Pehea ka nui o kāu ʻike e pili ana i nā ʻāpana tungsten carbide?

ʻAʻole pilikia inā ua hoʻohana ʻoe i nā ʻāpana tungsten carbide a i ʻole, akā manaʻo wau ua ʻike paha ʻoe i kekahi mea e pili ana i ka tungsten carbide. Hiki iā mākou ke ʻike pinepine i nā huahana tungsten carbide i ko mākou ola. No ka laʻana, ke lawe mākou i ke kaʻa, ʻike mākou i ka hāmare ma ka puka makani kaʻa, ʻo ia ka mea a mākou e hoʻohana ai e wāwahi i ka puka makani e pakele ai ke hālāwai mākou i kahi pilikia. ʻO ka mea maʻamau, e hana ʻia kēia ʻano hāmare me ka tungsten carbide, no kona paʻakikī kiʻekiʻe. Inā maʻa ʻoe i ka ʻaʻahu ʻana i ka wati, aia kekahi mea paʻa paʻa i ka wati ma muli o kona kūpaʻa kiʻekiʻe.

ʻO ka paʻakikī o ka carbide cemented ka lua wale nō i ka daimana he kiʻekiʻe loa ke pale ʻana i ka lole. Maopopo iā ʻoe ke kumu o ka paʻakikī o ka carbide sima?

No ka mea ʻo tungsten carbide kahi huahana metallurgical sintered o ka pauka. Hana ʻia ia i loko o ka umu a i ʻole Hydrogen reduction furnace me ka refractory Tungsten material (WC) micron pauka e like me ka mea nui a me Cobalt (Co), Nickel (Ni), a i ʻole Molybdenum (Mo) e like me ka mea hoʻopili.

ʻAʻole wale ka tungsten carbide i nā hiʻohiʻona o ka paʻakikī kiʻekiʻe a me ke kūpaʻa ʻaʻahu kiʻekiʻe akā ʻo ke kūpaʻa corrosion a me ka paʻa paʻa ma lalo o ke kiʻekiʻe kiʻekiʻe (ʻoiai ma 500 ºC ʻaʻole i loli a ma 1000 ºC mau nō ka paʻakikī)
Loaʻa i nā ʻāpana tungsten carbide nā ʻano āpau o ka tungsten carbide.





E hana i ka hana o nā ʻāpana tungsten carbide
ʻO nā ʻāpana carbide e pili ana i ka rectangular,ʻike pū ʻia ʻo tungsten carbide flats. Hana ʻia ia ma o ka pauka (Mainly WC a me Co pauda e like me ka formula) ka hui ʻana, ka wili pōleʻa, ka hoʻomaloʻo ʻana i ka hale kiaʻi, extruding, hoʻomaloʻo, sintering, (a ʻokiʻoki a wili paha inā pono) ka nānā hope ʻana, hoʻopili a lailaka lawe ʻana, hana ʻia ka nānā waena ma hope o kēlā me kēia kaʻina hana e hōʻoia i nā huahana kūpono wale nō ke neʻe ʻia i ke kaʻina hana aʻe.

Ka mana maikaʻi o nā ʻāpana tungsten carbide
ʻO ka HRA tester, TRS tester, Metallographic microscope (Check microstructure), coercive force tester, cobalt magnetic tester e hoʻohana ʻia e nānā a hōʻoia i ke kūpono o ka mea o ka carbide strip, ʻokoʻa, hoʻohui ʻia ka hoʻāʻo hāʻule i ka nānā ʻana i ka carbide strip e hōʻoia ʻaʻohe hemahema o ke kaula lōʻihi. A ʻo ka nānā ʻana i ka nui e like me ke kauoha.

Ka hoʻohana ʻana i nā ʻāpana tungsten carbide
ʻAʻole kūlike nā ʻike o WC a me Co i loko o nā ʻāpana tungsten carbide me nā hoʻohana ʻokoʻa, a ākea ka laulā noi. ʻIke nui ʻia ʻo Tungsten carbide strip ma ke ʻano he ʻano mea ʻoki carbide. ʻO wai ka mea kūpono no ka mālama ʻana i ka lāʻau paʻa, ka papa kahi, a me ka papa fiber-density? Hiki ke hoʻohana ʻia nā ʻāpana carbide sima no ka hana ʻana i nā mea hana lāʻau, e like me ka hana ʻana i nā mea hana, reamer, nā ʻili pahi serrated, a me nā ʻāpana like ʻole.

E koho i ka papa
Piʻi ka paʻakikī i ka emi ʻana o ka cobalt a me ka
e emi ana ke anawaena o ka tungsten carbide. Piʻi ka ikaika flexural e like me
piʻi ka cobalt a emi ke anawaena o ka tungsten carbide.
No laila, he hana koʻikoʻi loa ia e koho i ka papa kūpono loa e like me
nā hoʻohana like ʻole, nā mea ʻokoʻa i hana ʻia, a me nā wahi hana like ʻole.
ʻO ke koho kūpono ʻole o nā māka e hoʻopilikia i nā pilikia e like me ka ʻoki ʻana, ka haʻihaʻi, ka ʻaʻahu maʻalahi,
a pōkole ke ola.

Nui nā māka e koho ai

Pehea e koho koke ai i ka papa kūpono?
Inā ʻaʻole ʻoe maopopo i ka papa hea kāu huahana e kūpono ai, Welina maikāhea iā mā ˚ ou.
