Waea Kovar 4j29, Waea 29HK mō te Hanga me te Wheketere o te Koranu Hiri Karāhe, he mea hanga mai i Haina

Waea Kovar 4j29, he koranu whānui iti, he waea 29HK mō te koranu hiri karāhe

Whakaahuatanga Poto:

Koranu-4J29 (Koranu whakawhanui)
(Ingoa noa: Kovar, Nilo K, KV-1, Dilver Po, Vacon 12)
Ko te Alloy-4J29 e mōhiotia ana ko te Kovar alloy. I hangaia hei whakatutuki i te hiahia mō tētahi hiri karāhe-ki-te-konganuku pono, e hiahiatia ana i roto i ngā taputapu hiko pēnei i ngā pūangi rama, ngā ngongo korehau, ngā ngongo hihi katote, me ngā pūnaha korehau i roto i te matū me ētahi atu rangahau pūtaiao. Kāore e taea e te nuinga o ngā konganuku te hiri ki te karāhe nā te mea kāore tō rātou tauwehenga whānui wera i rite ki te karāhe, nō reira i te mea ka mātao te hononga i muri i te hanganga, ko ngā taumahatanga nā ngā tere whānui rerekē o te karāhe me te konganuku ka pakaru te hononga.

Ehara i te mea he rite te whānui o te wera o te Alloy-4J29 ki te karāhe, engari he maha ngā wā ka taea te hanga i tōna pihi whānui kore-raina kia rite ki te karāhe, kia taea ai e te hononga te aro atu ki te whānuitanga o te pāmahana. I roto i te matū, ka honoa ki te karāhe mā te paparanga waikura waenga o te waikura nikara me te waikura cobalt; he iti te ōwehenga o te waikura rino nā tōna whakahekenga ki te cobalt. Ko te kaha o te hononga e tino whakawhirinaki ana ki te matotoru me te āhua o te paparanga waikura. Mā te noho mai o te cobalt ka māmā ake te rewa me te memeha o te paparanga waikura i roto i te karāhe rewa. Ko te tae hina, hina-kikorangi, hina-parauri rānei e tohu ana i te hiri pai. Ko te tae konganuku e tohu ana i te korenga o te waikura, ko te tae mangu e tohu ana i te konganuku kua tino waikurahia, i ngā āhuatanga e rua ka arahi ki te hononga ngoikore.

Taupānga:E whakamahia ana i roto i ngā wāhanga korehau hiko me te whakahaere tukunga, ngongo ru, ngongo mura, magnetron karāhe, transistors, mono hiri, tānga, ara iahiko whakauru, chassis, whāiti me ētahi atu hiri whare.
