Cheebtsam yog tooj liab infiltrated rau ntau yam.Qee qhov kev xav tau yooj yim yog kev txhim kho lub zog tensile, hardness, cuam tshuam cov khoom, thiab ductility.Copper-infiltrated Cheebtsam kuj tseem yuav muaj qhov ceev dua.

Lwm cov laj thawj cov neeg siv khoom tuaj yeem xaiv cov tooj liab infiltration yog rau kev txhim kho kev hnav lossis txhawm rau thaiv huab cua / roj ntws los ntawm lwm qhov ntxeem tau ntawm qhov kub thiab txias uas cov resin tsis tuaj yeem ua tau.Qee zaum tooj liab infiltration yog siv los txhim kho cov yam ntxwv ntawm PM steel;tooj liab tawm ib smoother machined tiav.

Ntawm no yog li cas tooj liab infiltration ua haujlwm:

Lub hauv paus qauv ntawm cov tivthaiv muaj ib tug paub ceev, uas yog siv los txiav txim tus nqi ntawm qhib porosity.Ib qho kev ntsuas ntawm tooj liab raug xaiv txuam nrog qhov porosity yuav tsum tau ntim.Cov tooj liab sau cov porosity thaum lub sij hawm sintering txheej txheem (ntawm qhov kub siab tshaj qhov kub kub ntawm tooj liab) tsuas yog muab cov tooj liab tiv thaiv cov khoom ua ntej sintering.Qhov> 2000 ° F sintering kub tso cai rau molten tooj liab ntws mus rau hauv cov khoom porosity los ntawm capillary nkaus.Sintering yog ua tiav ntawm cov cab kuj (xws li cov phaj ceramic) yog li cov tooj liab nyob twj ywm ntawm cov khoom.Thaum ib feem yog txias, cov tooj liab yog solidified nyob rau hauv cov qauv.
