Specification & Physical Properties :

Introduction :

BODA WC-12Ni products are spheroidal, agglomerated and sintered powders for thermal spray containing a uniform distribution of 88 % tungsten carbide with medium sized carbide grains as a hard phase and 12 % nickel as a binder metal.
The finer powder particle size distributions produce very tough and dense coatings that can often be used in the “as-
sprayed” condition without post-coat finishing.Coatings made from tungsten carbide materials resist fret-
ting, abrasion, hammer and sliding wear. BODA WC-12Ni series products are most often used for abrasion-resistant coatings in dry environments. Their use at atmospheric temperatures
above 500 °C (930 °F) is not recommended to prevent oxidation of the tungsten carbide. The corrosion resistance of WC-Ni is generally better than that of WC-Co coatings in similar environments, but not as good as coatings of WC-Co-Cr. BODA WC-12Ni coatings exhibit higher hard-ness compared to coatings of WC-17Ni, but have lower toughness. They have lower hard-
ness but better toughness than coatings from WC-10Ni. The absence of cobalt allows
BODA WC-12Ni coatings to be used in radioactive environments.
HVOF coatings of these materials are dense, show good
bond strength and are more homogeneous than coatings
applied using atmospheric plasma spray or combustion
powder Thermospray ™ coatings.
