Hua'ōlelo e pili ana i ka Tungsten Carbide

Me ka hoʻomohala ʻana o ka ʻenehana, ke ʻimi nei nā kānaka i nā mea hana ʻoi aku ka maikaʻi, a me nā mea hana no kā lākou kūkulu ʻana a me kā lākou ʻoihana. Ma lalo o kēia lewa, he kuleana koʻikoʻi ka tungsten carbide i ka ʻoihana hou. A ma kēia ʻatikala, e hoʻolauna ʻia kekahi mau huaʻōlelo e pili ana i ka tungsten carbide.

1. ʻO ka carbide sima

ʻO ka carbide i hoʻopaʻa ʻia e pili ana i kahi hui sintered i haku ʻia me nā carbide metala refractory a me nā mea hoʻopaʻa metala. Ma waena o nā carbide metala, tungsten carbide, titanium carbide, tantalum carbide, a pēlā aku nā carbide i hoʻohana mau ʻia i kēia manawa. A ʻo ka mea hoʻopaʻa metala i hoʻohana nui ʻia ʻo ia ka pauka cobalt, a ʻo nā mea hoʻopaʻa metala ʻē aʻe e like me nickel, a me ka hao, e hoʻohana ʻia i kekahi manawa.

2. Tungsten carbide

ʻO Tungsten carbide kahi ʻano carbide cemented, i hui pū ʻia me ka pauka tungsten carbide a me nā mea hoʻopaʻa metala. Me ka helu hoʻoheheʻe kiʻekiʻe, ʻaʻole hiki ke hana ʻia nā huahana tungsten carbide e like me nā mea ʻē aʻe. ʻO ka powder metallurgy kahi ala maʻamau no ka hana ʻana i nā huahana tungsten carbide. Me nā tungsten atoms a me nā kalapona kalapona, nā huahana tungsten carbide he nui nā waiwai maikaʻi, e hoʻolilo iā lākou i mea mea hana kaulana i ka ʻoihana hou.

3. ʻO ka mānoanoa

ʻO ka Density e pili ana i ka ratio o ka nuipaʻa i ka nui o ka mea. Loaʻa i kona nui ka nui o nā pores i loko o ka mea.

I nā huahana tungsten carbide, cobalt a i ʻole nā ​​​​mea metala ʻē aʻe. ʻO ka tungsten carbide grade YG8 maʻamau, nona ka 8% cobalt, he 14.8g/cm3. No laila, i ka piʻi ʻana o ka ʻike cobalt i loko o ka tungsten-cobalt alloy, e emi ka nui o ka nui.

4. Oolea

ʻO ka paʻakikī e pili ana i ka hiki i kahi mea ke pale aku i ka hoʻololi ʻana o ka plastic. Hoʻohana pinepine ʻia ʻo Vickers hardness a me Rockwell hardness no ke ana ʻana i ka paʻakikī o nā huahana tungsten carbide.

Hoʻohana nui ʻia ka paʻakikī Vickers ma ka honua. ʻO kēia ʻano ana paʻakikī e pili ana i ka waiwai paʻakikī i loaʻa ma ke ana ʻana i ka nui o ka indentation me ka hoʻohana ʻana i kahi daimana e komo i ka ʻili o ka hāpana ma lalo o kekahi kūlana haʻahaʻa.

ʻO ka paʻakikī ʻo Rockwell kekahi ʻano o ke ana paʻakikī i hoʻohana mau ʻia. Ana ia i ka paʻakikī me ka hoʻohana ʻana i ka hohonu komo o kahi cone daimana maʻamau.

Hiki ke hoʻohana ʻia ke ʻano ana paʻakikī ʻo Vickers a me ke ʻano ana paʻakikī ʻo Rockwell no ke ana ʻana i ka paʻakikī o ka carbide cemented, a hiki ke hoʻololi ʻia nā mea ʻelua.

