He tikanga hou te whakawera i roto i te oumu korehau, kāore he rere i raro i ngā āhuatanga korehau. Nā te mea kei roto te whakawera i roto i te taiao korehau, ka taea te whakakore i te pānga kino o te hau ki te mea mahi, kia taea ai te whakahaere angitu i te whakawera me te kore e whakamahia he rere. Ko te nuinga o te wā e whakamahia ana mō te whakawera i ngā konganuku me ngā koranu he uaua ki te whakawera, pērā i te koranu konumohe, te koranu titanium, te koranu superalloy, te koranu ātete me te uku. He kanapa, he matotoru te hononga whakawera, he pai ngā āhuatanga miihini me te ātete ki te waikura. Ko ngā taputapu whakawera korehau kāore i te whakamahia mō te whakarewa ngira o te maitai waro me te maitai koranu iti.
Ko ngā taputapu whakakā i roto i te oumu korehau he mea hanga i te oumu whakakā korehau me te pūnaha korehau. E rua ngā momo oumu whakakā korehau: te ahi wera me te ahi matao. Ka taea te whakamahana i ngā momo oumu e rua mā te hau māori, mā te whakamahana hiko rānei. Ka taea te hanga hei oumu taha, oumu raro, oumu runga rānei (momo Kang), ā, ka taea te whakamahi i te pūnaha korehau mō te ao katoa.
Ko te pūnaha korehau te nuinga o te wā ko te wae korehau, te paipa korehau, te takirere korehau, me ētahi atu. Ko te wae korehau he mea hanga mai i te papu miihini hurihuri me te papu tohatoha hinu. Ko te papu miihini whakamahi kotahi ka taea te whiwhi i raro iho i te 1.35 × te nekehanga korehau o te taumata 10-1pa. Hei whiwhi i te korehau teitei, me whakamahi i te papu tohatoha hinu i te wā kotahi, ka taea te eke ki te 1.35 i tēnei wā × te nekehanga korehau o te taumata 10-4Pa. Ka inehia te pēhanga hau i roto i te pūnaha ki te ine korehau.
Ko te whakakoi i roto i te oumu korehau he whakakoi i roto i te oumu, i te rūma whakakoi rānei me te hau e tangohia ana. He tino pai mō te whakakoi i ngā hononga nui me te haere tonu. He pai hoki mō te hono i ētahi konganuku motuhake, tae atu ki te titanium, te zirconium, te niobium, te molybdenum me te tantalum. Heoi, he ngoikoretanga anō hoki ēnei o te whakakoi korehau:
① I raro i ngā āhuatanga korehau, he ngāwari te whakarewa ki te whakapūpū, nō reira kaua e whakamahia te whakapūpū korehau mō te whakarewa turanga me te whakarewa i ngā huānga pūpūpū. Mena e tika ana, me whakamahi i ngā tikanga tukanga uaua e rite ana.
② He mea aro te whakakoi korehau ki te taratara o te mata, te kounga o te huihuinga me te manawanui ki te taunga o ngā wāhanga kua whakakoitia, ā, he nui ngā whakaritenga mō te taiao mahi me te taumata ariā o ngā kaiwhakahaere.
③ He uaua ngā taputapu korehau, he nui te haumitanga kotahi, ā, he nui te utu tiaki.
Nā, me pēhea te whakatinana i te tukanga whakawera i roto i te oumu korehau? Ina whakahaerehia te whakawera i roto i te oumu korehau, whakauruhia te whakarewa me te whakawera ki roto i te oumu (ki roto rānei i te ipu whakawera), katia te tatau o te oumu (katia rānei te taupoki o te ipu whakawera), ka whakawera i mua i te whakamahana. Tīmatahia te papu miihini i te tuatahi, hurihia te takirere urungi i muri i te ekenga o te nekehanga korehau ki te 1.35pa, katia te ara tika i waenga i te papu miihini me te oumu whakawera, honoa te paipa ki te oumu whakawera mā te papu tohatoha, mahi i roto i te wā poto mā te whakawhirinaki ki te papu miihini me te papu tohatoha, papuhia te oumu whakawera ki te nekehanga korehau e hiahiatia ana, kātahi ka tīmata te whakamahana hiko.
I roto i te tukanga katoa o te pikinga pāmahana me te whakamahana, me mahi tonu te wae korehau ki te pupuri i te taumata korehau i roto i te oumu, ki te whakakore i te turuturu o te hau i ngā atanga rerekē o te pūnaha korehau me te oumu whakawera, ki te tukunga o te hau me te mamaoa wai e piri ana ki te pakitara oumu, te hononga me te whakarewa, me te whakakorikori o te konganuku me te waikura, kia whakaitihia ai te maturuturunga o te hau tūturu. E rua ngā momo whakakorikori korehau: te whakakorikori korehau teitei me te whakakorikori korehau wāhanga (korehau waenga). He tino pai te whakakorikori korehau teitei mō te whakakorikori i te konganuku turanga he uaua ki te pirau te waikura (pērā i te konukōre turanga nikara). Ka whakamahia te whakakorikori korehau wāhanga mō ngā wā ka whakakorikori te konganuku turanga, te whakarewa rānei i raro i te pāmahana whakakorikori me ngā āhuatanga korehau teitei.
Mēnā me mahi ngā mahi whakatūpato motuhake hei whakarite i te parakore teitei, me whakamahi te tikanga purenga korehau i mua i te whakakanapa hauwai maroke. Waihoki, mā te whakamahi i te tikanga purenga hauwai maroke, te tikanga purenga hau korehau rānei i mua i te papu korehau ka āwhina i te whiwhi hua pai ake i roto i te whakakanapa korehau teitei.
