Nānā i nā ʻano hana hana no ka paʻa paʻa paʻa

Ua ʻike mākou a pau ʻo ka mea nui o nā alloys paʻakikī ʻo nā pauka carbide nui o ka paʻakikī kiʻekiʻe a me nā metala refractory. No laila, paʻa loa ia, a ke nīnau nei nā poʻe he nui inā he metala ka paʻa paʻa i hoʻohana ʻia no nā niho pōpō paʻa? Pehea i hiki mai ai ka hao paakiki? Ma lalo iho nei, e wehewehe aku ka mea hana ʻāpala paʻa paʻa iā ʻoe i ke ʻano hana o ka paʻa paʻa paʻa.

1. ʻO ke ʻano o ka hana ʻana o ka hao paʻa paʻa lōʻihi e like me kēia: ʻo ka mea mua, ua hana ʻia ka mea hoʻopaʻa paʻa e ka wili pōleʻa kiʻekiʻe; A laila, e like me ka lākiō kaumaha i kuhikuhi ʻia o nā ʻāpana paʻa paʻa, hoʻohui ʻia ka hui ʻana a kau ʻia i ka hoʻoikaika ʻana i ka wili pōleʻa. ʻO ka hui ʻana o ka paʻa paʻa i hana ʻia e ka wili pōleʻa a laila hoʻoheheʻe ʻia ke ʻano.

2. ʻO nā huila paʻa paʻa i hoʻohana ʻia no nā niho pōpō paʻa paʻa lōʻihi e komo pū ana me ka tungsten carbide (WC) a me ka titanium carbide (TC). ʻO nā mea paʻa paʻa ka nui o ka tungsten cobalt based (WC+Co) hard alloys (YG), tungsten titanium cobalt based (WC+TiC+Co) hard alloys (YT), tungsten tantalum cobalt based (WC+TaC+Co) hard alloys (YA), tungsten titanium tantalum cobalt based (WC+TiC+TaC+Co) alloys paakiki (WC+TiC+TaC+Co).

3. He ʻano o ka ultra-fine hard alloy pōpō niho paʻa paʻa a me kāna hana hana. ʻO ka huila he ʻāpana hui pū ʻia i ʻekolu mau mea nui: WC paʻa paʻa, Co Al ma ke ʻano metala hoʻopaʻa ʻana, a me ke ʻano metala metala laha; ʻO ka haku mele ʻana a me ke kaumaha o ka huila penei: Co Al bonding metal phase: Al13-20%, Co80-87%; hui pū ʻia: Co-AL 10-15%, Re1~3%，WC82~89%。 ʻO ke ʻano o ka hana ʻana penei: ʻo ka mua, ʻo ka mea hoʻopaʻa paʻa ʻo Co Al i lepo mai nā pōpō ikaika nui; A laila, e like me ka lākiō kaumaha i kuhikuhi ʻia o nā ʻāpana paʻa paʻa, ua hui ʻia ka hui ʻana a hoʻopaʻa ʻia i ka wili pōleʻa ikaika. ʻO ka huila paʻa paʻa i hana ʻia e ka wili pōleʻa a laila hoʻoheheʻe ʻia ma kahi mahana sintering o 1360 ℃ a me ka manawa paʻa o 20 mau minuke. Hana ʻia ka huila paʻa maikaʻi loa.
