Abstract: A metal matrix composites is used to laser clad a surface, such as a base metal machine element, and provide high wear and corrosion resistance, particularly useful for protecting surfaces in a salt water environment. The composites may comprise up to 25 wt % Mo and up to 20 wt % WC particles in a Nickel Alloy matrix; a nickel Alloy containing 5-30% Chromium, 0-20% Molybdenum, and 0-10% Tungsten or Niobium, with the balance being Nickel.
