55583C is a spherical powder manufactured by agglomerating and sintering a formulation of 83% tungsten carbide with 17% cobalt by weight. It has been developed for spraying with the CastoJet CJK5 system which is a High Pressure HVOF using kerosene as liquid fuel. 55583C powder is also suitable for other HVOF systems or plasma spraying. 55583C sprayed coatings are hard and dense with high bond strengths on a wide variety of metallic substrates. They are tougher with a better fretting and impact resistance than WC-12Co coatings. They resist exceptionally well to low stress abrasion, fretting wear and hard particle erosion for service temperatures up to 500°C.
