Mechanical a me ke kino o ka Tungsten Carbide

ʻO ka tungsten carbide kahi huila i loaʻa ka mea nui o nā pauka me ka tungsten carbide, titanium carbide, a me ka pauka metala e like me ka cobalt, nickel, etc. Hoʻohana nui ʻia ia e hana i nā mea hana ʻoki kiʻekiʻe a me nā mea ʻoki ʻoki paʻakikī, a me nā ʻāpana lole kiʻekiʻe no ka hana ʻana i nā make anu, a me nā mea ana.

Mechanical a me ke kino waiwai o tungsten carbide

1. ʻO ka paʻakikī kiʻekiʻe a me ke kū'ēʻana

ʻO ka maʻamau, ma waena o HRA86 ~ 93, emi iho me ka piʻi ʻana o ka cobalt. ʻO ka pale ʻana o ka tungsten carbide ka mea nui loa. Ma nā hoʻohana pono, ʻo 20-100 mau manawa ka lōʻihi o ka carbide ma mua o kekahi mau mea kila kila.

2. Kiʻekiʻe anti-bending ikaika.

ʻO ka carbide sintered he modulus elastic kiʻekiʻe a loaʻa ka piko liʻiliʻi loa i ka wā e hoʻokau ʻia ai ka ikaika wili. ʻO ka ikaika kulou i ka mahana maʻamau ma waena o 90 a me 150 MPa a ʻoi aku ka kiʻekiʻe o ka cobalt, ʻoi aku ka kiʻekiʻe o ka ikaika anti-bending.

3. Ke kū'ē i ka corrosion

Hoʻohana maʻamau ia i nā kaiapuni kemika a me ka corrosive no ka mea ʻaʻole inert kemika nā carbide. ʻOi aku ka paʻa o nā waiwai kemika. Loaʻa i ka mea Carbide ke kūpaʻa waika, kūʻē i ka alkali, a me ka oxidation koʻikoʻi a hiki i nā wela kiʻekiʻe.

4. Ka ikaika torsional

ʻO ka nui o ka torsion he ʻelua manawa o ke kila kiʻekiʻe a me ka carbide ka mea i makemake ʻia no nā noi hana kiʻekiʻe.

5. Ka ikaika compressive

ʻO kekahi mau māka o ka cobalt carbide a me ka cobalt he hana maikaʻi loa ma lalo o ke kaomi kiʻekiʻe kiʻekiʻe a lanakila loa i nā noi kaomi a hiki i ka 7 miliona kPa.

6. Oolea

Loaʻa i nā māka carbide sima me nā mea hoʻopili kiʻekiʻe i ka hopena maikaʻi loa.

7. Haʻahaʻa wela komo pale

ʻOiai ma kahi mahana haʻahaʻa loa, maikaʻi mau ka carbide e ʻaʻahu i ke kūpaʻa a hāʻawi i nā coefficient friction haʻahaʻa me ka hoʻohana ʻole ʻana i kahi lubricant.

8. Thermohardening

ʻAʻole loli ka mahana o 500 ° C a aia nō ka paʻakikī kiʻekiʻe ma 1000 ° C.

9. Kiʻekiʻe thermal conductivity.

ʻOi aku ka nui o ka conductivity thermal i ka carbide cemented ma mua o kēlā kila kiʻekiʻe, e hoʻonui ʻia me ka hoʻonui ʻana o ka cobalt.

10. He liʻiliʻi ka coefficient o ka hoʻonui wela.

He haʻahaʻa ia ma mua o ke kila kiʻekiʻe, ke kila kalapona, a me ke keleawe, a piʻi aʻe me ka piʻi ʻana o ka cobalt.
