Ko te rereketanga i waenga i nga maimoatanga phosphating me te passivation i roto i nga konganuku kei roto i o raatau kaupapa me o raatau tikanga.

Ko te Phosphating tetahi tikanga nui mo te aukati i te waikura i roto i nga taonga whakarewa.Ko ona whainga ko te whakarato i te whakamarumaru i te waikura ki te whakarewa turanga, ka mahi hei kaimatai i mua i te peita, te whakarei ake i te piri me te aukati waikura o nga paparanga paninga, me te mahi hei whakahinuhinu i te tukatuka whakarewa.Ka taea te whakarōpūtia te Phosphating ki nga momo e toru i runga i ona tono: 1) whakakikorua phosphating, 2) phosphating extrusion matao whakahinuhinu, me 3) phosphating whakapaipai.Ka taea hoki te whakarōpūtia e te momo phosphate e whakamahia ana, penei i te zinc phosphate, te zinc-calcium phosphate, te rino phosphate, te zinc-manganese phosphate, me te manganese phosphate.I tua atu, ka taea te whakarōpūtia te phosphating ma te pāmahana: te pāmahana teitei (i runga ake i te 80 ℃) te phosphating, te pāmahana-waea (50-70 ℃) te phosphating, te pāmahana iti (tata ki te 40 ℃) te phosphating, me te pāmahana-rūma (10-30 ℃) phosphating.

I tetahi atu taha, me pehea te paahitanga i roto i nga konganuku, a he aha tana tikanga?He mea nui kia mahara ko te paahitanga he ahuatanga na te pahekoheko i waenga i te wahanga whakarewa me te wahanga otinga, na nga ahuatanga atanga ranei.Kua whakaatuhia e te rangahau te paanga o te abrasion miihini ki runga i nga konganuku i roto i te ahua kore.Ko nga whakamatautau e tohu ana ko te abrasion tonu o te mata whakarewa ka puta he huringa kino nui i roto i te pumanawa whakarewa, ka whakahohe i te whakarewa i roto i te ahua kore.E whakaatu ana tenei he ahuatanga atanga ka puta ina pa ana nga konganuku ki tetahi reo i raro i etahi tikanga.Ka puta te paheketanga hiko i te wa o te polarization anodic, ka puta he huringa i te kaha o te whakarewa me te hanga o te waikura whakarewa, te tote ranei ki runga i te mata hiko, ka hanga he kiriata hāngū me te whakangao whakarewa.Ko te paheketanga matū, i tetahi atu taha, ko te mahi tika a te hunga whakapouri pera i te HNO3 kukū ki runga i te whakarewa, te hanga kiriata waikura ki runga i te mata, te taapiri ranei o nga konganuku ngawari penei i te Cr me te Ni.I roto i te paheketanga matū, kia kaua e taka te kukū o te kaitakawaenga whakauru ki raro i te uara nui;ki te kore, kare pea e whakakorikori haere, ka tere ake te whakarewatanga o te whakarewa.
