Waea mārō kua whakakikoruatia ki te hauHe whānuitia te whakamahinga mō te whakatika me te hanga i ngā wāhanga ātete-kakahu i roto i te maina, te kuru, te hurihuri maitai me te sima, pērā i ngā hama kuru, ngā raina, ngā awaawa, ngā rōra hurihuri wera me ngā rōra tautoko oumu hurihuri. Ko tana mahi ka whakatau tika i te roa o te mahi o ngā wahi mahi, nō reira ka arotahi ngā kiritaki ki ngā tohu hangarau matua e whai ake nei.
Tuatahi, ko te pakeketanga i muri i te whakapiripiri, e tohuhia ana e te HRC, te tohu tino nui. Ko ngā tohu pakeketanga noa e kapi ana i te HRC 55–58 me te HRC 60–65. He rerekē ngā tohu kua whakawhanakehia mō ngā āhuatanga mahi rerekē: te ātete ki te haukū i te pāmahana rūma, te ātete ki te pāmahana teitei mō ngā rōra hurihuri wera, te ātete ki te pānga teitei me te ātete ki te kakahu pakaru parakore. Me mōhio ko ngā tauira waea kua whakaritea motuhaketia. Kāore e taea te whakamahi tauwhitiwhiti i te tohu mō ngā hama kuru pakaru nui, te tohu mō te kakahu pakaru parakore i runga i ngā awaawa me ngā raina, me te tohu pāmahana teitei mō ngā rōra hurihuri wera.
Tuarua, he tino āta tirotirohia te hanganga whakarewa me te hanganga matū. Ko ngā ihirangi o te Cr, C, Nb, Mo me te V ka whakatikatikaina kia rite ki ngā whakaritenga hoahoa. Ko ngā momo e wātea ana ko te hiato tungsten carbide, te rino maka chromium teitei, ngā tohu maitai kore waikura martensitic me te austenitic. Mō ngā kiritaki keri me te whakarewa o tāwāhi, ka taea te whakarato i te tiwhikete whakamātautau rauemi (MTC) ina tonoa hei manatoko i te hanganga matū.
Ko te aro nui ki ngā pakaru tētahi atu āwangawanga nui, inā koa mō ngā mahi nunui pērā i ngā roera hurihuri taumaha me ngā mea whakarewa matotoru. Ka tirohia e ngā kaihoko mēnā ka pakaru te paparanga mata, mēnā ka taea te whakarewa paparanga maha, ā, mēnā me whakamahana mua me te tiaki i te wera i muri i te whakarewa i te wā o te tukanga whakarewa. Mā te ātete pakaru koretake ka tere te tihore me te pakaru o te paparanga mārō.
Ka aro nui hoki ngā kaihoko ki te roa o te whakamahinga. E whakataurite ana rātou i te roa o te whakamahinga ki ngā hua mai i ētahi atu kaiwhakarato. He mea nui ngā raraunga tono mara me ngā tauira mahi tūturu mō ngā mīhini kuru, ngā rōra hurihuri me ngā rōra tautoko oumu hurihuri hei aromatawai.
Hei tāpiritanga, kāore e taea te wareware i te whakamahinga o te whakarewa. Ko ngā mea matua ko te taumata o te para, te kaha ki te tango i te paru me te hanganga o ngā pītiti whakarewa. Ko te nuinga o ngā mira maitai me ngā wheketere keri e whakamahi ana i ngā taputapu mata aunoa, pērā i ngā mīhini mata pewa tuwhera me ngā mīhini mata pewa ruku. Ko te hototahi pai ki ngā pūnaha whakarewa aunoa ka whakarite kia pumau te whāngai, kia rite te kounga whakarewa me te pai o te whakaputa.
