FeCrBSi wire material with iron weight content as high as 80%. The coating was prepared by twin-wire arc spraying processing. The chemical compositions of the coating,
as well as phase components were analyzed by energy-dispersive spectroscopy and
x-ray diffraction method. The surface roughness, porosity, and cross-sectional morphology were further characterized. In-boiler test was also carried out.
The low thickness loss of the tube indicates a promising application future in sludge boilers.
The coating hardness is close to that of the commercial Armacor M and Armacor C materials.
It can Equivalent to TAFA 95MAX, Armacore M.
Surface Preparation
Surface should be clean, white metal, with no oxides (rust), dirt, grease, or oil on the surface to be coated. Note: It is best not to handle surfaces after cleaning. Recommended method of preparation is, to grit blast with 24 mesh aluminum oxide, rough grind, or rough machine in a lathe.
Typical Applications
Boiler Tubes & Tube Shields,Yankee Dryer Rolls
Anti-Skid ,Fan Blades
Drill Collars.
