for highly wear-resistant coatings
Eutalloy RW 12999
Heterogeneous metal powder mixture of diluted matrix component and tungsten carbides. Coatings with NiCrCoBSi matrix and embedded, finely dispersed hard materials. Resistant to abrasion under pressure and/or light impact stress. Smooth and highly polishable surface when melted.
Technical data
Coating hardness [HRC]: ~63*
Tungsten carbide/matrix: 40/60
Grain size distribution [μm]: 38 - 125
Melting interval (Sol./Liq.) [°C]: 960 - 1,150
Working temperature [°C]: 1,040
Density [g/cm3]: 7.8
Applications
For thermal spraying with subsequent melting of unalloyed, low-alloy and high-alloy steels and the corresponding cast steel grades.
Typical applications are
Press and conveyor screws, mixer and fan components; machines for extracting, conveying and processing sand
and processing of sand; parts ("glass levels") of molds for the production of hollow glass.
Processing instructions
Remove damaged material. Round off or chamfer edges. Clean spray areas, preheat to 50 - 150 °C and roughen. Spray to the desired layer thickness in the preheated state. Do not exceed a layer thickness of 1.5 mm. Heat the workpiece to working temperature and melt the spray coating (within 15 minutes). The working temperature can be recognized by the metallic sheen of the molten state. Do not overheat/overtime. Allow to cool in still air.
Spraying device: CastoDyn DS 8000
Melting: Flame burner (acetylene, neutral to reducing), inert gas furnace, (HF induction)
Shrinkage: 20 % during melting
*The achievable hardness values depend on the selected spraying parameters, preheating temperatures, etc. No guarantee can therefore be given that the hardness values will be achieved.
