu bụ Okwu Mmalite nke Hydrogen Embrittlement.) Ọ bụ otu n'ime ọla ole na ole na-adịghị ahụkebe na-eguzogide chlorides nke mmiri oké osimiri n'ụzọ zuru oke.
Titanium na-egosi nguzogide dị mma na gburugburu mmiri (mmiri mmiri karịsịa). Ọ naghị emeghachi omume site na ntinye uche (80%) ngwọta nke ọla chlorides. Otú ọ dị, ọ dị mfe ịwakpo hydrofluoric acid (HF) na ọkụ hydrochloric acid (HCl) nke mkpokọta dị elu. Ọbụna hydrogen peroxide na nitric acid na-ekpo ọkụ nwere ike ịwakpo titanium.

Uru nke platinized titanium anodes
Platinum nwere uru nke inertness electrochemical, ike n'ibu, ịrụ ọrụ na ezigbo ọkụ eletrik. Otú ọ dị, ọ bụ prohibitively ọnụ. Mmepe nke platinum na titanium na platinum na tantalum (plated yana cladded) emeghewo ohere nke iji ihe ndị a maka ihe anode maka ịmecha ígwè na usoro nchebe cathodic na ngwa dị egwu.
Mgbe eji maka anodes na aqueous media dị ka oké osimiri, titanium na-etolite a kwụsiri ike oyi akwa nke insulating oxide film n'elu nke kwụsiri ike n'okpuru a ụfọdụ mmebi voltaji, si otú na-egbochi a ugbu eruba n'etiti aqueous media na anode. Na gburugburu mmiri, oxide e guzobere na titanium na-enwe ike iguzogide 12 volts, karịa nke ihe mgbochi mkpuchi na-akụda ma ugbu a na-asọba na-amalite usoro mmebi.
