Specification & Physical Properties:

Introduction:

These products are spheroidal, agglomerated and sintered powders for thermal spraying containing 86 % tungsten carbide as hard material and a cobalt-chromium matrix, which functions as a binder material for the carbide particles.
The products are particularly suitable for applications where both wear and corrosion resistance is required. Chromium in
the matrix improves corrosion resistance while the fine carbide grains provide the abrasive, erosive and fretting wear
properties of a tungsten carbide-cobalt based material.Thermal sprayed coatings of these materials are excellent alternatives to hard chromium plating. The coatings provide excellent wear and corrosion resistance and can be ground
and superfinished to surface finishes that are similar to chromium plating. HVOF coatings of these materials are dense,
show good bond strength. They also exhibit smooth, assprayed surfaces that are useful in applications where grind-
ing cannot be done or is not required.
