Specification & Physical Properties:

Introduction:

BODA WC-10Ni products are spheroidal, agglomerated and sintered powders for thermal spray containing a uniform distribution of 90 % tungsten carbide with medium sized carbide grains as a hard phase and 10 % 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 fretting, abrasion, hammer and sliding wear.  WC-10Ni 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. WC-10Ni series coatings exhibit higher hardness compared to coatings of WC-17Ni (Woka 3500 series
products), but have lower toughness. The absence of cobalt allows Woka 3300 series 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.
