Dab tsi yog qhov high quenching?

Quenching yog ib hom kev kho cua sov, suav nrog kev quenching, pulse quenching thiab isothermal quenching.

Feem ntau, quenching ua rau lub workpiece muaj qee qhov microstructure los xyuas kom meej tias ib ntu ua tau raws li qhov yuav tsum tau muaj cov khoom siv tom qab tempering. tuaj yeem txhim kho hardness thiab lub zog; nce hnav tsis kam.

Pulse quenching yog kom sov lub workpiece nyob rau hauv ib tug luv luv lub sij hawm (xws li 1/1000 thib ob) nrog kev pab los ntawm lub siab zog ntawm lub mem tes, thiab txias nws sai heev, uas yuav tau txais tsis tshua muaj zoo nplej thiab siab hardness, tsis muaj deformation, tsis muaj oxide zaj duab xis, Hnav-resistant thiab corrosion-resistant. Tsis tas yuav tsum tau tempering tom qab quenching.

Austempering yog kom sov lub workpiece mus rau lub quenching kub, thiab ces muab tso rau hauv ib tug sov so ntsev da dej uas ua rau ib tug tej yam qauv hloov rau lub sij hawm ntawm lub sij hawm kom tau txais bainite thiab lwm yam lug, kom nws muaj zog dua thiab toughness. Lub quenching kev ntxhov siab yog me me, uas tuaj yeem tiv thaiv denaturation thiab tawg. Haum rau nyias thiab loj qhov chaw.
