Chida chapadera chozungulira cha tayala

Chifukwa cha mawonekedwe apamwamba pakati pa diamondi ndi zitsulo wamba ndi aloyi, tinthu tating'ono ta diamondi sitingalowe ndi kulowerera pang'ono, osagwirizana kwenikweni. Muukadaulo wopanga zachikhalidwe, tinthu tating'onoting'ono timangodalira mphamvu zamagetsi zomwe zimapangidwa ndi kuzizira kwa matrix kuti tiike mu matrix azitsulo a matrix, koma osapanga mgwirizano wolimba wamankhwala kapena chitsulo chazitsulo, chifukwa cha tinthu tating'onoting'ono. kudzipatula ku matrix chitsulo pazantchito, zomwe zimachepetsa kwambiri moyo wamasewera ndi magwiridwe antchito a zida zam diamondi. Pazida zambiri zomwe zimayikidwa, kuchuluka kwa diamondi kumakhala kotsika, ndipo kuchuluka kwa maamondi okwera mtengo kumataika mu tchipisi tota. Lin Zengdong adatsogola kugwiritsa ntchito ukadaulo wa diamondi pamwamba pakupanga miyala ya diamondi ndi zinthu zambiri zatsopano, monga kapangidwe kabwino ka matenthedwe, kukhazikika kwamphamvu yamafuta, kukonza magwiridwe ake oyamba amthupi ndi mankhwala, kukonza mawonekedwe ake a zitsulo kapena aloyi yankho, ndi zina zambiri.
Kupangidwa kwazitsulo kwa diamondi kwakopa chidwi cha opanga zida zamalonda kunyumba ndi kunja kuyambira 1970s. *** Ngakhale zatsimikiziridwa kuti zitsulo zina monga tungsten (osati oxidized) zimatha kupanga WC wosanjikiza pamwamba pa diamondi pamoto wotsika kwambiri (pafupifupi 800 ℃), mphamvu yabwino yolumikizirana imatha kupezeka potentha kwa ola limodzi pansi vacuum ndi pamtunda wa 600 ℃ malinga ndi momwe amagwiritsidwira ntchito kuti azindikire mawonekedwe a diamondi asanafike. Malinga ndi zoyipa za zida zodula zomwe zimagwiritsidwa ntchito masiku onse, ndizokayikitsa kuti zitsulo zoterezi zimapangidwa pamalo a diamondi ngati ziwotedwa kwa mphindi pafupifupi zisanu ndi 900 ℃ osakwanira kapena osavomerezeka. Chifukwa ngati ma atomu achitsulo (Ti, V, Cr, ndi zina) ndi otukuka pa diamondi kapena mawonekedwe ake amafika pophatikizana ndi chitsulo cha diamondi ndi diamondi ndi njira yophatikizira atomiki. Malinga ndi kutentha komwe kumagwiritsidwa ntchito kukanikiza kutentha komanso nthawi yochepa, njirayi ndiyosakwanira. Pansi pa cholimba cholimba gawo (nthawi zina pamakhala mphamvu zochepa komanso chitsulo chosungunuka kapena chitsulo chamadzi), mphamvu yolumikizana ndi mankhwala a metrix kapena diamondi ndi yofooka kwambiri kapena sizingapangike konse.
Kupangira zitsulo kusanachitike sikuti cholinga chomaliza, koma njira imodzi yokha yodziwira zophatikizira zachitsulo ndi matrix chitsulo. Dayimale yophimbayo ikasokonekera kukhala mano a ma saw (kubowola), diamondi yotulutsidwa papulaloyo itayika, ndipo mawonekedwe a maenje otsalawo ndi osalala kwambiri, zomwe zikuwoneka kuti zikuwonetsa kuti diamondi ndi matrix sizinafike pamlingo kuphatikizika kwa mankhwala. Chifukwa chake, ngakhale mutakhala kuti chitsulidwe chamtengo wapatali cha diamondi chitha, njira yolumikizira ufa yokhala ndi zitsulo singathe kuzindikira kuphatikiza pakati pa diamondi ndi matrix.
