Abashakashatsi b'Abayapani bashakisha imipaka yo gukata plastike ceramic

Abashakashatsi b'Abayapani bakoresheje ibikoresho bya diyama ya polycrystalline mu guca ubukorikori bwa Al2O3 na ceramika ya Si3N4. Byagaragaye ko ibikoresho bya diyama ya polycrystalline yuzuye ibinyamisogwe bitagira imyenda mike mugihe cyo gutema kandi ingaruka zo gutunganya zari nziza. Iyo ukata ububumbyi bwa ZrO2 hamwe nibikoresho bya diyama, byageze Ingaruka isa nigihe cyo gutema ibyuma. Bakoze ubushakashatsi ku mbibi zo gukata plastiki ceramic. Ubujyakuzimu bukomeye bwa ceramika ya Al2O3 ni apmax = 2um, SiC ceramics apmax = 1um, Si3N4 ceramics apmax = 4um (ap> apmax, ibikoresho bya ceramic bizana kunanirwa gukabije; mugihe ap
