molybdenum nuv rau cub cua sov hlau
Kev ua cov molybdenum tuaj yeem nyuaj vim ntau yam:
1. High hardness: Molybdenum yog ib qho nyuaj hlau, uas ua rau nws nyuaj rau txiav thiab zoo li siv ib txwm ua txoj kev.
2. High melting point: Molybdenum muaj qhov melting point heev, uas tuaj yeem ua rau cov cuab yeej hnav thiab thermal teeb meem thaum lub sij hawm machining.
3. Chav kub brittleness: Molybdenum yog nkig nyob rau hauv chav tsev kub, uas yuav ua rau muaj teeb meem nrog chip tsim thiab cov cuab yeej tawg thaum lub sij hawm machining.
4. Ua hauj lwm hardening: Molybdenum nquag ua hauj lwm hardening thaum lub sij hawm machining, uas tuaj yeem ua rau muaj zog txiav thiab cov cuab yeej hnav.
Txhawm rau kov yeej cov kev cov nyom no, cov txheej txheem tshwj xeeb machining, cov cuab yeej thiab cov cuab yeej txiav feem ntau xav tau thaum machining molybdenum. Tsis tas li ntawd, kev siv cov coolants tsim nyog thiab lubricants tuaj yeem pab tswj cov cua sov tsim thaum lub sijhawm ua haujlwm thiab txhim kho molybdenum machinability.
Molybdenum yog ductile, uas txhais tau hais tias nws tuaj yeem ncab lossis rub tawm yam tsis muaj kev tawg. Cov cuab yeej no ua rau nws tsim nyog rau ntau yam kev siv, suav nrog kev siv tshuab, qhov twg ductility yog ib qho tseem ceeb rau cov khoom kom zoo li tus thiab tsim tsis muaj cracking.
Molybdenum nws tus kheej tsis yog corrosive. Qhov tseeb, nws tau paub txog nws zoo heev tiv thaiv corrosion thiab oxidation ntawm qhov kub thiab txias. Qhov kev tiv thaiv corrosion no ua rau molybdenum yog ib qho khoom siv tseem ceeb hauv cov ntawv thov uas yuav tsum muaj kev cuam tshuam rau qhov chaw hnyav lossis cov khoom corrosive.
