ʻO ke kumu nui o ka mālama ʻana i nā ʻāpana metallurgy pauka:
1. E hoʻomaikaʻi i ka pale ʻana i ka ʻaʻahu
2. Hoʻonui i ka pale ʻana i ka corrosion
3. Hoʻonui i ka ikaika luhi

Hiki ke hoʻokaʻawale ʻia nā ʻano hana lapaʻau i hoʻohana ʻia i nā ʻāpana metallurgy pauka i nā ʻāpana ʻelima:
1. Ka uhi ʻana: E uhi i ka ʻili o ka ʻāpana i hana ʻia me kahi papa o nā mea ʻē aʻe me ka ʻole o ka hopena kemika
2. Lapaʻau kemika o ka ʻili: ka hopena kemika ma waena o ka ʻili o ka ʻāpana i hana ʻia a me ka reactant waho
3. Hoʻomaʻamaʻa wela kemika: ʻo nā mea ʻē aʻe e like me C a me N hoʻolaha i ka ʻili o ka ʻāpana i hana ʻia
4. ʻO ka hoʻomaʻamaʻa ʻana i ka wela o ka ʻili: hoʻololi ʻia ka hoʻololi ʻana o ka pae e ka hoʻololi cyclic o ka mahana, e hoʻololi i ka microstructure o ka ʻili o ka ʻāpana i hana ʻia.
5. Mechanical deformation ala: e hana i ka mechanical deformation ma luna o ka ili o ka mea i hanaʻia, ka mea nui e hana compressive koena koʻikoʻi, me ka hoonui ana i ka ili ili.

Ⅰ.Ka uhi ʻana
Hiki ke hoʻopili ʻia ka electroplating i nā ʻāpana metallurgy pauka, akā hiki ke hana wale ʻia ma hope o ka hoʻomaʻamaʻa ʻana o nā ʻāpana metallurgy pauka (e like me ke kuʻi ʻana i ke keleawe a i ʻole ke kuʻi ʻana i ka wax e hoʻopaʻa i nā lua) e pale ai i ke komo ʻana o ka electrolyte.Ma hope o ka mālama ʻana i ka electroplating, hiki ke hoʻomaikaʻi pinepine ʻia ka pale ʻana o nā ʻāpana.ʻO nā laʻana maʻamau ka galvanizing (hoʻohana hou i ka chromate no ka passivation ma hope o ka galvanizing e loaʻa i kahi ʻeleʻele a i ʻole ka pūʻali ʻōmaʻomaʻo ʻōlinolino) a me ka nickel plating
ʻOi aku ka maikaʻi o ka nickel plating electrolytic ma mua o ka electrolytic nickel plating i kekahi mau ʻano, e like me ka kāohi ʻana i ka mānoanoa o ka uhi a me ka pono plating.
ʻAʻole pono e hoʻokō ʻia ke ʻano "maloʻo" zinc coating a ʻaʻole pono e hoʻopaʻa ʻia.Ua mahele ia i ka pauka galvanizing a me ka mechanical galvanizing.
Ke koi ʻia ka anti-rust, anti-corrosion, hiʻohiʻona nani a me ka insulation uila, hiki ke hoʻohana ʻia ke pena.Hiki ke hoʻokaʻawale ʻia nā ʻano hana: ka uhi ʻana i ka plastic, glazing, a me ka hoʻoheheʻe metala.

Ⅱ.Surface kemika lapaʻau

ʻO ka hoʻomaʻamaʻa mahu ka mea maʻamau o nā kaʻina hana lapaʻau āpau no nā ʻāpana metallurgy pauda.ʻO ka hoʻomaʻamaʻa ʻana i ka mahu e hoʻomāhana i nā ʻāpana i 530-550°C i loko o kahi ea mahu e hana ai i kahi papa honua magnetic (Fe3O4).Ma o ka oxidation o ka ili o ka hao matrix, ua hoʻomaikaʻi ʻia ka ʻaʻahu a me nā waiwai friction, a ua kūpaʻa nā ʻāpana i ka hana Rust (hoʻoikaika hou ʻia e ka ʻaila immersion) ʻO ka papa oxide ma kahi o 0.001-0.005mm mānoanoa, e uhi ana i ka ʻili āpau o waho. , a hiki ke hoʻolaha i ke kikowaena o ka ʻāpana ma o nā pores pili.ʻO ka hoʻopiha ʻana i kēia pore e hoʻonui i ka ʻike paʻakikī, a laila e hoʻomaikaʻi i ke kūpaʻa ʻaʻahu a loaʻa iā ia kahi degere haʻahaʻa o ka compaction.

ʻO ka mālama ʻana i ka phosphate anuanu he hopena kemika i loko o ka ʻauʻau paʻakai e hana i ka phosphate paʻakikī ma ka ʻili o ka mea hana.Hoʻohana ʻia ʻo Zinc phosphate no ka hoʻomaʻamaʻa mua ʻana i nā uhi a me nā ʻili plastik, a hoʻohana ʻia ka manganese phosphate no nā noi friction.

Hana ʻia ka bluing ma ka waiho ʻana i ka mea hana i loko o ka ʻauʻau potassium chlorate ma 150°C e ka ʻino kemika.He uliuli uliuli ka ili o ka mea hana.ʻO ka mānoanoa o ka papa bluing ma kahi o 0.001mm.Ma hope o ka bluing, nani ka ʻili o nā ʻāpana a he hana anti-rust.

Hoʻohana ka kala Nitriding i ka nitrogen mākū ma ke ʻano he oxidant.I ka wā o ka hoʻoluʻu ʻana o ka mea hana ma hope o ka sintering, ua hoʻokumu ʻia kahi papa oxide i ka pae wela o 200-550 ° C.Hoʻololi ke kala o ka papa oxide i hana ʻia me ka mahana hana.

Hoʻohana ʻia ka lāʻau anti-corrosion anodized no nā ʻāpana alumini e hoʻomaikaʻi i kona helehelena a me ka hana anti-corrosion.

Hoʻohana ʻia ka lapaʻau Passivation i nā ʻāpana kila kila, ka mea nui e hana i kahi papa pale pale oxide.Hiki ke hana ʻia kēia mau oxides ma ka hoʻomehana ʻana a i ʻole ma nā ʻano kemika, ʻo ia hoʻi, ka hoʻoulu ʻana me ka waikawa nitric a i ʻole ka hopena sodium chlorate.I mea e pale aku ai i ka hoʻonā ʻana mai ka hoʻoinu ʻana, kemika Pono ke ʻano o ka hoʻomaʻamaʻa wax pre-sealing.
