Wear resistant coatings

摘要

A wear resistant coating (116) including a hard backing (118) including a metal alloy matrix dispersed with a plurality of hard particles; and a plurality of nano-layers (120) disposed on the hard backing (118) is provided. The plurality of nano-layers (120) has different characteristics from one another. A method of making a wear resistant coating (116) is provided. The method includes the steps of providing a substrate; disposing a hard backing (118); and disposing a plurality of nano-layers (120) on the hard backing (118).
