Zida zokutira zili ndi mphamvu yabwino komanso kulimba kwa carbide kapena chitsulo chothamanga kwambiri (
Ceramics, diamondi ndi cubic boron nitride zida zolimba kwambiri monga lumo zimathanso)
Pamwamba, ntchito njira nthunzi mafunsidwe ❖ kuyanika wosanjikiza kuvala zosagwira zitsulo refractory kapena nonmetal pawiri ndi kukonzekera.
Kupaka ngati chotchinga mankhwala a chida kudula ndi chotchinga matenthedwe, akhoza kuchepetsa mayamwidwe ndi zochita mankhwala pakati wodula ndi workpiece, potero kuchepetsa masanjidwewo a kuvala ndi kung'ambika, kuti patsogolo moyo utumiki wa kudula zida.
Zida TACHIMATA ali mkulu pamwamba kuuma ndi kuvala kukana, khola mankhwala katundu, wabwino kutentha kukana makutidwe ndi okosijeni, otsika mikangano coefficient ndi otsika matenthedwe madutsidwe, akhoza kuchepetsa adhesion chodabwitsa, n'kosavuta kupanga chotupa devolop etc, pamene kudula zida TACHIMATA ndi apamwamba. kuposa moyo wosavala chida chodulira komanso kuthamanga kwachangu kumakhala kosalala, zambiri zimatha kuchepetsa kutayika kwa chida chodulira.
Zida zokutira zidzagawidwa m'mitundu inayi: zida zachitsulo zothamanga kwambiri, zida zokutira za carbide, komanso zoumba ndi zida zolimba kwambiri (
Diamondi kapena kiyubiki boron nitride)
Tsamba pa zida zokutira.
Koma mitundu iwiri ya zida zokutira imagwiritsa ntchito kwambiri.
Mu zitsulo zadothi ndi zokutira zakuthupi zolimba kwambiri pa tsamba ndi kuuma kunali kotsika kusiyana ndi zipangizo za matrix, cholinga chake ndi kupititsa patsogolo kulimba kwa fracture pamwamba pa tsamba (
Mutha kuwonjezera kuposa 10%)
, imatha kuchepetsa m'mphepete mwa tsamba ndikuwonongeka, kukulitsa kuchuluka kwa ntchito.
