He aha nā ʻano o nā ʻāpana tungsten carbide?

Hoʻokumu ʻia kekahi o nā carbide cimented kiʻekiʻe ma luna o ka carbide cemented WC-TiC-Co, nona ka TaC (NbC) mea metala makamae hiki ke hoʻomaikaʻi maikaʻi i ka paʻakikī kiʻekiʻe a me ka ikaika wela o ka alloy, a ʻo ka 0.4um ultra-fine grain alloy pauka i koho ʻia e ka vacuum as high-pressure hardness99HR3; He kūpono no nā pahi carbide kiʻekiʻe i hana ʻia me ka particleboard a me ke kila kila.

ʻO nā hiʻohiʻona o nā ʻāpana tungsten carbide: ʻo WC-TiC-TaC (NbC) Co cemented carbide nā ʻāpana tungsten carbide me 0.5 ultra-fine grains, nona ka paʻakikī kiʻekiʻe a me ke kūpaʻa wela kiʻekiʻe, anti-bonding, anti-oxidation hiki T a me ka anti-diffusion hiki, a loaʻa nō hoʻi nā hiʻohiʻona o ka hoʻonui nui ʻana i ka hoʻonui ʻana i ka ʻaʻahu a me ka maikaʻi o STF. ʻO ka carbide strip he mau waiwai piha maikaʻi loa, hoʻohana nui ʻia no ka hoʻoponopono ʻana i ke kila kiʻekiʻe, ke kila mea hana, ka hao hoʻoheheʻe paʻakikī, ka fiber aniani, nā mea hana ʻoki carbide kiʻekiʻe i hana ʻia me ka particleboard a me ke kila kila.

Hana ʻia nā ʻāpana tungsten carbide me ka WC tungsten carbide a me ka Co cobalt pauka i hui ʻia e nā ʻano metallurgical ma o ka pulverization, wili pōleʻa, kaomi a me ka sintering, ʻo nā ʻāpana alloy nui ʻo WC a me Co, a ʻo ka ʻike o ka WC a me Co i nā ʻāpana carbide cemented no nā kumu like ʻole, ʻaʻole kūlike, a ākea ka laulā. ʻO nā ʻāpana tungsten carbide kekahi o nā mea he nui i ke ʻano o nā kaola.

ʻO ke kaʻina hana o nā ʻāpana tungsten carbide ka nui o ka milling → formula e like me nā koi o ka hoʻohana → ma o ka wili pulu → ka hui ʻana → ka hoʻomaloʻo → hoʻomaloʻo → ma hope o ka sieving → hoʻohui i ka mea hoʻoheheʻe → a laila hoʻomaloʻo → sieving a laila hoʻomākaukau i ka hui ʻana → granulation → HIP kaomi → hoʻokumu → haʻahaʻa haʻahaʻa sintering → hoʻokumu ʻia (billet) ʻike hewa → ʻike ʻia (billet).

He ʻulaʻula maikaʻi loa nā ʻāpana tungsten carbide, paʻakikī kiʻekiʻe, kūpaʻa ʻaʻahu maikaʻi, modulus elastic kiʻekiʻe, ikaika compressive kiʻekiʻe, kūpaʻa kemika maikaʻi (acid, alkali, kiʻekiʻe wela oxidation resistance), haʻahaʻa haʻahaʻa haʻahaʻa, haʻahaʻa haʻahaʻa hoʻonui, thermal a me ka uila conductivity e like me ka hao a me kāna mau alloys.

ʻO ka pae noi ʻana o ka tungsten carbide strip:

1. He kūpono no ka ʻaʻahu a me ka hana ʻana i nā pahi no nā ʻōwili hao a me nā ʻōwili nickel-chromium kiʻekiʻe.

2. He kūpono no ka hana ʻana i nā mea ʻokiʻoki, nā mea hoʻopaʻa paʻi, nā kuʻi, nā make holomua uila a me nā mea hoʻoheheʻe ʻē aʻe.
