Ngā Paninga Ārai-Kakahu – Te Rehu HVOF mō ngā Ahumahi Katoa
Whakaahuatanga Hua
Ko te Wahie Hāora Tere Teitei (HVOF) he tukanga whakapakari ā-teitei, ā-kore e pakaru, ā-waikura hoki i roto i te mara o te hangarau mata ahumahi.
Ka whakamahia e tēnei tukanga ngā wahie pērā i te hinu kakara me te propane me te hāora pēhanga teitei hei reo. Ka whakaranua pai te ranunga, ā, ka tahuna kaha i roto i te rūma mura o te pū rehu, ka puta he mura tere-teitei me ngā tere neke atu i te Mach 5 (te pāmahana 2600-3200℃). Ka whāngaihia ngā paura mahi-teitei pērā i te tungsten carbide me ngā koranu nickel ki roto i te mura, ka rewa tonutia, ka whakaterea ki ngā tere tino-teitei o te 500-800 m/s. Ka pā tēnei kaha nekeneke kaha ki te mata o te mea mahi, ka hanga he paninga mahi tino matotoru me te piripono mā te whakakotahitanga o te hononga whakarewa me te piri ā-ringa.
He mea whakarite motuhake mō ngā wāhanga matua o te mīhini hinu (ngā mono, ngā nohoanga takirere, ngā kēti, ngā matua takirere, ngā kōpae takirere, me ētahi atu), he tino pai te urutau ki ngā āhuatanga mahi tino uaua o te keri, te mahi anō i te puna, me te kawe hinu me te hau, pērā i te pānga pēhanga teitei, te horo o te paru kei roto i te onepu, te waikura waikawa me te kawakore, me te waku pāmahana teitei. Ka whakatauhia ngā raruraru o te tere o te kakahu, te poto o te ora me te pakaru o te hiri o ngā wāhanga mai i te pūtake, ā, ko te otinga maimoatanga mata matua hei whakapai ake i te pono o ngā taputapu mīhini hinu.

Ngā Āhuatanga o te Hua
1. Ātete Pai ki te Mau me te Horoi:
Ko te pakeke o te paninga he HRC75, ā, he ātete ki te horo tere mai i ngā tapahi toka me te onepu silica i roto i te paru keri. Ko tōna ātete ki te kakahu he 8-15 ngā wā i tērā o ngā tukanga tinei me te whakakikorua hiko noa, ā, ka roa ake te ora o ngā wāhanga.
2. Tino mātotoru, ā, ātete ki te waikura:
Ahakoa te iti o te pūngao o te wai i roto i te 1%, kāore he awa turuturu, e ārai pai ana i ngā mea waikura pērā i te hinu me te hau, ngā wai keri, me te wai tote, e ārai ana i te waikura o te papa me te korenga o te waikura.
