Cov kabmob kev ua tau zoo cov yam ntxwv cov yam ntxwv tseem ceeb yog li hauv qab no:
1, txhuam kev sib txhuam: cov khoom sib txuam muaj qhov sib txhuam tsis tshua muaj siab.
2, hnav tsis kam: qhov hnav tsis kam ntawm cov khoom, feem ntau qhia nyob rau hauv cov nqe lus ntawm hnav tus nqi.
3, tom tsis kam (cov nplaum): cov tiv tshav kub thiab tiv thaiv kev nplaum ntawm cov khoom.
4. Kev txhuam kev sib txhuam: qhov muaj peev xwm ntawm cov khoom siv los them rau qhov tsis zoo thaum pib ntawm qhov zawv zawg ntawm cov kabmob los ntawm elastoplastic deformation ntawm qhov saum npoo.
5, kos ua ke: cov khoom siv haum cov khoom sib zog ua ke, yog li txo qhov kev ua haujlwm ntawm khawb los yog abrasive coj ntawm cov nplaim ntu ntawm cov kabmob.
6, khiav-hauv: cov kabmob hav zoov thiab cov ntawv xov xwm saum npoo tom qab lub sijhawm luv luv ntawm lub teeb ua haujlwm, kev tsim ntawm cov nplaim ntawm ib leeg
Lub peev xwm (lossis zoo) ntawm cov duab thiab ntxhib.
7, ntxiv rau, yuav tsum muaj lub zog txaus thiab tiv thaiv corrosion, zoo thermal conductivity, technology thiab kev lag luam.
Tiaj tus kabmob cov kabmob hav zoov hom khoom:
Cov ntaub ntawv siv cov khoom siv dag nqa dav dav yog: cov khoom siv hlau, cov khoom siv tsis yog xim hlau thiab hmoov hlau cov ntaub ntawv
Cov ntaub ntawv cov hlau feem ntau siv cov kabmob hlau (Babbitt alloy, dawb alloy) yog tsim ntawm tin, txhuas, antimony, tooj liab thiab lwm cov alloys;Tooj liab tooj liab, uas yog muab faib ua tooj dag thiab tooj dag ob pawg;Cam khwb cia hlau muaj hom grey cam khwb cia hlau, zas cam khwb cia hlau, thiab lwm yam.
Dais cov ntaub ntawv tsis yog xim hlau muaj yas, tawv tawv, roj hmab, ntawm lawv cov yas nrog cov feem ntau
Bearing hmoov metallurgy cov khoom siv yog ua los ntawm tooj liab, hlau, graphite thiab lwm cov hmoov los ntawm nias thiab sintering rau hauv cov khoom ntxeem tau cov kabmob.
