WearX® 208 Sprayed Coating Characteristics

Spray-Synthesis Process

WearX® 208 special cored wires are precisely formulated to produce upon spraying coatings rich in borides (iron boride, complex boride of Fe-Cr, Fe-Ni-Cr,…). These borides are compounds possessing high hardness and excellent chemical stability.

Spray-Synthesis Process

Micro-Alloying Process

The unique micro-alloying process involving reaction between the metal sheet and core elements rich in boron produces sub-micron spherical crystallites of borides, such as Fe2B, (Fe,Cr)2B, (Fe-Cr-Ni)2BThe micro-alloying synthesis process at least two-fold increases the quantity of hard phases normally present in arc-sprayed coatings. This high quantity boride crystallites is responsible for excellent anti-wear properties.

Microstructure of WearX® 208 Arc Sprayed Coatings

Microstructure of WearX® 208 Arc Sprayed Coatings

WearX® 208 arc-sprayed coatings are tailored to contain more than 80% in volume of boride crystallites and 20% in steel. They are composed of:

  • lamellae very rich in sub-micron boride spherical crystallites (dark phases).
  • lamellae more ductile containing less sub-micron spherical boride crystallites (lighter phases).

The stacking of hard and more ductile phases forms a lamellar composite coating having very high wear resistance.

Hard phases ensure wear resistance while more ductile phases give coating cohesive strength and toughness required in wear resistant applications.
