Eutalloy 15999

Heterogeneous metal powder mixture of diluted matrix component and tungsten carbides. Coatings with NiCrBSi matrix and embedded, finely dispersed hard materials.
High wear resistance against erosion and abrasion. For operating temperatures up to 700 °C. Corrosion resistant. Optimum surface protection with coating thicknesses of 0.5 - 3 mm.

Technical data
Hardness [HRC]: 59*
Hardness [HV]: 1,500*
Grain size distribution [μm]: 20 - 125
Melting interval (Sol./Liq.) [°C]: 970 - 1,060
Working temperature [°C]: 1,040

Applications
For thermal spraying with simultaneous melting of unalloyed, low-alloy and high-alloy steels and the corresponding cast steel grades as well as cast iron materials and nickel alloys.

Typical application examples are
Erosion, abrasion and corrosion-resistant protective coatings for blower blades, guides for rolling mills, scrapers, molding sand blades as well as brackets and plates for ceramic press molds.

Processing instructions
Remove damaged material. Clean spraying areas. During spraying, adjust the heat to the component, its material and dimensions. To protect the surface against oxidation, spray on a thin layer and melt in while adding more powder. Allow to cool in still air.

Preheating:
GJL: 600 - 800 °C
Steel: 300 - 400 °C

*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.
