Tungsten carbide – 12% cobalt

55588C is a spherical powder manufactured by agglomerating and sintering a formulation of 88% tungsten carbide with 12 % 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. 55588C powder is also suitable for other HVOF systems or plasma spraying. 55588C sprayed coatings are hard and dense with high bond strengths on a wide variety of metallic substrates. They resist exceptionally well to low stress

abrasion, fretting wear and hard particle erosion for service temperatures up to 500°C.
