Bolfoarmige Cast wolframkarbidpoeder

Spheical Cast Tungsten Carbide (SCTC) Poeder is in donkergriis poeder makke troch ultra-hege temperatuer spheroidization of atomization. SCTC is in dendrityske kristal gearstald út WC en W 2 De feather-like mikrostruktuer is ≥ 90%. It hat ek poerbêste gemyske stabiliteit en in heech smeltpunt (2525 ℃). De hege hurdens (≥2700 HV0.1), snelle flowability, en ferhege wear en corrosie ferset meitsje it tige populêr te meitsjen hardfacing overlays.

SCTC wurdt brûkt foar it tarieden fan PDC matrix bits poeder, Plasma Arc Welding (PTAW) poeder, Laser Cladding poeder, spray welding materialen, cemented carbid wear-resistant elektroden (wire), ensfh It primêre doel is om pre-fersterke wear-resistant oerflakken of reparearje droegen oerflakken foar mynbou, oalje & gas, metallurgy, boumasjines, lânboumasines, en stielyndustry.
