Tungsten carbide(WC) ke motsoako o entsoeng ka refractory metal tungsten le non-metallic carbon, e nang le litšoaneleho tsa "high density", boemo bo phahameng ba ho qhibiliha, matla a phahameng, boima bo phahameng, ho hanyetsa mocheso o phahameng, ho hanyetsa kutu, ho hanyetsa ho apara le motlakase o motle le conductivity e ntle ea mocheso. , kahoo ke sesebelisoa se loketseng sa carbide.
Leha ho le joalo, ka lebaka la bothata ba brittleness le boima bo fokolang ba phofo e bonolo ea WC, hangata hoa hlokahala ho eketsa palo e loketseng ea binder e kang cobalt (Co), nickel (Ni), chromium (Cr), molybdenum (Mo), titanium ( Ti), koporo (Cu) le likarolo tse ling ha ho etsoa lisebelisoa tse phahameng tsa carbide.
Haholo-holo, ka phofo ea WC e le karolo e thata le Co e le karolo ea binder e loketseng lisebelisoa tsa ho itšeha.E na le conductivity e ntle ea mocheso, e ntle bakeng sa ho khaola mocheso oa mocheso ho tloha ntlheng ea sesebelisoa, ho fokotsa mocheso oa ntlha le ho qoba ho chesa le ho nolofatsa ntlha ea sesebelisoa;e na le matla a phahameng a flexural le ho tiea ha tšusumetso, e ka fokotsang ka katleho monyetla oa ho phunya ha seha;e na le khanyetso e ntle haholo ea ho itšeha (ho feta hole le tšepe e lebelo le holimo), 'me e khona ho sila bohale bo bohale.
lehare la carbide le entsoeng ka samentee nang le phofo ea WC e le karolo e thata le Ni ha karolo ea bonding e loketse ho feta likarolo tse hanyetsanang le ho bola.Ho hanyetsa ha eona ho matla ho feta lisebelisoa tsa tungsten le cobalt carbide, ho etsa hore e tšoanelehe bakeng sa lits'ebetso libakeng tse nang le mecha ea litaba e fapaneng e senyang.Ntle le moo, litiiso tsa carbide tsa WC-Ni li boetse li loketse lits'ebetso ka mocheso o tlase, mocheso o phahameng, vacuum le khatello e phahameng.
E entsoe ka WC, TiC le Co e na le litšobotsi tsa boima bo phahameng, ho hanyetsa mocheso o motle, matla a matla a ho hatella, ho hanyetsa oxidation e ntle, ho se sebetse hantle ha mocheso le tse ling, tse loketseng ho sebetsa tšepe.
Ho lokela ho hlokomeloa hore lipontšo tse itseng tsa 'mele tsamotsoako o thatae tla fetoha ka karolelano e fapaneng ea lisebelisoa tse tala.Haeba lera kapa likarolo tse ngata tsa carbide, carbide le metsoako e meng e thata ea refractory e fafatsoa holim'a motsoako o thata, ho hanyetsa ho apara ho phahameng le ho tiea ho hoholo ha motsoako ho tla lumellana haholoanyane, kahoo ho loketse ho itšeha ka lebelo le phahameng. .
