Hana ʻia ka tungsten carbide strip i ka WC tungsten carbide a me ka Co cobalt pauka i hui ʻia e ke ʻano metallurgical e ka pulverization, ka milling ball, ke kaomi ʻana a me ka sintering, ʻo nā ʻāpana alloy nui ʻo WC a me Co, ka ʻike o WC a me Co i nā hoʻohana like ʻole o ka tungsten carbide strip. ʻaʻole like, a ākea loa ka laulā hoʻohana.
ʻO kekahi o nā mea nui loa o nā ʻāpana tungsten carbide, ua kapa ʻia ʻo ia ma muli o kona ʻano ʻāpana ʻāpana o nā papa (a i ʻole nā ʻāpana), ʻike ʻia ʻo tungsten carbide strip/plates. ʻO ka tungsten carbide strip he paʻakikī maikaʻi loa, kūpaʻa maikaʻi i ka ʻaʻahu, modulus elastic kiʻekiʻe, ikaika compressive kiʻekiʻe, kūpaʻa kemika maikaʻi (acid, alkali, kiʻekiʻe wela oxidation resistance), haʻahaʻa haʻahaʻa haʻahaʻa, haʻahaʻa haʻahaʻa hoʻonui, thermal a me ka uila conductivity like me ka hao a me kāna. nā huila.
He aha nā kumu o kahoʻopau ʻanao na kaula tungsten carbide? E pane hou aku ʻo Chuangrui carbide:
(1) ʻAʻole i hoʻoneʻe ʻia ka ʻili o ka tungsten carbide ma mua o ke kuʻi ʻana, a ʻo ka papa o ka oxide ma ka ʻaoʻao brazing e hōʻemi ana i ka hopena o ka hoʻoheheʻe ʻana o ka metala brazing a hoʻonāwaliwali i ka ikaika paʻa o ka weld.
(2)Hoʻopau ʻiaE hana ʻia nō hoʻi ke koho ʻole ʻia a hoʻohana pono ʻia ka mea hoʻoheheʻe ʻia, no ka laʻana, ke hoʻohana ʻia ka borax ma ke ʻano he brazing agent, ʻaʻole hiki i ka borax ke hoʻokō pono i kahi hana deoxidizing no ka mea he ʻoi aku ka wai o ka borax, a ʻaʻole hiki ke pulu maikaʻi ʻia ka mea brazing. ma ka ili palapaia, a me kahoʻopau ʻanahanana hanana.
(3) ʻO ka mahana wela kūpono he 30 ~ 50 °C ma luna o ka helu hoʻoheheʻe o ka metala brazing, ahoʻopau ʻanae hana ʻia inā kiʻekiʻe a haʻahaʻa paha ka mahana. ʻO ka hoʻoulu ʻana i ka wela nui ke kumu o ka oxidation i ka weld. ʻO ka hoʻohana ʻana i ka metala brazing me ka zinc e hāʻawi i ka weld i kahi kala uliuli a keʻokeʻo paha. Ke haʻahaʻa loa ka mahana brazing, e hana ʻia kahi weld mānoanoa, a uhi ʻia ka loko o ka weld me ka porosity a me ka slag inclusions. ʻO nā kūlana ʻelua ma luna nei e hōʻemi i ka ikaika o ka weld, a maʻalahi hoʻi i ka deweld ke hoʻokala a hoʻohana ʻia.
(4) I ke kaʻina hana brazing, ʻaʻohe hoʻokuʻu slag i ka manawa a i ʻole ka lawa ʻole o ka hoʻokuʻu ʻana, no laila e mau ka nui o ka mea hoʻoheheʻe i ka weld, e hōʻemi ana i ka ikaika o ka weld a me nā kumu.hoʻopau ʻana.
