Ko te whakakikorua hiko he tikanga e heke ai te konganuku mai i te electrolyte na roto i te mahi a te naianei ka tukuna ki runga i te mata o te ahanoa kia whiwhi i te paparanga hipoki whakarewa.
piauau:
He ngawari te waikura o te konutea ki te waikawa, te kawakore, me te sulfide.Ko te paparanga konutea te nuinga o te wa ka pahemo.I muri i te paheketanga i roto i te otinga chromate, ko te kiriata passivation i hangaia ehara i te mea ngawari ki te taunekeneke me te hau makuku, me te kaha ki te aukati i te waikura ka tino pai ake.I roto i te hau maroke, ko te konutea he ahua pumau me te kore e ngawari ki te huri i te tae.I roto i te wai me te hau makuku, ka tauhohe ki te hāora, te waro hauhā ranei ki te hanga i te waikura, i te kiriata waikawa waro kawakore ranei, ka taea te aukati i te konutea kia kore e haere tonu ki te oxidize me te mahi tiaki.
Nga rauemi e tika ana: te rino, nga waahanga rino
chrome:
He tino pumau te Chromium i roto i te hau makuku, kawakawa, waikawa nitric, sulfide, wairewa warowaiha me te waikawa waro, a he ngawari te wairewa i roto i te waikawa hauwai me te waikawa pungatara wera.Ko te kino ko te mea he uaua, he pakarukaru, he ngawari te taka.Ko te whakakikorua chromium tika i runga i te mata o nga waahanga rino hei paparanga anti-corrosion kaore i te pai.Ko te tikanga, ka taea e te whakakikorua te paparanga-maha (ara te whakakikorua parahi → nickel → chromium) te kaupapa o te aukati waikura me te whakapaipai.I tenei wa, ka whakamahia nuitia ki te whakapai ake i nga kakahu o nga waahanga, te rahi o te whakatikatika, te whakaata marama me te whakapaipai.
Nga rauemi e tika ana: te whakarewa ferrous, te parahi me te koranu parahi kore whakakikorua chrome whakapaipai, whakakikorua chrome-aukati.
Whakakikorua parahi:
Ko te parahi kaore i te pumau i te rangi, a, i te wa ano, he pai te kaha o te kaha, kaore e taea te tiaki i etahi atu konganuku mai i te pirau.Heoi, he nui te kawe hiko o te parahi, he pai, he pai hoki te paparanga whakakikorua parahi, kua honoa ki te whakarewa taketake, he pai te mahi oro. atu electroplating, hei paparanga tiaki ki te aukati carburization, me ki te whakaiti waku whakapaipai ranei i runga i te whanau.
Ko nga rauemi e tika ana: te whakarewa pango, te parahi me te parahi koranu nikel-whakakikoruatia, te paparanga o raro kua whakakikoruatia ki te chrome.
Whakakikorua Nikeli:
He pai te noho matū a Nickel i roto i te hau me te rei, a, ehara i te mea ngawari ki te huri i te tae, engari he ngawari te whakarewa ki te waikawa nitric dilute.He ngawari ki te whakawhiti i roto i te waikawa nitric concentrated, a ko tona kino ko te porosity.Hei whakakore i tenei ngoikoretanga, ka taea te whakamahi i te whakakikorua whakarewa maha-papa, ko te nickel te paparanga waenga.Ko te paparanga nickel whakakikorua he tino pakeke, he ngawari ki te whakakorikori, he nui te whakaata marama me te whakanui ake i te ahua me te aukati, me te pai o te aukati waikura.
Ko nga rauemi e tika ana: ka taea te whakatakoto ki runga i te mata o nga momo taonga, penei i te: rino-nickel-based alloys, zinc-based alloys, aluminum alloys, karaihe, ceramics, plastics, semiconductors me etahi atu rauemi
tine whakakikorua:
He teitei te matū o te tiini.Ehara i te mea ngawari ki te memeha i roto i nga wairewa waimeha o te waikawa pungatara, te waikawa nitric me te waikawa pūhaumāota.Karekau he painga o te sulfide ki te tine.He pūmau hoki te tiini i roto i te waikawa waro, a ko ona pūhui he kore paitini.Ka whakamahia nuitia i roto i nga ipu ahumahi kai me nga waahanga o te rererangi, te whakatere me nga taputapu reo irirangi.Ka taea te whakamahi hei aukati i nga waea parahi kia kore e pangia e te whanariki i roto i te rapa, hei paparanga whakamarumaru mo nga papa kore-nitriding.
Ko nga mea e tika ana: te rino, te parahi, te konumohe me o raatau waahanga
Te koranu tine parahi:
Ko te whakakikorua o te konukura-tinina ko te whakakikorua i te koranu parahi-tine i runga i nga waahanga kaore he whakakikorua nickel, engari ko te whakakikorua tika i te chromium.Ko te Nickel he mea onge me te utu nui.I tenei wa, he nui te whakamahi i te miihini hiko parahi-tinihi i roto i te umanga hiko hei whakakapi i te whakakikorua nickel, he pai te kaha ki te aukati i te waikura.
Ko nga mea e tika ana: nga waahanga rino, nga waahanga parahi me te parahi.
