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 ʻo Tungsten carbide bearing bush i ka paʻakikī kiʻekiʻe a me ka transverse rupture ikaika, 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 tungsten carbide bearing bush sleeve no ka rotating support, aligning, anti-thrust and seal of the axle of motor, centrifuge, protector and separator of the submerged electric pump in the adverse working conditions of high speed rotating, sand lash abrasion and gas corrosion in the oil field, like slide bearing sleeve and seal axle sleeve.

Hoʻohana ʻia ka lima carbide cemented i nā mea maka a me nā mea kōkua e like me ka saturated tungsten carbide, high-purity ultra-fine cobalt powder, carbon blending precise, tilt ball milling, vacuum stirring drying, precision pressing, digital degreasing sintering and pressure sintering personalized post-processing and other advanced powder metallurgy. Hoʻohana nui ʻia ka lima paʻa paʻa i ka ʻoihana pamu 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.
