Feem ntau peb feem ntau yuav tsum tau kho cua sov thaum ua cov khoom pistis piston. Tom qab ntawd koj paub vim li cas yuav tsum tau kho cua sov. Tus txheej txheem ua tus txheej txheem puas ua tiav?
Qhov tseeb, txoj kev kho kom sov yog ib qho tseem ceeb hauv kev siv cov khoom pistis piston. Tom qab kho tshav kub, qhov chaw ntim hnyav thiab kev ua kom hnyav tuaj yeem kho tau zoo dua, thiab qhov tawg tau tom qab quenching yog txo kom tsawg;
Qhov thib ob, dhau ntawm kev kho cua kub, qhov teeb meem toughness ntawm pist pas nrig yuav ua tau zoo tuaj, kom nws tuaj yeem siv rau qhov chaw ua haujlwm qis dua. Nyob rau hauv qhov tseeb, nws yog los txhim kho qhov zoo ntawm piston pas nrig raw khoom los ntawm ntau yam, thiab zoo cuag lub neej kev pab cuam ntawm piston pas nrig;
Tsis tas li ntawd, cov khoom siv kub-piston piston pas nrig muaj ntau dua vim tias cov txheej txheem minimizes brittleness ntawm nws cov ntaub ntawv raw. Nws tuaj yeem pom tias cov txheej txheem kev kub yog qhov tseem ceeb ntawm kev siv lub piston pas nrig khoom, yog li tsimnyog txhawm rau txhawm rau txheeb xyuas cov txheej txheem kev kho cua sov.
