Abstract
A material for water droplet erosion- and corrosion-resistant coatings, comprising metallic tungsten alloyed with carbon in a substantially uniform nano-structure that is substantially free of oxygen, other than at surface portions exposed to air or moisture. The coatings disclosed may be particularly resistant to water droplet erosion when coated onto gas or steam turbine blades.
Claims49
An erosion- and corrosion-resistant material coated on a substrate, the material comprising metallic tungsten alloyed with carbon in the form of a matrix of metallic tungsten with interdispersed tungsten carbide nanoparticles in a substantially uniform nano-structure that is substantially free of oxygen, other than at surface portions exposed to air or moisture, wherein the material has a columnar crystalline microstructure.
