High Toughness, Nanocomposite Carbide for Extreme Wear
Patents: (US 7,681,622)
PComP™ W is a cermet powder fabricated into a hierarchical structure using a patented process to engineer down to the nanoscale. The nanocomposite core contains nano and near-nano size WC (Tungsten Carbide) particles in a hard, corrosion resistant binder. This core is encased in a protective cladding that minimizes the adverse effects of the HVOF spraying process on the hard particles and assists in formation of a hierarchical coating structure.
The chart below depicts the comparison of PComP™ W with the widely used competing solutions of thermally sprayed tungsten carbide (WC) and electroplated hard chrome. As can be seen in the chart below, PComP™ W outperforms the competing solutions in almost all of the six critical parameters.
