I roto i te tikanga ki te whakapai ake i te pakeke mata, me te kakahu ātete opaipa tapawhā, ka taea te tukatuka etahi o te mata, ara te mata o te mura parakore o te ahi, teitei, te whakapakeke o te mata auau takawaenga me etahi maimoatanga matū me nga mea pera.Ko te tikanga teitei, te whakapakeke o te mata auau takawaenga o te nuinga, ka wera i te mahana o te 850-950℃.I te mea he ngoikore te kawe i te waiariki, no reira kare te tere whakawera i te tere rawa, ki te kore ka rewa me etahi koha ka tinei kapiti.Ko nga whakaritenga whakapakeke arataki Ko te Pupa Tapawhā te whakarite matrix te nuinga o te pearlite.Ko te wai rehu whakamahana, he otinga wai ranei o te waipiro polyvinyl, te whakamahana i te pāmahana i roto i te awhe o te 200-400℃, te pakeke 40-50HRC, te pakeke me te whakakakahu i te parenga ki te whakarite i te mata Pipe Tapawhā.

Ko te maimoatanga wera paipa tapawhā e toru nga painga e whai ake nei:

(A) Te mau tonu o te ahu mo te putorino tapawha tika, me tino tika, me mau tonu te ahua o te ahua, na te mea ka tika te kura ki te hau, he puhoi te reiti whakamahana, no reira kua tau te mahi a austenite ka nui ake te nui o te pupuri. austenite kiko putorino tapawhā, me maimoatanga makariri;

(B) Whakaititia distortion tinei e tika ana ki te tapawha elongated me te tapawhā ngongo, na te tukanga whakapakeke ngāwari deformed, me tino whakahaeretia deformation, maimoatanga wera he taahiraa nui i roto i te tukanga tinei, te whakamahi o te kirihou kia supercooled austenite tīaroaro wā, i te mea he mahi matua ki te whakarite i to raatau reeti rite, mo te mea me whakamaarama te horoi wera me te whakamatao whakamahana whakamahana i te whakamahana i te wa ka whakairihia te whakamahana ki runga i te whakamahana, hei whakaiti i te whakapakeketanga o te hinu, mo te tereina arahi-nui, hei whakaiti i te huringa. o te hau nitriding ranei plasma nitriding, etc;

(C) He nui te pakeke o te tapawha matua me te ngongo tapawha ka mau ki nga taumahatanga o te ngenge, me kaha te pakeke, na reira me whakapakeke, te whakamaroke ranei, te maimoatanga wera matū ranei, ka whai i te mahi whakamahana.
