Ka waiwai kino o ka tungsten carbide

Loaʻa i ka ʻenehana hou kahi ākea ākea o ka hoʻohana ʻana no ka alloy kū hoʻokahi tungsten-kobalta. No ke aha i kaulana ai? Eia kekahiwaiwai kino o ka tungsten carbide. Ma hope o ka heluhelu ʻana i kēia pauku e ʻike ʻoe i nā kikoʻī hou aku e pili ana iā ia.

ʻoʻoleʻa.

ʻIke mākou a pau ʻo ke daimana kekahi o nā mea kūlohelohe paʻakikī loa o ka honua. ʻOiai ʻo ka paʻakikī o ka tungsten carbide ka lua i ke daimana.ʻO ka paʻakikī kekahi o nā waiwai mechanical nui o ka carbide cemented. Me ka hoʻonui ʻana o ka ʻike cobalt i loko o ka huila a i ʻole ka piʻi ʻana o ka nui o ka carbide grain, e emi ana ka paʻakikī o ka alloy. Eia kekahi laʻana, i ka piʻi ʻana o ka cobalt content o ka ʻoihana WC-Co mai 2% a i 25%, e emi ana ka paʻakikī o ka alloy mai 93 a hiki i 86. No kēlā me kēia 3% o ka hoʻonui ʻana o ka cobalt, e emi ana ka paʻakikī o ka alloy i ka 1 degere. ʻO ka hoʻomaʻemaʻe ʻana i ka nui o ka palaoa o ka tungsten carbide hiki ke hoʻomaikaʻi maikaʻi i ka paʻakikī o ka alloy.

Ka ikaika kulou.

E like me ka paʻakikī, ʻo ka ikaika kulou kekahi o nā waiwai nui o ka carbide cemented. Nui nā mea koʻikoʻi e pili ana i ka ikaika kulou o ka alloy, ma ka ʻōlelo maʻamau, piʻi ka ikaika kulou o ka alloy me ka piʻi ʻana o ka ʻike cobalt. Eia nō naʻe, ke ʻoi aku ka nui o ka ʻike cobalt ma mua o 25%, e emi ana ka ikaika kulou me ka piʻi ʻana o ka ʻike cobalt. E pili ana i ka ʻenehana WC-Co alloy, piʻi mau ka ikaika kulou o ka alloy me ka hoʻonui ʻana o ka ʻike cobalt i ka pae o 0-25%.

Ka ikaika compressive.

ʻO ka ikaika compressive o ka carbide cemented e hōʻike ana i ka hiki ke pale aku i ka ukana kaomi.Me ka hoʻonui ʻana o ka cobaltmaʻiʻo a hoʻonui me ka nui o ka palaoa o ka tungsten carbide phase i loko o ka alloy tke emi nei ka ikaika compressive o WC-Co alloy. No laila, ʻoi aku ka ikaika o ka compressive ʻoi aku ka ʻoi aku ka maikaʻi o ka huila palaoa me ka cobalt haʻahaʻa.

Paʻakikī paʻakikī.

ʻO ka paʻakikī o ka hopena he helu ʻenehana koʻikoʻi o ka mining alloys, a he mea koʻikoʻi hoʻi ia no nā mea hana ʻoki intermittent ma lalo o nā kūlana paʻakikī. Hoʻonui ka paʻakikī o ka WC-Co alloy me ka hoʻonui ʻana i ka ʻike cobalt a me ka nui o ka palaoa o ka tungsten carbide. No laila, ʻo ka hapa nui o nā mea hoʻoheheʻe mining he mau mea hoʻoheheʻe coarse-grained me ka ʻike cobalt kiʻekiʻe.

Saturation magnetic. 

Tpiʻi aʻe ka ikaika induction magnetic o ka alloy me ka hoʻonui ʻana o ke kahua magnetic waho. ke piʻi ka ikaika o ke kahua magnetic i kekahi waiwai, ʻaʻole e piʻi hou ka ikaika induction magnetic, ʻo ia hoʻi, ua hōʻea ka alloy i ka saturation magnetic. ʻO ka waiwai saturation magnetic o ka huila pili wale nō i ka ʻike cobalt i loko o ka alloy. No laila, hiki ke hoʻohana ʻia ka saturation magnetic no ka nānā ʻana i ke ʻano hoʻopōʻino ʻole o ka huila a i ʻole e ʻike inā aia kahi ʻāpana η l non-magnetic i loko o ka hui me ka haku mele ʻike ʻia.

Modulus elastic.

No ka meaWCloaʻa i kahi modulus elastic kiʻekiʻe,pelaWC-Co. Ke emi nei ka modulus elastic me ka hoʻonui ʻana i ka ʻike cobalt i loko o ka alloy, a ʻo ka nui o ka palaoa o ka tungsten carbide i loko o ka alloy ʻaʻohe hopena maopopo i ka modulus elastic.With ka pii ana o ka wela lawelawe te emi ana ka modulus elastic o ka huila.

Koefisi hoonui wela.

Hoʻonui ʻia ka coefficient hoʻonui laina o WC-Co alloy me ka piʻi ʻana o ka ʻike cobalt. Eia naʻe, ʻoi aku ka haʻahaʻa o ka coefficient hoʻonui o ka mea hao ma mua o ke kila, kahi e hoʻonui ai i ke kaomi kuʻi ʻana i ka wā i hoʻokomo ʻia ai ka mea hana hao. Inā ʻaʻole lawe ʻia nā hana hoʻomaha mālie, e haki pinepine ka huila.

ʻO nā mea āpau, ʻo Tungsten carbide ka hana kiʻekiʻe i kāna mau waiwai kino. ʻO ke kumu, ʻo TʻAʻole i kaupalena ʻia nā waiwai kino pili o ka carbide cementedpoe. Ua ʻōlelo ʻo Tʻokoʻa nā hiʻohiʻona o nā mea me nā ʻano hana like ʻole no nā hoʻohana kikoʻī. Makemake ʻoe e ʻike hou aku e pili ana i ka tungsten carbide hoʻokipa e hahai iā mākou.
