1. Rau high-zog hmoov metallgy iav cov khoom lag luam, nws yuav tsum muaj qhov siab ntom thiab tau txais cov txheej txheem ntawm "nias - kev kho mob ua ntej - Refiring Kev Kho Mob".

2. Cov ntsiab lus qis dua tuaj yeem ua kom ntseeg tau tias cov khoom muaj qhov tawv tawv thiab hnav tsis kam thaum kho cua sov, thiab cov pa roj carbon tsawg hauv cov tub ntxhais yuav ua rau cov khoom muaj kev cuam tshuam zoo.

3. Ntxiv 2% -3% Ni thiab 2% Cu rau cov khoom tuaj yeem txhim kho lub siab nyiam thiab cuam tshuam lub zog ntawm cov khoom tom qab sintering.

4. Piv nrog rau carburizing thiab quenching, carbonitriding muaj zoo hnav tsis kam, thiab qis carbonitriding kub ua kom lub zog ntawm cov tub ntxhais ntawm ib feem thiab txo cov quenching deformation ntawm ib feem.

Hmoov metallurgy iav, raws li cov hmoov hlau metallurgy feem ntau siv nyob rau hauv lub tsheb cav, muaj peev xwm ua tau raws li qhov yuav tsum tau ntawm iav qhov tseeb thiab ua kom zoo dua qub los ntawm kev tsim ib zaug thiab ua tiav cov txheej txheem tsis muaj lwm yam tom qab ua tiav.
