WearX® 210 Sprayed Coating Characteristics

Spray-Synthesis Process

WearX® 210 special cored wire is precisely formulated to produce sprayed 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, Cr2B.

The micro-alloying synthesis process at least two-fold increases the quantity of hard phases normally present in arc-sprayed coatings. These high quantity boride crystallites are responsible for excellent anti-wear properties.

WearX® 210 arc-sprayed coatings containing 10 wt.% chromium 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.
  • lamellae more ductile containing less sub-micron spherical boride crystallites.

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

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

WearX® 210 arc-sprayed coatings are tailored to be used in high temperature erosive environments in preference of WearX® 208 sprayed coatings.

The WearX® 210 cored wire can be:

  • arc sprayed,
  • arc sprayed and fused (thickness of about 0.080 inch),
  • deposited by TIG and MIG welding processes for forming ¼ inch thick overlays.

For low temperature, dry environment applications it is recommended to use WearX® 208 in preference of WearX® 210. With these applications WearX® 208 presents higher erosion resistance.
