Sintered Silicon Carbide Ceramic Bushing

Silicon carbide sintered tsis muaj siab (SSIC)yog tsim los ntawm kev siv cov hmoov SiC zoo heev uas muaj cov khoom ntxiv sintering. Nws yog ua tiav los ntawm kev siv cov txheej txheem tsim uas ib txwm muaj rau lwm cov khoom siv ceramics thiab sintered ntawm 2,000 txog 2,200 ° C hauv huab cua inert gas. Ib yam li cov qauv zoo-grained, nrog cov noob loj < 5 um, cov qauv coarse-grained nrog cov noob loj txog li 1.5 hli muaj.

SSIC muaj lub zog siab uas nyob ruaj khov mus txog rau qhov kub siab heev (kwv yees li 1,600 ° C), thiab tseem muaj lub zog ntawd mus ntev!

Cov khoom zoo:

Kev ua haujlwm kub siab oxidation

Kev tiv thaiv corrosion zoo heev

Kev tiv thaiv zoo

Cov coefficient siab ntawm kev ua kom sov
Kev siv lubrication, qhov ceev tsawg
Kev nyuaj siab
Kev tsim kho tshwj xeeb.
