Ua hoʻolālā kūikawā ʻia ka tungsten carbide hard alloy e kūʻē i ka corrosion, abrasion, wear, fretting, sliding wear a me ka hopena i nā hana onshore a me uka a me waho a me nā lako o luna a me lalo o ke kai.

ʻO ka tungsten carbide kahi hui kemika inorganic nona ka nui o nā ʻātoma tungsten a me ke kalapona. ʻO ka tungsten carbide, i ʻike ʻia hoʻi ʻo "cemented carbide", "hard alloy" a i ʻole "hardmetal", he ʻano mea metallurgic nona ka pauka tungsten carbide (kemika: WC) a me nā mea hoʻopaʻa ʻē aʻe (cobalt, nickel, etc.).

Hiki ke kaomi ʻia a hana ʻia i loko o nā ʻano i hana ʻia, hiki ke wili ʻia me ka pololei, a hiki ke hoʻopaʻa ʻia me a hoʻopili ʻia paha i nā metala ʻē aʻe. Hiki ke hoʻolālā ʻia nā ʻano like ʻole a me nā papa 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 ʻaila a me ke kinoea a me ke kai e like me ka hana mining a me nā mea ʻokiʻoki, ka mold a me ka make, nā ʻāpana ʻaʻahu, a pēlā aku

Hoʻohana nui ʻia ka tungsten carbide i nā mīkini ʻoihana, nā mea hana pale ʻaʻahu a me ka anti-corrosion. ʻO ka tungsten carbide ka mea maikaʻi loa e pale aku i ka wela a me ka haki i nā mea paʻakikī āpau.

Hoʻohana nui ʻia ka disc valve Tungsten Carbide i ka ʻaila a me ke kinoea ma muli o ke kūpaʻa kiʻekiʻe o ka ʻaʻahu a me ke kūpaʻa kiʻekiʻe o ka corrosion.

Hoʻohana nui ʻia nā diski tungsten carbide no nā kiwikā. ʻElua diski e pili ana i kēlā me kēia me nā lua kikoʻī twp (orifice). Lana ka diski mua e kūʻē i ka diski hope e hana ana i kahi interface mated a hōʻoia i kahi sila maikaʻi. Hoʻohana ka valve ʻano diski i ʻelua mau diski Tungsten Carbide me nā lua o ke geometry kikoʻī. Hoʻohuli ʻia ka diski luna e pili ana i ka diski haʻahaʻa (lima a i ʻole ma ka actuator) e hoʻololi ana i ka nui o ka orifice. Hoʻohuli ʻia nā diski he 180 degere ma waena o ke kūlana hāmama a pani ʻia. Eia kekahi, ua hoʻolālā ʻia nā ʻili moena lapped o nā diski e hāʻawi i ka sila maikaʻi.
