Cov nyhuv ntawm cobalt cov ntsiab lus hauv cemented carbide rau cov khoom siv

Cov ntsiab lus cobalt ntawmcemented carbidemuaj qhov cuam tshuam loj rau cov khoom ntawm cov khoom, suav nrog hardness, toughness, hnav tsis kam thiab cuam tshuam tsis kam.Hauv qab no yog kev sib raug zoo ntawm cov ntsiab lus cobalt ntawm cemented carbide thiab nws cov kev ua tau zoo

1. Hardness
Cemented carbidenrog qis cobalt cov ntsiab lus (xws li tsawg dua 10%) feem ntau muaj hardness siab dua vim hais tias kev sib cog lus ntawm tungsten carbide hais tsis muaj zog thiab tsis yooj yim rau plastically deform.Hard alloy nrog ntau dua cobalt cov ntsiab lus (xws li ntau tshaj 20%) Lub hardness ntawm high-zoo alloys kuj yog tsawg vim hais tias cov cobalt cov ntsiab lus nce thiab cov nyhuv bonding zog, ua rau cov khoom muaj feem xyuam rau cov yas deformation thaum muaj kev ntxhov siab.
2. Toughness:
Carbidenrog cov ntsiab lus cobalt ntau dua muaj zog dua vim tias qhov sib ntxiv ntawm cobalt ua rau cov khoom muaj zog, ua rau nws tsis tshua tawg thaum raug cuam tshuam los yog kev co.
· Cemented carbide nrog cov ntsiab lus qis cobalt muaj qhov tsis zoo thiab ua rau tawg lossis tawg thaum cuam tshuam.

3. Hnav tsis kam:
Carbide nrog cov ntsiab lus cobalt ntau dua muaj qhov hnav zoo dua vim tias cobalt tuaj yeem muab kev sib raug zoo dua thiab hnav tsis kam.
Carbidenrog cov ntsiab lus qis cobalt muaj qhov tsis zoo hnav tsis zoo vim tias kev sib cog lus ntawm tungsten carbide hais tsis muaj zog thiab yooj yim poob thaum hnav.
4. Kev cuam tshuam tsis kam:
Carbide nrog cov ntsiab lus cobalt ntau dua muaj qhov cuam tshuam zoo dua vim tias qhov sib ntxiv ntawm cobalt ua rau cov khoom muaj zog thiab tsis kam ua kom tawg.
Carbide nrog qis cobalt cov ntsiab lus muaj kev cuam tshuam tsis zoo thiab ua rau tawg thaum cuam tshuam.

5. Corrosion kuj
Carbidenrog cov ntsiab lus cobalt ntau dua muaj kev tiv thaiv corrosion zoo dua vim tias cobalt muab kev tiv thaiv zoo rau oxidation thiab corrosion.
Carbide nrog cov ntsiab lus tsis tshua muaj cobalt muaj qhov tsis zoo corrosion thiab nws yooj yim rau corrosion nyob rau hauv ib puag ncig hnyav.
