Ma ka noiʻi a me ka hoʻomohala ʻana i nā huahana carbide cemented, lawe pinepine mākou i ka "mālama ʻana i nā waiwai ʻē aʻe o ka carbide cemented a me ka hoʻomaikaʻi ʻana i kona paʻakikī e like me ka hiki" ma ke ʻano he pahuhopu noiʻi, i mea e loaʻa ai ka hana ʻoi aku ka maikaʻi.

E like me nā mea metala, hiki ke hōʻike ʻia ka paʻakikī o ka carbide cemented ma ke ʻano o ka paʻakikī o ka hopena a me ka paʻakikī haʻihaʻi. Aia kahi pilina laina ma waena o ka paʻakikī hopena a me ka ikaika flexural o ka carbide cemented. ʻO nā mea e hoʻoholo ai i ka ikaika flexural o ka alloy e hoʻopili ikaika i ka hopena o ka paʻakikī. Hoʻopili pū ʻia ka paʻakikī o ka paʻakikī e nā kumu ʻē aʻe.

ʻO ka paʻakikī paʻakikī ka hiki i kahi mea ke pale aku i ka hemahema ma lalo o ka hoʻouka ʻana. Loaʻa i nā hemahema o loko i loko o nā alloys nā hopena like i ka ikaika flexural a me ka paʻakikī hopena. Ma keʻano laulā, he mau mea palupalu nā mea paʻa paʻa, a ʻo ka hana elastic deformation ka helu nui i ka wā e hoʻopili ʻia ai ka hopena, no laila he mana koʻikoʻi ka ikaika flexural o ka alloy i ka waiwai o ka paʻakikī hopena.

No ka huila i loaʻa iā 10% Co, me ka hoʻonui ʻana i ka nui o ka palaoa WC, ʻoiai ke piʻi aʻe ka paʻakikī o ka haʻihaʻi ʻana, e emi ana ka ikaika flexural a me ka emi ʻana o ka waiwai o ka paʻakikī, e hōʻike ana he alakaʻi nui ka ikaika flexural i ka paʻakikī hopena. .

Ke piʻi aʻe ka paʻakikī o ka carbide cemented, e emi ana ka paʻakikī o ka haki. Akā, i loko o kahi kikoʻī, hōʻike ia e pili ana nā mea ʻē aʻe i ka paʻakikī haʻihaʻi ma lalo o ka paʻakikī like.

Ma ka nānā ʻana i ka pilina ma waena o ka paʻakikī o ka hopena, ka paʻakikī o ka haʻihaʻi a me nā ʻano mīkini ʻē aʻe a me nā ʻāpana kūkulu o ka carbide cemented i hana ʻia e nā haku like ʻole, ka nui o ka WC a me nā kūlana kaʻina like ʻole, e huki mākou i kēia mau hopena:

Nui nā kumu e pili ana i ka waiwai paʻakikī o ka carbide cemented, me ka nui o nā hemahema o ke kūkulu ʻana, ka ikaika a me ka paʻakikī, a me nā mea ʻē aʻe. ʻO ka ikaika flexural o ka'āpana he mea nui ka hopena i ka hopena o ka paʻakikī. Ma lalo wale nō o ke ʻano o ka ikaika flexural like, ʻoi aku ka maikaʻi o ka ʻoi aku o ka ʻoi aku ka maikaʻi o nā ʻāpana me ka paʻakikī haʻi maikaʻi.

ʻO ka paʻakikī o ka haʻihaʻi o ka carbide cemented e pili nui i ka paʻakikī. Ke piʻi aʻe ka paʻakikī o ka huila, e emi ana ka paʻakikī o ka haʻihaʻi ma ka laina laina, akā e loli ana i loko o kahi ākea. Ke ʻano like ka paʻakikī, ʻoi aku ka maikaʻi o ka haʻihaʻi ʻana o ka haʻahaʻa Coarse-grained alloy. ʻOi aku ka ikaika o ka haʻihaʻi ʻoi aku ka ikaika o ka flexural a me ka paʻakikī o ka hopena ma mua o nā ʻāpana like ʻole.

Hoʻohālikelike ʻia me ka waiwai paʻakikī o ka carbide cemented, ʻoi aku ka nui o ka waiwai o ka paʻakikī haʻi. Hoʻohui pū ʻia me nā hōʻailona hana mechanical ʻekolu o ka paʻakikī haʻihaʻi, paʻakikī a me ka ikaika flexural o ka alloy, Hiki iā ia ke hōʻike maikaʻi i ka hana o ka alloy.
