Pehea e hana ai i nā ʻōlelo aʻoaʻo Carbide

I. Ka hoomalu ana i na mea maka a me na mea kokua.

1. E ho'āʻo ʻia nā mea maka o ka pauka tungsten carbide a me ka pauka cobalt ma mua o ka hoʻohana ʻia ʻana e hana i nā mea hana tungsten carbide. E hoʻohana mākou i ka loiloi metallographic, ua hoʻoholo ʻia e loli ka nui o ka WC i loko o kahi kikoʻī, a i ka manawa like, mālama pono ʻia nā mea trace a me ka huina kalapona.

2. Ho'āʻo ʻia ka hoʻāʻo ʻana o ka wili pōleʻa no kēlā me kēia pūʻulu o WC i kūʻai ʻia, a ʻike ʻia nā ʻikepili kumu e like me ka paʻakikī, ka ikaika kulou, ka hoʻokalakupua cobalt, ka ikaika koi, a me ka mānoanoa e hoʻopaʻa pono i kona mau waiwai kino.

II. Mana kaʻina hana hana.

1. ʻO ka wili pōleʻa a me ka hui ʻana, ʻo ia ke kaʻina hana o ka granulation, ka mea e hoʻoholo ai i ka ratio loose a me ka wai o ka hui. Hoʻohana kā mākou hui i nā mea hana hou o ka spray granulation e hoʻoponopono pono i ka wai o ka hui.

2. ʻO ke kaomi ʻana, ʻo ia ke kaʻina hana o ka hoʻokumu ʻana i ka huahana, lawe mākou i kahi paʻi maʻamau a i ʻole TPA paʻi e hana ai, pēlā e hōʻemi ai i ka mana o nā kumu kanaka ma ka embryo kaomi.

3. Sintering, Hoʻohana kā mākou hui i ka ʻenehana hoʻoheheʻe haʻahaʻa haʻahaʻa e hōʻoia i ka lewa like ʻole i loko o ka umu, a me ka mana otometi o ka hoʻomehana ʻana, ka wela, ka hoʻoluʻu, a me ke koena kalapona i ke kaʻina hana sintering.

III. Hōʻike huahana.

1. ʻO ka mua, e hoʻohana mākou i ka sandblasting a i ʻole passivation o nā ʻōlelo aʻoaʻo carbide cemented e hōʻike piha i nā huahana kīnā.

2. A laila, e hoʻokō mākou i ka hoʻokolokolo metallographic o ka ʻili o ka haʻihaʻi o ka huahana, pēlā e hōʻoia ai i kahi ʻano o loko.

3. ʻO nā hoʻāʻo a me nā loiloi āpau o nā ʻāpana kino a me nā ʻenehana, me ka paʻakikī, ka ikaika, ka cobalt magnetism, ka mana magnetic, a me kekahi mau hōʻailona ʻenehana ʻē aʻe.

4. Ma hope o nā ho'āʻo a pau, e hoʻomau mākou i ka ho'āʻo welding o ka huahana e hōʻoia i ka paʻa o ka hana kuʻi.

ʻO kēia ka hana o ka hana ʻana i kēia mau ʻōlelo aʻoaʻo carbide liʻiliʻi, He paʻakikī akā pono ia.
