Nxiba iiseramikhi ezimelana nokumelanazii-ceramics ezikhethekileyo ze-corundum ezisebenzisa i-AL2O3 njengezinto eziphambili zokwenza imveliso, ii-oxides zesinyithi ezinqabileyo njenge-flux, kwaye ziyosiwe kubushushu obuphezulu be-1,700 degrees. Emva koko zidityaniswe nerabha ekhethekileyo kunye nezihlanganisi ze-organic/inorganic ezinamandla aphezulu. Imveliso.
Ngoku iiseramikhi ezimelana nokuguguleka ze-alumina zisasazeke kulo lonke imarike kwaye zisetyenziswa kakhulu kwisinyithi, amalahle, amandla obushushu, isamente, ukunyibilikisa kunye neminye imimandla. Ngoko ke ungazikhetha njani iiseramikhi ezimelana nokuguguleka?
1. Ukuqina kweeseramikhi ezingagugiyo
Ngokubanzi xa zisetyenziswa kwizixhobo ezahlukeneyo, abantu badla ngokukhetha amaphepha e-ceramic angagugiyo, ancamathiselwe ngqo kumphezulu wezixhobo ukukhusela izixhobo ekugugeni. Ngenxa yobukhulu obuncinci bamaphepha e-ceramic, anokusetyenziswa ngokulula kwizixhobo zeemilo ezahlukeneyo. Izixhobo ezahlukeneyo zisebenzisa i-ceramics ezinobunzima obahlukeneyo, obumiselwa ngokusekelwe kwiimeko zokusebenza.
2. Ukumelana nokunxitywa
Iimeko zokusebenza ezikhethekileyo zifuna ukusetyenziswa kweeseramikhi ezinganyangekiyo, ezifana neeseramikhi ze-alumina eziqinileyo ze-ZTA. Iiseramikhi ze-alumina eziqinileyo ze-ZTA zongeza izithako ezithile zeseramikhi ze-zirconia ngokusekelwe kwi-alumina. Ukumelana nokuguguleka kunye nokuqina kuphakathi kweeseramikhi ze-alumina kunye neeseramikhi ze-zirconia. Iiseramikhi ze-ZTA zinokumelana nokuguguleka okungcono kuneeramikhi ze-alumina ezingama-95%. zilungile.
3. Ubushushu bokusebenza
Okwesibini, kufuneka kuqwalaselwe ubushushu bokusebenza kwezixhobo, nto leyo egqiba indlela yokufakela iiceramics ezinganyangekiyo ukuqinisekisa ukuba iiceramics ezinganyangekiyo azinakuwa phantsi kweemeko zobushushu obuphezulu. Ukuba izinto ezinkulu ziyathuthwa, ubunzulu bempembelelo kufuneka buvavanywe ngokusekelwe kwizinto ezifana neempawu zezinto, ubungakanani bamasuntswana, ukuhla, i-engile yokukhukuliseka, njl.njl. ukuqinisekisa ukukhethwa kweeceramics ezifanelekileyo ezinganyangekiyo.
