Nā ʻokoʻa ma waena o Tungsten a me Tungsten Carbide

I ka ʻoihana hou, ua lilo nā huahana tungsten carbide i mea mea hana kaulana. A ʻaʻole hoʻohana wale ʻia ka tungsten no ka pā. Ma kēia ʻatikala, e kamaʻilio mākou e pili ana i nā ʻokoʻa ma waena o ka tungsten a me ka tungsten carbide. E hōʻike ana kēia ʻatikala penei:

1. He aha ka tungsten?

2. He aha ka tungsten carbide?

3. Nāʻokoʻa ma waena o ka tungsten a me ka tungsten carbide.

He aha ka tungsten?

Ua ʻike mua ʻia ʻo Tungsten i ka makahiki 1779, a ua kapa ʻia ʻo ia he "pohaku kaumaha" ma Suedena. Loaʻa i ka Tungsten nā helu heheʻe kiʻekiʻe loa, ka helu hoʻonui haʻahaʻa haʻahaʻa, a me ke kaomi mahu ma waena o nā metala. Loaʻa iā Tungsten ka elasticity maikaʻi a me ka conductivity.

He aha ka tungsten carbide?

ʻO Tungsten carbide kahi hui o tungsten a me carbon. Ua ʻike ʻia ʻo Tungsten carbide ka lua o ka mea paʻakikī loa ma ka honua, ma hope o ke daimana. Ma waho aʻe o ka paʻakikī, ʻoi aku ka maikaʻi o ka tungsten carbide, ka pale ʻana i ka corrosion, ka haʻalulu, a me ka lōʻihi.

ʻO nā ʻokoʻa ma waena o ka tungsten a me ka tungsten carbide

E kamaʻilio mākou e pili ana i ka ʻokoʻa ma waena o ka tungsten a me ka tungsten carbide ma kēia mau ʻano:

1. Modulus elastic

Loaʻa iā Tungsten kahi modulus elastic nui o 400GPa. Eia naʻe, ʻoi aku ka nui o ka tungsten carbide ma kahi o 690GPa. ʻO ka hapa nui o ka manawa, pili ka paʻakikī o nā mea i ka modulus elastic. ʻO ka modulus kiʻekiʻe o ka elasticity o ka tungsten carbide e hōʻike ana i ka paʻakikī kiʻekiʻe a me ke kūpaʻa kiʻekiʻe i ka deformation.

2. ʻO ka hoʻoheheʻe ʻana

ʻO ka modulus shear ka lākiō o ke koʻikoʻi ʻāwili i ke kānana ʻāwili, ʻo ia hoʻi i kapa ʻia ʻo ka modulus o ka rigidity. ʻO ka mea maʻamau, ʻo ka hapa nui o nā kila he modulus shear a puni 80GPa, ʻelua mau manawa ka tungsten, a ʻekolu mau manawa ka carbide tungsten.

3. Tensile hua ikaika

ʻOiai ʻo ka tungsten a me ka tungsten carbide ka paʻakikī a me ka paʻakikī, ʻaʻohe o lākou ikaika kiʻekiʻe. ʻO ka maʻamau, ʻo ka ikaika tensile yield o tungsten ma kahi o 350MPa, a ʻo ka tungsten carbide ma kahi o 140MPa.

4. ʻO ke kau wela wela

He mea koʻikoʻi ka conductivity thermal i ka wā e hoʻohana ʻia ai ka mea ma kahi ʻano wela kiʻekiʻe. ʻOi aku ka nui o ka conductivity thermal ma mua o ka tungsten carbide. Loaʻa i ka Tungsten ka paʻa wela, no laila ua kūpono ia no kekahi mau mea wela, e like me nā filament, tubes, a me nā coils hoʻomehana.

5. Oolea

He 66 ka paʻakikī o ka tungsten, ʻoiai ʻo ka tungsten carbide ka paʻakikī o 90. ʻO ka tungsten carbide ka tungsten a me ke kalapona, no laila ʻaʻole wale nā ​​mea maikaʻi o ka tungsten, akā loaʻa nō hoʻi ka paʻakikī a me ka paʻa kemika o ke kalapona.

Inā makemake ʻoe i nā huahana tungsten carbide a makemake ʻoe i ka ʻike hou aʻe a me nā kikoʻī, hiki iā ʻoe ke CONTACT US ma ke kelepona a i ʻole leka uila ma ka hema, a i ʻole SEND US MAIL ma lalo o ka ʻaoʻao.
