1. Kalulu ana
He porous maoli nā ʻāpana metallurgy pauda.ʻO ka Impregnation, ka mea i ʻike ʻia he penetration, pili i ka hoʻopiha ʻana i ka hapa nui o nā pores me kēia mau mea: plastic, resins, copper, oil, other material.ʻO ka waiho ʻana i ka ʻāpana porous ma lalo o ke kaomi hiki ke hoʻoheheʻe ʻia, akā inā ʻoe e hoʻoinu i ka ʻāpana, e lilo ia i impermeable i ke kaomi.ʻO nā mea i hoʻohanaʻia no nā'āpana impregnated e pili ana i nā kumu e like me ke kumukūʻai a me ka noi.No ka laʻana, pehu ke keleawe i ka wā o ka sintering, no laila e luku ana i ke kūpaʻa dimensional.ʻO ka hoʻokomo ʻana i loko o ka ʻaila hiki ke lubricate ʻakomi i nā ʻāpana.ʻO nā mea a pau e pili ana i kāu mau koi hoʻolālā.
2. Electroplating
ʻO ka Electroplating kahi mea ʻokoʻa i ke kila kila no nā pono aesthetic a i ʻole nā ​​​​hana pono - hana i nā ʻāpana i ka nānā ʻana, hoʻomaikaʻi i ka pale ʻana i ka corrosion, a pēlā aku.
3. Kiʻi pana
ʻO ka pana ʻana i ka pana ʻana he kaʻina hana densification kūloko, hiki ke hoʻomaikaʻi i ka ʻili o nā ʻāpana ma ka wehe ʻana i nā burrs a kau i ke koʻikoʻi compressive surface i nā ʻāpana.He mea maikaʻi paha kēia i kekahi mau hana luhi.Hoʻopuka ʻia nā lua liʻiliʻi e paʻa ana i ka lubricant ma ka ʻili o ka ʻāpana.Hoʻomaka pinepine ʻia nā māwae luhi e nā hemahema o ka ʻili.Hiki i ka peening pana ke pale pono i ka hana ʻana o nā māwae ili a hiki ke lohi i ka ulu ʻana o nā māwae holoʻokoʻa.
4. Lapaau mahu
Ke hoʻohana ʻia i nā ʻāpana hao, e hana ʻia ka hoʻomaʻamaʻa mahu i kahi ʻāpana oxide lahilahi a paʻakikī.ʻAʻole ʻeleʻele ka papa oxide;He mea ia e pili ana i ka hao.Hiki i kēia papa ke hoʻomaikaʻi i ka pale ʻana i ka corrosion, ka paʻakikī a me ka paʻakikī
