ʻO ka hoʻohui ʻana o nā mea hana paahana

Hana ʻia nā mea hana paʻa me ka carbide (i kapa ʻia ʻo ka pae paʻakikī) a me ka metala (i kapa ʻia ʻo binder phase) me ka paʻakikī kiʻekiʻe a me ka helu heheʻe ma o ka pauka metallurgy.Ma kahi o nā mea paahana carbide i hoʻohana mau ʻia he WC, TiC, TaC, NbC, etc., ʻo nā mea hoʻopili maʻamau ʻo Co, titanium carbide-based binder ʻo Mo, Ni.

ʻO nā waiwai kino a me nā mīkini o nā mea hana paʻa e pili ana i ka hoʻohui ʻana o ka mea hoʻohui, ka mānoanoa o nā ʻāpana pauka a me ke kaʻina sintering o ka alloy.ʻOi aku ka paʻakikī paʻakikī me ka paʻakikī kiʻekiʻe a me ka helu heheʻe kiʻekiʻe, ʻoi aku ka kiʻekiʻe o ka paʻakikī a me ke kiʻekiʻe o ka wela wela o ka mea hana alloy ʻO ka mea paʻa, ʻoi aku ka ikaika.ʻO ka hoʻohui ʻana o TaC a me NbC i ka huila he mea maikaʻi ia e hoʻomaʻemaʻe i nā kīʻaha a hoʻomaikaʻi i ke kūpaʻa wela o ka pā.ʻO ka carbide cemented maʻamau i loaʻa ka nui o WC a me TiC, no laila ʻo ka paʻakikī, ʻaʻahu i ke kūpaʻa a me ke kūʻē ʻana ʻO ke kūpaʻa wela ʻoi aku ka kiʻekiʻe ma mua o ke kila kila, ʻo ka paʻakikī i ka lumi wela ʻo 89 ~ 94HRA, a ʻo ke kūpaʻa wela he 80 ~ 1000 degere.
