ʻO Tungsten carbide kahi hui kemika inorganic i loaʻa nā helu o nā tungsten a me nā ʻātoma kalapona. ʻO Tungsten carbide, i ʻike ʻia ʻo "cemented carbide", "hard alloy" a i ʻole "hardmetal", he ʻano mea metallurgic e loaʻa ana i ka pauka tungsten carbide (kemu kumu: WC) a me nā mea hoʻopili ʻē aʻe (cobalt, nickel. etc.).

Hōʻike ka lāʻau alakaʻi ʻo Tungsten carbide i ka paʻakikī kiʻekiʻe a me ka ikaika o ka rupture transverse, a ʻoi aku ka maikaʻi o ka hana ʻana i ka pale ʻana i ka abrasion a me ka corrosion, e hiki ai ke hoʻohana nui ʻia i nā ʻoihana he nui.

E hoʻohana nui ʻia ka lima tungsten carbide alakaʻi no ke kākoʻo ʻana i ke kākoʻo, aligning, anti-thrust a me ke sila o ke axle o ke kaʻa, centrifuge, pale a me ka mea hoʻokaʻawale o ka pauma uila i loko o nā kūlana hana maikaʻi ʻole o ke kiʻekiʻe kiʻekiʻe o ka holo ʻana, ke one lash abrasion a me ke kinoea kino i loko o ka māla aila, e like me ka paheʻe lima lima a me ka lima lima axle.

Hoʻohana ʻo Tungsten carbide bush i nā mea maka a me nā mea kōkua e like me ka tungsten carbide saturated, kiʻekiʻe-maʻemaʻe ultra-fine cobalt pauka, ka hui ʻana o ke kalapona pololei, ka wili pōleʻa kiʻi, ka hoʻoulu ʻana i ka maloʻo, ke kaomi pololei ʻana, ka sintering digital degreasing a me ke kaomi sintering pilikino post-processing a me nā kaʻina hana metallurgy holomua ʻē aʻe. Hoʻohana nui ʻia ka lima paʻa paʻa i ka ʻoihana valve kūikawā, me ke ola lawelawe lōʻihi a me ka maikaʻi hilinaʻi.
