Vim li cas ho hnav-resistant steels hnav-resistant?
Cov alloying ntsiab ntawm hnav-resistant steels yog ib qho ntawm cov khoom uas ua rau lawv hnav-resistant dua lwm cov hlau. Wear-resistant steels siv ntau yam alloys los ua kom hnav tsis kam. Piv txwv li, carbon yuav pab ua kom lub zog thiab lub zog ntawm cov hlau. Chromium thiab manganese tuaj yeem pab txo qis hnav.
Kev kho cua sov yog lwm yam hauv cov hlau tsis kam hnav. Hnav-resistant steels yuav tsum muaj ib tug microstructure uas muab lawv siab hardness. Qhov no yog ua tiav nyob rau hauv ib feem los ntawm kev sib ntxiv ntawm tsim nyog alloying ntsiab. Txawm li cas los xij, qhov no tsis txaus los xyuas kom meej tias nws txhim kho qhov tsim nyog microstructure.
Cov hlau tseem yuav tsum tau ua cov txheej txheem ntawm cua sov thiab ceev quenching los tsim cov microstructure. Kev saib xyuas yuav tsum tau ua thaum vuam thiab cua sov hnav-tiv taus steels, zoo li yog tias lawv tau rhuab mus rau qhov kub txaus, cov nyhuv annealing kuj tshwm sim, uas tuaj yeem ua rau txo qis hauv lawv cov tawv tawv thiab, yog li ntawd, lawv hnav tsis kam.
