Anodizing—Kekahi ano o ka lapaau ana i ka ili

Anodizing mea he metala ili lapaʻau process.it hiki ke hoʻohana 'ia maʻāpana mīkini CNC,

E pili ana ia i kahi ʻenehana pale i mea e hana ai i kahi kiʻiʻoniʻoni oxide ma luna o ka ʻili o kahi mea metala i loko o kahi hopena electrolyte ma o ka hoʻopili ʻana i kahi au anodic, ʻike ʻia hoʻi ʻo surface anodic oxidation.

Ma hope o ka anodized o ka mea metala a huahana paha ma luna o ka ʻili, ʻoi aku ka maikaʻi o kona kūpaʻa ʻana i ka corrosion, paʻakikī, pale ʻana i ka lole, insulation a me ka pale wela.ʻO ka mea metala anodized loa he alumini.Lawe ʻia ka anodization o ka alumini i kahi electrolyte acidic, me ka alumini ka anode.I ke kaʻina hana electrolysis, pili ka anion o ka oxygen me ka alumini e hana i kahi kiʻiʻoniʻoni oxide.ʻAʻole lawa ka paʻakikī o kēia ʻano kiʻiʻoniʻoni i ka wā i hana mua ʻia ai.ʻOiai he kūpaʻa kona, hiki i nā ion oxygen maikaʻi ʻole i ka electrolyte ke hiki i ka ʻili o ka alumini a hoʻomau i ka hana ʻana i kahi kiʻiʻoniʻoni oxide.Ke piʻi aʻe ka mānoanoa o ke kiʻiʻoniʻoni, piʻi pū ke kū'ē, a no laila ke emi nei ka manawa electrolysis.I kēia manawa, hoʻoheheʻe ʻia ke kiʻiʻoniʻoni o waho e pili ana me ka electrolyte.Ke hoʻohālikelike ʻia ka nui o ka hoʻokumu ʻana o ka oxide ma ka ʻili alumini me ka wikiwiki o ka hoʻoheheʻe kemika, hiki i ke kiʻi ʻoniʻoni ke hiki i ka mānoanoa kiʻekiʻe ma lalo o kēia koho electrolysis.He porous ka papa waho o ke kiʻi anodized o ka alumini, a he maʻalahi ke komo i nā mea pena a me nā mea kala, no laila hiki ke hoʻoluʻu a hoʻomaikaʻi i kāna mau mea hoʻonaninani.Ma hope o ka hoʻopaʻa ʻia ʻana o ke kiʻi ʻoniʻoni me ka wai wela, ka mahu wela a i ʻole ka paʻakai nickel, hiki ke hoʻomaikaʻi hou ʻia kona kūpaʻa ʻana a me ke kūpaʻa ʻana.

Ma waho aʻe o ka alumini, nā metala i hoʻohana ʻia i ka ʻoihana noanodization ilii loko o ka magnesium alloys, keleawe a me ke keleawe, zinc a me zinc alloys, titanium alloys, kila, cadmium, tantalum, zirconium, etc.

E ʻoluʻolu e nānā i kekahi kiʻi e pili ana i ka anodizing e like me lalo:

Inā makemake ʻoe i kēia ʻano huahana, e ʻoluʻolu e kelepona mai iā mākou me ka manuahi!
