Tupa Poda ya Carbide ya Tungsten

Poda ya Tungsten Carbide (CTC) imetengenezwa kwa kuyeyuka na kusagwa W na WC na ni chembechembe za kijivu iliyokoza zisizo za kawaida na kiwango cha juu myeyuko (2525℃), ugumu wa juu (≥ 2000 HV0.1), na upinzani bora wa kuvaa.

CTC hutumika kuandaa poda ya biti za matrix ya PDC, poda ya Kuchomelea Safu ya Plasma (PTAW), vifaa vya kulehemu vya kupuliza, elektroni zinazostahimili CARBIDE (waya), n.k. Madhumuni ya msingi ni kuimarisha mapema nyuso zinazostahimili uchakavu au kurekebisha nyuso zilizochakaa. kwa madini, mafuta na gesi, madini, mashine za ujenzi, mashine za kilimo, na viwanda vya chuma.
