Ua make ke kaha kii uea karbida Tungsten

ʻO ka make kiʻi uea ka mea nui o ka ʻoihana kiʻi uea. A no ka hana ʻana i ka uea kiʻekiʻe ma ke kumu kūʻai haʻahaʻa a me nā tona o ka uea, pono ke kiʻekiʻe o ke kiʻi kiʻi uea. ʻO ke koho kūpono ʻole a me ka maikaʻi maikaʻi ʻole o ka make e hoʻohui ʻia ʻaʻole wale i ke kumu kūʻai make akā e hana pū nō hoʻi i ka uea me ka maikaʻi ʻole o ka ʻili, ka haʻahaʻa haʻahaʻa, a me nā waiwai metallurgical maikaʻi ʻole a me ka manawa lōʻihi o ka mīkini, a me ka nalowale o ka hana. No laila, ua ʻōlelo ʻia ʻo ka hana uea a me ka hana make he hui mau no ka maikaʻi. E kamaʻilio wale kēia ʻatikala e pili ana i ke koʻikoʻi o ke kaha kiʻi uea tungsten carbide make.

Nui nā mea i loaʻa no ka hana ʻana i nā make kiʻi uea, me ka tungsten carbide, ke daimana maoli, ke daimana synthetic, PCD, a pēlā aku. Loaʻa i kēlā me kēia o lākou ka laulā o nā noi. Aneane a pau uea paha piha a ma ka liʻiliʻi loa hapa, mai ka uea koʻokoʻo i kekahi nui ma muli o ka mea a me ka makemake pololei, e tungsten carbide make ma muli o ko lakou kino waiwai a me ka pono kumu kuai.

ʻO ka make ʻana o Tungsten carbide he paʻakikī kiʻekiʻe ma ka lumi wela a me nā wela kiʻekiʻe i loaʻa i nā hana kaha kiʻi. E like me ka tungsten carbide nibs i hana ʻia e ke ʻano metallurgy pauka a hana ʻia me ka tungsten carbide. Hiki ke hana ʻia nā nibs tungsten carbide i nā māka like ʻole. ʻOkoʻa nā māka o tungsten carbide uea kaha kiʻi make ʻokoʻa ka paʻakikī, mai 1400 a 2000 HV.

Ua make ʻo Tungsten carbide i ke kūpaʻa kiʻekiʻe e kūʻē i ka deformation ma lalo o ka ukana a loaʻa kahi koena wela liʻiliʻi o ka hoʻonui. ʻO ka hopena, he liʻiliʻi ka hoʻololi ʻana i ka nui o nā mea make ma muli o ka piʻi ʻana o nā mahana hana. ʻOiai ʻoi aku ka maikaʻi o ka hana kiʻi kiʻi uea PCD ma mua o ka make ʻana o ke kaha kiʻi uea tungsten carbide, ʻoi aku ka maikaʻi o ka make ʻana o ke kiʻi uea tungsten carbide.

No ke kaha kiʻi uea, pono nā nibs e ʻaʻahu i ke kūpaʻa a paʻakikī e pale i ka deformation ma lalo o ka ukana. No ka mea, ʻo ka paʻakikī a me ka paʻakikī o kēlā me kēia mea he mea like ʻole, pono kahi hui maikaʻi loa o nā waiwai ʻelua e like me ka noi. ʻO ka mea hou aku, hiki i ka 1700 a i ka 2800 N / mm2 ka ikaika o ke kaha kaha o ka tungsten carbide uea kiʻi, i hana ʻia no ke kaha kiʻi. Loaʻa nā māka like ʻole ma ka hoʻololi ʻana i ka nui o ka palaoa o ka tungsten carbide a me ka pākēneka cobalt.

I ka hōʻuluʻulu ʻana, hiki ke hana ʻia nā make kiʻi uea i nā mea like ʻole, akā naʻe, ʻo ka mea kaulana loa ʻo tungsten carbide uea kiʻi make, no ka mea, he kūpono ke kumukūʻai a he hana nui.
