Tungsten carbideKo te paura (WC) te mea matua mo te hanga o te carbide cimented, me te tikanga matū WC.Ko te ingoa katoa ko te tungsten carbide paura.He karaihe hexagonal pango me te kanapa whakarewa me te pakeke rite ki te taimana.He pai te kawe hiko me te wera.Ko te ira whakarewa he 2870 ℃, te ira koropupū he 6000 ℃, a ko te kiato whanaunga he 15.63 (18 ℃).Tungstenkaraihahe tarewa i roto i te wai, te waikawa pūmāota me te waikawa pungatara, engari he ngawari ki te wairewa i roto i te waikawa nitric-hydrofluoric waikawa whakauru.
Tungsten carbideKo te paura he paura hina pouri, ka taea te rewa i roto i nga momo carbide, ina koa ko te titanium carbide, he nui te whakarewatanga hei hanga i te otinga totoka TiC-WC.Ko tetahi atu pūhui o te tungsten me te waro ko te tungsten carbide, me te tauira matū o te W2C, te rewa o te 2860°C, te ira koropuke o 6000°C, me te kiato whanaunga o 17.15.Ko ona ahuatanga, tikanga whakarite me ona whakamahinga he rite ki te paura tungsten carbide.
Tungsten carbide paura te nuinga whakamahia i roto i te hanga o te carbide sima.I rototungsten carbide paura, ka mau nga ngota waro ki nga waahi o tekonganuku tungstenwhakahoahoa me te kore e whakangaro i te kurupae whakarewa taketake, ka hanga he otinga totoka interstitial, no reira ka kiia hoki he pūhui interstitial (whakauru ranei).
