Cobalt Qws thiab Hlau Description

Cobalt yog cov khoom siv ferromagnetic, tawv tsis tau nkig. Nws muaj qhov siab melting point thiab yog tawv-hnav ntawm qhov kub thiab txias. Nws muaj lub zog siab thiab muaj cov khoom zoo conduction.

Cobalt tau siv ntau hauv kev lag luam, kev lag luam, thiab kev siv tub rog. Cobalt feem ntau yog siv rau hauv cov roj teeb lithium-ion, thiab hauv kev tsim cov hlau nplaum, hnav-tiv taus thiab muaj zog alloys. Cobalt-based superalloys yog qhov tshiab. Tsis zoo li lwm cov superalloys, cobalt-base alloys yog tus cwj pwm los ntawm cov khoom-solution-strengthened austenitic (fcc) matrix nyob rau hauv uas ib tug me me npaum li cas ntawm carbide yog faib. Alloying ntsiab pom nyob rau hauv kev tshawb fawb ntawm Co-based alloys yog C, Cr, W, Ni, Ti, Al, Ir, thiab Ta. Lawv muaj qhov zoo dua weldability thiab thermal qaug zog tsis kam piv rau cov nickel raws alloy. Ntxiv mus, lawv muaj kev tiv thaiv corrosion zoo heev ntawm qhov kub thiab txias (980-1100 degree) vim lawv cov ntsiab lus chromium siab dua.
