Kodi tungsten carbide powder ndi chiyani

Tungsten carbideufa (WC) ndiye chopangira chachikulu chopangira simenti ya carbide, yokhala ndi chilinganizo chamankhwala WC.Dzina lonse ndi tungsten carbide powder.Ndi kristalo wakuda wa hexagonal wokhala ndi zitsulo zonyezimira komanso kuuma kofanana ndi diamondi.Ndi kondakitala wabwino wa magetsi ndi kutentha.Malo osungunuka ndi 2870 ℃, malo otentha ndi 6000 ℃, ndipo kachulukidwe kachibale ndi 15.63 (18 ℃).Tungstencarbidesichisungunuka m'madzi, hydrochloric acid ndi sulfuric acid, koma imasungunuka mosavuta mu nitric acid-hydrofluoric acid wosakaniza.

Tungsten carbideufa ndi ufa wotuwa wakuda ndipo ukhoza kusungunuka mumitundu yosiyanasiyana ya carbide, makamaka titanium carbide, yomwe imakhala ndi kusungunuka kwakukulu kuti ipange njira yolimba ya TiC-WC.Chigawo china cha tungsten ndi carbon ndi tungsten carbide, yokhala ndi mankhwala a W2C, malo osungunuka a 2860 ° C, malo otentha a 6000 ° C, ndi kachulukidwe wachibale wa 17.15.Makhalidwe ake, njira zokonzekera ndi ntchito zake ndizofanana ndi tungsten carbide powder.

Tungsten carbide ufa amagwiritsidwa ntchito makamaka popanga simenti ya carbide.Mutungsten carbide ufa, maatomu a kaboni amaikidwa mu mipata yatungsten zitsulolatisi popanda kuwononga chitsulo choyambirira chachitsulo, kupanga njira yokhazikika yokhazikika, choncho imatchedwanso interstitial (kapena kuika) pawiri.
