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.).
Tungsten Carbide - Loaʻa ʻia nā carbide tungsten cemented mai kahi pākēneka kiʻekiʻe o nā ʻāpana tungsten carbide i hoʻopaʻa ʻia e kahi metala ductile. ʻO nā mea hoʻopaʻa maʻamau i hoʻohana ʻia no nā bushings he nickel a me cobalt. ʻO nā waiwai i loaʻa e hilinaʻi ʻia ma ka matrix tungsten a me ka pākēneka o ka mea hoʻopaʻa (maʻamau 6 a 15% ma ke kaupaona no ka leo).

Hiki ke paʻi ʻia a hana ʻia i nā ʻano hana maʻamau, hiki ke wili ʻia me ka pololei, a hiki ke hoʻopaʻa ʻia me nā metala ʻē aʻe. Hiki ke hoʻolālā ʻia nā ʻano like ʻole a me nā māka o ka carbide e like me ka mea e pono ai no ka hoʻohana ʻana i ka noi i manaʻo ʻia, me ka ʻoihana kemika, ka aila a me ke kinoea a me ke kai e like me ka mining a me ka ʻoki ʻana i nā mea hana, mold a make, aahu i nā ʻāpana, etc.

Ma muli o nā noi like ʻole o nā mea hoʻohana, hana pinepine ʻia nā kumulāʻau tungsten carbide i nā māka tungsten carbide like ʻole. ʻO ka moʻo nui ʻelua o ka papa tungsten carbide ʻo YG (cobalt) series a me YN (Nickel) series. ʻO ka ʻōlelo maʻamau, ʻoi aku ka ikaika o ka nahā ʻana o nā lāʻau tungsten carbide YG series, ʻoiai ʻo YN series tungsten carbide bush e pale aku i ka corrosion ma mua o ka mua.

Hōʻike ka lima o ka pahu tungsten carbide i ka paʻakikī kiʻekiʻe a me ka ikaika o ka uhaʻi 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 shaft no ke kākoʻo 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. kinoea corrosion i loko o ka aila kahua, e like me ka slide bearing lima, motor axle lima a sila sila axle lima.
