Whakaahuatanga Poto:

Ko te pito parau, he wāhanga āwhina mō ngā mīhini ahuwhenua, he mea hanga mai i te maitai kaha, ātete ki te pakaru, ā, ka whakarei ake tōna pakeke me tōna pakari mā te whakamahana. Mā tōna hoahoa mata tapahi koi ka whakaitihia te ātete ina uru ki te oneone, ka ngāwari te tapahi i roto i te oneone kua whakakīia. Ka matotoru, ka whakapakarihia hoki ngā wāhi matua kia ātete ki te pānga me te ātete ki te pakaru, ka roa ake ai tōna roanga mahi. He pai mō ngā tauira parau hurihuri me ngā parau papa pokepoke, ā, mā tōna ngāwari ki te wetewete me te whakakapi ka whakaitihia ngā utu ahuwhenua me te wā kore mahi.

Ngā Tohu Hua

He wāhanga matua tēnei o te mīhini parau whenua—te pito o te parau parau—e tika ana mō ngā parau papa pokepoke, ngā parau hurihuri, me ngā parau oneone o raro. Hei wāhanga e pā tuatahi ana ki te oneone, ā, e mau ana i te waku me te pānga nui rawa atu, ko tōna kounga te mea e whakatau tika ana i te ātete parau whenua, te whai huatanga o te wahie, me te pumau o te hohonu mahi. Ka whakamahia e tēnei pito o te parau parau he hanganga whakakotahi o te "matihao kaha-teitei + te koranu mārō whakarara," ka tutuki ai he taurite i waenga i te urunga koi ki te oneone, te ātete kakahu me te whakaiti i te tōia, me te pakari o te pānga. Ka roa ake te huringa whakakapinga, ka whakaitihia hoki te utu whakahaere toharite mō ia eka.

Matrix: He mea hanga ki te maitai hanganga koranu kaha-teitei 30MnB, 40Cr rānei, he mea hanga ki te wera, he matotoru te matotoru, kāore he porosity o roto. I muri i te hanga, ka tukuna he maimoatanga tinei me te whakamahana kia whiwhi ai i te hanganga martensitic whakamahana. Ko te pakari pānga matrix he ≥50J/cm², ka taea te mimiti i ngā pānga rangitahi mai i ngā kōhatu me ngā pakiaka rākau, ka kore ai e pakaru, e pakaru rānei.

Paparanga ātete-kākahu: Ka whakamahia te whakarewa plasma, te whakakikorua laser rānei ki te mata oneone o te pito parau (te wāhi kākahu o te mata tapahi o mua me te mata o runga) hei whakakikorua i te rino maka konupora-teitei, te koranu rino whakakaha-tungsten carbide rānei. Ka taea e te whakakikorua whakarewa te eke ki te pakeke o te HRC 58-62, me te matotoru o te 2.5-4.0 mm, ka hanga he hononga whakarewa ki te papa, ka whakakore i te tūponotanga o te kiri. I raro i ngā āhuatanga kākahu tere-teitei i roto i te oneone, ka hangaia e ngā matūriki pakeke he āhua "tautoko-iti" tiaki-ake, ka whakaiti i te tere kākahu ki te 1/3 noa iho o ngā pereti maitai 65Mn noa.

Hoahoa Āhuahanga: Ka arotauhia te mata piko o te pito parau i runga i te ara nekehanga māmā o te puranga oneone, ka whakaiti i te koki waku ki te oneone. He hoahoa whaiti haere, he angiangi ngā mata o te wāhanga o mua, ka whakaiti i te pēhanga pakaru oneone; ka mātotoru haere ngā wāhanga o waenganui me muri kia pakari ai te katoa. Kua whakaritea te koki tomo ki te mara mō ngā momo oneone rerekē (onepu, uku, oneone), me te whakakotahi i te kaha tomo pai me te ātete iti ki te kukume.

Ātete Tino Kaha: E whakaatu ana ngā whakamātautau pakaru o te wira rapa onepu maroke taiwhanga he ≤0.25g/kg·m te nui o te pakaru o te waeine. I raro i ngā āhuatanga oneone onepu reo, ka taea e te pito parau kotahi te whakaoti i te 500-800 eka o te mahi, me te roa o te ora e 2.5-3 ngā wā i ngā pito parau maitai 65Mn noa.

Ngā Āhuatanga Whakakoi-Anō: Ka hanga he kakahu tahi te papa whakarewa kua whakapakeketia me te papa ngohengohe—ka tere ake te kakahu o te papa, ka puta ake ngā matūriki karāhe sima i te mata mahi, ka mau tonu te āhua koi o te mata tapahi, ā, ka ārai i te pikinga o te whakapaunga wahie nā te mea ka pōuri.

Ātete pānga me te haumaru: Ina tūtaki ki ngā kohatu huna, ki ngā arai pakeke rānei, e kore te anga whānui e pakarukaru, ā, ko te āhua o te hanganga anake ka puta; he nui te tawhā kirihou hei ārai i te taka o ngā paru ki te mara, me te kino hoki i ngā taputapu e whai ake nei.
