Taupānga me te Whakatakotoranga (Kore) :

Te maimoatanga wera o te putorino maitai korekore kua kumea mai e te makariri:

(1) matao unu maitai annealing: e pā ana ki te mea whakarewa te wera ki te pāmahana e tika ana, ki te mau tonu i tetahi wa, a ka āta whakamatao tukanga maimoatanga wera.Ko te tikanga whakapouri noa ko: te whakahiatotanga, te whakamaarama i te ahotea, te whakapoipoi poipoi, te rena katoa me etahi atu.Ko te kaupapa o te whakahiato: ko te nuinga ki te whakaiti i te pakeke o te rauemi whakarewa, ki te whakapai ake i te kirihou, ki te tapahi ranei i te tukatuka ki te tukatuka pehanga Liqie, te whakaiti i te ahotea o te toenga me te whakapai ake i te riterite o te microstructure me te hanganga, te maimoatanga wera, i muri i te taea, te whakarite kiko ranei.

(2) te whakamahana o te maitai, te maitai ranei ki te Ac3, ki te Acm ranei (te pāmahana tino nui o te maitai) neke atu i te 30 ~ 50℃, i muri i te wa tika ki te whakamatao i roto i te hau tonu i roto i te tukanga maimoatanga wera.Ko te kaupapa o te whakarite: ko te nuinga ki te whakapai ake i nga ahuatanga miihini o te waro waro iti hei whakapai ake i te miihini, te whakamahine witi, te whakakore i nga ngoikoretanga o te kiko, te whakarite mo te maimoatanga wera, i muri i te whakarite kiko.

(3) whakamaroke rino kumea matao: e pa ana ki te rino whakawera Ac3, Ac1 ranei (he iti ake te pāmahana tino nui o te maitai) i runga ake i tetahi pāmahana mo tetahi wa, katahi ka tika te reiti whakamahana ki te whiwhi kiko martensite (te maataitai Heat Treatment ranei) kiko.Ko te tikanga tinei kaukau tote noa kua whakapakeke, tinei martensitic, Austempering, whakamaroke mata me te tinei wahanga.Quenching kaupapa: ki te hanga i te maitai e hiahiatia ana ki te whiwhi martensite whakapai ake pakeke workpiece, kaha me te mau ātete, maimoatanga wera, i muri i te faaineineraa mo te whakahaere me te faaineineraa.

(4) matao unu maitai riri: e i muri i whakapakeke maitai, a ka wera ki te pāmahana i raro Ac1, te pupuri i tetahi wa, a ka mātao ki te pāmahana rūma, te tukanga maimoatanga wera.Ko te tukanga whakamaarama noa ko: te whakamaarama, te whakamaarama, te whakamaarama me te maha o nga mahi.Ko te kaupapa o te whakamahana: ko te nuinga o te rino te whakakore i te ahotea i puta i te wa e tinei ana, he nui te pakeke o te rino me te mau atete, engari ko te kirihou me te uaua e hiahiatia ana.

(5) tinei rino matao unu: e pā ana ki te tinei me te tempering o maitai ranei hiato tukanga maimoatanga wera wera.Whakamahia i roto i te tinei ka mea maitai tineia me te tempered maitai.Ko te tikanga e pa ana ki te hanganga waro o te waro maitai me te maitai koranu.

(6) te maimoatanga matū rino toka matao: e pa ana ki nga mea whakarewa, koranu ranei i whakanohohia ki roto i te mahana tonu o te wera reo kaha, kia kotahi, maha atu ranei nga huānga ki tona mata ki te huri i tana hanganga matū, hanganga moroiti me nga ahuatanga o te tukanga maimoatanga wera. .Ko te tukanga maimoatanga wera matū noa ko: carburizing, nitriding, carbonitriding, aluminized boron penetration.Ko te kaupapa o te maimoatanga matū: Ko te mea nui ko te whakapai ake i te pakeke o te mata rino, te mau atete, te aukati waikura, te kaha ngenge me te aukati waikura.

(7) maimoatanga otinga rino kumea matao: ka whakamahana te koranu ki tetahi rohe-waahanga teitei teitei kia mau tonu te pāmahana, kia rewa katoa te waahanga taikaha ki roto i te otinga totoka i muri i te whakamahana tere, kia pai ake ai te haunga. otinga totoka tukanga maimoatanga wera.Ko te kaupapa o te maimoatanga otinga: te nuinga ki te whakapai ake i te ductility me te uaua o te maitai me te koranu, ki te whakarite mo te maimoatanga whakapakeke o te rerenga me etahi atu.

Ko te paninga Phosphate mo te tuhi i nga ngongo kua hangaia inaianei me te taumaha o te 4-10

g/m².Na tenei i pai ake te pai o te maimoatanga o te mata, a, i te wa ano, ka karo i nga paanga kino ka puta i te waahanga tuhi tuatahi i kitea ai te paninga phosphate-crystalline phosphate.Ko te whakakikoruatanga pai rawa atu i runga i te waikawa/nitrite whakatere konutea hosphate, i hanga i te 40-75°C. I te pito o runga o tenei awhe pāmahana, kei te waatea te kowhiringa ki te whakamahi i nga punaha momo pākawa toha-whaiaro.Ka kitea hoki nga pati konutea phosphate whakatere maaota.I nga wa katoa, ko te ahua pai o te phosphate mo te tuhi matao o te ngongo me te waahanga he tino piri engari he ngawari te hanganga.I roto i te tuhi o te ngongo paiherea, me matua whakamaroke te tui ki raro.Mena he iti ake te diametertubing, kaore e taea tenei i roto i te miihini whakapiri.I etahi wa, tera pea he whakarereketanga hei hoatu i tetahi waahanga whiti.Mai i te mea ko te tikanga, he iti ake te kino o nga deformations ka taea e te paiherea, he rereke ki te

ngongo korekore, kua horahia te whakamahinga o te phosphating, ko te taumaha o te paninga te ota 1.5 – 5 g/m².Ko te nuinga o enei ka ahu mai i nga pati zinc phosphate e whakahaerehia ana i waenga i te 50 ki te 75°C me nga taapiri e whakamahia ana ki te whakatairanga i nga paninga angiangi. Ka whakamahia ano te Phosphating mo te ngongo o te rino kore-kore, te iti-kotahi ranei me te ihirangi chromium ki runga ki te 4-6%. Ko enei momo whakakikoruatanga he maha nga painga, ka puta katoa mai i te whakaheke whakarewa-ki- whakapiri whakarewa i waenganui i nga ngongo me te mate.No reira, ka whakaitihia te kino o te weriweri matao, ka puta he haehae, kapiti ranei, ka roa ake te ora o te taputapu me te mate, ka nui ake te reiti tuhi.Ka taea hoki e te paninga konutea phosphate te whakahekenga ake mo ia haere.

Ka mahia te maimoatanga mata ma te rumaki i nga rarangi e whai ake nei:

•Te whakaheke waikaraka.

•Horoi wai.

•Piki i roto i te sulfuric waikawa pūhaumāota ranei.

•Horoi wai.

•Te whakakore i mua i te horoi.

•Phosphating.

•Horoi wai

•Te horoi horoi.

•Whakahinuhinu.

•Te whakamaroke me te rokiroki.
