Ke ʻimi nei nā mea noiʻi Kepani i nā palena o ka ʻoki ʻana i ka ʻilika seramika

Ua hoʻohana nā kānaka noiʻi Kepani i nā mea hana daimana polycrystalline e ʻoki i nā seramika Al2O3 a me nā seramika Si3N4. Ua ʻike ʻia ʻo nā mea hana daimana polycrystalline coarse-grained i ʻoi aku ka liʻiliʻi i ka wā o ka ʻoki ʻana a ua maikaʻi ka hopena o ka hana. I ka ʻoki ʻana i nā ceramics ZrO2 me nā mea hana daimana, hiki i ka hopena like me ka wā e ʻoki ai i ka metala. Ua ʻimi lākou i nā palena o ka ʻoki ʻana i ka ʻilika seramika. ʻO ka hohonu o ka ʻokiʻoki koʻikoʻi o nā seramika Al2O3 he apmax=2um, SiC ceramics apmax=1um, Si3N4 ceramics apmax=4um (ap>apmax, nā mea seramika e hoʻohua i nā hemahema;
