Application & selection

Tungsten-carbide-based feedstocks are selected by the carbide identity and, where present, the binder chemistry. Powder manufacturing route and particle size are also important when selecting material for a coating process.

Match the specified size distribution to the spray equipment and feeding system. Agglomerated-and-sintered powder and crushed powder should be distinguished when checking morphology, flow and the applicable product data. Coating properties are established with the chosen equipment, substrate and test conditions.

Details to confirm for this product

• Required carbide and binder composition and the named grade.
