Plasma transfer arc welding (PTAW) for depositing tungsten carbide-nickel cermet coating for corrosion

PTAW is a cermet deposition method that may produce thick coating (up tp 3 mm). Cermet deposit by this method has shown high wear and corrosion resistance. The tungsten carbide (WC) content will be varied (0, 35, 50 65 wt%) to evaluate its morphology, chemical composition and corrosion behavior of t...
