Usoro ọgwụgwọ okpomọkụ

Ọtụtụ n'ime ha na-eji aluminum alloy ibu cell, nke a na-rụrụ mgbe oghere na-esichara n'ime na-agbanwe ọcha, tumadi gụnyere agbara quenching usoro, oyi na-ekpo ọkụ okirikiri usoro na mgbe niile okpomọkụ ịka nká usoro.

(1) Ụzọ nkwụsị azụ

A na-akpọkwa ya usoro jụrụ oyi na ngwa ngwa ọkụ na China. Tinye aluminum alloy elastic element na mmiri mmiri nitrogen na -196 ℃, debe okpomọkụ maka awa 12, wee fesaa ya ngwa ngwa na uzuoku dị elu ọhụrụ ma ọ bụ tinye ya na mmiri esi. N'ihi na nrụgide nke mmiri jụrụ oyi na ikpo ọkụ ngwa ngwa na-emepụta na-adị n'akụkụ dị iche iche, ha na-akagbu ibe ha wee nweta nzube nke ịhapụ nrụgide fọdụrụnụ. Nnwale ahụ na-egosi na enwere ike ibelata nrụgide fọdụrụnụ site na 84% site na iji usoro uzuoku mmiri nitrogen-oke ọsọ yana site na 50% site na iji usoro mmiri esi mmiri nitrogen.
