Ke hana nei ka lapaʻau hoʻopau ʻana i kahi ʻano kaʻina hana papa ma luna o ka ʻili o ka substrate, nona nā ʻano mechanical, kino a me nā mea kemika me nā mea substrate.ʻO ke kumu o ka mālama ʻana i ka ʻili e hoʻokō i ke kūpaʻa corrosion o ka huahana, ka pale ʻana i ka lole, ka hoʻonaninani a i ʻole nā koi hana kūikawā ʻē aʻe.
Ma muli o ka hoʻohana ʻana, hiki ke hoʻokaʻawale ʻia ka ʻenehana lapaʻau i loko o nā ʻāpana aʻe.
ʻO ke ʻano electrochemical
ʻO kēia ʻano hana ka hoʻohana ʻana i ka hopena electrode e hana i kahi uhi i ka ʻili o ka mea hana.ʻO nā ala nui:
(A) Electroplating
I ka hoʻonā electrolyte, ʻo ka mea hana ka cathode, hiki ke hana i kahi kiʻi ʻoniʻoni ma ka ʻili ma lalo o ka hana o waho o kēia manawa, i kapa ʻia ʻo electroplating.
(B) Anodization
I loko o ka hoʻonā electrolyte, ʻo ka mea hana ka anode, hiki ke hana i kahi papa anodized ma ka ʻili ma lalo o ka hana o waho o kēia manawa, i kapa ʻia he anodizing, e like me ka alumini alloy anodizing.
Hiki ke hoʻokō ʻia ka anodization o ke kila e nā ʻano kemika a i ʻole electrochemical.Hoʻokomo ʻia ke ʻano kemika i ka mea hana i loko o ka wai anodized, e hana ia i kahi kiʻiʻoniʻoni anodized, e like me ke kila bluing treatment.
Ke ʻano hana kemika
Ke hoʻohana nei kēia ʻano hana i ka pilina kemika me ka ʻole o kēia manawa e hana i ka uhi kiʻiʻoniʻoni ma ka ʻili mea hana.ʻO nā ala nui:
(A) hoʻololi kiʻiʻoniʻoni lāʻau lapaʻau
I ka hoʻonā electrolyte, ka mea hana i ka ʻole o waho o kēia manawa, ma o ka hoʻonā ʻana o nā mea kemika a me ka launa pū ʻana o ka workpiece e hana i kahi uhi ma luna o kāna kaʻina hana, ʻike ʻia ʻo ka mālama ʻana i ke kiʻi hoʻololi kemika.
Ma muli o ka pilina ma waena o nā mea kemika o ka hopena a me ka mea hana me ka ʻole o waho e hiki ke hana i ke kiʻi ʻoniʻoni ma ka ʻili o ka mea hana, i kapa ʻia ke kiʻi hoʻololi kemika.E like me ka bluing, phosphating, passivating, chromium salt treatment a pēlā aku.
(B) Electroless plating
I ka hopena electrolyte ma muli o ka emi ʻana o nā mea kemika, ua waiho ʻia kekahi mau mea ma luna o ka ʻili o ka mea hana e hana i kahi kaʻina hana, i kapa ʻia ʻo electroless plating, e like me ka electroless nickel plating, electroless copper plating.
ʻano hana wela
Ke hana nei kēia ʻano hana i ka mea hoʻoheheʻe a i ʻole ka hoʻoheheʻe wela i nā kūlana wela kiʻekiʻe e hana i ka uhi kiʻiʻoniʻoni ma ka ʻili o ka mea hana.ʻO nā ala nui:
(A) Hoʻopili wela
E hoʻokomo i nā ʻāpana metala i loko o ka metala i hoʻoheheʻe ʻia e hana i ke kiʻi ʻoniʻoni ma ka ʻili o ka mea hana, i kapa ʻia ʻo ka wela wela, e like me ka hot-dip galvanizing, ka alumini wela a pēlā aku.
(B) Hoʻopuʻi wela
ʻO ke kaʻina hana o ka atomizing a me ka hoʻoheheʻe ʻana i ka metala i hoʻoheheʻe ʻia ma luna o ka ʻili o ka mea hana e hana ai i kahi kiʻi ʻoniʻoni i kapa ʻia ʻo thermal spraying, e like me ka hoʻoheheʻe ʻana i ka zinc, ka wai wela o ka alumini a pēlā aku.
(C) Hehi wela
ʻO ka pahu metala i hoʻomehana ʻia, kaomi ʻia e uhi i ka ʻili o ka mea hana e hana i kahi kaʻina hana kiʻiʻoniʻoni, i kapa ʻia ʻo hot stamping, e like me ka foil foil wela a pēlā aku.
(D) Lapaʻau wela kemika
Hoʻopili i ka mea hana me ke kemika a hoʻokuʻu i kekahi mau mea i loko o ka ʻili o ka mea hana i kahi kūlana wela kiʻekiʻe, i kapa ʻia ka mālama wela kemika, e like me ka nitriding, carburizing a pēlā aku.
Nā ʻano hana ʻē aʻe
ʻO ke ʻano mechanical, kemika, electrochemical, physical method.ʻO nā ala nui:
(A) Ka uhi pena (B) Ka hoʻopaʻa ʻana (C) ka hoʻopau ʻana i ka ʻili laser (D) ʻenehana kiʻiʻoniʻoni paʻakikī loa (E) Electrophoresis a me ka hoʻoheheʻe electrostatic.
