Ke eng ea boron carbide (b4c) e sebelisitsoeng?
Bakeng sa boima ba eona:
Theol the ke senotlolo sa boron carbide, tse khahlisang Moqapi kapa moenjiniere, ho na le thata ho hanyetsa. Mehlala e tloaelehileng ea tšebeliso e nepahetseng ea thepa ena e kenyeletsa: li-paddle; Ka bomong le koloi antisping Armi e hlabang; Grit e jala li-nouzles; Li-notter tse phahameng tsa metsi tsa jete tse phahameng haholo; Scratch le ho roala makhapetla a thibelang; Ho rema lisebelisoa ebe lia shoa; Li-ahlatic; Metal Matrix Composites; Ka har'a makoloi a likoloi.
Bakeng sa ho ba thata:
Boron Carbide e sebelisoa ho ba bakuli ba sireletsang ho hanela tšusumetso ea lintho tse bohale bo kang likulo, setsi sa motlakase le li-qhobosheane. Hangata e kopantsoe le li-commates tse ling nakong ea ts'ebetso. Ka lebaka la ho ba le matla a eona a phahameng, Armor Armor ho thata hore bullet e kenelletse. Lintho tse bonahalang li ka monya matla a li-bullet ebe o hlakola matla a joalo. Bokaholimo bo ne bo tla hlaba ka likarolo tse nyane le tse thata hamorao. U sebelisa lisebelisoa tsa boron carbide, masole, litanka le lifofane li ka qoba likotsi tse mpe tsa likulo ho likulo.
Bakeng sa thepa e meng:
Boron carbide ke thepa e sebelisang lijalo tsa nyutlelie bakeng sa bokhoni ba eona ba ho kenella ha eona, theko e tlase le e ngata. E na le karolo ea ho kena-kenana le eona. Bokhoni ba Boron Carbiside ho amohela li-neuctide tse telele ho etsa hore li be monate limelong tsa motlakase tsa nyutler. Boron Carbide e sebelisetsoa thebe, e le molamu oa taolo oa mohiruoa oa nyutlelie le a theosa li-pellets semeleng sa matla a nyutlelie.
