2. Mpweya wochepa wa carbon ukhoza kuonetsetsa kuti mankhwalawa ali ndi kuuma kwapamwamba komanso kuvala kukana panthawi ya kutentha, ndipo mpweya wochepa wa carbon pakatikati umapangitsa kuti mankhwalawa akhale ndi zotsatira zabwino.

3. Kuwonjezera 2% -3% Ni ndi 2% Cu kuzinthu kungathe kusintha kwambiri mwadala ndi mphamvu yamphamvu yazinthu pambuyo poyimitsa.

4. Poyerekeza ndi carburizing ndi quenching, carbonitriding ali bwino kuvala kukana, ndipo m'munsi carbonitriding kutentha amaonetsetsa mphamvu ya pachimake pa gawo ndi kuchepetsa quenching mapindikidwe mbali.

Ufa zitsulo magiya, monga mbali zitsulo ufa ambiri ntchito injini galimoto, angathe kukwaniritsa zofunikira za kulondola zida ndi bwino kusintha processing dzuwa mwa nthawi imodzi kupanga ndi kutsiriza ndondomeko popanda pambuyo processing.
