Puas yog cam khwb cia hlau xwb?

cam khwb cia hlau me me qhov cub

Lub microstructure ntawm cam khwb cia hlau feem ntau muaj flaky los yog spherical graphite hais, uas muab cam khwb cia hlau nws siab lubrication thiab muaj peev xwm nqus tau kev co. Hlau, ntawm qhov tod tes, feem ntau muaj nruj ntim cov nplej hauv nws cov microstructure.
Vim muaj cov ntsiab lus carbon siab thiab muaj cov graphite hais, cam khwb cia hlau feem ntau yog yooj yim rau cam khwb cia thiab tsim dua li hlau, thiab muaj zog compressive zoo dua thiab hnav tsis kam. Txawm li cas los xij, cam khwb cia hlau tsis zoo plasticity thiab toughness thiab nws yooj yim rau brittle cracking. Nyob rau hauv sib piv, steel feem ntau muaj ntau dua plasticity thiab toughness thiab yog haum rau ntau yam txheej txheem thiab kev siv.

Cam khwb cia hlau thiab hlau sib txawv nyob rau hauv muaj pes tsawg leeg, cov qauv thiab cov khoom, yog li lawv muaj kev siv sib txawv thiab kev siv hauv kev lag luam thiab kev tsim khoom.

Me Log Burners

cam khwb cia hlau tsis zoo ib yam li hlau. Txawm hais tias ob qho tib si feem ntau muaj hlau, lawv muaj ntau yam sib txawv thiab cov khoom. cam khwb cia hlau muaj feem pua ​​​​ntawm cov pa roj carbon ntau dua li cov hlau, feem ntau ntawm 2% thiab 4%, uas ua rau nws muaj qhov sib txawv microstructure thiab cov khoom. Tsis tas li ntawd, cam khwb cia hlau feem ntau muaj lwm yam alloying ntsiab xws li silicon, manganese, sulfur, thiab phosphorus, uas ua rau nws cov yam ntxwv tshwj xeeb xws li siab melting point, zoo hnav tsis kam, thiab zoo heev kub tuav.
Qhov tseeb, carbon muaj pes tsawg leeg yog qhov sib txawv tseem ceeb ntawm cov hlau cam khwb cia hlau thiab hlau. Cam khwb cia hlau feem ntau muaj ntau dua 2 feem pua ​​carbon, thaum cam khwb cia hlau feem ntau muaj nyob nruab nrab ntawm 0 1-0.5 feem pua ​​carbon.
