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

Hōʻike ʻo Tungsten carbide bearing bush i ka paʻakikī kiʻekiʻe a me ka transverse rupture ikaika, a ʻoi aku ka maikaʻi o ka hana ma ke kūʻē 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 tungsten carbide bearing bush sleeve no ka hoʻololi ʻana i ke kākoʻo, aligning, anti-thrust a me ke sila o ke axle o ka kaʻa, centrifuge, pale a me ka mea hoʻokaʻawale o ka pauma uila i loko o nā kūlana hana ʻino o ka wikiwiki kiʻekiʻe, abrasion lash. a me ka ʻino kinoea i loko o ke kahua ʻaila, e like me ka lima paheʻe, ka lima axle kaʻa a me ka lima axle sila.

Hoʻohana ʻia ka lima carbide cemented i nā mea maka a me nā mea kōkua e like me ka tungsten carbide saturated mua, ka pauka cobalt ultra-fine kiʻekiʻe, ka hui ʻana o ke kalapona pololei, ka wili pōleʻa kiʻi, ka hoʻomaloʻo ʻana i ka hoʻomaloʻo ʻana, ke kaomi pololei ʻana, ka sintering digital degreasing a me ka sintering hoʻopaʻa pono ʻana i ka post-processing a nā kaʻina hana metallurgy pauda holomua ʻē aʻe.Hoʻohana nui ʻia ka lima paʻa paʻa i ka ʻoihana pahū kūikawā, me ke ola lawelawe lōʻihi a me ka maikaʻi hilinaʻi.

Ke hana nei nā lima lima o ka nahele i loko o kahi ʻano abrasive ma muli o ka hoʻololi ʻana, friction, etc.

ʻO ka lima tungsten carbide bushing me ka ʻaʻahu a me ke kūpaʻa ʻana a me ka paʻakikī haʻihaʻi kiʻekiʻe no ke koi ʻana i ka axial thrust, a hiki ke hoʻokō i nā koi maʻamau API maʻamau.
