Zomakina ndi Zathupi za Tungsten Carbide

Tungsten carbide ndi aloyi yomwe ili ndi gawo lalikulu la ufa kuphatikiza tungsten carbide, titaniyamu carbide, ndi ufa wachitsulo monga cobalt, faifi tambala, ndi zina zotere, monga zomatira, zomwe zimapezeka kudzera munjira yazitsulo. Amagwiritsidwa ntchito kwambiri popanga zida zodulira mwachangu komanso zolimba, zolimba, komanso zida zobvala kwambiri popanga zida zoziziritsa kuzizira, ndi zida zoyezera.

Makina ndi mawonekedwe a tungsten carbide

1. High kuuma ndi kuvala kukana

Nthawi zambiri, pakati pa HRA86 ~ 93, amachepetsa ndi kuwonjezeka kwa cobalt. Kukana kuvala kwa tungsten carbide ndikofunikira kwambiri. Pakugwiritsa ntchito, ma carbides ndiatali nthawi 20-100 kuposa ma aloyi achitsulo osamva kuvala.

2. Mphamvu yapamwamba yotsutsana ndi kupindika.

Sintered carbide imakhala ndi zotanuka modulus ndipo chopindika chaching'ono kwambiri chimapezeka chikagwidwa ndi mphamvu yopindika. Mphamvu yopindika pa kutentha kwabwino ndi pakati pa 90 ndi 150 MPa ndipo kumtunda kwa cobalt, kumapangitsanso mphamvu yotsutsa kupindika.

3. Kukana dzimbiri

Nthawi zambiri amagwiritsidwa ntchito m'malo ambiri opangira mankhwala komanso zowononga chifukwa ma carbides nthawi zambiri amakhala amadzimadzi. More khola mankhwala katundu. Zinthu za Carbide zimakhala ndi acid-resistant, alkali-resistant, komanso ngakhale pa kutentha kwambiri.

4. Torsional mphamvu

Kuchuluka kwa torsion kuwirikiza kawiri kuposa chitsulo chothamanga kwambiri ndi carbide ndiye chinthu chomwe chimakondedwa kwambiri pakugwiritsa ntchito mothamanga kwambiri.

5. Compressive mphamvu

Magiredi ena a cobalt carbide ndi cobalt amachita bwino kwambiri akamapanikizika kwambiri ndipo amachita bwino kwambiri pakakamidwe kofikira 7 miliyoni kPa.

6. Kulimba

Magiredi a simenti a carbide okhala ndi zomangira zambiri amakhala ndi kukana kwambiri.

7. Kutentha kochepa kumavala kukana

Ngakhale pa kutentha kotsika kwambiri, carbide imakhalabe yabwino kuvala kukana ndipo imapereka ma coefficients otsika kwambiri popanda kugwiritsa ntchito mafuta.

8. Thermoharding

Kutentha kwa 500 ° C sikunasinthe ndipo pakadali kuuma kwakukulu pa 1000 ° C.

9. High matenthedwe madutsidwe.

Carbide yokhala ndi simenti imakhala ndi matenthedwe apamwamba kuposa chitsulo chothamanga kwambiri, chomwe chimawonjezeka ndi kuchuluka kwa cobalt.

10. Coefficient of thermal expansion ndi yaying'ono.

Ndiwotsika kuposa chitsulo chothamanga kwambiri, chitsulo cha carbon, ndi mkuwa, ndipo chimawonjezeka ndi kuwonjezeka kwa cobalt.
