Iyo kristu ya silikoni karubide ikura, "ibidukikije" by'aho kristu ikura hagati y'aho hagati y'ibuye ry'agaciro n'inkombe biratandukanye, ku buryo imbaraga za kristu ku nkombe ziyongera, kandi inkombe ya kristu byoroshye gutanga "inenge nyinshi" bitewe n'ingaruka za girafu "carbone", uburyo bwo gukemura ikibazo cy'inkombe cyangwa kongera ubuso bukora neza bw'aho hagati (birenga 95%) ni ingingo y'ingenzi mu bya tekiniki.
Uko inenge nini nka "microtubules" na "inclusions" zigenzurwa buhoro buhoro n'inganda, bigatera imbaraga kristu za silicon carbide "gukura vuba, muremure kandi mugari, no gukura", "inenge nyinshi" zigaragara cyane, kandi uko uburebure n'ubugari bwa kristu za silicon carbide byiyongera, "inenge nyinshi" zizaba zikubye kabiri n'ubugari bwa kare.
Gukoresha tantalum carbide TaC coating ni ugukemura ikibazo cy’inkombe no kunoza ireme ry’ikura rya kristu, ikaba ari imwe mu nzira z’ingenzi zo “gukura vuba, gukura neza no gukura”. Mu rwego rwo guteza imbere iterambere ry’ikoranabuhanga mu nganda no gukemura ikibazo cyo “gutumiza” kw’ibikoresho by’ingenzi, Hengpu yateye imbere mu gukemura ikoranabuhanga rya tantalum carbide coating (CVD) kandi igera ku rwego mpuzamahanga ruteye imbere.
Gusiga TaC ya karuboni ya Tantalum, ukurikije uko ikorwa, ntabwo bigoye, hamwe no gusiga, CVD n'ubundi buryo biroroshye kugeraho. Uburyo bwo gusiga, gukoresha ifu ya karuboni ya tantalum cyangwa icyabanjirije, kongeramo ibintu bikora (muri rusange icyuma) n'ikintu gihuza (muri rusange polymer y'urunigi rurerure), bitwikiriwe ku buso bwa graphite substrate itwikiriwe ku bushyuhe bwinshi. Dukurikije uburyo bwa CVD, TaCl5+H2+CH4 yashyizwe ku buso bwa graphite matrix kuri 900-1500℃.
Ariko, ibipimo by'ibanze nko kureba kristale ya tantalum carbide deposition, ubugari bwa filime imwe, kurekura stress hagati yo gusiga na grafiti matrix, icyuho cy'ubuso, nibindi, biragoye cyane. Cyane cyane mu mikurire ya crystal, ubuzima buhamye ni cyo gipimo cy'ingenzi, ni cyo kigoye cyane.
