Tongten Carbide, WC, ko tungstarbide semicarinbide, w2c, carbin sunadarai ne mai guba da carbon, mai kama da Carbon, mai kama da Carbide. Colloquicly, tungten carbide sau da yawa ana kiranta Carbide.
Kayan sunadarai
Akwai biyu da kyau halayen mahadi na tungsten da carbon, WC da W2C. Dukansu mahadi na iya kasancewa a cikin coftings da rabbai na iya dogaro da hanyar da aka shafi, ga misali
Za'a iya shirya WC ta hanyar amsawa na ƙarfe da carbon a 1400-2000''C. Sauran hanyoyin sun haɗa da tsarin gado na kwastomomi wanda ya koma ƙarfe ko ko dai karfe 3 tare da H2 tsakanin 900 da 1200'C. Hanyoyin ajiya na kayan maye da aka bincika waɗanda aka bincika sun haɗa da:
Tungten Hexachloride tare da Hydrogen, kamar yadda ragwident wakili da methane a matsayin tushen carbon a 670'C
Wcl6 + H2 + ch4 → WC + 6hcl
Maimaita taken Tunsten Hexaflumide tare da Hydrogen kamar yadda aka rage wakili da methanol kamar tushen carbon a 350'C
Wf6 + h2 + ch3oh → wc + 6hf + h2o
A babban yanayin zafi WC ya bazu zuwa Tungogten da Carbon da wannan na iya faruwa a lokacin zafin zafin jiki mai yawa (hvof) da kuma babban makamashi.
