Abashakashatsi b'Abayapani bakoresheje ibikoresho bya diyama bya polycrystalline mu gukata ibumba rya Al2O3 na Si3N4. Byagaragaye ko ibikoresho bya diyama bya polycrystalline bifite imiterere iciriritse byangiritse cyane mu gihe cyo gukata kandi ingaruka zo gutunganya zari nziza. Mu gukata ibumba rya ZrO2 hakoreshejwe ibikoresho bya diyama, byageze ku ngaruka. Ingaruka ni nk'iyo mu gukata icyuma. Basuzumye aho pulasitiki ya ceramic igarukira. Uburebure bw'ingenzi bwo gukata ibumba rya Al2O3 ni apmax=2um, SiC ceramics apmax=1um, Si3N4 ceramics apmax=4um (ap>apmax, ibikoresho bya ceramic bizatuma habaho kwangirika; iyo ap
