He aha nā koʻokoʻo tungsten carbide composite?

Hana ʻia ke koʻokoʻo tungsten carbide composite me nā ʻōlelo aʻoaʻo carbide cemented a me ka hui Ni / Ag (Cu). ʻO nā ʻōlelo aʻoaʻo carbide mau ʻia ʻo tungsten carbide i ʻokiʻoki ʻia, nā mea hoʻokomo carbide, e like me ka hoʻokomo ʻana i ka hōkū carbide, nā mea hoʻokomo ʻano pyramid carbide, nā hoʻokomo ʻano manō, a pēlā aku. I kekahi manawa, hiki i nā ʻōlelo carbide ke tungsten carbide pauka. ʻO ka koho waiwai ʻo tungsten carbide crushed grits. Inā makemake ʻoe i ʻoi aku ka lōʻihi ma mua o ka carbide grits, ʻoi aku ka maikaʻi o ka hoʻokomo carbide. Eia nō naʻe, ʻo ka carbide cemented/crushed carbide me kahi ʻoi ʻoi aku ka maikaʻi o ka pale ʻana a me ka hiki ke ʻoki.

ʻO 89-91 HRA ka paʻakikī, ʻo ka mea hoʻopaʻa paʻa ʻo Ni a me ke keleawe keleawe, hiki i ka ikaika ke piʻi i 690MPa, paʻakikī HB≥160.

No ka pōkole, ʻo ka hapa nui o nā koʻokoʻo Composite i hana ʻia me ka hoʻohana ʻia ʻana o nā kīʻaha Tungsten Carbide sintered i hoʻopaʻa ʻia me ka matrix nickel keleawe, (Cu 50 Zn 40 Ni 10) me kahi wahi hoʻoheheʻe haʻahaʻa (870°C).

No ke aha e hoʻohana ai i ka tungsten carbide grits i mea nui

Ua ʻike mākou a pau he paʻakikī kiʻekiʻe ka tungsten carbide,He hana maikaʻi ʻo Tungsten carbide i ka ʻoki kila.TLoaʻa i nā kumu kūʻai kūʻē ʻo ungsten carbide grits. Ua ʻōlelo ʻo THiki i ka ungsten carbide grits ke pale i ka ʻili o nā mea hana i pili i ka ʻaʻahu abrasive. Ua ʻōlelo ʻo Tnā ʻōlelo aʻoaʻo karbida ungsten raiseka wikiwiki o ka wili ʻana a me ka ʻoki ʻana，ka mālama ʻana i ke ana piha ma nā stabilizers, alakaʻi i nā wipers noho kī, a me nā mea hana ʻē aʻe.

ʻO ka nui o ka palaoa o ka carbide grits:

1/8-1/16 in. ( 3.2-1.6 mm )

3/16-1/8 iniha (4.8-3.2 mm)

1/4-3/16 iniha (6.3-4.8 mm)

3/8-5/16 iniha (9.5-7.9 mm)

5/16-1/4 iniha (7.9 -6.3 mm)

3/8-1/4 iniha (9.5-6.3 mm)

1/2-5/16 iniha (12.7-7.9 mm)

ʻO nā māka o nā lāʻau hui

ʻElua mau papa nui e pili ana i nā ʻano like ʻole o ka tungsten carbide grits

1. Papa ʻoki:70% tungsten carbide + 30% binder

2. Wear grade:60% tungsten carbide + 40% binder

Hiki iā ʻoe ke koho i nā māka like ʻole ma muli o kāu noi.

Makemake ʻoe e ʻike hou aku e pili ana i nā koʻokoʻo tungsten carbide composite a me nā mea paʻakikī ʻē aʻe? leka uila iā mākou [email protected].
