Superhard meafaigaluega meafaitino faasino i le superhard mea e mafai ona faaaoga e avea o se meafaigaluega tipi. I le taimi nei, e mafai ona vaevaeina i ni vaega se lua: mea meafaigaluega tipi taimane ma cubic boron nitride mea meafaigaluega tipi. E lima ituaiga autu o mea fou na faʻaaogaina pe o loʻo faʻataʻitaʻiina
(1) Fa'anatura ma fa'atupu fa'akomepiuta taimane tioata lapoa
(2) Poly taimane (PCD) ma poly taimane composite lau (PDC)
(3) CVD taimane
(4) Polycrystal cubic boron ammonia; (PCBN)
(5) CVD kupita boron amonia ufiufi
1, fa'anatura ma fa'apipi'i tele taimane tioata tasi
O le taimane masani o se fausaga tioata tutusa e aunoa ma se tuaoi o fatu i totonu, ina ia mafai ai e le pito o meafaigaluega ona oʻo atu i le atomic smoothness ma le maʻai, ma le malosi o le tipiina, maualuga maualuga ma le malosi o le tipi. O le maaa, le ofuina o le teteʻe ma le corrosion teteʻe ma le mautu vailaʻau o taimane natura mautinoa le umi o le ola o le meafaigaluega, e mafai ona mautinoa le tipiina masani umi, ma faaitiitia le aafiaga o meafaigaluega ofuina i luga o le saʻo o vaega gaosi, o lona conductivity vevela e mafai ona faaitiitia le vevela tipi ma le vevela deformation o vaega. O uiga lelei o le taimane tioata tasi masani masani e mafai ona ausia le tele o manaʻoga o le saʻo ma le ultra-saʻo tipiina mo mea faigaluega. E ui lava o lona tau e taugata, o loʻo amanaʻia pea o le mea saʻo lelei ma mea meafaigaluega ultra precision, e mafai ona faʻaaogaina lautele i le gaosiga o reactors faaniukilia ma isi tekinolosi maualuga i le fanua o faʻata, missiles ma rockets, komipiuta hard disk substrate, accelerator electron gun super precision machining, ma vaega matamata masani, teuga, peni, afifi uʻamea teuteu saʻo taotoga e mafai foi ona faʻaaogaina, ma isi. scalpel, lau tino manifinifi ma isi meafaigaluega faafomai. O le atinaʻeina o loʻo i ai nei o le maualuga o le vevela ma le maualuga o le faʻaogaina o tekonolosi e mafai ai ona saunia se taimane tioata tasi e tasi ma se lapopoa. O le lelei o lenei mea faigaluega taimane o lona tele lelei, foliga ma le faʻatinoinaO le tumau, lea e le maua i oloa taimane masani. Ona o le utiuti o le tele tele sapalai taimane natura, tau taugata, synthetic tele fasimea tioata taimane meafaigaluega meafaitino i ultra-saʻo tipitipi e pei o se taimane tioata taimane natura tele, o le a vave atiina ae lona talosaga.
2, polycrystal taimane (PCD) ma polycrystal taimane tu'ufa'atasi lau (PDC) fa'atusatusa i taimane tioata tasi tele o se mea meafaigaluega o polycrystal taimane (PCD) ma polycrystal taimane tu'ufa'atasi lau (PDC) o lo'o i ai tulaga lelei nei: (1) saito disordered faatulagaga, isotropic, leai luga cleavage. O le mea lea, e le pei o le taimane tioata tasi tele i luga tioata eseese malosi, maaa
Ma o le ofuina o le teteʻe e matua ese lava, ma ona o le i ai o le cleavage luga ma e malepelepe.
(2) e maualuga le malosi, aemaise lava le mea faigaluega PDC ona o le lagolago o le carbide matrix ma e maualuga le aʻafiaga o le tetee, o le a naʻo le aʻafiaga e maua ai saito laiti gau, e le pei o se tasi tioata taimane pa'ū tele, faʻapea ma le PCD poʻo le PDC meafaigaluega e le gata e mafai ona faʻaaogaina mo le tipi saʻo ma le afa masani machining. Ae e mafai foi ona faʻaaogaina e pei o se aofaʻi tele o masini faʻaogaina ma faʻalavelave faʻafuaseʻi (e pei o le milling, ma isi), lea e matua faʻalauteleina ai le faʻaogaina o mea faigaluega taimane.
(3) Ole tele ole PDC meafaigaluega avanoa e mafai ona saunia e faʻafetaui ai manaʻoga o mea faʻaoga tetele e pei ole milling cutter.
(4) E mafai ona faia foliga faʻapitoa e faʻafetaui ai manaʻoga o gaioiga eseese. Ona o le faʻaleleia atili o le PDC meafaigaluega faʻapipiʻi ma le faʻaogaina o tekonolosi e pei o le uila eletise, tekinolosi tipi leisa, tafatolu, herringbone, gables ma isi faʻailoga faʻapitoa faʻapitoa e mafai ona gaosia ma faia. Ina ia faʻamalieina manaʻoga o meafaigaluega tipi faʻapitoa, e mafai foi ona mamanuina e pei o afifi, sanuisi ma taʻavale meafaigaluega PDC.
(5) O le faatinoga o le oloa e mafai ona mamanuina pe valoia, ma o le oloa ua tuuina atu i ai uiga talafeagai e fetuunai ai i lona faaaogaina patino. Mo se faʻataʻitaʻiga, o le filifilia o mea faigaluega PDC lelei e mafai ona faʻaleleia atili ai le pito o le meafaigaluega; e mafai ona fa'aleleia atili le tumau o le mea faigaluega PDC.
I le faaiuga, faatasi ai ma le atinaʻeina o mea faigaluega PCD ma PDC, o le faʻaogaina o le PCD ma le PDC meafaigaluega ua vave faʻalauteleina i le tele o gaosiga.
Alamanuia e masani ona faʻaaogaina i metala e le o ni ferrous (alumi, alumini alumini, kopa, apamemea, magnesium alloy, zinc alloy, ma isi), carbide, ceramics, non-metallic mea (palasitika, paʻu malo, carbon rods, fafie, sima oloa, ma isi), mea tuʻufaʻatasia (e pei o fibre faʻamalosia palasitika CFRP, matrix uʻamea faʻapipiʻi faʻapipiʻi faʻapipiʻi faʻapipiʻi laupapa, aemaise lava MMC gaosiga faʻapitoa i le gaosiga o taʻavale faʻapitoa. carbide.
