Ka hopena o ka W maʻiʻo ma ka tungsten carbide crystal bonding phase ma ka ikaika flexural o ka alloy

ʻO ka ikaika kulou he waiwai kino koʻikoʻi o ka carbide cemented.No nā'āpana kobalt kiʻekiʻe, piʻi kona ikaika me ka piʻiʻana o ka W content;ʻoiai no nā ʻāpana kobalta haʻahaʻa, he ʻoiaʻiʻo ka ʻaoʻao.

ʻO kēia no ka mea ma hope o ka manawa cobalt o kakiʻekiʻe-kobalta huilaua hoʻoikaika ʻia ka paʻa paʻa e W, ua hoʻomaikaʻi ʻia ke kūpaʻa deformation plastic o ka alloy, a laila e hoʻonui ai i ka ikaika;oiai kahaʻahaʻa-kobalta huilahe palupalu maoli, a ma hope o ka hoʻoikaika ʻia ʻana o ka ʻāpana kobalt i ka hoʻonā paʻa e W, hoʻemi ʻia ka ikaika.Ka ikaika huila.

Pono e wehewehe ʻia ka pilina ma waena o ke kūpaʻa ʻaʻahu a me ka ʻike W e ka hana o ka pae paʻa.ʻO ke kiʻekiʻe o ka W content, ʻoi aku ka ikaika o ka cobalt a ʻoi aku ka kiʻekiʻe o ke kūpaʻa ʻaʻahu;He wahi liʻiliʻi ka ʻāpana eta i ka alloy ʻaʻole e pale i ka pale ʻana i ka wā e hoʻohana ai.Eia nō naʻe, ke nui ka nui o ka ʻāpana eta, palupalu ka huila a hiki ke ʻoki a haki paha, e hōʻino ai i nā mea hana hao.
