ABSTRACT:
Erosion resistance is imparted to a metallic substrate without an attendant loss of fatigue life in the substrate by applying to the substrate a first layer comprising palladium, platinum or nickel in direct contact with the substrate and then applying a second layer which overcoats the first layer, the second layer being comprised of a tungsten-carbon alloy or a material formed of a tungsten matrix having dispersed tungsten-carbon compound phases therein. In another embodiment erosion resistance is imparted by employing a coating which comprises a first ductile layer on the substrate of palladium, platinum or nickel; a second layer comprising substantially pure tungsten; and a third layer comprising a material formed of a tungsten-carbon alloy or a material formed of a tungsten matrix having dispersed tungsten-carbon compound phases.
