Nā pōmaikaʻi, nā pōʻino, a me nā ʻokoʻa ma waena o ke kila kiʻekiʻe a me ka carbide cemented

1. Kiekie-wikiwiki kila:

ʻO ke kila kiʻekiʻe ke kalapona kiʻekiʻe a me ke kila kila kiʻekiʻe. Wahi a ka haku mele, hiki ke hoʻokaʻawale ʻia i ka tungsten series a me ka molybdenum series steel, a e like me ka ʻoki ʻana i ka hana, hiki ke hoʻokaʻawale ʻia i ke kila kiʻekiʻe kiʻekiʻe a me ke kila kiʻekiʻe kiʻekiʻe. Pono e hoʻoikaika ʻia ke kila kiʻekiʻe e ka mālama wela. I ka moku'āina pio, ka hao, chromium, hapa o ka tungsten, a me ka kalapona i loko o ke kila kiʻekiʻe-wikiwiki carbide paʻakikī loa, i hiki ke hoʻoikaika i ke kapa komo o ke kila (paʻakikī hiki i HRC64-68).

Hoʻoheheʻe ʻia ka ʻāpana ʻē aʻe o ka tungsten i loko o ka matrix a hoʻonui i ka ʻulaʻula paʻakikī o ke kila. Hiki i ka ʻulaʻula ʻulaʻula o ke kila kiʻekiʻe ke hiki i 650 degere. ʻO ke kila kiʻekiʻe ka ikaika a me ka paʻakikī. Ma hope o ka hoʻokala ʻana, ʻoi ka ʻoki ʻoki a paʻa ka maikaʻi. Hoʻohana maʻamau ia e hana i nā mea hana liʻiliʻi a paʻakikī.

2. carbide sima:

ʻO ka carbide Cemented he micron-order refractory high-hardness metal carbide pauka, i hana ʻia ma ke kī ʻana i ka wela kiʻekiʻe a me ke kaomi kiʻekiʻe me ka cobalt, molybdenum, nickel, etc. ʻOi aku ka nui o nā carbide wela kiʻekiʻe i ka carbide cemented ma mua o ke kila kiʻekiʻe, me ka paʻakikī kiʻekiʻe (HRC75-94) a me ke kūpaʻa maikaʻi.

Hiki ke hiki i ka 800-1000 degere ka paʻakikī paʻakikī. ʻO ka wikiwiki o ka ʻoki ʻana o ka carbide cemented he 4-7 mau manawa kiʻekiʻe ma mua o ke kila kiʻekiʻe. ʻOkiʻoki kiʻekiʻe.

He kiʻekiʻe ka paʻakikī o ka carbide, ka ikaika, ka ʻaʻahu-kū'ē, a me ke kū'ē corrosion, a ua ʻike ʻia ʻo ia ʻo "nā niho ʻoihana". Hoʻohana ʻia ia no ka hana ʻana i nā mea hana ʻoki, nā pahi, nā mea hana cobalt, a me nā ʻāpana kūʻokoʻa, a hoʻohana nui ʻia i ka pūʻali koa, aerospace a me ka mokulele, Mechanical processing, metallurgy, oil drilling, mining tools, electronic communications, construction, and other fields. me ka hoʻomohala ʻana o nā ʻoihana i lalo, ke hoʻomau nei ka piʻi ʻana o ka mākeke no ka carbide cemented. A i ka wā e hiki mai ana, ʻo ka hana ʻana i nā mea kaua kiʻekiʻe-ʻenehana a me nā mea hana, ka holomua ʻana o ka ʻepekema a me ka ʻenehana, a me ka hoʻomohala wikiwiki ʻana o ka ikehu nuklea e hoʻonui nui i ka noi no ka ʻenehana kiʻekiʻe kiʻekiʻe, a me nā huahana carbide cemented paʻa. .
