Tungsten carbide kumu waiwai maka

ʻO Tungsten carbide pauka (WC) ka mea nui no ka hana ʻanatungsten carbide, ʻano kimeka WC.piha inoa , tungsten carbide pauka he ʻeleʻele hexagonal kristal, metala luster, paakiki a me daimana like me ka maikai conductor o ka uila a me ka wela.Ka helu heheʻe 2870 ℃, kahi e hoʻolapalapa ai 6000 ℃, pili pili 15.63 (18 ℃).ʻAʻole hiki ke hoʻoheheʻe ʻia ʻo Tungsten carbide i ka wai, hydrochloric acid a me sulfuric acid, hiki ke hoʻoheheʻe ʻia i ka waikawa nitric - hydrofluoric acid i hui pū ʻia.He palupalu ka tungsten carbide, inā hui pū ʻia me kahi liʻiliʻi o ka titanium, cobalt a me nā metala ʻē aʻe, hiki iā ia ke hōʻemi i ka brittleness.Hoʻohana ʻia ma ke ʻano he mea ʻoki kilatungsten carbide, Hoʻohui pinepine ʻia ka titanium carbide, tantalum carbide a i ʻole ka hui ʻana o ia mau mea e hoʻomaikaʻi ai i ka hiki anti-explosive.

Paʻa nā waiwai kemika o ka tungsten carbide.Hoʻohana nui ʻia ka pauka tungsten carbide i ka hana ʻana o ka carbide cemented.I loko o ka pauka tungsten carbide, ua hoʻokomo ʻia nā ʻātoma kalapona i loko o nā interstices o ka tungsten metala lattice a ʻaʻole e luku i ka lattice metala kumu, e hana ana i kahi hopena paʻa interstitial, no laila ua ʻike ʻia ʻo ia ʻo ka gap-filling (a i ʻole insertion).

ʻO ka hiʻohiʻona o ka pauka tungsten carbide he hina, me ka hoʻonui ʻana o ka nui o ka huahana, ke kala mai ka pōʻeleʻele a i ka mālamalama.Pono ka waihoʻoluʻu a kūlike, me ka ʻike ʻole ʻia.
