Kusiyana pakati pa Tungsten ndi Tungsten Carbide

M'makampani amakono, zinthu za tungsten carbide zakhala chida chodziwika bwino. Ndipo tungsten sikuti imagwiritsidwa ntchito popanga babu. M'nkhaniyi, tikambirana za kusiyana kwa tungsten ndi tungsten carbide. Nkhaniyi ikufotokoza motere:

1. Kodi tungsten ndi chiyani?

2. Kodi tungsten carbide ndi chiyani?

3. Kusiyana pakati pa tungsten ndi tungsten carbide.

Kodi tungsten ndi chiyani?

Tungsten idapezeka koyamba mu 1779, ndipo idadziwika kuti "mwala wolemera" mu Swedish. Tungsten ili ndi malo osungunuka kwambiri, malo otsika kwambiri okulirapo, komanso mphamvu yotsika kwambiri ya nthunzi pakati pa zitsulo. Tungsten imakhalanso ndi elasticity yabwino komanso conductivity.

Kodi tungsten carbide ndi chiyani?

Tungsten carbide ndi aloyi wa tungsten ndi carbon. Tungsten carbide imadziwika kuti ndi yachiwiri yovuta kwambiri padziko lapansi, pambuyo pa diamondi. Kupatula kuuma, tungsten carbide ilinso ndi kukana kwabwino kovala, kukana dzimbiri, kukana kugwedezeka, komanso kulimba.

Kusiyana pakati pa tungsten ndi tungsten carbide

Tikulankhula za kusiyana pakati pa tungsten ndi tungsten carbide m'mbali zotsatirazi:

1. Elastic modulus

Tungsten ili ndi modulus yayikulu yotanuka ya 400GPa. Komabe, tungsten carbide ili ndi yokulirapo pafupifupi 690GPa. Nthawi zambiri, kuuma kwa zinthu kumagwirizana ndi elasticity modulus. Ma modulus apamwamba a elasticity ya tungsten carbide amawonetsa kuuma kwakukulu komanso kukana kusinthika.

2. Kumeta ubweya modulus

Shear modulus ndi chiŵerengero cha kumeta ubweya wa ubweya ku kukameta ubweya wa ubweya, womwe umatchedwanso modulus of rigidity. Nthawi zambiri, zitsulo zambiri zimakhala ndi shear modulus kuzungulira 80GPa, tungsten imakhala ndi kawiri, ndi tungsten carbide katatu.

3. Mphamvu zokolola zolimba

Ngakhale tungsten ndi tungsten carbide ali ndi kuuma kwabwino komanso kulimba, alibe mphamvu zokolola zambiri. Nthawi zambiri, mphamvu zokolola za tungsten zimakhala pafupifupi 350MPa, ndipo tungsten carbide ndi pafupifupi 140MPa.

4. Thermal conductivity

Thermal conductivity ndi muyeso wofunikira pamene zinthuzo zimagwiritsidwa ntchito kumalo otentha kwambiri. Tungsten imakhala ndi matenthedwe apamwamba kuposa tungsten carbide. Tungsten ili ndi kukhazikika kwa kutentha, kotero ndiyoyenera kugwiritsa ntchito matenthedwe ena, monga ma filaments, machubu, ndi ma coil otentha.

5. Kuuma

Tungsten ili ndi kuuma kwa 66, pamene tungsten carbide imakhala ndi kuuma kwa 90. Tungsten carbide imakhala ndi tungsten ndi carbon, kotero sikuti imakhala ndi zinthu zabwino za tungsten, komanso imakhala ndi kuuma ndi kukhazikika kwa mankhwala a carbon.

Ngati muli ndi chidwi ndi zinthu za tungsten carbide ndipo mukufuna zambiri ndi zambiri, mutha KULUMIKIZANA NAFE pa lamya kapena makalata kumanzere, kapena TITUMIZANI MAIME pansi pa tsamba.
