Ibikoresho byo gukata PCD bifite ubukana buhanitse, imbaraga zo gukomeretsa cyane, ubushyuhe bwiza bwumuriro no kwambara birwanya, kandi birashobora kubona ubuhanga buhanitse kandi bukora neza mugukora vuba.
Ibiranga ibyavuzwe haruguru bigenwa na kristu ya diyama.Muri kristu ya diyama, electroni enye za valence za atome ya karubone zikora umurunga ukurikije imiterere ya tetrahedral, kandi buri atome ya karubone ikora covalent hamwe na atome enye zegeranye, bityo bikagira imiterere ya diyama.Iyi miterere ifite imbaraga zihuza hamwe nicyerekezo, bityo bigatuma diyama ikomera cyane.Kuberako imiterere ya diyama ya polycrystalline (PCD) numubiri wacumuye wa diyama nziza cyane ifite icyerekezo gitandukanye, ubukana bwayo no kwihanganira kwambara biracyari munsi yubwa diyama imwe ya kirisiti nubwo hiyongereyeho binder.Nyamara, PCD yacumuye umubiri ni isotropic, ntabwo rero byoroshye gucamo indege imwe ya clavage.
2. Itandukaniro mubipimo ngenderwaho
Ubukomezi bwa PCD bushobora kugera kuri 8000HV, inshuro 80 ~ 120 za karbide ya sima;Muri make, PCD ifite serivisi ndende kandi itezimbere umusaruro.
Ubushyuhe bwumuriro wa PCD ni 700W / mK, inshuro 1.5 ~ 9 za karbide ya sima, ndetse irenze iyo PCBN n'umuringa, bityo kohereza ibikoresho bya PCD birihuta;
Coefficient de friction ya PCD muri rusange ni 0.1 ~ 0.3 gusa (coefficient de fraisation ya karbide ya sima ni 0.4 ~ 1), ibikoresho bya PCD rero bishobora kugabanya cyane imbaraga zo guca;
Coefficient yo kwagura ubushyuhe bwa PCD ni 0.9 × 10 ^ -6 ～ 1.18 × 10 ^ - 6, ikaba ari 1/5 gusa cya karbide ya sima, bityo rero guhindagura ubushyuhe bwibikoresho bya PCD ni bito kandi ibyakozwe neza ni byinshi;
Ubusabane hagati yigikoresho cya PCD nicyuma kitagira amabara nibikoresho bitari ibyuma ni bito cyane, kandi chip ntabwo byoroshye guhuza kumutwe wigikoresho kugirango ubike chip mugihe cyo gutunganya
