Bubuk Cast Tungsten Carbide Bunder
Bunder Cast Tungsten Carbide (SCTC) Powder minangka bubuk abu-abu peteng sing digawe kanthi spheroidisasi utawa atomisasi suhu ultra-dhuwur. SCTC minangka kristal dendritik sing kasusun saka WC lan W 2 Struktur mikro kaya wulu yaiku ≥ 90%. Uga nduweni stabilitas kimia sing apik lan titik leleh dhuwur (2525 ℃). Atose dhuwur (≥2700 HV0.1), flowability cepet, lan tambah nyandhang lan resistance karat ndadekake banget populer kanggo nggawe overlay hardfacing.
SCTC digunakake kanggo nyiapake bubuk bit matriks PDC, bubuk Plasma Arc Welding (PTAW), bubuk Laser Cladding, bahan welding semprotan, elektroda (kabel) sing tahan nganggo karbida semen. Tujuan utamane yaiku kanggo nguatake permukaan sing tahan nganggo. utawa ndandani lumahing rusak kanggo pertambangan, minyak & gas, metalurgi, mesin konstruksi, mesin pertanian, lan industri baja.
