Tungsten carbide – 10% cobalt 4% chromium

55586C is a spherical powder manufactured by agglomerating and sintering a formulation of 86% tungsten carbide with 10% cobalt and 4% chromium by weight. The addition of chromium to the matrix improves the resistance to corrosion and increases thermal stability versus WC-12Co or WC-17Co coatings. It has been developed for spraying with the CastoJet CJK5 system which is a High Pressure HVOF using kerosene as liquid fuel. 55586C powder is also suitable for other HVOF systems or plasma spraying. 55586C sprayed coatings are hard and dense with high bond strengths on a wide variety of metallic substrates. They resist exceptionally well where both wear and corrosion are required for service temperatures up to 500°C.