ʻO ka paʻakikī o ka carbide tungsten mai 85 HRA a 90 HRA. ʻO ka papa maʻamau o ka tungsten carbide, YG8, he paʻakikī o 89.5 HRA. Hiki i kahi huahana tungsten carbide me ka paʻakikī kiʻekiʻe ke hoʻomanawanui i ka hopena a ʻoi aku ka maikaʻi o ka lole, no laila hiki ke hana lōʻihi. Ma ke ʻano he bonder, ʻoi aku ka liʻiliʻi o ka cobalt i ka ʻoi aku ka paʻakikī. A hiki i ke kalapona haʻahaʻa ke hoʻoikaika i ka tungsten carbide. Akā hiki i ka decarbonization ke hana maʻalahi i ka tungsten carbide e hōʻino. ʻO ka maʻamau, e hoʻonui ka tungsten carbide i kona paʻakikī.

5. Kulou ikaika

Hoʻonui ʻia ka hāpana ma ke ʻano he kaola i kākoʻo wale ʻia ma nā fulcrums ʻelua, a hoʻopili ʻia kahi haʻawe i ka laina waena o nā fulcrums ʻelua a hiki i ka haki ʻana o ka hāpana. Hoʻohana ʻia ka waiwai i helu ʻia e ke ʻano wili e like me ka ukana i koi ʻia no ka haʻihaʻi a me ka ʻāpana cross-sectional o ka hāpana. ʻIke ʻia hoʻi ʻo ka transverse rupture strength or bending resistance.

I ka WC-Co tungsten carbide, piʻi ka ikaika flexural me ka hoʻonui ʻana o ka ʻike cobalt o ka tungsten-cobalt alloy, akā i ka wā e hiki ai ka ʻike cobalt ma kahi o 15%, hiki i ka ikaika flexural i ka waiwai kiʻekiʻe, a laila hoʻomaka i ka iho.

Ana 'ia ka ikaika pi'o e ka awelika o kekahi mau waiwai ana. E loli ana kēia waiwai ma muli o ka hoʻololi ʻana o ka geometry o ka specimen, ke ʻano o ka ʻili, ke koʻikoʻi o loko, a me nā hemahema o loko o ka mea. No laila, ʻo ka ikaika flexural kahi ana o ka ikaika wale nō, a ʻaʻole hiki ke hoʻohana ʻia ka waiwai flexural ikaikai kumu no ke koho mea.

6. Ka ikaika o ka uhaki ʻana

ʻO ka ikaika rupture transverse ka hiki o ka tungsten carbide e pale aku i ke kulou. ʻOi aku ka paʻakikī o ka hoʻopōʻino ʻana ma lalo o ka hopena ʻo Tungsten carbide me ka ʻoi aku ka maikaʻi o ka rupture transverse ikaika. ʻOi aku ka maikaʻi o ka ʻoki ʻana o ka tungsten carbide. A i ka wā e puʻunaue like ai nā ʻāpana o ka tungsten carbide, ʻoi aku ka maikaʻi o ka transverse, a ʻaʻole maʻalahi ka pōʻino o ka tungsten carbide. ʻO ka ikaika rupture transverse o nā huahana tungsten carbide YG8 ma kahi o 2200 MPa.

7. Ka ikaika hooikaika

ʻO ka ikaika koʻikoʻi ke koena o ka mana magnetic i ana ʻia ma ka hoʻopaneʻe ʻana i kahi mea magnetic i loko o kahi carbide i hoʻopaʻa ʻia i kahi mokuʻāina piha a laila demagnetizing ia.

Aia ka pilina pololei ma waena o ka nui o ka nui o ka nui o ka māhele carbide cemented a me ka ikaika koi. ʻOi aku ka maikaʻi o ka nui o ka nui o ka ʻāpana magnetized, ʻoi aku ka kiʻekiʻe o ka waiwai hoʻoikaika. I loko o ka lab, ua hoʻāʻo ʻia ka ikaika coercive e kahi mea hoʻāʻo ikaika coercive.

ʻO kēia nā huaʻōlelo o ka tungsten carbide a me kāna mau waiwai. E hōʻike ʻia nā huaʻōlelo ʻē aʻe ma nā ʻatikala aʻe.

Inā makemake ʻoe i nā huahana tungsten carbide a makemake ʻoe i ka ʻike hou aʻe a me nā kikoʻī, hiki iā ʻoe ke CONTACT US ma ke kelepona a i ʻole leka uila ma ka hema, a i ʻole SEND US MAIL ma lalo o ka ʻaoʻao.
