Ngā Tohu Hua

Mahi Matua: Hei parau i waenga i ngā rarangi me te whakangāwari i te oneone o ngā hua.

Ka wetekina te oneone kua kikī, me te kore e pakaru ngā pakiaka o te hua, e hurihia rānei te paparanga oneone.

ka whakapai ake i te rere o te hau me te uruhanga wai o te oneone, ka whakanui ake i te rokiroki wai me te makuku

te kaha pupuri i te pakiaka, ā, ka whakatairanga i te tipu o te hua.

He mea hanga te hua mai i ngā rauemi koranu kounga teitei e rua, arā, te maitai manganese 65Mn me te maitai boron 30MnB, i hangaia mā te hanga i te pāmahana teitei. He matotoru te hanganga o te rauemi, ā, kāore he hapa whakarewa pērā i ngā pūwero me ngā kōhao onepu. Mā te whakamahi i te tukanga maimoatanga wera tinei isothermal, ka eke te pakeke o te pito koko ki te 48-52HRC, ā, ka noho tonu te pakari o te matrix ki runga ake i te 35-40J/cm², ka tutuki ai te āhua mahi tino pai o te "pakeke o waho me te pakari o roto". Kua pāngia te mata tapahi e te maimoatanga whakapakari ā-rohe auau-teitei, me te pakeke neke atu i te 55HRC me te whakapai ake i te ātete kakahu.

He āhua piko te mata o te koko parau, ā, ka tika te tatau i te koki whakaurunga (ka taea te whakarerekē mai i te 22° ki te 28°), ka whakaiti i te ātete kukume mā te 15% -20%. Ka honoa te pito o te koko me te pakitara koko i roto i te whakawhiti hikoi hei whakakore i ngā pūwāhi kukū ahotea. He rite tonu ki ngā kōhao whakatika ārai wetewete pūrua, ka whakamahia tahi me ngā nati raka-ake hei whakarite kia roa te mahi me te kore e wetewete. Ko ētahi tauira he atanga pito koko ka taea te whakakapi, ā, ko ngā wāhanga o mua anake me whakakapi i muri i te tawhito o te pito koko, ka whakaiti i ngā utu tiaki.

Tautoko Mahi: Ka taea te whakamahi me ngā mīhini ahuwhenua pēnei i ngā mīhini mahi ahuwhenua,

ngā mīhini rui, ngā mīhini oneone raro, me ngā mīhini huri hei whakaoti i ngā mahi pēnei i te tango otaota, te keri i te awaawa, te tango i ngā kakau witi,

me te whakahoro i te oneone ki raro. Ka taea hoki te whakamahi mō te whakarite whenua i mua i te rui me te whakahaere tipu,

te tapahi i ngā pakiaka taru me te tango i ngā taru o te mara, ka waihanga i te taiao oneone pai mō te tupu o ngā hua.
