Hoʻolauna pōkole

Hoʻokomo ʻia nā huahana alumini anodized a i ʻole alumini alumini i ka hopena electrolyte no ka mālama ʻana i ka galvanization, a ʻo ke kaʻina hana o ka hana ʻana i ke kiʻi alumini oxide ma luna o ka ʻili e ka electrolysis i kapa ʻia he mālama anodized o ka alumini a me ka alumini alumini.Ma hope o ka hoʻomaʻamaʻa anodic oxidation, hiki i ka ʻili alumini ke hana i kekahi mau microns - mau haneli mau microns o ke kiʻi ʻoniʻoni.

ʻO ke kumumanaʻo o ka anodic oxidation o ka alumini ke kumu o ka hydroelectrolysis. Ke hala ke ʻano uila, hiki mai ka hopena:
Ma ka cathode, hoʻokuʻu ʻia ʻo H2 penei: 2H + + 2e → H2
Ma ka anode, 4OH-4E → 2H2O + O2, ʻo ka oxygen precipitated ʻaʻole wale ka oxygen molecular (O2), akā ʻo ka oxygen atomic (O) a me ka oxygen ionic (O-2), i hōʻike pinepine ʻia e like me ka oxygen mole i ka hopena.
Ma ke ʻano he anode, ua hoʻoneʻe ʻia ka aluminika e ka ua o ka oxygen ma luna o ia mea e hana i kahi kiʻiʻoniʻoni Al2O3 me ka wai ʻole: 2AI + 3[O] = AI2O3 + 1675.7kj Pono e kuhikuhi ʻia ʻaʻole pili nā oxygen a pau me ka alumini, akā kekahi. ua hookaheia ma ke ano o ke kinoea.
Ua hoʻohana nui ʻia ka oxidation anodic i ka ʻoihana, e like mealumini CNC machining ʻāpana.Ma hope o ka anodized, hiki i nā ʻāpana mīkini CNC alumini ke loaʻa ka hiʻohiʻona kupaianaha a me ka mana antioxidant maikaʻi.

Nui nā ala e lepili ai i nā inoa like ʻole, hiki ke hōʻuluʻulu ʻia penei:
E like me ke ʻano o kēia manawa, hiki ke hoʻokaʻawale ʻia i ka anodizing o kēia manawa, ka anodizing o kēia manawa, a me ka anodizing pulsed o kēia manawa, hiki ke hoʻopōkole i ka manawa hana e hiki ai i ka mānoanoa i koi ʻia, ʻo ka papa kiʻiʻoniʻoni he mānoanoa a me ke ʻano a me ka paʻa, a me ke kūpaʻa corrosion. ua hoʻomaikaʻi nui ʻia.
Wahi a ka electrolyte: sulfuric acid, oxalic acid, chromic acid, mixed acid and organic sulfonic acid solution of natural color anodic oxidation.
E like me nā waiwai o ka kiʻiʻoniʻoni, hiki ke hoʻokaʻawale ʻia i ke kiʻiʻoniʻoni maʻamau, ke kiʻiʻoniʻoni paʻakikī (kiʻiʻoniʻoni mānoanoa), ka kiʻiʻoniʻoni porcelain, ka papa hoʻololi mālamalama a me ka papa pale o ka hana semiconductor.
ʻO keʻano anodizing o ka waikawa electrosulfuric i kēia manawa ka mea i kaulana loa, no ka mea, he kūpono ia no ka anodizing aluminika a me ka hapa nui o nā alumini alumini. ʻAʻole waihoʻoluʻu ka papa kiʻiʻoniʻoni, me ka mana adsorption ikaika a me ka waihoʻoluʻu maʻalahi. ʻO ka uila hana haʻahaʻa, ʻaʻole pono ka hoʻohana ʻana i ka mana; ma mua o ka chromic acid, hāʻawi ākea, nā pono kumu kūʻai haʻahaʻa.
