WC-17Co 83/17 HVOF Spary Powder Equal To WOKA 3201 WOKA 3202 WOKA 3203 WOKA 3204 WOKA 3205 WOKA 3206 WOKA 3207

Chemical Composition:

Specification & Physical Properties:

Introduction:

These products are spheroidal, agglomerated and sintered powders for thermal spraying containing 83 % tungsten carbide as hard material and a cobalt matrix, which functions as a binder material for the carbide particles.

Coatings of these materials provide a higher toughness and fretting resistance than coatings of 88WC 12Co as a result of the higher cobalt levels.Coatings made from tungsten carbide-containing materials protect substrates from the effects of fretting, abrasive grains,particle erosion, sliding wear, hammer wear (impact resistance), cavitation and dynamic contact with hard surfaces.

They can be used as an alternative for hard chromium plating when these wear mechanisms are evident and for the recommended service environments and temperatures.Coatings of these materials are dense and show good bond strength when applied using the HVOF process or the APS process .
