Ke ʻōlelo nei mākou ʻo ka oxidation o ka alumini alumini he anodic oxidation.ʻOiai ʻo ka anodic oxidation a me ka electroplating e koi i ka uila, aia nā ʻokoʻa koʻikoʻi ma waena o nā mea ʻelua.
E nānā mua i ka anodizing, ʻaʻole kūpono nā metala āpau no ka anodizing.ʻO ka maʻamau, ua hoʻohana ʻia nā mea hao metala, a hoʻohana nui ʻia ka alumini.ʻO ka oxidation anodic ka hoʻohana ʻana i ka metala oxidized (aluminum) e like me ka anode a hana i ka hoʻoheheʻe electrolytic ma o ka haʻahaʻa haʻahaʻa haʻahaʻa pololei e hana i kahi kiʻi ʻoniʻoni oxide ma ka ʻili o ka mea, ʻo ia ka oxide o kāna metala ponoʻī.
ʻOkoʻa ka electroplating.He kūpono ka electroplating no ka mālama ʻana i ka ʻili o nā metala like ʻole a me nā metala ʻole.Hiki ke hoʻopaʻa ʻia nā ʻano metala āpau a me kekahi mau metala ʻole ke hoʻopaʻa ʻia i ka mālama ʻana i ka ʻili.ʻOiai he lau lahilahi, hiki ke hoʻopaʻa ʻia i ka electroplated i ka wā e mālama pono ʻia ai.ʻOkoʻa mai ka anodic oxidation, hoʻohana ʻia ka mea e hoʻopaʻa ʻia ma ke ʻano he cathode, hoʻoikaika ʻia ka metala plating ma ke ʻano he anode, a aia ka metala plating i ka electrolyte i ke kūlana o nā ion metala.Ma o ka hopena hoʻopiʻi, neʻe nā iona metala o ka anode i ka cathode a waiho i ka mea cathode e uhi ʻia.ʻO nā metala uhi maʻamau he gula, kālā, keleawe, nickel, zinc, etc.
Hiki ke ʻike ʻia ʻo ka alumini alloy oxidation a me ka electroplating ʻelua ka mālama ʻana i ka ʻili, hiki ke hoʻokō i nā hopena maikaʻi a anti-corrosion.ʻO ka ʻokoʻa ma waena o nā mea ʻelua ʻo ia ka electroplating e hoʻohui i kahi papa pale metala ʻē aʻe ma luna o ka ʻili o ka mea kumu ma o nā hopena kino, ʻoiai ʻo ka anodization e hoʻoneʻe electrochemically i ka ʻili o ka metala.
ʻO ke ʻano hana lapaʻau maʻamau i hoʻohana ʻia no nā mea alumini alumini he anodization, no ka mea, ʻoi aku ka maikaʻi o ka ʻili anodized, ʻoi aku ka ikaika o ka corrosion, a me ka mālama maʻalahi.A hiki ke oxidized a kala ʻia ka mea alumini alumini e loaʻa ai nā kala i makemake ʻia.
