Martensitic graded quenching: ígwè na-austenitized, na mgbe ahụ na-emikpu n'ime mmiri mmiri ọkara (nnu bath ma ọ bụ alkali bath) na a okpomọkụ ubé elu ma ọ bụ dịtụ ala karịa elu Martensite n'ókè nke ígwè, na nọgidere na-enwe maka oge kwesịrị ekwesị ruo n'ime na Mpụta elu nke ígwè akụkụ Mgbe n'ígwé ruru ọkara okpomọkụ, a na-ewepụtara maka ikuku jụrụ, na supercooled austenite ji nwayọọ nwayọọ ghọọ martensite n'oge quenching usoro. A na-ejikarị ya eme ihe maka obere workpieces nwere ọdịdị dị mgbagwoju anya na ihe ndozi siri ike chọrọ. A na-ejikwa usoro a emenyụ ngwa ngwa nchara dị elu na ngwa igwe na-akpụ akpụ.
4. Martensite graded quenching usoro n'okpuru isi okwu
Martensite graded quenching usoro n'okpuru Ms point: Mgbe bat okpomọkụ bụ ala karịa Ms nke workpiece ígwè na elu karịa Mf, na workpiece cools ngwa ngwa na bath, na otu esi dị ka graded quenching ka nwere ike nweta mgbe size bụ ibu. Ọtụtụ mgbe, eji maka ibu ígwè workpieces na ala hardenability.
5. Bainite isothermal quenching usoro
Bainite isothermal quenching method: A na-emenyụ ihe arụrụ arụ n'ime bat nke nwere okpomọkụ bainite dị ala nke nchara na isothermal, nke mere na mgbanwe bainite dị ala na-eme, a na-edebekwa ya na bath maka nkeji 30 ruo 60. Usoro bainite austempering nwere usoro atọ bụ isi: ① austenitizing ọgwụgwọ; ② ọgwụgwọ jụrụ oyi nke post-austenitizing; ③ bainite isothermal ọgwụgwọ; a na-ejikarị na alloy steel, nnukwu carbon ígwè obere akụkụ na nkedo ductile.
6. Usoro nkwụsị nke ngwakọta
Ngwakọta quenching usoro: mbụ menyụọ workpiece ka n'okpuru Ms nweta martensite na a olu nta nke 10% ka 30%, na mgbe ahụ isotherm na ala bainite mpaghara nweta martensite na bainite owuwu maka ibu cross-ngalaba workpieces. Ọ na-ejikarị Alloy ngwá ọrụ ígwè workpieces.
7. Precooling na isothermal quenching usoro
Usoro ikpo ọkụ isothermal na-eme ka ọ dị jụụ: nke a na-akpọkwa ikpo ọkụ isothermal quenching, akụkụ ndị ahụ na-ebu ụzọ mee ka ọ dị jụụ na bat nke nwere okpomọkụ dị ala (dị ukwuu karịa Ms), wee bufee ya na bat nke nwere okpomọkụ dị elu iji mee ka austenite nwee mgbanwe nke isothermal. Ọ dabara maka akụkụ ígwè na-adịghị mma hardenability ma ọ bụ nnukwu workpieces nke a ga-austempered.
8. Usoro nju oyi na-egbu oge
Usoro nkwụsị jụrụ oyi na-egbu oge: A na-ebu ụzọ mee ka akụkụ ahụ dị jụụ n'ikuku, mmiri ọkụ, ma ọ bụ nnu na-asa ahụ na okpomọkụ dịtụ elu karịa Ar3 ma ọ bụ Ar1, mgbe ahụ, a na-eme nkwụsị nke ọkara. A na-ejikarị ya eme ihe maka akụkụ ndị nwere ọdịdị dị mgbagwoju anya na nha dịgasị iche iche na akụkụ dị iche iche na-achọ obere nrụrụ.
9. Usoro imenyụ na iwe ọkụ
Usoro nkwụsị na iwe onwe ya: A na-ekpo ọkụ dum workpiece a ga-edozi, ma n'oge nkwụsịtụ, ọ bụ naanị akụkụ nke kwesịrị ime ka ike sie ike (na-emekarị akụkụ ọrụ) na-emikpu n'ime mmiri na-ekpo ọkụ ma mee ka ọ dị jụụ. Mgbe agba ọkụ nke akụkụ a na-emikpughị na-apụ n'anya, wepụ ya ozugbo na ikuku. Usoro nkwụsịtụ jụrụ oyi. Usoro nkwụsị na nke onwe ya na-eji okpomọkụ sitere na isi nke na-adịghị mma zuru oke iji nyefee n'elu iji kpasuo elu. Ngwa ndị a na-ejikarị egbochi mmetụta dị ka chisel, ọkpọ, hama, wdg.
10. Usoro ịgbanyụ ọkụ
Usoro ịgbanyụ ọkụ: Usoro nkwụsị nke a na-efesa mmiri n'ime ihe eji arụ ọrụ. Mmiri mmiri nwere ike ịbụ nnukwu ma ọ bụ obere, dabere na omimi nkwụsị nke achọrọ. The ịgba quenching usoro adịghị etolite a uzuoku film n'elu nke workpiece, si otú huu a miri ike oyi akwa karịa mmiri quenching. A na-ejikarị emenyụ elu mpaghara.
