ʻO ke kaʻina hana o ka pihi tungsten carbide

ʻO ka mua ka hoʻomākaukau ʻana i nā mea maka. Hoʻohana pinepine ʻia ka tungsten a me ka cobalt cemented carbide e hana i ka pihi tungsten carbide, a hui pū ʻia ka tungsten carbide, cobalt a me nā pauka ʻē aʻe i kekahi ʻāpana. Pono e hoʻomaʻemaʻe maikaʻi ʻia kēia mau pauka e hōʻoia i ka nui o nā ʻāpana like ʻole a me ka maʻemaʻe kiʻekiʻe, e kau ana i ke kumu no ka hana hana ma hope.

ʻO ka mea aʻe e hiki mai ana ka pae hoʻoheheʻe pauda. Hoʻopili ʻia ka pauda hui ʻia ma lalo o ke kaomi kiʻekiʻe i ke ʻano mua o nā niho spherical ma o kahi ʻano kikoʻī. Pono kēia kaʻina hana i ka mana pololei o ke kaomi a me ka mahana e hōʻoia i ka like like a me nā ana pololei o nā niho. ʻOiai ua loaʻa ke ʻano o ke kino o ka niho spherical i kaomi ʻia, ʻano palupalu.

Hoʻopili ʻia kēia me ke kaʻina hana sintering. Hoʻopili ʻia ke kino niho spherical i loko o kahi umu hoʻoheheʻe kiʻekiʻe, a ma lalo o ka hana o ke kiʻekiʻe kiʻekiʻe, hoʻopuehu ka pauka a hui pū ʻia e hana i kahi ʻano carbide cemented ikaika. Pono e mālama pono ʻia nā ʻāpana e like me ka mahana, ka manawa a me ka lewa o ka sintering e hōʻoia i ka hana niho maikaʻi loa. Ma hope o ka sintering, ua hoʻomaikaʻi maikaʻi ʻia nā waiwai o nā niho pōpō e like me ka paʻakikī, ka ikaika a me ke kūpaʻa.

I mea e hoʻomaikaʻi hou ai i ka maikaʻi o ka ʻili a me ka pololei o nā niho pōpō, hana ʻia ka mīkini ma hope. No ka laʻana, hoʻohana ʻia ka wili, polishing a me nā kaʻina hana ʻē aʻe e hoʻomaʻamaʻa i ka ʻili o nā niho pōpō a ʻoi aku ka pololei. I ka manawa like, e like me nā koi noi like ʻole, hiki ke uhi ʻia nā niho pōpō, e like me ka titanium plating, titanium nitride plating, etc., e hoʻonui ai i kā lākou anti-wear, anti-corrosion a me nā waiwai ʻē aʻe.

Hana ʻia ka nānā ʻana i ka maikaʻi ma ke kaʻina hana. Mai ka nānā ʻana i nā mea maka, i ka hoʻāʻo ʻana i nā huahana waena i kēlā me kēia kaʻina hana, i ka hoʻokō ʻana i ka huahana hope, ʻo kēlā me kēia pae o ke ala e hōʻoia ai i ka maikaʻi o nā niho spherical e kūpono i nā kūlana kūpono. ʻO nā niho spherical wale nō i hala i nā hoʻokolohua like ʻole hiki ke hoʻokomo ʻia i ka hoʻohana pono.
