ʻO ka tungsten carbide (paʻakikī paʻakikī) he mau waiwai maikaʻi loa e like me ka paʻakikī kiʻekiʻe, ke kūpaʻa ʻana, ka ikaika maikaʻi a me ka paʻakikī, ka pale ʻana i ka wela a me ka pale ʻana i ka corrosion, ʻoi aku kona paʻakikī kiʻekiʻe a me ke kūpaʻa ʻana, ʻoiai ma kahi mahana o 500 ℃. , a loaʻa nō ka paʻakikī kiʻekiʻe ma 1000 ℃.

ʻO Tungsten carbide, nā mea nui he tungsten carbide a me ka cobalt, ʻo ia ka 99% o nā mea āpau, 1% nā metala ʻē aʻe, no laila ua kapa ʻia ʻo tungsten steel, ʻike ʻia hoʻi he carbide cemented, a ua manaʻo ʻia ʻo ia nā niho o ka ʻoihana hou. .

ʻO Tungsten carbide kahi mea i hoʻopaʻa ʻia i haku ʻia me hoʻokahi carbide metala.ʻO Tungsten carbide, cobalt carbide, niobium carbide, titanium carbide, a me tantalum carbide nā mea maʻamau o ke kila tungsten.Aia ma waena o 0.2 a me 10 microns ka nui o ka ʻāpana carbide, a ua hoʻopaʻa pū ʻia nā ʻāpana carbide me ka hoʻohana ʻana i kahi mea hoʻopaʻa metala.ʻO ka metala paʻa ka mea maʻamau he metala hui hao, a hoʻohana mau ʻia ka cobalt a me ka nickel.No laila, aia nā tungsten cobalt alloys, tungsten nickel alloys a me tungsten titanium cobalt alloys.

ʻO ka tungsten carbide sintering ʻo ia ke kaomi ʻana i ka pauka i kahi hakahaka, a laila e wela iā ia i loko o kahi umu sintering i kahi mahana (sintering temperature), a mālama iā ia no kekahi manawa (manawa paʻa), a laila hoʻomaha ia, i loaʻa ai. ka hana i makemake ʻia o nā mea kila tungsten.
