Omaka bomkhiqizo

I-siliconized graphite iyinhlanganisela yezinto lapho i-silicon carbide ixhunywe khona ebusweni be-graphite substrate. Inezici zokuqina okuphezulu, amandla aphezulu emishini kanye nokumelana nokugqoka kwe-silicon carbide, kanye nezakhiwo zokuzithambisa kanye nokumelana nokushaqeka okushisayo kwegraphite. Kuyimpahla ekahle yokungqubuzana nezinto ezisetshenziswayo zokuvala uphawu, ezifanele ukuvalwa kwemishini kwamaphampu amanzi ahlukahlukene, amaphampu kawoyela, amaphampu amakhemikhali, nama-bearings amaphampu amakhulu anesivinini esikhulu futhi anomthwalo omkhulu. Ngaphezu kwalokho, i-siliconized graphite inokumelana okuhle kwe-oxidation, ukumelana nokushaqeka okushisayo, i-porosity ephansi, kanye nokuhamba okuthile kagesi, futhi ingasetshenziswa njengezinto ezifana nezinsimbi zokuncibilikisa insimbi namashubhu okusalungiswa.

Ukwakheka kwe-siliconizedi-graphite iyunifomu, indawo engaphezulu ihambisana nengaphakathi, futhi isilinganiso sokwakheka kwe-silicon carbide ne-graphite siyalungiseka. Ukuphakama kokuqukethwe kwe-silicon carbide, kukhulu ukuminyana kwezinto, kuyanda amandla okucindezela, futhi ukumelana nokuqina kuyanda.

(ingxenye emnyama i-graphite, ingxenye empunga i-silicon carbide, kanti ingxenye emhlophe yi-silicon)
