Nke mbụ, mgbe ibelata olu mmanụ n'ime ọkụ ọkụ na-ekpo ọkụ mmanụ na tank mmanụ na nkata ọkọlọtọ, ebe dị n'etiti mmanụ na elu ya kwesịrị ịbụ opekata mpe 100 mm.
Ọ bụrụ na anya dị ihe na-erughị 100 mm, okpomọkụ nke elu mmanụ ga-adị elu, nke nwere ike iduga mgbawa nke ọkụ ọkụ.
Nke abuo, a ghaghi ewebata nitrogen tupu ewepụta mmanụ n'ọkụ na-emenyụ mmanụ, mana enweghị ike iwebata ikuku. Iji chekwaa ego, ọtụtụ ndị na-emepụta ihe anaghị eji nitrogen eme ihe.
Tụkwasị na nke ahụ, ọ kacha mma ịgbanye nitrogen tupu ahapụ ọrụ ahụ, ma ọ bụghị ya, ọ dị mfe ime ka mgbawa nke ngwa ọkụ ọkụ ọkụ.
Nke atọ, workpiece okpomọkụ gafere ókè mgbe igbapu mmanụ. N'oge a, mmanụ na-ekpochapụ agụụ ga-ekupụ, ozugbo ọ banyere n'ikuku ma ọ bụ oxygen, ọ ga-agbawa.
Nke anọ, na mgbakwunye na akụrụngwa ọgwụgwọ okpomọkụ n'onwe ya, ịdị mma nke ikuku na-ekpochapụ mmanụ n'onwe ya ga-ebutekwa ihe mberede mgbawa, dị ka imenyụ mmanụ nwere obere ọkụ na ebe mgbanyụ ọkụ dị ala.
Nke ise, size na udi nke workpiece quenched na agụụ mmanụ quenching ọkụ bụkwa otu n'ime ihe kpatara mgbawa ahụ.
Ya mere, onye ọ bụla kwesịrị ịṅa ntị iji gbochie ihe mberede kpatara ihe ndị a. Nke mbụ, ọ dị mkpa ka a na-enyocha akụrụngwa ma na-echekwa ya mgbe niile.
Iji chọpụta ma gbakwunye mmanụ n'ime ọkụ na-ekpo ọkụ n'oge, ọ ka mma ịnweta onye na-ebubata mmanụ na-ekpochapụ agụụ,
N'ihi na mmanụ sitere n'ọtụtụ ndị na-emepụta ihe na-enwekarị ihe mberede. Nke abuo, mgbe quenching size bụ nnukwu, oké na oge ụfọdụ, ọ dị mfe ịmepụta ọnụ ọgụgụ buru ibu nke quenching mmanụ ngwaahịa.
