E hele a aʻo e pili ana iā HSS
ʻO nā kila kiʻekiʻe (HSS) kahi mea kila i ka paʻakikī kiʻekiʻe, a me keʻano wela, a iʻole ke kinipōpō kiʻekiʻe, aʻo keʻano he nui i ka lewa a he nui paha. Ua kapaʻia ia ma ke kila keʻokeʻo.
ʻO kahi kila kiʻekiʻeʻoi aku kahi kila hoʻohui me kahiʻano paʻakikī e loaʻa ana i nā mea e like me ka mea e like me keʻano he chromitium, chromium, chromium ʻO ka nui o nā helu alloying e loaʻa ana ma kahi o 10 a 25%. Hiki iā ia ke mālama i ka paʻakikī kiʻekiʻe ma lalo o ka wela wela (e pili ana i ka 500 ℃) i luna o ka wikiwiki kiʻekiʻe.ʻO kēia ka mea paʻakikī loa. A me ka wana wana e like me ke kaulahao a me ka haʻahaʻa o ke kauʻana, ma keʻano he nui loa, ke palena nei ka matalming i nā mea hana uila. A me nā kila kiʻekiʻe ma muli o ka paʻakikīʻulaʻula maikaʻi, e hana i nā pohō o ka mea momona o ka carbon.
Hoʻohana nuiʻia ka pahu kumukūʻai wikiwiki e hana i nā hana koʻikoʻi a me nā pono kīwī, akā e like me ka huliʻana i nā mea hoʻonani kiʻekiʻe, a me nā pōpō i loaʻa iā ia nā mea paʻapaʻa.
Hele mai a aʻo e pili ana i nā kila tungten
ʻO ka Steel Tuel (Carbide) he mau mea nui o nā waiwai maikaʻi loa e like me ka paʻakikī, e like me ka nui o ka paleʻana a me ka paleʻana i ka nui o ka nui o 500 ℃.
ʻO nā kila wahine,ʻo ia nā mea nui loa he nui nā mea nui a me nā condert, nā moʻokāki a me ka heihei ma nāʻano heihei, a no laila, he kapaʻiaʻo Tereketnals
ʻO nā mea kūʻai akuʻo Tungsten kahi mea i hana hewaʻia e loaʻa ana ma ka liʻiliʻi o hoʻokahi mea hoʻokele kaʻaila. ʻO nā kākela hoʻopunipuni, carbie carbie, niibium carbide, titnium carbide, a me nā cantalum carbide, a me ke kaʻa kaʻa he mea maʻamau nā mea kila tungsten. ʻO ka nui o ka palaoa o ka carbidetion i ka'āpana (a iʻole ka phase) ma ka laulā o 0.2-10 mau microns, a me nā microns curbide ʻO nā metala ka huiʻana o nā metala maʻamau i nā metala maʻamau, maʻamau corbat a me nickel. No laila, aia nā alloys-corbatt allys, trungsten-nickel alloys a me nā kumulāʻau cubal
ʻO ka hana hewaʻana i ka hana hewa e kaomi i ka pauka i loko o kahi pahu, a laila i loko o kahi manawa he nui) a hoʻopaʻa i ka manawa i loaʻa ai i kahi manawa kūpono.
①Tungsten a me Corbat Canam carbide
ʻO ka mea nui ka nui o ka mea nui o ka carbide (wc) a me Binder Cobelt (CO). Ua hakuʻia ka papa o ka "YG" ("paʻakikī, COPELTT" i Hanyu Pinyin) Ka laʻana,ʻo YG8,ʻo ia ka mea o ke kumuʻo Wco = 8% a me ke koena o ka carbie carbie.
②Tungsten
ʻO nā mea nui he nui nā mea nui o ka carbied Ua hakuʻia ka papa o ka "yt" ("paʻakikī, titanium" i Hanyu Pinyin) ʻO kahi laʻana, YT15,ʻo keʻano o ka Tic = 15%,ʻO ke koena o ka cubtenu nui a me nā corbat
③Tungsten-Titanium-Tantalim (Noibium) Carbide
ʻO nā mea nui he nui nā mea nui,ʻo Titanium Carbide,ʻo Tantalum Cabide (a iʻole Noibium Carbide) a me Curbat. Ua kapaʻiaʻo ia i kēiaʻano o ka Carbide i kapaʻiaʻo ka carbide maʻamau a iʻole ke kālaiʻana. ʻO ka papa helu o ka "YW" ("paʻakikī" a "miliona" ma Hanyu Pinyin a me ka yw1.
Heʻano nui o nā kila Truelst Ua hoʻohana nuiʻia ka paleʻana i ka pale i nā mea likeʻole, e like me nā mea hana e like me nā mea hana e like me nā mea pāʻani hou.
