Dab tsi yog qhov txheej txheem kev kho kub kub kho

Cov tsoos tuag - casting pwm kub txheej txheem kev kho mob yog quenching - tempering, thiab ces cov kev kho tshuab ntws tau tsim. Vim tias muaj ntau yam khoom siv uas siv los ua cov hmoov pwm tuag, casting pwm, thiab cov txheej txheem cov txheej txheem sib txawv yuav txawv txav ntawm cov khoom sib txawv.Kefu shi tso rau pem hauv ntej pom ntawm cov khoom pwm puag thiab cov khoom siv ntom ntom tshuaj ntawm substrate pretreatment kev siv technology, los ntawm kev sib txuas ntawm cov khoom siv sib txawv, rau cov txheej txheem sib txawv pwm rau kev ua haujlwm, ua kom txhim kho pwm, txhim kho lub neej kom tuag. kev pab cuam lub neej ntawm kev tuag casting mould.Tuaj raws li cov tshuaj tua hluav taws xob tshuaj carbonitriding, nrog cov pa quenching thiab tempering txheej txheem ntawm NQN (namely cov carbonitriding, quenching thiab carbonitriding qhov cuab lub zog, tsis tsuas tau txais siab deg hardness, thiab qhov tob ntawm hardening txheej ntxiv, muaj kuab faib ntawm carboni traum txheej hardness gradient, tempering stability thiab corrosion kuj, thiaj li ua rau tuag casting pwm hauv zoo lub plawv koom kev kawm tib lub sij hawm, txhim kho qhov nto zoo thiab kev ua tau zoo
