He aha ka mea i hoʻolei ʻia ʻo Tungsten Carbide Powder

ʻO ka pauka tungsten carbide he WC a me W2C eutectic structure e hōʻike ana i kahi hiʻohiʻona hina hina. Hoʻokumu ʻia ka pauka tungsten carbide e kahi kaʻina hana kiʻekiʻe: hui pū ʻia nā pauka tungsten carbide a hoʻopaʻa ʻia i loko o kahi moku graphite. Hoʻohui pū ʻia lākou i loko o kahi umu hoʻoheheʻe ma 2900 ° C a paʻa i kekahi manawa e loaʻa ai kahi poloka hoʻolei ʻia me nā WC a me W2C eutectic phases me ka nui o ka palaoa o 1 ~ 3 μm.

Hōʻike ia i ka ʻaʻahu koʻikoʻi a me ke kūpaʻa hopena, a me ka waiwai paʻakikī kiʻekiʻe, i nā wela kiʻekiʻe. ʻO ka nui o ka tungsten carbide particle mai 0.038 mm a i 2.362 mm. Paʻakikī: 93.0 ~ 93.7 HRA; micro-paʻakikī: 2500 ~ 3000 kg / mm2; mānoanoa: 16.5 g/cm3; helu hehee: 2525°C.

Ka hana kino o ka pauka tungsten carbide

Nā hoʻohana ʻana i ka tungsten carbide grits

1. E hoʻohana i nā ʻāpana a me nā ʻāpana ili. ʻO nā ʻāpana a me nā ʻāpana e loaʻa ana ka haʻalulu, abrasion, cavitation, a me nā ʻāpana ʻāpana e like me nā mea ʻoki ʻoki, nā mea hana wili, nā mea mahiʻai, a me nā uhi paʻa.

2. Mea Hana Diamond Matrix. Hoʻohana ʻia kā mākou mākaukau-e-infiltrate a i ʻole ka wela-press cast tungsten carbide pauka e like me ka pauka matrix e paʻa a kākoʻo i ka mea hana ʻoki daimana. Hāʻawi ka mea paʻa i ka ʻike daimana maikaʻi loa e pono ai no ka hana pono o ka mea hana.

Nā ʻano hana o ka pauka tungsten carbide

1. Ke Kaʻina Hoʻopuʻi Thermal. Hiki ke hoʻoheheʻe ʻia nā kāʻei tungsten carbide e hana i nā uhi paʻa paʻa ma luna o nā ʻili e koi ana i ka hoʻonui ʻana i ke kūpaʻa aahu.

2. Hoʻokomo. Hoʻokomo ʻia ka pahu tungsten carbide, metala tungsten coarse, a i ʻole nā ​​pauka tungsten carbide me ka metala wai (e laʻa me ka hao keleawe, keleawe) e hana i ka ʻāpana. Loaʻa i kā mākou mau pauka tungsten carbide koʻikoʻi nā mana infiltration a me nā hiʻohiʻona e hiki ai i kā mākou mea kūʻai ke hana i kahi hopena hoʻokūkū no ka hoʻonui ʻana i ke ola lawelawe a me ka hoʻolālā hoʻolālā.

3. Ka pauda Metallurgical (P/M). Hoʻopili ʻia nā pauka tungsten carbide i nā ʻāpana ma o ke kaomi wela a me ka sintering.

4. Hoʻopili ʻia ʻo Plasma Transfered Arc (PTA). Ma muli o ka weldability maikaʻi loa o ka pauka tungsten carbide, hoʻohana maʻamau ia i nā mea ma o ke kaʻina hana kuʻi PTA.

5. Luʻu i nā uhi. ʻO nā uhi e like me nā mea i loaʻa i loko o nā electrodes, nā mea hana wili, a me nā ʻāpana e pili ana i ka hoʻoili ʻana i ka media abrasive ua hoʻopaʻa ʻia me ka tungsten carbide e hāʻawi ana i ka hoʻopau ʻana i ka ʻili me ka paʻakikī loa a me ke kūpaʻa.
