Ka helu ʻana o ka nui o ka palaoa Tungsten carbide

Ua kapa ʻia kēia ʻano o ka alloy YG type alloy.ʻO ke ʻano maʻamau o WC-Co alloy keʻokeʻo he ʻelua-phase alloy i haku ʻia me ka polygonal WC phase a me ka hoʻopaʻa ʻana o Co. I kekahi manawa ma lalo o 2% o nā mea ʻē aʻe (tantalum, niobium, chromium, vanadium)nā kalaponaHoʻohui ʻia ma ke ʻano he mea hoʻohui i ka ʻoki ʻoki a i ʻole ke kiʻi make e hoʻonui i ke ola lawelawe o ka mea hana.Eia naʻe, ʻaʻole ia e hoʻololi i ka hana maʻamau o ka huila, a aia nō ia i ke ʻano WC-Co o ka carbide cemented.Ke hoʻohālikelike ʻia me nā carbide cemented ʻē aʻe me ka ʻike cobalt like, ʻo kēia ʻano o ka alloy ka ikaika flexural kiʻekiʻe, ka ikaika compressive, ka paʻakikī o ka hopena a me ka modulus elastic, a me kahi coefficient hoʻonui laina liʻiliʻi.

Wahi atungsten carbideʻO ka palaoa, ua māhele pinepine ʻia kēia ʻano carbide cemented i ʻekolu mau ʻāpana: ka palaoa coarse, ka palaoa waena a me ka palaoa maikaʻi.Me ka hoʻomohala ʻana o nā mea i hana ʻia acarbide simaʻO nā kaʻina hana, ua ulu nui nā hua WC o WC-Co i nā hopena ultra-coarse a ultra-fine.
