Spherical Cast Tungsten Carbide Poda
Spherical Cast Tungsten Carbide (SCTC) Poda ni poda ya kijivu iliyokolea iliyotengenezwa na spheroidization ya halijoto ya juu sana au atomization. SCTC ni fuwele ya dendritic inayoundwa na WC na W 2 Muundo mdogo unaofanana na manyoya ni ≥ 90%. Pia ina uthabiti bora wa kemikali na kiwango cha juu cha kuyeyuka (2525 ℃). Ugumu wa hali ya juu (≥2700 HV0.1), mtiririko wa haraka, na kuongezeka kwa uchakavu na upinzani wa kutu hufanya iwe maarufu sana kutengeneza viwekeleo vya nyuso ngumu.
SCTC hutumika kuandaa poda ya biti za matrix ya PDC, poda ya Plasma Arc Welding (PTAW), poda ya Laser Cladding, vifaa vya kulehemu vya kunyunyizia, elektroni zinazostahimili CARBIDE (waya), n.k. Madhumuni ya msingi ni kuimarisha mapema nyuso zinazostahimili uchakavu. au kurekebisha nyuso zilizochakaa kwa uchimbaji madini, mafuta na gesi, madini, mitambo ya ujenzi, mashine za kilimo na viwanda vya chuma.
