Technology Marketing Summary

Hardface Coating Systems provides a family of coatings or surface materials on substrate metal alloy systems for wear and corrosion applications. A titanium boron coating is applied as a liquid to the surface of another metallic object. As the liquid cools, it bonds to the surface and undergoes a chemical reaction that provides superior wear and thermal stress properties. The metallic coating combines the performance of heat treatment and alloys, bonded to the surface of the substrate.


Hardface Coating Systems creates a hard, high wear, and corrosion-resistant surface. The Coating can be used on a variety of metal substrates and does not drastically affect mechanical heat treatments.

  • No heat treatment needed.
  • Directly bonds to the surface of the substrate.
  • Can be applied on finished components or fabricated on sheet materials.

Hardface coating systems and methods for metal alloys and other materials for wear and corrosion resistant applications
The present disclosure relates generally to hardface coating systems and methods for metal alloys and other materials for wear and corrosion resistant applications. More specifically, the present disclosure relates to hardface coatings that include a network of titanium monoboride (TiB) needles or whiskers in a matrix, which are formed from titanium (Ti) and titanium diboride (TiB.sub.2) precursors by reactions enabled by the inherent energy provided by the process heat associated with coating deposition and, optionally, coating post-heat treatment. These hardface coatings are pyrophoric, thereby generating further reaction energy internally, and may be applied in a functionally graded manner. The hardface coatings may be deposited in the presence of a number of fluxing agents, beta stabilizers, densification aids, diffusional aids, and multimode particle size distributions to further enhance their performance characteristics.
